Smith3 1Department of Earth Sciences, University of Bristol, Wills Memorial Building, Queens Road, BS8 1RJ, United Kingdom 2Department of Biology, University of Toronto at Mississauga, 3359 Mississauga Rd., Mississauga, ON, L5L 1C6, Canada 3Divison of Earth Sciences, South African Museum, P.O. Box 61, Cape Town, 8000 South Africa Received 19 May 2005. Accepted 8 June 2006 The dicynodont specimen SAM-PK-708 has been referred to the genera Pristerodon and Emydops by various authors, and was used to argue that the first appearance of Emydops was in the Tapinocephalus Assemblage Zone in the Karoo Basin of South Africa. However, the specimen never has been described in detail, and most discussions of its taxonomic affinities were based on limited data. Here we redescribe the specimen and compare it to several small dicynodont taxa from the Tapinocephalus and Pristerognathus assemblage zones. Although the specimen is poorly preserved, it possesses a unique combination of features that allows it to be assigned confidently to Emydops. The locality data associated with SAM-PK-708 are vague, but they allow the provenance of the specimen to be narrowed down to a relatively limited area southwest of the town of Beaufort West. Strata from the upper Tapinocephalus Assemblage Zone and the Pristerognathus Assemblage Zone crop out in this area, but we cannot state with certainty from which of these biostratigraphic divisions the specimen was collected.

These three Late Jurassic areas, dated as Kimmeridgian to Tithonian are similar paleoenvironmentally and faunally. Four dinosaur genera are shared between Portugal and the Morrison (Allosaurus, Torvosaurus, Ceratosaurus and Apatosaurus), as well as all non-avian dinosaur families. Episodic dis- persal occurred until at least the Late Jurassic. The Portuguese dinosaurs did not developed dwarfism and are as large as Morrison and Tendaguru dinosaurs. Resumo em português—São comparadas as Formações de Lourinhã e Alcobaça (em Portugal), Formação de Morrison (na América do Norte) e as Tendaguru Beds (na Tanzânia). Estas três áreas do Jurássico Superior (Kimmeridgiano/ Titoniano) têm muitas semelhanças relativamente aos paleoambientes. Quatro géneros de dinossauros são comuns a Portugal e Morrison (Allosaurus, Torvosaurus, Ceratosaurus e Apatosaurus), assim como todas as famílias de dinossauros não-avianos. Episódios migratórios ocorreram pelo menos até ao Jurássico Superior. Os dinossauros de Portugal não desenvolveram nanismo e eram tão grandes como os dinossauros de Morrison e Tendaguru.

ACKNOWLEDGMENTS First of all, I would like to dedicate this thesis to my late grandfather “Papi Joël”, who wanted to tie me to a tree when I first start my journey to paleontology six years ago, in Paris. And yet, he never failed to support me at any cost, even if he did not always understand what I was doing and why I was doing it. He is always in my mind. Merci papi ! This master thesis has been one-year long project during which one there were highs and lows.

  • 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

  • The Many Faces of Synapsid Cranial Allometry
    Paleobiology, 45(4), 2019, pp. 531–545 DOI: 10.1017/pab.2019.26 Article The many faces of synapsid cranial allometry Isaac W. Krone , Christian F. Kammerer, and Kenneth D. Angielczyk Abstract.—Previous studies of cranial shape have established a consistent interspecific allometric pattern relating the relative lengths of the face and braincase regions of the skull within multiple families of mam- mals. In this interspecific allometry, the facial region of the skull is proportionally longer than the braincase in larger species. The regularity and broad taxonomic occurrence of this allometric pattern suggests that it may have an origin near the base of crown Mammalia, or even deeper in the synapsid or amniote forerun- ners of mammals. To investigate the possible origins of this allometric pattern, we used geometric morpho- metric techniques to analyze cranial shape in 194 species of nonmammalian synapsids, which constitute a set of successive outgroups to Mammalia. We recovered a much greater diversity of allometric patterns within nonmammalian synapsids than has been observed in mammals, including several instances similar to the mammalian pattern. However, we found no evidence of the mammalian pattern within Theroce- phalia and nonmammalian Cynodontia, the synapsids most closely related to mammals. This suggests that the mammalian allometric pattern arose somewhere within Mammaliaformes, rather than within nonmammalian synapsids. Further investigation using an ontogenetic series of the anomodont Diictodon feliceps shows that the pattern of interspecific allometry within anomodonts parallels the ontogenetic trajectory of Diictodon. This indicates that in at least some synapsids, allometric patterns associated with ontogeny may provide a “path of least resistance” for interspecific variation, a mechanism that we suggest produces the interspecific allometric pattern observed in mammals.

