COCODRILIFORMES DE LA FORMACION SIERRA PERENCHIZA (CRETACICO SUPERIOR DE VALENCIA, ESPAÑA) Julio COMPANY, Xabier PEREDA-SUBERBIOLA & José Ignacio RUIZ-OMEÑACA La Formación Sierra Perenchiza (Campaniense superior-Maastrichtiense) constituye una unidad carbonática continental expuesta de forma discontinua a lo largo del margen sudoriental de la Cadena Ibérica. En las áreas de Chera y Tous, los niveles lacustres y palustres de dicha formación han proporcionado abundantes restos de dinosaurios y pterosaurios (Company et al., 1998, 1999b). Asímismo, restos de cocodrilos y otros vertebrados han sido obtenidos mediante prospección superficial y lavado de sedimentos (Company et al., 1999a). Los restos de cocodriliformes consisten en huesos craneales y mandibulares, dientes aislados, vértebras, huesos apendiculres y osteodermos. En los afloramientos localizados en los alrededores de Chera han sido hallados dos alligatoroideos frecuentes en otros yacimientos campano-maastrichtienses de España y Francia: Acynodon y Musturzabalsuchus. Ambos géneros están representados por huesos mandibulares y dientes aislados. También han sido hallados restos de un nuevo cocodrílido zifodonto, claramente diferenciable de Doratodon, un mesoeucocodrílido del Cretácico superior de Austria y Rumanía. Otros cocodriliformes están representados únicamente por dientes aislados. La posesión de raíces simples, separadas por una ligera constricción de las coronas dentales, así como la peculiar la ornamentación del esmalte, permiten su asignación a este clado (Larsson & Sidor, 1999). Hasta nueve morfotipos dentales pueden ser diferenciados en función de las características del esmalte, de la presencia o ausencia de carenas y por la morfología de la corona. No se descarta la posibilidad de que más de un morfotipo forme parte de una misma dentición heterodonta. Varios de estos morfotipos dentales recuerdan a los dientes acanalados de algunos «trematochámpsidos»; otros son más semejantes a los dientes de ciertos atoposaúridos del Jurásico superior y Cretácico inferior, y hay un último morfotipo con unas características muy similares a las de los dientes bunodontos de Bernissartia. Dientes similares han sido citados recientemente en varios yacimientos del Cretácico superior (Galton, 1996; Lee, 1997; Debeljak et al., 1999). Diversos elementos craneales, restos del esqueleto axial y postcraneal, así como fragmentos de osteodermos, no han sido por el momento asignados a taxón alguno. Finalmente, en el yacimiento paleontológico de Tous se han recuperado tres nuevos morfotipos dentales, diferentes de los mencionados con anterioridad. Estos morfotipos presentan una gradación de coronas altas y bajas. Las características del esmalte son similares en todos ellos, por lo que se cree que pueden representar piezas dentales de una única dentición heterodonta. Estos dientes son asignados, con reserva, a Allodaposuchus, un eusuquio del Cretácico superior europeo (Buscalioni, et al. 1999, Grigorescu et al., 1999). CROCODYLIFORMES FROM THE LATE CRETACEOUS SIERRA PERENCHIZA FORMATION OF VALENCIA, SPAIN. The Upper Campanian-Maastrichtian Sierra Perenchiza Formation is a carbonated unit discontinuously exposed along the southeastern margin of the Iberian Chain. In Chera and Tous areas (Valencia Province), the lacustrine and palustrine sediments of this formation have yielded a diverse vertebrate fauna, mainly dinosaurs and pterosaurs (Company et al., 1998, 1999b). In addition, crocodilians and lower vertebrates are not rare, and have been recorded by surface prospecting and screening (Company et al., 1999a). The recovered crocodyliform specimens consist of skull and jaw bones, isolated teeth, vertebrae, appendicular bones and osteoderms. At Chera sites, two taxa have been identified at the generic level. The alligatorids Acynodon and Musturzabalsuchus, frequent in Campano-Maastrichtian beds from northern Iberian Peninsula and southern France, are represented by jaw bones and isolated teeth. A new ziphodont form is represented by a well-preserved dentary and by several isolated teeth. This crocodyliform is clearly different from Doratodon, a mesoeucrocodylian from the Late Cretaceous of Austria and Rumania. 22 5TH EWVP - ABSTRACTS. ZUSAMMENFASSUNGEN. RESUMEES. RESUMENES. Other crocodyliforms are represented by isolated teeth. Crocodyliform assignment is based on the presence of single roots, constricted crown-root junctions and enamel ornamentation (Larsson and Sidor, 1999). Among the sieved specimens, up to nine tooth morphs have been differentiated on the basis of the overall morphology, features of the enamel surface (smooth, wrinkled or fluted) and presence of carinae. Some of the different morphotypes probably represent teeth from different regions of the same tooth row, indicating a heterodont dentition. In these cases, additional data are required for taxonomic assignment. Some of these dental types resemble the fluted teeth of the "trematochampsids", the striated leaf-shaped teeth of the Upper Jurassic-Lower Cretaceous atoposaurids and the wrinkled bunodont teeth of the durophagous Bernissartia. Recently, similar teeth have been recovered from other Late Cretaceous localities (Galton, 1996; Lee, 1997; Debeljak et al., 1999). Several isolated cranial elements, axial and appendicular bones and fragmentary osteoderms have not been assigned to any known taxa. Lastly, the Tous locality has produced three distinct dental morphotypes, different from those of Chera sites. Dental shape varies from high to low and blunt crowns. The enamel ornamentation is essentially the same, so they also could represent different tooth positions of a single heterodont taxon. At present, they all are assigned to cf. Allodaposuchus, an eusuchian crocodile known from the Late Cretaceous of southern and central Europe (Buscalioni, et al. 1999, Grigorescu et al., 1999). Buscalioni, A. D., F. Ortega, and D.

