    Life through the 'Varanger ice ages': microfossil record of late Neoproterozoic glacial-interglacial units from arctic Norway2018Inngår i: Geological Society of America Abstracts with Programs, Geological Society of America, 2018, Vol. 50Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The late Neoproterozoic strata in Finnmark (Arctic Norway) provide a good sedimentary record of Neoproterozoic glaciations on the Baltica paleocontinent. The lower Vestertana Group exposed on the Digermulen Peninsula contains two glaciogenic units, the Smalfjord and Mortensnes formations. Chemostratigraphic correlation dated the Smalfjord diamictite to the Marinoan glaciation (650-635 Ma), yet its age was also proposed to be older, per correlation to glacial units in central and southern Scandinavia. The diamictites are bracketing shales and siltstones of the interglacial Nyborg Formation. Stratigraphic, paleontological, and sedimentological data are presented from the interglacial-glacial succession, investigated by the Digermulen Early Life Research Group. Palynological analysis yielded well-preserved organic-walled microfossils (OWM) from the Nyborg Fm., and from fine-grained diamictite matrix in the Mortensnes Fm. via a modified extraction method.

    The interglacial Nyborg Fm. hosts a moderate diversity assemblage of prokaryotic and eukaryotic OWM, as well as acanthomorphic acritarchs such as Ceratosphaeridium, ?Cavaspina, and a novel process-bearing form. Organically preserved, enigmatic multicellular eukaryotic fossils occur in the upper Nyborg Fm. The Mortensens glacial assemblage is less diverse and contains bacterial filaments, leiosphaerids, toroidal forms, and Micrhystridium-type minute acanthomorphs.

    The presence of Doushantuo-Pertatataka type acritarchs in the Nyborg Fm., and small acanthomorphs in the Mortensnes diamictite corroborate an early Ediacaran age for the interglacial-glacial succession on Digermulen. In addition to the trace fossil and body-fossil record of Ediacara-biota in the overlying Stáhpogieddi Formation, the microfossil biostratigraphy suggests Marinoan and Gaskiers glaciation equivalent ages of the Varanger glaciations in Finnmark. Protistan diversity in the succession declined through and following the glaciation, until late Ediacaran.

    Unusual organic-walled microfossil from the late Neoproterozoic Nyborg Formation, Digermulen Peninsula, Arctic Norway2017Inngår i: ISECT 2017, 2017Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The late Neoproterozoic Nyborg Formation is exposed in the Tanafjord area, Finnmark, Arctic Norway, on Digermulen and Varanger Peninsulas. The succession is composed of ~400 m of interbedded shales, siltstone and purple to grey sandstone, deposited between Neoproterozoic low latitude glacial deposits. The Nyborg Fm. lies on top of the Smalfjord diamictite, and is overlain by the Mortensnes diamictite (the latter was attributed to both Marinoan (650-635 Ma) and Gaskiers (579 Ma) glaciations) and the Ediacaran-Cambrian Stáhpogieddi Formation. Thus, the Nyborg Fm. represents late Neoproterozoic, probably the last Cryogenian interglacial interval. Presented material was collected in 2014 by members of Digermulen Early Life Research Group, from organic-rich, grey-green shales and siltstones of the Nyborg Mbr. D, uppermost Nyborg Fm. between Árasulluokta and Guvssájohka valleys. Organic-walled microfossils were extracted from shale via standard palynological acetolysis in hydrofluoric acid, and studied via light and scanning electron microscopy. Microfossils from the Nyborg Fm. include Synsphaeridium-type aggregated cells, unbranched bacterial filaments (Polythrichoides and Siphonophycus), sphaeromorph and envelope-bearing acritarchs (leiosphaerids, Stictosphaeridium, Simia), and previously unrecognized aggregated tubular microfossils. These taxa are long-ranging, but common in glacial-interglacial units worldwide, and thus broadly corroborate the Cryogenian age of the Nyborg sediments. The novel fossil, up to 300 μm in size, is a parenchymatous meshwork of interconnected organic-walled tubes that terminate in cup-shaped apices 4-11 µm in diameter. Irregular tube clusters are truncated both in macerates and in thin sections, suggesting post mortem transport. Elemental EDXS analysis indicates that extracted meshwork microfossils are predominantly composed of carbonaceous material and also associated with small amounts of titanium and vanadium. Considering the branching and adjoined body plan of carbonaceous fossil, it was likely multicellular and of eukaryotic affinity. As such, it may represent an important step in the evolution of complex multicellularity and morphological complexity several million years before the appearance of Ediacaran organisms.

