Strophomenide and Orthotetide Silurian Brachiopods from the Baltic Region, with Particular Reference to Lithuanian Boreholes
Strophomenide and orthotetide Silurian brachiopods from the Baltic region, with particular reference to Lithuanian boreholes PETRAS MUSTEIKIS and L. ROBIN M. COCKS Musteikis, P. and Cocks, L.R.M. 2004. Strophomenide and orthotetide Silurian brachiopods from the Baltic region, with particular reference to Lithuanian boreholes. Acta Palaeontologica Polonica 49 (3): 455–482. Epeiric seas covered the east and west parts of the old craton of Baltica in the Silurian and brachiopods formed a major part of the benthic macrofauna throughout Silurian times (Llandovery to Pridoli). The orders Strophomenida and Orthotetida are conspicuous components of the brachiopod fauna, and thus the genera and species of the superfamilies Plec− tambonitoidea, Strophomenoidea, and Chilidiopsoidea, which occur in the Silurian of Baltica are reviewed and reidentified in turn, and their individual distributions are assessed within the numerous boreholes of the East Baltic, particularly Lithua− nia, and attributed to benthic assemblages. The commonest plectambonitoids are Eoplectodonta(Eoplectodonta)(6spe− cies), Leangella (2 species), and Jonesea (2 species); rarer forms include Aegiria and Eoplectodonta (Ygerodiscus), for which the new species E. (Y.) bella is erected from the Lithuanian Wenlock. Eight strophomenoid families occur; the rare Leptaenoideidae only in Gotland (Leptaenoidea, Liljevallia). Strophomenidae are represented by Katastrophomena (4 spe− cies), and Pentlandina (2 species); Bellimurina (Cyphomenoidea) is only from Oslo and Gotland. Rafinesquinidae include widespread Leptaena (at least 11 species) and Lepidoleptaena (2 species) with Scamnomena and Crassitestella known only from Gotland and Oslo. In the Amphistrophiidae Amphistrophia is widespread, and Eoamphistrophia, Eocymostrophia, and Mesodouvillina are rare. In the Leptostrophiidae Mesoleptostrophia, Brachyprion,andProtomegastrophia are com− mon, but Eomegastrophia, Eostropheodonta, Erinostrophia,andPalaeoleptostrophia are only recorded from the west in the Baltica Silurian. -
Constraints on the Timescale of Animal Evolutionary History
Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

Marsupials As Ancestors Or Sister Taxa?
Archives of natural history 39.2 (2012): 217–233 Edinburgh University Press DOI: 10.3366/anh.2012.0091 # The Society for the History of Natural History www.eupjournals.com/anh Darwin’s two competing phylogenetic trees: marsupials as ancestors or sister taxa? J. DAVID ARCHIBALD Department of Biology, San Diego State University, San Diego, CA 92182–4614, USA (e-mail: [email protected]). ABSTRACT: Studies of the origin and diversification of major groups of plants and animals are contentious topics in current evolutionary biology. This includes the study of the timing and relationships of the two major clades of extant mammals – marsupials and placentals. Molecular studies concerned with marsupial and placental origin and diversification can be at odds with the fossil record. Such studies are, however, not a recent phenomenon. Over 150 years ago Charles Darwin weighed two alternative views on the origin of marsupials and placentals. Less than a year after the publication of On the origin of species, Darwin outlined these in a letter to Charles Lyell dated 23 September 1860. The letter concluded with two competing phylogenetic diagrams. One showed marsupials as ancestral to both living marsupials and placentals, whereas the other showed a non-marsupial, non-placental as being ancestral to both living marsupials and placentals. These two diagrams are published here for the first time. These are the only such competing phylogenetic diagrams that Darwin is known to have produced. In addition to examining the question of mammalian origins in this letter and in other manuscript notes discussed here, Darwin confronted the broader issue as to whether major groups of animals had a single origin (monophyly) or were the result of “continuous creation” as advocated for some groups by Richard Owen. -
Phylogenetic Analysis of the Brachiopod Genus Leptaena Stephanie M
Family tree of a mass extinction survivor: Phylogenetic analysis of the brachiopod genus Leptaena Stephanie M. Plaza-Torres1, Simon A.F. Darroch2, Peter Wagner2 1University of Puerto Rico, Mayagüez Campus 2Department of Paleobiology, National Museum of Natural History, Smithsonian Institution Results Introduction Discussion Brachiopods are sessile, benthic invertebrates that occupy a wide range of water The weighted parsimony analysis of the species of Leptaena (Fig. 3) reconstructs two depths and are some of the most abundant organisms in the fossil record. Their abundance of the oldest Leptaena species (L. ventricosa [17] and L. infrunita [7]) as the most derived and diversity were their highest during the Paleozoic, having originated back in the species in the tree. Given the general improbability of these relationships, this likely reflects Cambrian, but there are still species that exist today[1]. Of all brachiopod genera, this study late members of a clade including L. delicata (4) through L. cooperi (3) converging upon focuses on Leptaena, a long ranging genus that extends from the Middle Ordovician through those taxa. There is good support for another clade including L. quadrata (11) through L. the Lower Devonian[3]. Leptaena is taxonomically diverse (it has over 50 named species)[3] gibbosa (6). This scenario is supported by very high early disparity (the typical anatomical and spans over two (the end-Ordovician and late-Devonian) of the ‘Big Five’ mass extinction difference among species; Fig. 9), which in turn suggests high early rates of change for events – making it a remarkable serial survivor of global biotic catastrophes. Moreover, Leptaena species. -

