Edaphosaurus Boanerges Edaphosaurus Was a Large Synapsid That Time: 250-300 Million Lived in North America and Europe 300 Years Ago Million Years Ago

Crazy Creatures Edaphosaurus boanerges Edaphosaurus was a large synapsid that Time: 250-300 million lived in North America and Europe 300 years ago million years ago. Period: Carboniferous Edaphosaurus looked similar to a much and Permian more famous creature but was very different, with a tiny head and huge, The Sail-Backed unique teeth. Herbivore It had a huge sail on its back that remains a bit of a mystery to this day! Your task 1: Draw Edaphosaurus. It had: A small, square head A wide, thick body A large semicircle sail on its back Sprawling legs with big claws Your task 2: Edaphosaurus sail was made from skin stretched between spines of bone. There are lots of reasons an animal might have a big sail like this one. What do you think Edaphosaurus used its sail for? Creature Fact! Your task 3: Edaphosaurus looks similar to another famous creature. Do some Edaphosaurus research to find out which one! means “pavement lizard” it is named after its unusual teeth! Your task 4: Edaphosaurus had many smaller pointy teeth and two giant teeth almost as big as its entire mouth! Why do you think it had such big teeth? Your task 5: Edaphosaurus might have used its sail to show off! That means it would have really bright colours. Colour in the sail below with the colours you think it had! Your task 6: Edaphosaurus had a huge body and a tiny head. Lots of animals that eat plants have big bodies and small heads so they can fit in lots of stomach to digest their food. Can you name four other animals that have a very small head and a big body? 1. 2. 3. 4. Research key words: Synapsid Dimetrodon thermoregulation CRAZYOMETER! How weird do you think this creature was?

Morphology, Phylogeny, and Evolution of Diadectidae (Cotylosauria: Diadectomorpha)
Morphology, Phylogeny, and Evolution of Diadectidae (Cotylosauria: Diadectomorpha) by Richard Kissel A thesis submitted in conformity with the requirements for the degree of doctor of philosophy Graduate Department of Ecology & Evolutionary Biology University of Toronto © Copyright by Richard Kissel 2010 Morphology, Phylogeny, and Evolution of Diadectidae (Cotylosauria: Diadectomorpha) Richard Kissel Doctor of Philosophy Graduate Department of Ecology & Evolutionary Biology University of Toronto 2010 Abstract Based on dental, cranial, and postcranial anatomy, members of the Permo-Carboniferous clade Diadectidae are generally regarded as the earliest tetrapods capable of processing high-fiber plant material; presented here is a review of diadectid morphology, phylogeny, taxonomy, and paleozoogeography. Phylogenetic analyses support the monophyly of Diadectidae within Diadectomorpha, the sister-group to Amniota, with Limnoscelis as the sister-taxon to Tseajaia + Diadectidae. Analysis of diadectid interrelationships of all known taxa for which adequate specimens and information are known—the first of its kind conducted—positions Ambedus pusillus as the sister-taxon to all other forms, with Diadectes sanmiguelensis, Orobates pabsti, Desmatodon hesperis, Diadectes absitus, and (Diadectes sideropelicus + Diadectes tenuitectes + Diasparactus zenos) representing progressively more derived taxa in a series of nested clades. In light of these results, it is recommended herein that the species Diadectes sanmiguelensis be referred to the new genus

Our approach differs from the previous ones in that it takes into account the possibility that the taxa or the clade considered may diversify before going extinct, whilst previous methods just rely on the fossil recovery rate to estimate confidence intervals. We assess and compare our new approach with a standard previous one using simulated data. Results show that our method provides more accurate confidence intervals. This new approach is applied to the study of the extinction time of three Permo-Carboniferous synapsid taxa (Ophiacodontidae, Edaphosauridae, and Sphenacodontidae) that are thought to have disappeared toward the end of the Cisuralian, or possibly shortly thereafter. The timing of extinctions of these three taxa and of their component lineages supports the idea that a biological crisis occurred in the late Kungurian/early Roadian.

Morphology and Evolutionary Significance of the Atlas−Axis Complex in Varanopid Synapsids
Morphology and evolutionary significance of the atlas−axis complex in varanopid synapsids NICOLÁS E. CAMPIONE and ROBERT R. REISZ Campione, N.E. and Reisz, R.R. 2011. Morphology and evolutionary significance of the atlas−axis complex in varanopid synapsids. Acta Palaeontologica Polonica 56 (4): 739–748. The atlas−axis complex has been described in few Palaeozoic taxa, with little effort being placed on examining variation of this structure within a small clade. Most varanopids, members of a clade of gracile synapsid predators, have well pre− served atlas−axes permitting detailed descriptions and examination of morphological variation. This study indicates that the size of the transverse processes on the axis and the shape of the axial neural spine vary among members of this clade. In particular, the small mycterosaurine varanopids possess small transverse processes that point posteroventrally, and the axial spine is dorsoventrally short, with a flattened dorsal margin in lateral view. The larger varanodontine varanopids have large transverse processes with a broad base, and a much taller axial spine with a rounded dorsal margin in lateral view. Based on outgroup comparisons, the morphology exhibited by the transverse processes is interpreted as derived in varanodontines, whereas the morphology of the axial spine is derived in mycterosaurines. The axial spine anatomy of Middle Permian South African varanopids is reviewed and our interpretation is consistent with the hypothesis that at least two varanopid taxa are present in South Africa, a region overwhelmingly dominated by therapsid synapsids and parareptiles. Key words: Synapsida, Varanopidae, Mycterosaurinae, Varanodontinae, atlas−axis complex, axial skeleton, Middle Permian, South Africa.

