Alguns Crocodilianos São Mencionados Do Cretácico Português Paleo-herpetofauna de Portugal 69 Crocodlllanos Alguns Crocodilianos são mencionados do Cretácico português. No entanto, boa parte deste material carece de revisão e a sua classificação dos reajustamentos consequentes Do Cenomaniano Médio de Viso é referido um Mesosuchia/ Goniopholididae, Oweniasuchus lusitanicus Sauvage, 1897. Também do Maestrichtiano desta mesma localidade foram recolhidos numerosos frag­ mentos ósseos, identificados como pertencendo a Crocodylus blavieri Gray (Sauvage 1897/98 in Jonet 1981). No entanto Antunes & Pais (1978) colocaram algumas dúvidas a esta última identificação, referindo que so­ mente com base nos fragmentos encontrados, tanto poderia tratar-se de um mesossuquiano como de um eussuquiano. Restos de uma forma que consideraram semelhante à descrita, descoberta no Cretácico Superior de Taveiro, foi por eles identificada como sendo um Mesosuchia, n.gén., n.sp. (=Crocodylus blavieri Gray). Vestígios de exemplares desta forma, não designada, foram igualmente encontrados no Cacém. Do Cenomaniano Médio desta última localidade são também mencionados por Jonet (1981), os Mesosuchia/ Goniopholididae: Goniopholis cf. crassidens Owen, 1841 (pequeno crocodilo de cerca de 2 metros, também conhecido de Wealden - Cretácico Inferior - de Inglaterra e do Cretácico Inferior de Teruel), Oweniasuchus lusitanicus Sauvage, 1897, Oweniasuchus aff.lusitanicus, Oweniasuchus pulchelus Jonet, 1981 e, com dúvidas, o Eusuchia/ Crocodylidae, Thoracosaurus Leidy, 1852 sp .. Oweniasuchus pulchelus é também referido do Cenomaniano Superior de Carenque/Sintra (Jonet 1981) e Oweniasuchus sp., do Cenomaniano Médio de Forte Junqueiro/ Lisboa (Jonet 1981). 70 E. G. Crespo Restos indeterminados de Crocodilianos foram também encontrados no Cenomaniano Médio de Belas, Alto Pendão (Vale Figueira) e de Agualva/Cacém (todas localidades dos arredores de Lisboa) e do Cretácico Superior de Aveiro e das Azenhas do Mar (Sintra). Do Cretácico espanhol são referidos numerosos Crocodilianos com predominio dos Goniopholididae, Bernissartidae e Atoposauridae, tal como de resto acontecia na Europa Ocidental (Quesada et ai 1998; Sanz et ai 1990; Busca1ioni et ai 1999). Os Atoposauridae eram os que tinham hábitos mais terrestres. Eram pequenos crocodilos de 25170 cm de comprimento. Do Cretácico Inferior de Espanha são mencionados: Lisboasaurus estesi/ Metasuchia (Cuenca), também referido do Jurássico Superior de Portugal; Goniopholis sp./Goniopholididae (Cuenca, Teruel, Castellón, Saragoça, Burgos, Valência, Zamora, Sória); Goniopholis cf. crassidens/Goniopholididae (Teruel); Goniopholis cf. simus, também referido do Jurássico Superior de Portugal (Castellón); Machimosaurus/ Goniopholididae, também referido do Jurássico Superior de Portugal (Valência); Theriosuchus sp./Atoposauridae (Teruel, Lérida, Castellón); Theriosuchus pusillus (Cuenca); Theriosuchus ibericus (Cuenca); Montsechosuchus depereti / Atoposauridae (Lérida); Montsechosuchus sp.

Received: 15 December 2013 / Accepted: 18 December 2014 / Available online: 25 March 2015 Abstract In 2011 the partial skeleton of a goniopholidid crocodylomorph was recovered in the ENDESA coal mine Mina Corta Barrabasa (Escu- cha Formation, lower Albian), located in the municipality of Andorra (Teruel, Spain). This new goniopholidid material is represented by abundant postcranial and fragmentary cranial bones. The study of these remains coincides with a recent description in 2013 of at least two new species of goniopholidids in the palaeontological site of Mina Santa María in Ariño (Teruel), also in the Escucha Formation. These species are Anteophthalmosuchus escuchae, Hulkepholis plotos and an undetermined goniopholidid, AR-1-3422. In the present paper, we describe the postcranial and cranial bones of the goniopholidid from Mina Corta Barrabasa and compare it with the species from Mina Santa María.