    Yochelcionella (Mollusca, Helcionelloida) from the lower Cambrian of North America2008Inngår i: Bulletin of Geosciences, ISSN 1214-1119, E-ISSN 1802-8225, Vol. 83, nr 1, s. 23-38Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Five named species of the helcionelloid mollusc genus Yochelcionella Runnegar & Pojeta, 1974 are recognized from the lower Cambrian (Cambrian Series 2) of North America: Yochelcionella erecta (Walcott, 1891), Y. americana Runnegar & Pojeta, 1980, Y. chinensis Pei, 1985, Y. greenlandica Atkins & Peel, 2004 and Y. gracilis Atkins & Peel, 2004, linking lower Cambrian outcrops along the present north-eastern seaboard. Yochelcionella erecta, an Avalonian species, is described for the first time, other species are derived from Laurentia. A revised concept of the Chinese species, Y. chinensis, is based mainly on a large sample from the Forteau Formation of western Newfoundland and the species may have stratigraphic utility between Cambrian palaeocontinents.

    Palaeobiology, taphonomy and stratigraphic significance of the trilobite BUENELLUS from the Sirius Passet Biota, Cambrian of North Greenland2007Inngår i: Memoirs of the Association of Australasian Palaeontologists, ISSN 0810-8889, Vol. 34, s. 401-418Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Sirius Passet Biota, collected from the lower Buen Formation (Cambrian Series 2, Stage 3), North Greenland, contains one species of trilobite, the nevadiid Buenellus higginsi Blaker, 1988. The species shows considerable morphological variation, especially in exoskeletal width. Many specimens of B. higginsi show some form of exceptionally preserved, non-biomineralised tissue. Structures interpreted as alimentary tracts and probable digestive glands are commonly preserved by silica and limonite. Antennae are rarely preserved, apparently through replication in clay minerals. Tendinous bars in the axial region also seem to be preserved by replication in clay minerals. Mineral-filled gut tracts in B. higginsi suggest they were fluid-filled at the time of burial, and that the species was a non-durophagous predator. Healed injuries, some of which are the result of unsuccessful predaceous attacks, are uncommon in B. higginsi. Other exoskeletons show evidence of post-mortem disruption, perhaps scavenging. Buenellus higginsi, one of the earliest known trilobites from Laurentia, seems to have played an important role in the Sirius Passet ecosystem, serving both as predator on, and prey for, contemporary animals.

    Late Cretaceous (Campanian) actinopterygian fishes from the Kristianstad Basin of southern Sweden2016Inngår i: Mesozoic Biotas Of Scandinavia And Its Arctic Territories, Geological Society, 2016, s. 277-292Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [en]

    Although a diverse range of aquatic vertebrates are documented from the Upper Cretaceous (mid-Campanian) marine strata of the Kristianstad Basin in southern Sweden, only chondrichthyans and marine amniotes have been described in detail to date. In contrast, coeval actinopterygians are virtually unreported, yet their remains are extremely abundant at most sampled localities. A comprehensive assessment of these fossils has identified the first Late Cretaceous actinopterygian fauna from the Fennoscandian Shield, incorporating indeterminate lepisosteids, the durophagous pycnodontid Anomoeodus subclavatus, the predatory pachycormid Protosphyraena sp., a large ichthyodectid, pachyrhizodontids resembling Pachyrhizodus, the enchodontid Enchodus cf. gladiolus and indeterminate small teleosts. These taxa are diagnosed mainly from isolated teeth and scales, implying substantial taphonomic loss prior to burial. Moreover, the prolific recovery of actinopterygian skeletal remnants in recent excavations suggests that historical collecting biases, rather than ecological paucity, have contributed to their under-representation in the Swedish Cretaceous record. Palaeobiogeographically, the Kristianstad Basin actinopterygians show compositional resemblance to assemblages from the Northern European Platform and the Western Interior Seaway of North America, advocating distributional communication across the Boreal proto-Atlantic Ocean.

