?Ornithischian dinosaurs in Southeast Asia: a review with palaeobiogeographic implications

Ornithischian dinosaurs have been discovered in Thailand, Laos, and Malaysia. These bird-hipped herbivores remain relatively rare by comparison with saurischian dinosaurs. In the Late Jurassic, stegosaurs basal neornithischians from Thailand showed similarities to Middle-Late Jurassic taxa China. Ornithischians appeared fossil record again during late Early Cretaceous (Aptian-Albian) of Laos. They are represented non-hadrosaurid iguanodontians ceratopsians. A few specimens reported poorly dated rocks Here, we illustrate diversity ornithischian assemblages Southeast Asia discuss their palaeobiogeographical implications.
