A New Sebecid Mesoeucrocodylian from the Rio Loro Formation (Palaeocene) of North-Western Argentina
Zoological Journal of the Linnean Society, 2011, 163, S7–S36. With 17 figures A new sebecid mesoeucrocodylian from the Rio Loro Formation (Palaeocene) of north-western Argentina DIEGO POL1* and JAIME E. POWELL2 1CONICET, Museo Paleontológico Egidio Feruglio, Ave. Fontana 140, Trelew CP 9100, Chubut, Argentina 2CONICET, Instituto Miguel Lillo, Miguel Lillio 205, San Miguel de Tucumán CP 4000, Tucumán, Argentina Received 2 March 2010; revised 10 October 2010; accepted for publication 19 October 2010 A new basal mesoeucrocodylian, Lorosuchus nodosus gen. et sp. nov., from the Palaeocene of north-western Argentina is presented here. The new taxon is diagnosed by the presence of external nares facing dorsally, completely septated, and retracted posteriorly, elevated narial rim, sagittal crest on the anteromedial margins of both premaxillae, dorsal crests and protuberances on the anterior half of the rostrum, and anterior-most three maxillary teeth with emarginated alveolar margins. This taxon is most parsimoniously interpreted as a bizarre and highly autapomorphic basal member of Sebecidae, a position supported (amongst other characters) by the elongated bar-like pterygoid flanges, a laterally opened notch and fossa in the pterygoids located posterolaterally to the choanal opening (parachoanal fossa), base of postorbital process of jugal directed dorsally, and palatal parts of the premaxillae meeting posteriorly to the incisive foramen. Lorosuchus nodosus also shares with basal neosuchians a suite of derived characters that are interpreted as convergently acquired and possibly related to their semiaquatic lifestyle. The phylogenetic analysis used for testing the phylogenetic affinities of L. nodosus depicts Sebecidae as the sister group of Baurusuchidae, forming a monophyletic Sebecosuchia that is deeply nested within Notosuchia. -

Athos da Silveira Ramos, 244, Zip Code 21.949-900, Cidade Universitária - Ilha do Fundão. Rio de Janeiro - RJ. Brazil; e-mail: [email protected]; [email protected] Abstract—The body fossil and ichnological fossil record associated with Baurusuchus salgadoensis (Baurusuchidae: Mesoeucrocodylia) in General Salgado County (Adamantina Formation, Bauru Basin, Brazil) is diverse and outstanding with regard to preservation and completeness. Invertebrate ichnofossils, fossil eggs, coprolites, gas- troliths and tooth marks on Baurusuchus fossils have been identified. The seasonal climate developed in the Bauru Basin during the Late Cretaceous created stressful conditions forcing animals to endure aridity and food scarcity. The Baurusuchidae underwent long arid seasons, probably resorting to intraspecific fighting, scavenging, self- burrowing mounds and stone ingestion. The integration of sedimentology, ichnology and taphonomic data is useful to reconstruct in detail the ecological scenarios under which Late Cretaceous Crocodyliformes survived.

Two species are known from the Neuquén Group in Argentina: Lomasuchus palpebrosus (Portezuelo Formation, late Turonian–early Coniacian) and Gasparinisuchus peirosauroides (Bajo de la Carpa and Anacleto formations, Santonian and early Campanian, respectively). Here, we describe the first peirosaurid from the Cerro Lisandro Formation, Bayomesasuchus hernandezi gen. et sp. nov. The material corresponds to a fragmentary skull and mandible. Although frag - mentary, this is the most complete crocodyliform specimen recorded for the Cerro Lisandro Formation.

From the Late Cretaceous of Brazil and the Phylogeny of Baurusuchidae
A New Baurusuchid (Crocodyliformes, Mesoeucrocodylia) from the Late Cretaceous of Brazil and the Phylogeny of Baurusuchidae Felipe C. Montefeltro1*, Hans C. E. Larsson2, Max C. Langer1 1 Departamento de Biologia, Faculdade de Filosofia, Cieˆncias e Letras de Ribeira˜o Preto – Universidade de Sa˜o Paulo, Ribeira˜o Preto, Brazil, 2 Redpath Museum, McGill University, Montre´al, Canada Abstract Background: Baurusuchidae is a group of extinct Crocodyliformes with peculiar, dog-faced skulls, hypertrophied canines, and terrestrial, cursorial limb morphologies. Their importance for crocodyliform evolution and biogeography is widely recognized, and many new taxa have been recently described. In most phylogenetic analyses of Mesoeucrocodylia, the entire clade is represented only by Baurusuchus pachecoi, and no work has attempted to study the internal relationships of the group or diagnose the clade and its members. Methodology/Principal Findings: Based on a nearly complete skull and a referred partial skull and lower jaw, we describe a new baurusuchid from the Vale do Rio do Peixe Formation (Bauru Group), Late Cretaceous of Brazil. The taxon is diagnosed by a suite of characters that include: four maxillary teeth, supratemporal fenestra with equally developed medial and anterior rims, four laterally visible quadrate fenestrae, lateral Eustachian foramina larger than medial Eustachian foramen, deep depression on the dorsal surface of pterygoid wing. The new taxon was compared to all other baurusuchids and their internal relationships were examined based on the maximum parsimony analysis of a discrete morphological data matrix. Conclusion: The monophyly of Baurusuchidae is supported by a large number of unique characters implying an equally large morphological gap between the clade and its immediate outgroups. -

E. MOLNAR Queensland Museum Fortitude Valley, Qld. 4006 SUMMARY The rostral portion of a crocodilian skull, from the Pleistocene cave deposits of Tea Tree Cave, near Chillagoe, north Queensland, is described as the type of the new genus and species, Quinkana fortirostrum. The form of the alveoli suggests that a ziphodont dentition was present. A second specimen, referred to Quinkana sp. from the Pleistocene cave deposits of Texas Caves, south Queensland, confirms the presence of ziphodont teeth. Isolated ziphodont teeth have also been found in eastern Queensland from central Cape York Peninsula in the north to Toowoomba in the south. Quinkana fortirostrum is a eusuchian, probably related to Pristichampsus. The environments of deposition of the beds yielding ziphodont crocodilians do not provide any evidence for (or against) a fully terrestrial habitat for these creatures. The somewhat problematic Chinese Hsisosuchus chungkingensis shows three apomorphic sebe.cosuchian character states, and is thus considered a sebecosuchian. INTRODUCTION The term ziphodont crocodilian refers to those crocodilians possessing a particular adaptation in which a relatively deep, steep sided snout is combined with laterally flattened, serrate teeth (Langston, 1975). -

Oliveira recovered four crocodyliform specimens from the Early Cretaceous Bahia Supergroup (Recôncavo-Tucano Basin). In the present work, we describe four different fossil specimens: an osteoderm, a fibula, a tibia, and some autopodial bones. No further identification besides Mesoeucrocodylia was made due to their fragmentary nature and the reduced number of recognized synapomorphies for more inclusive clades. With exception of the fibula, all other specimens have at least one particular feature, which with new specimens could represent new species. The new specimens described here increase the known diversity of Early Cretaceous crocodyliforms from Brazil. This work highlights the great fossiliferous -
