Goniopholis phuwiangensis nov. sp., a newmesosuchian crocodile from the Mesozoic of north-eastern Thailand

A new Berriasian species ofGoniopholis(Mesoeucrocodylia, Neosuchia) from England, and a review of the genus

“…In this traditional sense (e.g. Hulke, 1878; Owen, 1878; Buffetaut, 1982), the use of the name Goniopholis is linked to characters of tooth (crown) morphology, osteoderms that are wider than long (bearing an anterior process at the anterolateral corner), and confluence of alveoli 3–4 (see Buffetaut, 1982; Buffetaut & Ingavat, 1983). As seen here, these characters are present in other clades (e.g.…”

“…With this comprehensive analysis at hand, the relationships of goniopholidids are tested, as is their placement in the broad context of crocodylomorph evolution, and key characters and clades are discussed. We also preliminarily explore the relationships of ‘ Goniopholis ’ phuwiangensis Buffetaut & Ingavat, 1983 (Lower Cretaceous, Thailand) and Denazinosuchus kirtlandicus (Wiman, 1932) (Upper Cretaceous, USA) to evaluate their original placement in Goniopholis . Finally, we comment on the distribution of Goniopholididae, which should be further explored in future works.…”

“…Based on the information on the provenance of specimens provided by Buffetaut & Ingavat (1983) and Lauprasert et al . (2007), results herein support the occurrence of two different goniopholidid taxa in the pre‐Aptian of Sao Khua Formation of Phu Phok (Thailand).…”

Atoposaurid crocodyliforms from the Khorat Group of Thailand: first record of Theriosuchus from Southeast Asia

“…The genus Theriosuchus currently includes three valid species: T. pusillus Owen 1878, T. ibericus Brinkmann 1992 and T. guimarotae Schwarz and Salisbury 2005. Field excavations in the Late Jurassic to Early Cretaceous Khorat Group of Thailand have taken place for almost 30 years as part of an international collaboration between mainly Thai and French institutions, but also partners from Denmark and Switzerland. As part of this programme, three taxa of the family Goniopholididae (Sunosuchus thailandicus Buffetaut andIngavat 1980, Goniopholis phuwiangensis Buffetaut andIngavat 1983 and Siamosuchus phuphokensis Lauprasert et al 2007) plus a taxon of unclear taxonomic affinity (Khoratosuchus jintasakuli Lauprasert et al 2009) had been found and described. Beside these taxa, a number of fossils belonging to a dwarf crocodyliform have been unearthed and are currently housed in the collection of the Sirindhorn Museum, Department of Mineral Resources, Kalasin Province and in the collection of the Palaeontological Research and Education Centre, Mahasarakham University, Maha Sarakham Province.…”

Late Jurassic <i>Sunosuchus</i> (Crocodylomorpha, Neosuchia) from the Qigu Formation in the Junggar Basin (Xinjiang, China)

“…However, it is well in accordance with long time ranges for the closely related taxon Goniopholis, which is present in Europe from Middle Jurassic (Bathonian) to Early Cretaceous (Abtian) strata. Geographically, Sunosuchus is currently restricted to Asia, with possible overlap with Goniopholis phuwiangesis (Buffetaut & Ingavat 1983) and the goniopholidid Siamosuchus phuphokensis (Lauprasert et al 2007) in Thailand. The geographical restriction is also evident in other members of Goniopholididae and might correspond to existing geographical barriers, such as the opening North Atlantic between North America and Europe and the Tethyan ocean between the European archipelago and the Asian land mass during the Jurassic and Cretaceous, which led to a separation of a North American group of goniopholidids that possibly all belong to Eutretauranosuchus (Salisbury et al 1999), the European Goniopholis, and the Asian Sunosuchus discussed herein.…”