    Static Dental Disparity and Morphological Turnover in Sharks across the End-Cretaceous Mass Extinction2018Inngår i: Current Biology, ISSN 0960-9822, E-ISSN 1879-0445, Vol. 28, nr 16, s. 2607-2615Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Cretaceous-Palaeogene (K-Pg) mass extinction profoundly altered vertebrate ecosystems and prompted the radiation of many extant clades [1, 2]. Sharks (Selachimorpha) were one of the few larger-bodied marine predators that survived the K-Pg event and are represented by an almost-continuous dental fossil record. However, the precise dynamics of their transition through this interval remain uncertain [3]. Here, we apply 2D geometric morphometrics to reconstruct global and regional dental morphospace variation among Lamniformes (Mackerel sharks) and Carch-arhiniformes (Ground sharks). These clades are prevalent predators in today's oceans, and were geographically widespread during the late Cretaceous-early Palaeogene. Our results reveal a decoupling of morphological disparity and taxonomic richness. Indeed, shark disparity was nearly static across the K-Pg extinction, in contrast to abrupt declines among other higher-trophic-level marine predators [4, 5]. Nevertheless, specific patterns indicate that an asymmetric extinction occurred among lamniforms possessing lowcrowned/triangular teeth and that a subsequent proliferation of carcharhiniforms with similar tooth morphologies took place during the early Paleocene. This compositional shift in post-Mesozoic shark lineages hints at a profound and persistent K-Pg signature evident in the heterogeneity of modern shark communities. Moreover, such wholesale lineage turnover coincided with the loss of many cephalopod [6] and pelagic amniote [5] groups, as well as the explosive radiation of middle trophic-level teleost fishes [1]. We hypothesize that a combination of prey availability and post-extinction trophic cascades favored extant shark antecedents and laid the foundation for their extensive diversification later in the Cenozoic [7-10].

    The Bromell fossil collection at Uppsala University, Sweden: its history and the people behind it2013Inngår i: GFF, ISSN 1103-5897, E-ISSN 2000-0863, Vol. 135, nr 1, s. 3-17Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Remains of 17(th) century cabinets of curiosity collections are held at the Museum of Evolution, Uppsala University, Sweden. Some of the oldest date back to the 1650s, and were included in the collection of Archiater, i.e. physician to the Crown, von Bromell (1679-1731). He is also known for publishing the first series of papers in Sweden to exclusively deal with palaeontology. Throughout his life he acquired specimens by collecting, buying or receiving in exchange to add to those he inherited from his father Olaus Bromelius, a famous botanist and physician. Information on the labels gives a glimpse of his network of friends, colleagues and fellow collectors, such as Kilian Stobaeus, Lars Roberg, Emanuel Swedenborg, Elias Brenner and Johan Dobelius. When Bromell died, his vast collections of books, coins, furniture, conchs, stuffed animals, minerals and fossils were sold off. The minerals and fossils were split up and owned by various persons during the following century. Parts owned by A. Lagerberg between the years 1746 and 1776 were bought in 1796 by Johan Afzelius and donated to Uppsala University at his death. Fossils and minerals earlier described by Bromell were in the care of The Royal Society of Science in Uppsala at least by 1791. Through the Institute of Geology, fossils accumulated over the centuries at Uppsala University eventually came together under the same roof in 1932, under professor Carl Wiman's care at the then newly erected Palaeontology museum building. Today, about 300 fossils from the Bromell collection are preserved at the museum.

    An orthothecid hyolith with a digestive tract from the early Cambrian of Bornholm, Denmark2018Inngår i: GFF, ISSN 1103-5897, E-ISSN 2000-0863, Vol. 140, nr 1, s. 25-37Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The hyolith assemblage from the early Cambrian of Bornholm, Denmark, shows a higher diversity than contemporary assemblages in Baltoscandia. The most common species in the Green Shales (Laesa Formation, Norretorp Member, Cambrian Stage 3), is Hyolithes [=Hyolithus] (Orthotheca) johnstrupi Holm, 1893. A specimen of this species shows a well-preserved and almost complete digestive tract, folded into an approximately 22mm long chevron-like structure comprised of at least 20 arcuate loops on the ventral side and a flattened, gently sinuous to straight anal tube on the dorsal side. The thin, phosphatic outer shell layer of the conch is crushed under the digestive tract due to compaction while the digestive tract is preserved in three dimensions and appears undisturbed. The shape of the digestive tract is similar to that of the middle Cambrian Guduguwan hardmani (Etheridge) from Australia and the lower Cambrian specimens from Russia described by Mekova & Sysoev. The Danish specimen is probably an adult, lending support to the idea that the orthothecid digestive tract becomes more complex during ontogeny. Hyolithus (Orthotheca) johnstrupi is revised and here referred to Circotheca Sysoev, 1958.

