Zusammenfassung: | The ichnological assemblage of the Phra Wihan Formation (early Early Cretaceous of northeastern Thailand) includes the first sauropod tracks ever found in Thailand. It is reminiscent of the fauna of the underlying Jurassic Phu Kradung Formation with theropods, small ornithischians of uncertain affinities (possibly
Hypsilophodon-like ornithopods) and sauropods. It suggests that, in southeastern Asia, an important faunal change occurred in the Early Cretaceous among continental vertebrates, whereas little happened at the Jurassic–Cretaceous boundary.
L’assemblage ichnologique de la formation Phra Wihan (Crétacé basal de Thaïlande) comprend les premières traces de sauropode découvertes en Thaïlande. Il rappelle la faune de la formation sous-jacente, la formation Phu Kradung avec des théropodes, des sauropodes et de petits ornithischiens aux affinités incertaines (peut-être des ornithopodes de type
Hypsilophodon). Cette composition faunique suggère qu’un remplacement de faune important est survenu en Thaïlande au début du Crétacé, plutôt qu’à la limite Jurassique–Crétacé. |
