  • A New Mid-Permian Burnetiamorph Therapsid from the Main Karoo Basin of South Africa and a Phylogenetic Review of Burnetiamorpha
    Editors' choice A new mid-Permian burnetiamorph therapsid from the Main Karoo Basin of South Africa and a phylogenetic review of Burnetiamorpha MICHAEL O. DAY, BRUCE S. RUBIDGE, and FERNANDO ABDALA Day, M.O., Rubidge, B.S., and Abdala, F. 2016. A new mid-Permian burnetiamorph therapsid from the Main Karoo Basin of South Africa and a phylogenetic review of Burnetiamorpha. Acta Palaeontologica Polonica 61 (4): 701–719. Discoveries of burnetiamorph therapsids in the last decade and a half have increased their known diversity but they remain a minor constituent of middle–late Permian tetrapod faunas. In the Main Karoo Basin of South Africa, from where the clade is traditionally best known, specimens have been reported from all of the Permian biozones except the Eodicynodon and Pristerognathus assemblage zones. Although the addition of new taxa has provided more evidence for burnetiamorph synapomorphies, phylogenetic hypotheses for the clade remain incongruent with their appearances in the stratigraphic column. Here we describe a new burnetiamorph specimen (BP/1/7098) from the Pristerognathus Assemblage Zone and review the phylogeny of the Burnetiamorpha through a comprehensive comparison of known material. Phylogenetic analysis suggests that BP/1/7098 is closely related to the Russian species Niuksenitia sukhonensis. Remarkably, the supposed mid-Permian burnetiids Bullacephalus and Pachydectes are not recovered as burnetiids and in most cases are not burnetiamorphs at all, instead representing an earlier-diverging clade of biarmosuchians that are characterised by their large size, dentigerous transverse process of the pterygoid and exclusion of the jugal from the lat- eral temporal fenestra. The evolution of pachyostosis therefore appears to have occurred independently in these genera.

  • A New Caenagnathid Dinosaur from the Upper Cretaceous Wangshi
    www.nature.com/scientificreports OPEN A new caenagnathid dinosaur from the Upper Cretaceous Wangshi Group of Shandong, China, with Received: 12 October 2017 Accepted: 7 March 2018 comments on size variation among Published: xx xx xxxx oviraptorosaurs Yilun Yu1, Kebai Wang2, Shuqing Chen2, Corwin Sullivan3,4, Shuo Wang 5,6, Peiye Wang2 & Xing Xu7 The bone-beds of the Upper Cretaceous Wangshi Group in Zhucheng, Shandong, China are rich in fossil remains of the gigantic hadrosaurid Shantungosaurus. Here we report a new oviraptorosaur, Anomalipes zhaoi gen. et sp. nov., based on a recently collected specimen comprising a partial left hindlimb from the Kugou Locality in Zhucheng. This specimen’s systematic position was assessed by three numerical cladistic analyses based on recently published theropod phylogenetic datasets, with the inclusion of several new characters. Anomalipes zhaoi difers from other known caenagnathids in having a unique combination of features: femoral head anteroposteriorly narrow and with signifcant posterior orientation; accessory trochanter low and confuent with lesser trochanter; lateral ridge present on femoral lateral surface; weak fourth trochanter present; metatarsal III with triangular proximal articular surface, prominent anterior fange near proximal end, highly asymmetrical hemicondyles, and longitudinal groove on distal articular surface; and ungual of pedal digit II with lateral collateral groove deeper and more dorsally located than medial groove. The holotype of Anomalipes zhaoi is smaller than is typical for Caenagnathidae but larger than is typical for the other major oviraptorosaurian subclade, Oviraptoridae. Size comparisons among oviraptorisaurians show that the Caenagnathidae vary much more widely in size than the Oviraptoridae. Oviraptorosauria is a clade of maniraptoran theropod dinosaurs characterized by a short, high skull, long neck and short tail.