    Molecular characterization of Borrelia burgdorferi isolated from Ixodes ricinus in northern Sweden.1992Inngår i: Scandinavian Journal of Infectious Diseases, ISSN 0036-5548, E-ISSN 1651-1980, Vol. 24, nr 2, s. 181-188Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Ixodes ricinus ticks, harbouring Borrelia burgdorferi, were found in an area in northern Sweden, not thought to be endemic for Lyme borreliosis. This investigation took place at Norrbyskär, an island situated in the Bothnian Gulf, 63 degrees 33'N/19 degrees 52'E. One of 42 nymphal and 8/43 adult I. ricinus ticks collected carried spirochetes as seen by phase contrast microscopy. Pure bacterial cultures were obtained from 2 of the ticks. Western blot analysis using species-specific monoclonal antibodies showed that the isolated spirochetes were B. burgdorferi. The identity of the isolated spirochetes was confirmed by DNA amplification using B. burgdorferi OspA and flagellin gene specific oligonucleotides as well as partial DNA sequencing of the respective OspA and flagellin genes. The 2 isolated spirochaete populations were different as shown by their protein profiles in sodium dodecyl sulphate polyacrylamide gels. Moreover, the demonstration of Lyme borreliosis in a patient from the island of Norrbyskär indicates the need for clinical consideration of this disease in northern Sweden.

    New records of brachiopods and crinoids from the Silurian (Wenlock) of the southern Urals, Russia2018Inngår i: GFF, ISSN 1103-5897, E-ISSN 2000-0863Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Crinoids and brachiopods are described from the Silurian Uzyan Formation of the Zilair Zone in the southern Urals. The occurrence of the graptolites Coronograptus praedeubeli suggests a late Homerian (Wenlock) age for the strata. A new disparid crinoid, Cicerocrinus gracilis Donovan sp. nov., is the oldest known member of this genus. It has a long, flexible and homeomorphic column, and a tall bryozoan palaeontology terminology (IBr2) (second primibrachial) axillary. All species of Cicerocrinus described previously have been limited to the Ludlow of the British Isles, Sweden and Estonia, and the Pridoli of Estonia. The poorly preserved brachiopod fauna is represented by small atrypid (Atrypa? sp.) and dalmanellid brachiopods (Levenea? sp.). The reported assemblage generally inhabited deep-water environments.

    Evaluating methodologies for species delimitation: the mismatch between phenotypes and genotypes in lichenized fungi (Bryoria sect. Implexae, Parmeliaceae)2019Inngår i: Persoonia, ISSN 0031-5850, E-ISSN 1878-9080, Vol. 42, s. 75-100Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In many lichen-forming fungi, molecular phylogenetic analyses lead to the discovery of cryptic species within traditional morphospecies. However, in some cases, molecular sequence data also questions the separation of phenotypically characterised species. Here we apply an integrative taxonomy approach - including morphological, chemical, molecular, and distributional characters - to re-assess species boundaries in a traditionally speciose group of hair lichens, Bryoria sect. Implexae. We sampled multilocus sequence and microsatellite data from 142 specimens from a broad intercontinental distribution. Molecular data included DNA sequences of the standard fungal markers ITS, IGS, GAPDH, two newly tested loci (FRBi15 and FRBi16), and SSR frequencies from 18 microsatellite markers. Datasets were analysed with Bayesian and maximum likelihood phylogenetic reconstruction, phenogram reconstruction, STRUCTURE Bayesian clustering, principal coordinate analysis, haplotype network, and several different species delimitation analyses (ABGD, PTP, GMYC, and DISSECT). Additionally, past population demography and divergence times are estimated. The different approaches to species recognition do not support the monophyly of the 11 currently accepted morphospecies, and rather suggest the reduction of these to four phylogenetic species. Moreover, three of these are relatively recent in origin and cryptic, including phenotypically and chemically variable specimens. Issues regarding the integration of an evolutionary perspective into taxonomic conclusions in species complexes, which have undergone recent diversification, are discussed. The four accepted species, all epitypified by sequenced material, are Bryoria fuscescens, B. glabra, B. kockiana, and B. pseudofuscescens. Ten species rank names are reduced to synonymy. In the absence of molecular data, they can be recorded as the B. fuscescens complex. Intraspecific phenotype plasticity and factors affecting the speciation of different morphospecies in this group of Bryoria are outlined.