  • Steneosaurus Brevior
    The mystery of Mystriosaurus: Redescribing the poorly known Early Jurassic teleosauroid thalattosuchians Mystriosaurus laurillardi and Steneosaurus brevior SVEN SACHS, MICHELA M. JOHNSON, MARK T. YOUNG, and PASCAL ABEL Sachs, S., Johnson, M.M., Young, M.T., and Abel, P. 2019. The mystery of Mystriosaurus: Redescribing the poorly known Early Jurassic teleosauroid thalattosuchians Mystriosaurus laurillardi and Steneosaurus brevior. Acta Palaeontologica Polonica 64 (3): 565–579. The genus Mystriosaurus, established by Kaup in 1834, was one of the first thalattosuchian genera to be named. The holotype, an incomplete skull from the lower Toarcian Posidonienschiefer Formation of Altdorf (Bavaria, southern Germany), is poorly known with a convoluted taxonomic history. For the past 60 years, Mystriosaurus has been consid- ered a subjective junior synonym of Steneosaurus. However, our reassessment of the Mystriosaurus laurillardi holotype demonstrates that it is a distinct and valid taxon. Moreover, we find the holotype of “Steneosaurus” brevior, an almost complete skull from the lower Toarcian Whitby Mudstone Formation of Whitby (Yorkshire, UK), to be a subjective ju- nior synonym of M. laurillardi. Mystriosaurus is diagnosed in having: a heavily and extensively ornamented skull; large and numerous neurovascular foramina on the premaxillae, maxillae and dentaries; anteriorly oriented external nares; and four teeth per premaxilla. Our phylogenetic analyses reveal M. laurillardi to be distantly related to Steneosaurus bollensis, supporting our contention that they are different taxa. Interestingly, our analyses hint that Mystriosaurus may be more closely related to the Chinese teleosauroid (previously known as Peipehsuchus) than any European form. Key words: Thalattosuchia, Teleosauroidea, Mystriosaurus, Jurassic, Toarcian Posidonienschiefer Formation, Whitby Mudstone Formation, Germany, UK.

All these remains were referred to Goniopholididae indet. on the basis of the following combination of features: a relatively narrow and long snout, contribution of splenials to the mandibular symphysis, dermal sculpturing consists of almost circular and slightly elongated oval pits, polygonal ventral osteoderms, and conical teeth with strongly striated crowns with weakly developed unserrated lateral carinae. The Berezovsk goniopholidid represents one of the oldest goniopholidid records in Asia and, geographically, the northernmost occurrence of this group in the Jurassic of Asia.

  • New Transitional Fossil from Late Jurassic of Chile Sheds Light on the Origin of Modern Crocodiles Fernando E
    www.nature.com/scientificreports OPEN New transitional fossil from late Jurassic of Chile sheds light on the origin of modern crocodiles Fernando E. Novas1,2, Federico L. Agnolin1,2,3*, Gabriel L. Lio1, Sebastián Rozadilla1,2, Manuel Suárez4, Rita de la Cruz5, Ismar de Souza Carvalho6,8, David Rubilar‑Rogers7 & Marcelo P. Isasi1,2 We describe the basal mesoeucrocodylian Burkesuchus mallingrandensis nov. gen. et sp., from the Upper Jurassic (Tithonian) Toqui Formation of southern Chile. The new taxon constitutes one of the few records of non‑pelagic Jurassic crocodyliforms for the entire South American continent. Burkesuchus was found on the same levels that yielded titanosauriform and diplodocoid sauropods and the herbivore theropod Chilesaurus diegosuarezi, thus expanding the taxonomic composition of currently poorly known Jurassic reptilian faunas from Patagonia. Burkesuchus was a small‑sized crocodyliform (estimated length 70 cm), with a cranium that is dorsoventrally depressed and transversely wide posteriorly and distinguished by a posteroventrally fexed wing‑like squamosal. A well‑defned longitudinal groove runs along the lateral edge of the postorbital and squamosal, indicative of a anteroposteriorly extensive upper earlid. Phylogenetic analysis supports Burkesuchus as a basal member of Mesoeucrocodylia. This new discovery expands the meagre record of non‑pelagic representatives of this clade for the Jurassic Period, and together with Batrachomimus, from Upper Jurassic beds of Brazil, supports the idea that South America represented a cradle for the evolution of derived crocodyliforms during the Late Jurassic. In contrast to the Cretaceous Period and Cenozoic Era, crocodyliforms from the Jurassic Period are predomi- nantly known from marine forms (e.g., thalattosuchians)1.