  • A New Docodont Mammal from the Late Jurassic of the Junggar Basin in Northwest China
    A new docodont mammal from the Late Jurassic of the Junggar Basin in Northwest China HANS−ULRICH PFRETZSCHNER, THOMAS MARTIN, MICHAEL W. MAISCH, ANDREAS T. MATZKE, and GE SUN Pfretzschner, H.−U., Martin, T., Maisch, M.W., Matzke, A.T., and Sun, G. 2005. A new docodont mammal from the Late Jurassic of the Junggar Basin in Northwest China. Acta Palaeontologica Polonica 50 (4): 799–808. Fieldwork in the early Late Jurassic (Oxfordian) Qigu Formation of the Junggar Basin in Northwest China (Xinjiang Au− tonomous Region) produced teeth and mandibular fragments of a new docodont. The new taxon has a large “pseudo− talonid” on the lower molars, and by retention of crest b−g exhibits closer affinities to Simpsonodon and Krusatodon from the Middle Jurassic of Europe than to the other known Asian docodonts Tashkumyrodon, Tegotherium,andSibirotherium. It differs from the Haldanodon–Docodon−lineage by the “pseudotalonid” and large cusps b and g. A PAUP analysis based on lower molar characters produced a single most parsimonious tree with two main clades. One clade comprises Docodon, Haldanodon, and Borealestes, and the other Dsungarodon, Simpsonodon, and Krusatodon plus the Asian tegotheriids. Analysis of the molar occlusal relationships using epoxy casts mounted on a micromanipulator revealed a four−phase chewing cycle with transverse component. The molars of the new docodont exhibit a well developed grinding function be− sides cutting and shearing, probably indicating an omnivorous or even herbivorous diet. A grinding and crushing function is also present in the molars of Simpsonodon, Krusatodon, and the Asian tegotheriids, whereas Borealestes, Haldanodon, and Docodon retain the plesiomorphic molar pattern with mainly piercing and cutting function.

  • Mosaic Mine Hunt!!!
    FOSSIL CLUB OF LEE COUNTY AUGUST 2015 Letter from the President Well, fellow fossilnerds, here we are!! Hot, sticky, rainy summer and no place to fossil hunt! The summer doldrums are here! Our rivers and creeks are over our heads and unless you're a diver and going to Venice, you better have a land site if you want to fossil hunt. So, I guess this is as good a time as any to take a vacation, which lots of you guys are doing. Last month we had a rather low attendance at the meeting, since so many folks are not around. Those faithful members who attended the July meeting were able to enjoy themselves digging through lots of fossil matrix gravel, and finding small fossils. Michael Gessel was kind enough to provide the sieved, washed gravel to us, before he returned to his summer place in New York. And, we thank Michael a whole lot for his kindness and generosity. There is not much happening right now in the local fossil scene. However, a couple of members went to the FOSSIL Project workshop in Gainesville to study digital fossil photography and 3d printing. An article is inside this newsletter. Mosaic has awarded us a date to hunt their phosphate mine, October 10. Please come to the meeting to sign up to go. Since it is off season, we should not have to do a lottery to pick spots, but I suggest to attend a meeting and sign up while there is still space available. In-person signup will take precedence over call-ins.
