Robyn Lee Burrows Ursula Walther Biography & Facts

Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2019. Flora Plants Fungi Paleomycological research Fossil sporocarps indistinguishable from sporocarps of members of the extant genus Stemonitis are described from the Cretaceous amber from Myanmar by Rikkinen, Grimaldi & Schmidt (2019). A study on the impact of major historical events such as the Cretaceous–Paleogene extinction event on the evolution of two major subclasses of lichen-forming fungi (Lecanoromycetidae and Ostropomycetidae) is published by Huang et al. (2019). Description of crustose lichens from European Paleogene amber is published by Kaasalainen et al. (2019). Fungi belonging to the genera Periconia, Penicillium and Scopulariopsis, representing the first and the oldest known fossil record of these taxa, are described from the Eocene Baltic amber by Tischer et al. (2019). Sponges Research Sponge spicules and spicule-like structures that probably represent sponge fossils are described from four sections of the Ediacaran-Cambrian boundary interval in the Yangtze Gorges (China) by Chang et al. (2019). A study evaluating how distribution patterns of non-lithistid spiculate sponges changed during the Cambrian explosion and the Great Ordovician Biodiversification Event is published by Botting & Muir (2019). New taxa Cnidarians Research A study on the growth characteristics of three species of Ordovician corals belonging to the genus Agetolites from the Xiazhen Formation (China), and on their implications for inferring phylogenetic relationships of this genus, is published by Sun, Elias & Lee (2019). A study on a large colonial rugose coral from the Ordovician Kope Formation (Kentucky, United States) is published by Harris et al. (2019). A study on the morphology, growth characteristics and phylogenetic relationships of the Silurian tabulate coral Halysites catenularius is published by Liang, Elias & Lee (2019). Fossils of tabulate corals without septa, representing the first evidence that unmetamorphosed, slightly indurated Paleozoic sandstones crop out amidst the deposits of the Atlantic Coastal Plain Province of the United States, are reported from South Carolina by Landmeyer et al. (2019). This finding is strongly disputed because all other rocks of Paleozoic age in the study area are greatly metamorphosed, the rocks where the fossils were found are traditionally mapped as the Cretaceous Middendorf Formation, and it is suggested that the fossils in question are the bark of Cretaceous conifers in Cretaceous sandstone, instead of Paleozoic corals in Paleozoic sandstone. A study aiming to determine whether ecological selection based on physiology, behavior, habitat, etc. played a role in the long-term survival of corals during the late Paleocene and early Eocene is published by Weiss & Martindale (2019). Fossils of Acropora prolifera dating back to the Pleistocene are reported by Precht et al. (2019). A study on the distribution of reef corals during the last interglacial is published by Jones et al. (2019), who also evaluate the utility of fossil reef coral data for predictions of impact of future climate changes on reef corals. A study on a problematic fossil specimen from the Devonian Ponta Grossa Formation (Brazil), assigned by different authors to the species Serpulites sica or Euzebiola clarkei, is published by Van Iten et al. (2019), who interpret this fossil as a medusozoan capable of clonal budding, and transfer it to the genus Sphenothallus. The oldest mesophotic coral ecosystems, dating back to middle Silurian, from the Lower Visby Beds on Gotland have been described by Zapalski & Berkowski. These communities, dominated by platy corals give also clues about the onset of coral-algal symbiosis. Mihaljević (2019) describes new fossil coral collections from the Oligocene and Miocene of Sarawak (Malaysia), Negros Island and Cebu (the Philippines). A study on the anatomy, ontogeny and taxonomy of the Norian hydrozoan Heterastridium, based on data from fossil specimens from central Iran and south Turkey, is published by Senowbari-Daryan & Link (2019). New taxa Arthropods Bryozoans Brachiopods Molluscs Echinoderms Research A study on the morphology and phylogenetic relationships of the putative stem-echinoderm Yanjiahella biscarpa is published by Topper et al. (2019); the study is subsequently criticized by Zamora et al. (2020). Soft tissue traces found in conjunction with skeletal molds are described in stylophorans by Lefebvre et al. (2019), who interpret their findings as supporting echinoderm and not hemichordate-like affinities of stylophorans. A study on the morphology and phylogenetic relationships of the lepidocystoid echinoderm Vyscystis is published by Nohejlová et al. (2019). A study on the phylogenetic relationships of diploporitan blastozoans is published by Sheffield & Sumrall (2019). A study on the morphology of the feeding ambulacral system in the Ordovician diploporitan Eumorphocystis, as indicated by data from well-preserved specimens from the Bromide Formation (Oklahoma, United States), is published by Sheffield & Sumrall (2019), who interpret their findings as indicating that Eumorphocystis was closely related to crinoids and that crinoids are nested within blastozoans; their conclusions about the relationship between Eumorphocystis and crinoids are subsequently contested by Guensburg et al. (2020). A study on the morphology and phylogenetic relationships of Macurdablastus uniplicatus is published by Bauer, Waters & Sumrall (2019). A study on the morphology and phylogenetic relationships of Hexedriocystis is published online by Zamora & Sumrall (2019), who consider this taxon to be a blastozoan. A study on the paleoecology of the specimens of the edrioasteroid Neoisorophusella lanei preserved in limestone slabs from the Carboniferous (Chesterian) Kinkaid Formation (Illinois, United States) is published by Shroat-Lewis, Greenwood & Sumrall (2019). A study on the morphology of Cupulocrinus and on its implications for inferring the origin of the flexible crinoids is published by Peter (2019). A study on the phylogenetic relationships of diplobathrid crinoids is published by Cole (2019). A study on the biological and ecological controls on duration of diplobathrid crinoid genera is published online by Cole (2019). A study on the macro-evolutionary patterns of body-size trends of cyrtocrinid crinoids is published by Brom (2019). A study on pa.... Discover the Robyn Lee Burrows Ursula Walther popular books.