    Reassessment of the earliest documented stegosaurian fossils from Asia2016Inngår i: Cretaceous research (Print), ISSN 0195-6671, E-ISSN 1095-998X, Vol. 68, s. 61-69Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In 1929, the famous Swedish palaeontologist Carl Wiman documented the first unequivocal stegosaurian dinosaur fossils from Asia. His material comprised an isolated dermal spine, together with a dorsal vertebra that was briefly described but never figured. Since then these remains have languished in obscurity, being noted in some stegosaur review articles but often ignored altogether. However, recent auditing of the Museum of Evolution palaeontological collection at Uppsala University in Sweden has led to the rediscovery of Wiman's original specimens, as well as two additional previously unrecognised stegosaurian dorsal vertebrae. All of these bones derive from the Lower Cretaceous (Berriasian-Valanginian) Mengyin Formation of Shandong Province in eastern China, and are morphologically compatible with the stratigraphically proximal stegosaurian taxon Wuerhosaurus from the Valanginian-Albian Tugulu Group in the Xinjiang Uyghur Autonomous Region of Western China. Wirnan's seminal stegosaurian fossils thus expand current palaeobiogeographical distributions, and contribute to the otherwise enigmatic record of Early Cretaceous stegosaurian occurrences.

    Abstract [en]

    The ultrastructure of the sporangium, particularly the dehiscence apparatus in Pseudoperonospora humuli is similar to the one described in P. cubensis. This similarity is considered an indication of the homogeneity of the genus Pseudoperonospora. The dehiscence apparatus in P humuli is also similar to those occurring in other closely related, and even more

    distant genera of Oomycota. The importance of the poroid condition in distinguishing Pseudoperonospora

    from Peronospora is emphasised. The dehiscence apparatus is considered as the most appropriate term for the structures present in genera of Oomycota having poroid dissemination

    organs.

    Abstract [en]

    After a review of the taxonomy and nomenclature of Plasmopara, it is concluded that this genus contains at least two groups of fungi that can be differentiated on both morphological and molecular grounds. In order to avoid numerous nomenclatural changes, the genus Plasmoverna with seven new combinations (Pv. pygmaea, Pv. alpina, Pv. anemones-dichotomae, Pv. anemones-ranunculoides, Pv. fusca, Pv. hellebori, and Pv. isopyrithalictroides) is introduced to accommodate the species parasitic on Ranunculaceae, which have so far often been referred to as Plasmopara pygmaea s.l. The lectotypification of Plasmopara with Pl. pygmaea, which has been accepted by most authors in recent times, is shown to have been superseded by typification with Pl. nivea. To ensure nomenclatural stability, the ambiguous Pl. nivea is neotypified, and Plasmopara is retained in its current use for the bulk of the species.

The presence of two kinds of sporangia is due to the sporangiogenesis and considered to be present in all representatives of the Albuginales. Primary and secondary sporangia are the term recommended to be used for these dissemination organs.

    Abstract [en]

    Plasmopara halstedii (Farl.) Berl. & de Toni is among the most important species hampering commercial sunfl owerproduction in many countries. Downy mildew on Arctotheca and Arctotis collected in Australia and New Zealand has been attributedto Plasmopara halstedii, although it has never been reported on sunfl ower in those two countries. Potentially this makesit diffi cult for Australia and New Zealand to claim to be free of sunfl ower downy mildew; this has implications for quarantineand trade. Here we present morphological and molecular analyses of specimens of Plasmopara on Arctotis and Arctotheca collectedin Australia and New Zealand. Our results demonstrate that these plants are not attacked by Plasmopara halstedii but bya new species which we formally describe as Plasmopara majewskii sp. nov. in this study. Consequently, quarantine regulationsfor P. halstedii need to be enforced in order to protect the commercial sunfl ower industry in Australia and New Zealand.