Few visitors are aware of the important paleontological resources that occur in the park. During the summer of 2016, a comprehensive field inventory of paleontological resources within CHIC was conducted. The inventory process involved primary literature research, an extensive field survey of fossiliferous units, and inventories of collections and repositories. The field survey yielded eight new fossiliferous localities, and eight previously undocumented taxa within CHIC. This is the first discovery of fossils in the Deese Group and Sycamore Limestone within the recreation area. During the 2016 inventory, fossils were documented at all previously known localities within CHIC, except for those localities now submerged under the Lake of the Arbuckles. Collections were made of the representative fauna found within CHIC, and 73 fossil specimens were accessioned into museum collections. -

Ordovician Rafinesquinine Brachiopods from Peri-Gondwana
Ordovician rafinesquinine brachiopods from peri-Gondwana JORGE COLMENAR Colmenar, J. 2016. Ordovician rafinesquinine brachiopods from peri-Gondwana. Acta Palaeontologica Polonica 61 (2): 293–326. The study of the strophomenide brachiopods of the subfamily Rafinesquininae present in the main Upper Ordovician sections, representing the Mediterranean margin of Gondwana, has revealed an increase in diversity of the group at the re- gion during that time. The studied collections are from the Moroccan Anti-Atlas, the Iberian and the Armorican massifs, the Iberian Chains, Pyrenees, Montagne Noire, Sardinia, and Bohemia. Two genera of the subfamily Rafinesquininae have been recorded. Of them, the cosmopolitan Rafinesquina is the only one previously reported from the region and Kjaerina is found for the first time outside Avalonia, Baltica, and Laurentia. Additionally, two new subgenera have been described, Kjaerina (Villasina) and Rafinesquina (Mesogeina). Furthermore, the new species Rafinesquina (Mesogeina) gabianensis, Rafinesquina (Mesogeina) loredensis, Kjaerina (Kjaerina) gondwanensis, Kjaerina (Villasina) pedro- naensis, Kjaerina (Villasina) pyrenaica, and Kjaerina (Villasina) meloui have been described. In addition, other spe- cies of these genera previously known from isolated localities in the region, such as Rafinesquina pseudoloricata, Rafinesquina pomoides, and Hedstroemina almadenensis are revised and their geographic range expanded. The adaptive radiation experienced by the rafinesquinines at the Mediterranean region during middle to late Katian, was probably related to changes in the regime of sedimentation and water temperature caused by the global warming Boda event. Key words: Strophomenoidea, palaeobiogeography, adaptive radiation, Ordovician, Katian, Boda event, Gondwana, Mediterranean region.
