  • A New Species of the Sauropsid Reptile Nothosaurus from the Lower Muschelkalk of the Western Germanic Basin, Winterswijk, the Netherlands
    A new species of the sauropsid reptile Nothosaurus from the Lower Muschelkalk of the western Germanic Basin, Winterswijk, The Netherlands NICOLE KLEIN and PAUL C.H. ALBERS Klein, N. and Albers, P.C.H. 2009. A new species of the sauropsid reptile Nothosaurus from the Lower Muschelkalk of the western Germanic Basin, Winterswijk, The Netherlands. Acta Palaeontologica Polonica 54 (4): 589–598. doi:10.4202/ app.2008.0083 A nothosaur skull recently discovered from the Lower Muschelkalk (early Anisian) locality of Winterswijk, The Nether− lands, represents at only 46 mm in length the smallest nothosaur skull known today. It resembles largely the skull mor− phology of Nothosaurus marchicus. Differences concern beside the size, the straight rectangular and relative broad parietals, the short posterior extent of the maxilla, the skull proportions, and the overall low number of maxillary teeth. In spite of its small size, the skull can not unequivocally be interpreted as juvenile. It shows fused premaxillae, nasals, frontals, and parietals, a nearly co−ossified jugal, and fully developed braincase elements, such as a basisphenoid and mas− sive epipterygoids. Adding the specimen to an existing phylogenetic analysis shows that it should be assigned to a new species, Nothosaurus winkelhorsti sp. nov., at least until its juvenile status can be unequivocally verified. Nothosaurus winkelhorsti sp. nov. represents, together with Nothosaurus juvenilis, the most basal nothosaur, so far. Key words: Sauropterygia, Nothosaurus, ontogeny, Anisian, The Netherlands.

  • A New Plesiosaur from the Lower Jurassic of Portugal and the Early Radiation of Plesiosauroidea
    A new plesiosaur from the Lower Jurassic of Portugal and the early radiation of Plesiosauroidea EDUARDO PUÉRTOLAS-PASCUAL, MIGUEL MARX, OCTÁVIO MATEUS, ANDRÉ SALEIRO, ALEXANDRA E. FERNANDES, JOÃO MARINHEIRO, CARLA TOMÁS, and SIMÃO MATEUS Puértolas-Pascual, E., Marx, M., Mateus, O., Saleiro, A., Fernandes, A.E., Marinheiro, J., Tomás, C. and Mateus, S. 2021. A new plesiosaur from the Lower Jurassic of Portugal and the early radiation of Plesiosauroidea. Acta Palaeontologica Polonica 66 (2): 369–388. A new plesiosaur partial skeleton, comprising most of the trunk and including axial, limb, and girdle bones, was collected in the lower Sinemurian (Coimbra Formation) of Praia da Concha, near São Pedro de Moel in central west Portugal. The specimen represents a new genus and species, Plesiopharos moelensis gen. et sp. nov. Phylogenetic analysis places this taxon at the base of Plesiosauroidea. Its position is based on this exclusive combination of characters: presence of a straight preaxial margin of the radius; transverse processes of mid-dorsal vertebrae horizontally oriented; ilium with sub-circular cross section of the shaft and subequal anteroposterior expansion of the dorsal blade; straight proximal end of the humerus; and ventral surface of the humerus with an anteroposteriorly long shallow groove between the epipodial facets. In addition, the new taxon has the following autapomorphies: iliac blade with less expanded, rounded and convex anterior flank; highly developed ischial facet of the ilium; apex of the neural spine of the first pectoral vertebra inclined posterodorsally with a small rounded tip. This taxon represents the most complete and the oldest plesiosaur species in the Iberian Peninsula.

Lake Shore Drive, Chicago, IL 60605-2496, USA (Received 31 July 2012; accepted 25 February 2013) Abstract – Largocephalosaurus polycarpon Cheng et al. 2012a was erected after the study of the skull and some parts of a skeleton and considered to be an eosauropterygian. Here we describe a new species of the genus, Largocephalosaurus qianensis, based on three specimens. The new species provides many anatomical details which were described only briefly or not at all in the type species, and clearly indicates that Largocephalosaurus is a saurosphargid. It differs from the type species mainly in having three premaxillary teeth, a very short retroarticular process, a large pineal foramen, two sacral vertebrae, and elongated small granular osteoderms mixed with some large ones along the lateral most side of the body. With additional information from the new species, we revise the diagnosis and the phylogenetic relationships of Largocephalosaurus and clarify a set of diagnostic features for the Saurosphargidae Li et al.

  • Tesis Doctoral 2018
    TESIS DOCTORAL 2018 HISTORIA EVOLUTIVA DE SIMOSAURIDAE (SAUROPTERYGIA). CONTEXTO SISTEMÁTICO Y BIOGEOGRÁFICO DE LOS REPTILES MARINOS DEL TRIÁSICO DE LA PENÍNSULA IBÉRICA CARLOS DE MIGUEL CHAVES PROGRAMA DE DOCTORADO EN CIENCIAS FRANCISCO ORTEGA COLOMA ADÁN PÉREZ GARCÍA RESUMEN Los sauropterigios fueron un exitoso grupo de reptiles marinos que vivió durante el Mesozoico, apareciendo en el Triásico Inferior y desapareciendo a finales del Cretácico Superior. Este grupo alcanzó su máxima disparidad conocida durante el Triásico Medio e inicios del Triásico Superior, diversificándose en numerosos grupos con distintos modos de vida y adaptaciones tróficas. El registro fósil de este grupo durante el Triásico es bien conocido a nivel global, habiéndose hallado abundantes restos en Norteamérica, Europa, el norte de África, Oriente Próximo y China. A pesar del relativamente abundante registro de sauropterigios triásicos ibéricos, los restos encontrados son, por lo general, elementos aislados y poco informativos a nivel sistemático en comparación con los de otros países europeos como Alemania, Francia o Italia. En la presente tesis doctoral se realiza una puesta al día sobre el registro ibérico triásico de Sauropterygia, con especial énfasis en el clado Simosauridae, cuyo registro ibérico permanecía hasta ahora inédito. Además de la revisión de ejemplares de sauropterigios previamente conocidos, se estudian numerosos ejemplares inéditos. De esta manera, se evalúan hipótesis previas sobre la diversidad peninsular de este clado y se reconocen tanto formas definidas en otras regiones europeas y de Oriente Próximo, pero hasta ahora no identificadas en la península ibérica, como nuevos taxones. La definición de nuevas formas y el incremento de la información sobre otras previamente conocidas permiten la propuesta de hipótesis filogenéticas y la redefinición de varios taxones.
