Valérie Martin, Varavudh Suteethorn & Eric Buffetaut, Description of the Type and Referred Material of Phuwiangosaurus
ORYCTOS, V ol . 2 : 39 - 91, Décembre 1999 DESCRIPTION OF THE TYPE AND REFERRED MATERIAL OF PHUWIANGOSAURUS SIRINDHORNAE MARTIN, BUFFETAUT AND SUTEETHORN, 1994, A SAUROPOD FROM THE LOWER CRETACEOUS OF THAILAND Valérie MARTIN 1, Varavudh SUTEETHORN 2 and Eric BUFFETAUT 3 1 Musée des Dinosaures, 11260 Espéraza, France 2 Geological Survey Division, Department of Mineral Resources, Rama VI Road, 10400 Bangkok, Thailand 3 CNRS (UMR 5561), 16 cour du Liégat, 75013 Paris, France Abstract : The type specimen of P. sirindhornae Martin, Buffetaut and Suteethorn, 1994 is an incomplete, partly articulated, skeleton discovered in the Phu Wiang area of northeastern Thailand). Most of the abundant sauropod material from the Sao Khua Formation (Early Cretaceous), collected on the Khorat Plateau, in northeastern Thailand, is referable to this species. Phuwiangosaurus is a middle-sized sauropod, which is clearly different from the Jurassic Chinese sauropods (Euhelopodidae). On the basis of a few jaw elements and teeth, P. sirindhornae may be considered as an early representative of the family Nemegtosauridae. Key words : Sauropoda, Osteology, Early Cretaceous, Thailand Description du type et du matériel rapporté de Phuwiangosaurus sirindhornae Martin, Buffetaut et Suteethorn, 1994, un sauropode du Crétacé inférieur de Thaïlande Résumé : Le spécimen type de Phuwiangosaurus sirindhornae est un squelette incomplet, partiellement articulé, découvert dans la région de Phu Wiang (Nord-Est de la Thaïlande). Phuwiangosaurus est un sauropode de taille moyenne (15 à 20 m de longueur) très différent des sauropodes du Jurassique chinois. La majeure partie de l’abondant matériel de sauropodes, récolté sur le Plateau de Khorat (Formation Sao Khua, Crétacé inférieur), est rap - portée à cette espèce. -

A Dinosaur Tail Vertebra Leads Researchers on the Right Track 2 April 2021
A dinosaur tail vertebra leads researchers on the right track 2 April 2021 journal Historical Biology, and now an updated version has been published. Spinosaurs (family Spinosauridae) are large to giant carnivorous dinosaurs that have been familiar to a wide audience since the third film in the Jurassic Park series at the latest. Spinosaurs were often larger than Tyrannosaurus rex! They have a long crocodile-like skull and conical teeth that are also reminiscent of crocodiles. The animals probably ate large fish but also other dinosaurs. Spinosaurs were found almost all over the world, and so some time ago teeth were found in Thailand, which were named Siamosaurus suteethorni. Teeth are, however, hardly suitable for determining the species and so the validity of this spinosaur species has often been questioned since the remains of the skeleton have never been discovered. "When I was a doctoral student at the University of Bonn, I found a tail piece made of eight vertebrae lying unnoticed in a drawer in the Sirindhorn Museum in Thailand," says Dr. Adun Samathi, head of the project. The vertebra looks similar to that of Camarillasaurus from Spain. Camarillasaurus was originally assigned to the so-called ceratosaurs, which also includes Ceratosaurus and Carnotaurus. "But this assignment of Camarillasaurus was problematic because its morphology is more similar Credit: Pixabay/CC0 Public Domain to spinosaurids, including Thai material, than to ceratosaurs," says Samathi. Therefore, Camarillasaurus has been re-examined to better understand the Thai dinosaur. Scientists from Mahasarakham University (Thailand) and the University of Bonn have Things became clearer when Prof. -

Received : August 1979. INTRODUCTION The dinosaur material collected by the Soviet-Mongolian Paleont- ological Expeditions has lately been supplemented by the fragmentary skeletons of unusual carnivorous dinosaurs -the segnosaurids (Perle 1979). The remains of these dinosaurs come from the late Cretaceous de- posits of several localities in SE Mongolia. From this collection, Segno- saurus galbinensis Perle, 1979 has been described up to now (Perle 1979). -

The left and right nasals are fused together as in oviraptorids. Morphology of the jugal, which is not fused with the quadratojugal, and the postorbital indicate that the infratemporal fenestra is completely separate from the orbit, not confluent with the latter, as inferred previously. The left and right dentaries are fused together without a trace of suture. Such newly available information indicates that the skull of Avimimus is not as ‘avian’-like as inferred in previous studies. -

Avialan Status for Oviraptorosauria
Avialan status for Oviraptorosauria TERESA MARYAŃSKA, HALSZKA OSMÓLSKA, and MIECZYSŁAW WOLSAN Maryańska, T., Osmólska, H., and Wolsan, M. 2002. Avialan status for Oviraptorosauria. Acta Palaeontologica Polonica 47 (1): 97–116. Oviraptorosauria is a clade of Cretaceous theropod dinosaurs of uncertain affinities within Maniraptoriformes. All pre− vious phylogenetic analyses placed oviraptorosaurs outside a close relationship to birds (Avialae), recognizing Dromaeo− sauridae or Troodontidae, or a clade containing these two taxa (Deinonychosauria), as sister taxon to birds. Here we pres− ent the results of a phylogenetic analysis using 195 characters scored for four outgroup and 13 maniraptoriform (ingroup) terminal taxa, including new data on oviraptorids. This analysis places Oviraptorosauria within Avialae, in a sister−group relationship with Confuciusornis. Archaeopteryx, Therizinosauria, Dromaeosauridae, and Ornithomimosauria are suc− cessively more distant outgroups to the Confuciusornis−oviraptorosaur clade. Avimimus and Caudipteryx are succes− sively more closely related to Oviraptoroidea, which contains the sister taxa Caenagnathidae and Oviraptoridae. Within Oviraptoridae, “Oviraptor” mongoliensis and Oviraptor philoceratops are successively more closely related to the Conchoraptor−Ingenia clade. Oviraptorosaurs are hypothesized to be secondarily flightless. Emended phylogenetic defi− nitions are provided for Oviraptoridae, Caenagnathidae, Oviraptoroidea, Oviraptorosauria, Avialae, Eumaniraptora, Maniraptora, and Maniraptoriformes.