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

A New Basal Sphenacodontid Synapsid from the Late Carboniferous of the Saar−Nahe Basin, Germany
A new basal sphenacodontid synapsid from the Late Carboniferous of the Saar−Nahe Basin, Germany JÖRG FRÖBISCH, RAINER R. SCHOCH, JOHANNES MÜLLER, THOMAS SCHINDLER, and DIETER SCHWEISS Fröbisch, J., Schoch, R.R., Müller, J., Schindler, T., and Schweiss, D. 2011. A new basal sphenacodontid synapsid from the Late Carboniferous of the Saar−Nahe Basin, Germany. Acta Palaeontologica Polonica 56 (1): 113–120. A new basal sphenacodontid synapsid, represented by an anterior portion of a mandible, demonstrates for the first time the presence of amniotes in the largest European Permo−Carboniferous basin, the Saar−Nahe Basin. The new taxon, Cryptovenator hirschbergeri gen. et sp. nov., is autapomorphic in the extreme shortness and robustness of the lower jaw, with moderate heterodonty, including the absence of a greatly reduced first tooth and only a slight caniniform develop− ment of the second and third teeth. Cryptovenator shares with Dimetrodon, Sphenacodon, and Ctenospondylus, but nota− bly not with Secodontosaurus, enlarged canines and a characteristic teardrop outline of the marginal teeth in lateral view, possession of a deep symphyseal region, and a strongly concave dorsal margin of the dentary. The new find shows that sphenacodontids were present in the Saar−Nahe Basin by the latest Carboniferous, predating the record of sphenacodontid tracks from slightly younger sediments in this region. Key words: Synapsida, Sphenacodontidae, Carboniferous, Saar−Nahe Basin, Germany.

First Canadian 'Dinosaur' Becomes Dimetrodon Borealis 24 November 2015, by Nicolle Wahl
Canuckosaur! First Canadian 'dinosaur' becomes Dimetrodon borealis 24 November 2015, by Nicolle Wahl says lead author Kirstin Brink, who did the research while at UTM. "Dimetrodon is actually more closely related to mammals than it is to dinosaurs." In fact, it's believed they went extinct some 40 million years before the dinosaurs. The study appears in the November 23 issue of the Canadian Journal of Earth Sciences. The fossil, previously known at Bathygnathus borealis, was collected in 1845 while a farmer was digging out a well on his property near French River, PEI. As there were no natural history museums in Canada at the time the fossil was found, it was sold to the Academy of Natural Sciences in Philadelphia, where Joseph Leidy—a preeminent paleontologist—could study and name it. Leidy named the fossil Bathygnathus (meaning deep jaw) borealis (from the north) because he mistook it as the lower jaw of a dinosaur, similar to the large bipedal species that were being collected in Europe at the time. The Bathygnathus specimen was the first "dinosaur", and the second vertebrate fossil named Dimetrodon is shown with an overlay of the from Canada (Dendrerpeton, an extinct amphibian "Bathygnathus" fossil from PEI, with a Walchia tree in from Nova Scotia, was named by Sir Richard Owen the background (a common fossil found on PEI). Credit: two months earlier). Several paleontologists have Danielle Dufault studied the Bathygnathus specimen since it was first named, but its precise identity was unknown. For example, it was unclear whether it had Dimetrodon's signature dorsal sail—created by A "dinosaur" fossil originally discovered on Prince tissue stretched between spines sticking up from its Edward Island has been shown to have steak knife- backbone—or lacked a sail like its smaller cousin like teeth, and researchers from U of T Sphenacodon.

As initially designated in 2016, BENM encompassed 1.3 million acres of land with exceptionally fossiliferous rock units. Subsequently, in December 2017, presidential action reduced BENM to two smaller management units (Indian Creek and Shash Jáá). Although the paleontological resources of BENM are extensive and abundant, they have historically been under-studied. Here, we summarize prior paleontological work within the original BENM boundaries in order to provide a complete picture of the paleontological resources, and synthesize the data which were used to support paleontological resource protection.

Callibrachion and Datheosaurus, Two Historical and Previously Mistaken Basal Caseasaurian Synapsids from Europe
Callibrachion and Datheosaurus, two historical and previously mistaken basal caseasaurian synapsids from Europe FREDERIK SPINDLER, JOCELYN FALCONNET, and JÖRG FRÖBISCH Spindler, F., Falconnet, J., and Fröbisch, J. 2016. Callibrachion and Datheosaurus, two historical and previously mis- taken basal caseasaurian synapsids from Europe. Acta Palaeontologica Polonica 61 (3): 597–616. This study represents a re-investigation of two historical fossil discoveries, Callibrachion gaudryi (Artinskian of France) and Datheosaurus macrourus (Gzhelian of Poland), that were originally classified as haptodontine-grade sphenaco- dontians and have been lately treated as nomina dubia. Both taxa are here identified as basal caseasaurs based on their overall proportions as well as dental and osteological characteristics that differentiate them from any other major syn- apsid subclade. As a result of poor preservation, no distinct autapomorphies can be recognized. However, our detailed investigations of the virtually complete skeletons in the light of recent progress in basal synapsid research allow a novel interpretation of their phylogenetic positions. Datheosaurus might represent an eothyridid or basal caseid. Callibrachion shares some similarities with the more derived North American genus Casea. These new observations on Datheosaurus and Callibrachion provide new insights into the early diversification of caseasaurs, reflecting an evolutionary stage that lacks spatulate teeth and broadened phalanges that are typical for other caseid species. Along with Eocasea, the former ghost lineage to the Late Pennsylvanian origin of Caseasauria is further closed. For the first time, the presence of basal caseasaurs in Europe is documented. Key words: Synapsida, Caseasauria, Carboniferous, Permian, Autun Basin, France, Intra-Sudetic Basin, Poland.