    Rediscovery of the holotype of Clelandina major Broom, 1948 (Gorgonopsia: Rubidgeinae) with implications for the identity of this species Christian F. Kammerer North Carolina Museum of Natural Sciences, 11 W. Jones Street, Raleigh, North Carolina 27604, U.S.A., and Evolutionary Studies Institute, University of the Witwatersrand, Private Bag 3, WITS, Johannesburg, 2050 South Africa E-mail: [email protected] Received 7 November 2017. Accepted 8 December 2017 No specimen number was given for the holotype of the rubidgeine gorgonopsian species Clelandina major Broom, 1948 in its original description. Historically, a specimen in the Rubidge Collection (RC 94) was considered to represent Broom’s type specimen for C. major. However, recent study has revealed that the holotype of C. major is in fact a different specimen in the McGregor Museum in Kimberley (MMK 5031). The morphology of this specimen is consistent with the genus Clelandina, contra work based on RC 94 that considered C. major referable to Aelurognathus. Clelandina major is here considered synonymous with the type species Clelandina rubidgei. MMK 5031 represents only the fifth known specimen of this rare and unusual gorgonopsian.

The thickness of the formation exceeds 110 m. It is overlain by the Nemegt Formation (previously termed Upper Nemegt Beds), probably of Maast richtian age; the passage between the two format ions is gradual. A formal redefinition of the two Iithostra tigraphic divisions is presented in the paper. Five principal sediment types are distinguished in the Barun Goyot Formation, displaying sedimentary features indicative of various conditions of sedimentation. The lower part of the exposed profile of the Barun Goyot Formation is characterized by mega cross-stratified units, interpreted as dune deposits; they are intertonguing with water-deposited sediments laid in interdune areas. Chan nel deposits, attributed to intermittent streams are subordinate; massive sandstones, probably of various origin are predominating. The upper part of the profile of the formation is characterized by the predominance of flat-bedded sandstone units which were probabl y deposited in an intermittently flooded takyr-like area.

  • Physical and Environmental Drivers of Paleozoic Tetrapod Dispersal Across Pangaea
    ARTICLE https://doi.org/10.1038/s41467-018-07623-x OPEN Physical and environmental drivers of Paleozoic tetrapod dispersal across Pangaea Neil Brocklehurst1,2, Emma M. Dunne3, Daniel D. Cashmore3 &Jӧrg Frӧbisch2,4 The Carboniferous and Permian were crucial intervals in the establishment of terrestrial ecosystems, which occurred alongside substantial environmental and climate changes throughout the globe, as well as the final assembly of the supercontinent of Pangaea. The fl 1234567890():,; in uence of these changes on tetrapod biogeography is highly contentious, with some authors suggesting a cosmopolitan fauna resulting from a lack of barriers, and some iden- tifying provincialism. Here we carry out a detailed historical biogeographic analysis of late Paleozoic tetrapods to study the patterns of dispersal and vicariance. A likelihood-based approach to infer ancestral areas is combined with stochastic mapping to assess rates of vicariance and dispersal. Both the late Carboniferous and the end-Guadalupian are char- acterised by a decrease in dispersal and a vicariance peak in amniotes and amphibians. The first of these shifts is attributed to orogenic activity, the second to increasing climate heterogeneity. 1 Department of Earth Sciences, University of Oxford, South Parks Road, Oxford OX1 3AN, UK. 2 Museum für Naturkunde, Leibniz-Institut für Evolutions- und Biodiversitätsforschung, Invalidenstraße 43, 10115 Berlin, Germany. 3 School of Geography, Earth and Environmental Sciences, University of Birmingham, Birmingham B15 2TT, UK. 4 Institut

Using associated depositional environment and taxonomic information, the vertebrate database was limited to only terrestrial organisms, excluding amphibians, pseudosuchians, champsosaurs and ichnotaxa. Taxa present in formations were confirmed against the most recent available literature, as of November, 2020. Synonymous taxa or otherwise duplicated taxa were removed. Taxa that could not be identified to genus level 35 were included as “Taxon X”. GPS locality data for all formations between 200MA and 65MA was downloaded from PaleoDB to create a minimally convex polygon for each possible formation. Any attempt to recreate local assemblages must include all potentially interacting species, while excluding those that would have been separated by either space or time. We argue it is 40 acceptable to substitute formation for home range in the case of non-avian dinosaurs, as range increases with body size.