  • A New Sebecid Mesoeucrocodylian from the Rio Loro Formation (Palaeocene) of North-Western Argentina
    Zoological Journal of the Linnean Society, 2011, 163, S7–S36.

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.

  • 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).

It is referred to the genus Doratodon as D. ibericus sp. nov. To date, Doratodon (type-species D. carcharidens) was only known by fragmentary cranial remains from the Campanian of Muthmannsdorf (Austria). This genus was previously regarded either as a goniopholid or as a hsisosuchid within the Mesoeucrocodylia, but a phylogenetic analysis suggests that Doratodon is a member of Zipho- suchia, placing it as the sister taxon of Sebecosuchia. Doratodon shares with Sebecosuchia (including Bergisuchus) features concerning the shape and implantation of teeth (margins of tooth crowns with denticulate carinae; tip of tooth crowns caudally curved; tooth implantation in isolated alveoli).

Notosuchia is a diverse clade of Crocodyliformes that achieved a remarkable 18 diversity during the Cretaceous. This group is particularly abundant in continental 19 deposits of Gondwana throughout the Cretaceous, especially in South America. 20 Notosuchia was first recognized as a distinct group by the early work of Gasparini in the 21 1970’s and in the last decades numerous discoveries and studies have increased the 22 geographical, temporal and taxonomical scope of this clade. Here we analyze the 23 patterns of diversity of Notosuchia during the Cretaceous, considering their taxic and 24 phylogenetic diversity, as well as implementing sampling corrections aiming to account 25 for the uneven fossil record of different stages of the Cretaceous. We identify two 26 subsequent pulses of diversification in the late Early Cretaceous and the middle Late 27 Cretaceous, followed by two separate extinction events that occurred during the latest 28 Cretaceous (Campanian/Maastrichtian). We discuss the contribution of the South 29 American, African, and Malagasy fossil records to the diversity curves, which indicates 30 the African fossil record dominates the first pulse of diversification and the South 31 American fossil record exclusively compose the second pulse of diversification.

  • A Late Creatceous (Santonian) Terrestrial Ecosystem in the Western
    A Late Cretaceous (Santonian) terrestrial ecosystem in the western Tethyan archipelago: the Central European Iharkút vertebrate site (Csehbánya Formation, Hungary) ATTILA ŐSI1 1Hungarian Academy of Sciences – Hungarian Natural History Museum, Research Group for Palaeontology, Ludovika tér 2, Budapest, 1083, Hungary; e-mail: [email protected] ABSTRACT The faunal composition and paleobiogeographic relationships of the single known Mesozoic terrestrial site from Hungary (Central Europe) is reviewed here. This Late Cretaceous (Santonian) locality at Iharkút, discovered in 2000, provided more than 10.000 bones and teeth of close to 30 different vertebrate groups. These include pycnodontiform and lepisosteid fishes, the unique Hungarobatrachus and discoglossid, paleobatrachid and pelobatid frogs, albanerpetontids, various types of scincomorph lizards, mosasaurs, bothremydid, dortokid and cryptodiran turtles, sebecosuchian, hylaeochampsid, and two additional unidentified crocodylomorphs, azhdarchid pterosaurs, nodosaurid ankylosaurs, rhabdodontid ornithopods, coronosaurian ceratopsians, basal tetanuran, abelisaurid, and paravian theropods, and at least two different enantiornithine birds. Comparison of the Iharkút fauna with those of other European Late Cretaceous localities from Romania, Austria, France and Spain reveals close similarities in family level, however the genera and/or species of the individual areas are alrealy different. This can be explained first, by the Santonian age of the Iharkút locality being slightly older than the