    The earliest annelids: Lower Cambrian polychaetes from the Sirius Passet Lagerstätte, Peary Land, North Greenland2008Inngår i: Acta Palaeontologica Polonica, ISSN 0567-7920, E-ISSN 1732-2421, Vol. 53, nr 1, s. 137-148Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Apart from the Phyllopod Bed of the Burgess Shale (Middle Cambrian) polychaete annelids are practically unknown from any of the Cambrian Lagerstdtten. This is surprising both because their diversity in the Burgess Shale is considerable, while to date the Chengjiang Lagerstatte which is equally impressive in terms of faunal diversity has no reliable records of any annelids. Here we describe, on the basis of about 40 specimens, Phragmochaeta canicularis gen. et sp. nov. from the Lower Cambrian Sirius Passet Lagerstatte of Peary Land, North Greenland. This makes it by far the oldest known polychaete, with a likely age of lower to middle Atdabanian, The body consists of approximately 20 segments, each bearing notochaetae and neurochaetae. The former appeared to have formed a felt-like covering on the dorsum, whilst the neurochaetae projected obliquely to the longitudinal axis. Apart from minor differences in chaetal size at either end there is no other tagmosis. Details of the head are obscure, and presence of palps, tentacles and eyes are conjectural. Jaws appear to have been absent. The gut was straight, and flanked by massive longitudinal musculature. P. canicularis was evidently benthic, propelling itself on the neurochaetae, with the dorsal neurochaetae conferring protection. Its stratigraphic position and generalized appearance are consistent with P. canicularis being primitive, but the phylogenetic relationships within the polychaetes remain problematic, principally because of paucity of relevant morphological information.

    Climbing adaptations, locomotory disparity and ecological convergence in ancient stem 'kangaroos'2019Inngår i: Royal Society Open Science, E-ISSN 2054-5703, Vol. 6, nr 2, artikkel-id 181617Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Living kangaroos, wallabies and rat-kangaroos (Macropodoidea) constitute the most ecologically diverse radiation of Australasian marsupials. Indeed, even their hallmark bipedal hopping gait has been variously modified for bounding, walking and climbing. However, the origins of this locomotory adaptability are uncertain because skeletons of the most ancient macropodoids are exceptionally rare. Some of the stratigraphically oldest fossils have been attributed to Balbaridae-a clade of potentially quadrupedal stem macropodoids that became extinct during the late Miocene. Here we undertake the first assessment of balbarid locomotion using two-dimensional geometric morphometrics and a correlative multivariate analysis of linear measurements. We selected the astragalus and pedal digit IV ungual as proxies for primary gait because these elements are preserved in the only articulated balbarid skeleton, as well as some unusual early Miocene balbarid-like remains that resemble the bones of modern tree-kangaroos. Our results show that these fossils manifest character states indicative of contrasting locomotory capabilities. Furthermore, predictive modelling reveals similarities with extant macropodoids that employ either bipedal saltation and/or climbing. We interpret this as evidence for archetypal gait versatility, which probably integrated higher-speed hopping with slower-speed quadrupedal progression and varying degrees of scansoriality as independent specializations for life in forest and woodland settings.

Surveys of lichens and lichenicolous fungi have been taking place in the U.S. state of Alaska for more than 160 years, but until now assessing the full extent of their diversity has been hampered by the lack of a comprehensive and synonymized baseline inventory. In this paper we will begin to redress this by resolving outstanding nomenclatural issues and providing voucher data for a forthcoming catalog of Alaskan lichens, specifically: 1) synonymization,and/or resolution of status of species previously reported from Alaska, with emphasis on Alaskan types; 2) species new to the Alaska lichen biota; and 3) biogeographically significant new records from within Alaska. We report 91 species new to the flora of Alaska, including 65 lichens, three saprophytic calicioid fungi and 23 lichenicolous fungi. Of these, we report thirteen species, Biatora sphaeroidiza, Biatorella conspurcans, Chaenothecopsis arthoniae, Collemopsidium foveolatum, Dactylospora frigida, Halospora discrepans, Lecanora bryopsora, Opegrapha geographicola, Peltigera lyngei, Petractis clausa, Protoblastenia cyclospora, Thelocarpon impressellum and Usnea cylindrica as new to North America. In addition, Arthonia pruinata and Flavocetraria minuscula are new to Canada and Adelococcus alpestris new to the United States. We further place the following five names into synonymy: Lecania disceptans (Nyl.) Lynge [= Halecania alpivaga (Th.Fr.) M.Mayrhofer], Lecidea pallidella Nyl. [= Lecania subfuscula (Nyl.) S.Ekman], Lempholemma triptodes (Nyl.) Zahlbr. Leciophysma finmarkicum Th.Fr.), Polyblastia obtenta (Nyl.) Lynge [= Sporodictyon terrestre (Th.Fr.) S.Savic & Tibell], and Verrucaria pernigrata Nyl. [= Protothelenella sphinctrinoides (Nyl.) H.Mayrhofer & Poelt]. We propose restoring the long overlooked taxon Polyblastia exalbida (Nyl.) Zahlbr., currently known only from Alaska, to the North American lichen checklist. Finally, we propose the new combination Puttea caesia (Fr.) M.Svensson & T.Sprib. to replace Lecidea symmictella Nyl., which becomes a synonym.