  • Big-Headed Marine Crocodyliforms and Why We Must Be Cautious When Using Extant Species As Body Length Proxies for Long-Extinct Relatives
    Palaeontologia Electronica palaeo-electronica.org Big-headed marine crocodyliforms and why we must be cautious when using extant species as body length proxies for long-extinct relatives Mark T. Young, Márton Rabi, Mark A. Bell, Davide Foffa, Lorna Steel, Sven Sachs, and Karin Peyer ABSTRACT Body size is commonly used as a key variable for estimating ecomorphological trends at a macroevolutionary scale, making reliable body length estimates of fossil taxa critically important. Crocodylomorphs (extant crocodylians and their extinct rela- tives) evolved numerous 'aberrant' body-plans during their ~230 million-year history, ranging from ‘hooved’ terrestrial species to dolphin-like pelagic species. Such clades evolved distinct cranial and femoral scaling ratios (compared to total body length), thereby making extant taxa unsuitable proxies for estimating their body lengths. Here we illustrate that the fossil clade Teleosauridae also fits into this category. Teleosaurids were a predominately shallow marine clade that had a global distribution during the Jurassic. Known to have evolved a wide range of body lengths (2–5 m based on com- plete skeletons), there is currently no way of reliably estimating the size of incomplete specimens. This is surprising, as some teleosaurids have been considered very large (9–10 m in total length), thus making Teleosauridae the largest bodied clade during the first 100 million years of crocodylomorph evolution. Our examination and regression analyses of the best preserved teleosaurid skeletons demonstrates that: they were smaller than previously thought, with no known specimen exceeding 7.2 m in length; and that they had proportionally large skulls, and proportionally short femora, when compared to body length.

    Vorwort. Indem ich hiermit als ersten Teil einer Reihe von Arbeiten über die Entwicklung der Eeptilien einen Beitrag zur Biologie und Entwicklung der äufseren Körperform von Crocodilus madagascariensis Grand, der Öffentlichkeit übergebe, drängt es mich, an erster Stelle der Akademie der Wissenschaften in Berlin meinen ergebensten Dank abzustatten für die mir während meines Aufenthaltes in Majunga auf Madagaskar bereit- willigst gewährte Unterstützung von 5000 Mark zur Fortführung meiner Untersuchungen über die Entwicklung der Krokodile. Ferner danke ich an diesem Orte Herrn Professor Dr. A. Götte, dem Direktor des zoologischen Instituts in Strafsburg, für die Liberalität, mit der er mir am zoologischen Institut in Strafsburg ein Arbeitszimmer zur Verfügung stellte, für das rege Interesse, mit dem er das Fortschreiten meiner Arbeiten begleitete und für die mannigfaltigen An- regungen und Fingerzeige, durch die er mir auch in praktischer Hinsicht meine Unter- suchungen vielfach erleichtert hat.

Obgleich gerade in neuerer Zeit viele Naturforscher ihre Aufmerksamkeit auf die Entwicklung der Reptilien gerichtet haben, sind doch bis jetzt die Krokodile nach dieser Hinsicht nur wenig untersucht worden. Der Grund liegt ohne Zweifel in der grofsen Schwierigkeit, sich Eier und Embryonen dieser Reptilien zu verschaffen, denn die Aus- sicht auf ein eingehendes Studium besonders jüngerer Stadien von Embryonen dieser in mancher Beziehung von dem Typus der übrigen Wirbeltiere so sehr abweichenden Tiere würde wohl manchen Zoologen veranlafst haben, jede Möglichkeit zur Erlangung von Material, wenn sich die Gelegenheit dazu geboten hätte, zu erfafsen.

  • A New Blunt-Snouted Dyrosaurid, Anthracosuchus Balrogus Gen. Et Sp
    Historical Biology, 2014 http://dx.doi.org/10.1080/08912963.2014.918968 A new blunt-snouted dyrosaurid, Anthracosuchus balrogus gen. et sp. nov. (Crocodylomorpha, Mesoeucrocodylia), from the Palaeocene of Colombia Alexander K. Hastingsa,b*, Jonathan I. Blocha and Carlos A. Jaramilloc aFlorida Museum of Natural History, University of Florida, Gainesville, FL, USA; bGeiseltalmuseum, Zentralmagazin Naturwissenschaftlicher Sammlungen, Martin Luther Universita¨t Halle-Wittenberg, Halle (Saale), Germany; cSmithsonian Tropical Research Institute, Balboa-Ancon, Panama (Received 23 March 2014; accepted 24 April 2014) A new exceptionally brevirostrine dyrosaurid is described from the middle Palaeocene (58–60 million years ago) Cerrejo´n Formation, northeastern Colombia, based on four partial skulls and associated postcrania. This taxon is unique among dyrosaurids not only in skull shape, but also in having orbital tuberosities, and osteoderms that are dorsoventrally thick and unpitted, a trait otherwise unknown in Crocodylomorpha. Results from a cladistic analysis of Dyrosauridae suggest that the new taxon, together with Cretaceous–Palaeocene Chenanisuchus lateroculi from Africa and Cerrejonisuchus improcerus also from the Cerrejo´n Formation, are the most basal members of the family. Results from a biogeographic analysis indicate at least three independent dispersals of dyrosaurids from Africa to the New World occurred in the Late Cretaceous or early Palaeocene. Widely set orbits in the new taxon indicate a deviation from surface-based predation,
