New Permian Fauna from Tropical Gondwana
ARTICLE Received 18 Jun 2015 | Accepted 18 Sep 2015 | Published 5 Nov 2015 DOI: 10.1038/ncomms9676 OPEN New Permian fauna from tropical Gondwana Juan C. Cisneros1,2, Claudia Marsicano3, Kenneth D. Angielczyk4, Roger M. H. Smith5,6, Martha Richter7, Jo¨rg Fro¨bisch8,9, Christian F. Kammerer8 & Rudyard W. Sadleir4,10 Terrestrial vertebrates are first known to colonize high-latitude regions during the middle Permian (Guadalupian) about 270 million years ago, following the Pennsylvanian Gondwanan continental glaciation. However, despite over 150 years of study in these areas, the bio- geographic origins of these rich communities of land-dwelling vertebrates remain obscure. Here we report on a new early Permian continental tetrapod fauna from South America in tropical Western Gondwana that sheds new light on patterns of tetrapod distribution. Northeastern Brazil hosted an extensive lacustrine system inhabited by a unique community of temnospondyl amphibians and reptiles that considerably expand the known temporal and geographic ranges of key subgroups. Our findings demonstrate that tetrapod groups common in later Permian and Triassic temperate communities were already present in tropical Gondwana by the early Permian (Cisuralian). This new fauna constitutes a new biogeographic province with North American affinities and clearly demonstrates that tetrapod dispersal into Gondwana was already underway at the beginning of the Permian. 1 Centro de Cieˆncias da Natureza, Universidade Federal do Piauı´, 64049-550 Teresina, Brazil. 2 Programa de Po´s-Graduac¸a˜o em Geocieˆncias, Departamento de Geologia, Universidade Federal de Pernambuco, 50740-533 Recife, Brazil. 3 Departamento de Cs.

Stuttgart, 30. 12. 1999 Comparative osteology oi Mastodonsaurus giganteus (Jaeger, 1828) from the Middle Triassic (Lettenkeuper: Longobardian) of Germany (Baden-Württemberg, Bayern, Thüringen) By Rainer R. Schoch, Stuttgart With 4 plates and 54 textfigures Abstract Mastodonsaurus giganteus, the most abundant and giant amphibian of the German Letten- keuper, is revised. The study is based on the excellently preserved and very rieh material which was excavated during road construction in 1977 near Kupferzeil, Northern Baden- Württemberg. It is shown that there exists only one diagnosable species of Mastodonsaurus, to which all Lettenkeuper material can be attributed. All finds from other horizons must be referred to as Mastodonsauridae gen. et sp. indet. because of their fragmentary Status. A sec- ond, definitely diagnostic genus of this family is Heptasaurus from the higher Middle and Upper Buntsandstein. Finally a diagnosis of the family Mastodonsauridae is provided. Ä detailed osteological description of Mastodonsaurus giganteus reveals numerous un- known or formerly inadequately understood features, yielding data on various hitherto poor- ly known regions of the skeleton. The sutures of the skull roof, which could be studied in de- tail, are significantly different from the schemes presented by previous authors. The endocra- nium and mandible are further points of particular interest. The palatoquadrate contributes a significant part to the formation of the endocranium by an extensive and complicated epi- pterygoid. -

Schoch Staatliches Museum für Naturkunde, Rosenstein 1, D-70191 Stuttgart, Germany 〈[email protected]〉 Abstract.—Dissorophoid temnospondyls are widely considered to have given rise to some or all modern amphibians (Lissamphibia), but their ingroup relationships still bear major unresolved questions. An inclusive phylogenetic ana- lysis of dissorophoids gives new insights into the large-scale topology of relationships. Based on a TNT 1.5 analysis (33 taxa, 108 characters), the enigmatic taxon Perryella is found to nest just outside Dissorophoidea (phylogenetic defintion), but shares a range of synapomorphies with this clade. The dissorophoids proper are found to encompass a first dichotomy between the largely paedomorphic Micromelerpetidae and all other taxa (Xerodromes). Within the latter, there is a basal dichotomy between the large, heavily ossified Olsoniformes (Dissorophidae + Trematopidae) and the small salamander-like Amphibamiformes (new taxon), which include four clades: (1) Micropholidae (Tersomius, Pasawioops, Micropholis); (2) Amphibamidae sensu stricto (Doleserpeton, Amphibamus); (3) Branchiosaur- idae (Branchiosaurus, Apateon, Leptorophus, Schoenfelderpeton); and (4) Lissamphibia. The genera Platyrhinops and Eos- copus are here found to nest at the base of Amphibamiformes. Represented by their basal-most stem-taxa (Triadobatrachus, Karaurus, Eocaecilia), lissamphibians nest with Gerobatrachus rather than Amphibamidae, as repeatedly found by former analyses. -

An easy-to-navigate pocket guide to the Meeting is also available to delegates. Venue The Annual Meeting will take place in the faculties of Philosophy and Philology on the Blasco Ibañez Campus of the University of Valencia. The Symposium will take place in the Salon Actos Manuel Sanchis Guarner in the Faculty of Philology. The main meeting will take place in this and a nearby lecture theatre (Salon Actos, Faculty of Philosophy). There is a Metro stop just a few metres from the campus that connects with the centre of the city in 5-10 minutes (Line 3-Facultats). Alternatively, the campus is a 20-25 minute walk from the ‘old town’. Registration Registration will be possible before and during the Symposium at the entrance to the Salon Actos in the Faculty of Philosophy. During the main meeting the registration desk will continue to be available in the Faculty of Philosophy. Oral Presentations All speakers (apart from the symposium speakers) have been allocated 15 minutes. It is therefore expected that you prepare to speak for no more than 12 minutes to allow time for questions and switching between presenters. We have a number of parallel sessions in nearby lecture theatres so timing will be especially important. -

We have incorporated, where possible, original observations of numerous taxa spread throughout the major tetrapod clades. A stem-based (total-group) definition of Tetrapoda is preferred over apomorphy- and node-based (crown-group) definitions. This definition is operational, since it is based on a formal character analysis. A PAUP* search using a recently implemented version of the parsimony ratchet method yields 64 shortest trees. Differ- ences between these trees concern: (1) the internal relationships of aı¨stopods, the three selected species of which form a trichotomy; (2) the internal relationships of embolomeres, with Archeria -

Palaeontology in the virtual era BOOK OF ABSTRACTS 6 4 PRESENTATION The 1st Palaeontological Virtual Congress (1st PVC) is just the natural consequence of the evolution of our surrounding world, with the emergence of new technologies that allow a wide range of communication possibilities. Within this context, the 1st PVC represents the frst attempt in palaeontology to take advantage of these new possibilites being the frst international palaeontology congress developed in a virtual environment. This online congress is pioneer in palaeontology, offering an exclusively virtual-developed environment to researchers all around the globe. The simplicity of this new format, giving international projection to the palaeontological research carried out by groups with limited economic resources (expensive registration fees, travel, accomodation and maintenance expenses), is one of our main achievements. This new format combines the benefts of traditional meetings (i.e., providing a forum for discussion, including guest lectures, feld trips or the production of an abstract book) with the advantages of the online platforms, which allow to reach a high number of researchers along the world, promoting the participation of palaeontologists from developing countries. -