    Macrostylocrinus bornholmensis Laursen, 1940, a forgotten Silurian crinoid from Denmark2019Inngår i: Proceedings Geological Association, ISSN 0016-7878, Vol. 130, nr 1, s. 76-80Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The monobathrid camerate crinoid Macrostylocrinus bornholmensis Laursen has an unfortunate history. It was published in a journal not commonly consulted by echinoderm workers and, worse, in time of war; written in a language not in common use for crinoid studies; and described by a stratigrapher, not an expert on pelmatozoans. These and other factors combined to ensure that M. bornholmensis has not been reassessed since it was first described almost 80 years ago, despite belonging to a genus well-known from the Lower Palaeozoic. Macrostylocrinus bornholmensis is Llandovery (Telychian) and not Wenlock as has been reported elsewhere. Diagnostic features include a column that does not bear radices close beneath the cup; a heteromorphic mesistele with five orders of regularly inserted internodals; three basal plates; smooth thecal plates with central folds following rays; and ten pinnulate free arms that are biserial distally. Macrostylocrinus bornholmensis is distinctly different in morphology from well-known, congeneric species described from the Lower Palaeozoic of northern Europe.

    The tergomyan Mollusc Carcassonnella from the Upper Ordovician of Girvan, Scotland2008Inngår i: Palaeontology, ISSN 0031-0239, E-ISSN 1475-4983, Vol. 51, nr Part 3, s. 663-675Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The tergomyan genus Carcassonnella Horny´ and Peel, 1996 is common in and characteristic of the Mediterranean Province in peri-Gondwanan terranes during the late Tremadoc and Arenig. It is united with other small, slitbearingcyrtonellids in the Carcassonnellidae Horny´ , 1997b, of which Baltiscanella Horny´ , 1997b from the Arenig of the Oslo Region, Norway, and Sarkanella from the Caradoc of the Siljan District, Sweden has been recognized outside the Mediterranean Province. The most inclusive view of the Carcassonnellidae unites Peelerophon Yochelson, 1982, Carcassonnella Horny´ and Peel, 1996, Sarkanella Horny´ , 1997a, Baltiscanella Horny´ , 1997b, and Tachillanella Horny´ , 1997b. Patterns of distribution of genera in the family are obscured, however, by widely different phylogenetic relationships presented in the literature. Here, Carcassonnella multilineata (Reed, 1920) is documented in the upper Whitehouse and Drummuck subgroups of the Girvan district, Midland Valley of Scotland, being the first record of the genus outside peri-Gondwana. Its enigmatic occurrence on the edge of Laurentia is opposed to the occurrence of low latitude benthic faunas in higher latitudes during this time interval (the Boda Event). It is likely, therefore, that the genus spread from the ancient stock found on the Perunican microcontinent as this drifted away from Gondwana in the mid-Caradoc.

    Ordovician (Caradoc) Gastropoda of the Katkoyeh Formation, Kerman Province, Iran2008Inngår i: Geobios, ISSN 0016-6995, E-ISSN 1777-5728, Vol. 41, nr 5, s. 605-624Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Seven taxa of gastropods are described from the Ordovician (Caradoc) upper Katkoyeh Formation of the Kerman region, east-central Iran.Three are named species and four are under open nomenclature. The most abundant is the minute bellerophontiform Tritonophon peeli Horny´,1977, indicative of a shallow water plectonotid community. Shell material is not preserved in this species, but a small, simple bulbous protoconch ispresent. Two new species are Slehoferia pachyta and Nonorios kleistos, both with prominent thick-shelled conchs. Shell repair is documented inboth of these forms, interpreted as a result of failed predation. Other micromorphic species occur in the samples, but only Tropidodiscus sp. andNonorios? sp. are named. The Kerman assemblage is comparable directly with similar, closely coeval faunas in Bohemia, France, Portugal,Morocco, and Italy, corresponding with the Palaeozoic Mediterranean Province of northern peri-Gondwana.
