Researchers at Nakhonratchashima Rajabhat University, Thailand, analyzed the fossils of a dinosaur discovered in the Kok Croat geological formation in Korat, Thailand, and found that they were the remains of a dinosaur belonging to the group of Carcharodontosaurus.

Carcharodontosaurus were successful predators, mainly from the Jurassic and Cretaceous periods on several continents. The lack of dinosaurs in this group, however, was related to the fossil finds of the first chalk from Asia. The discovery was made by the researcher Duangsud Chokchaloyemvong and his colleagues. The researchers analyzed various fossilized remains of the skull, spine, extremities and sides, which belonged to at least four specimens of an unknown species.

The latter was then given the name Siamraptor Suwati: the first term resembles Siam, the other name by which Thailand is known.

Researchers have found that this dinosaur can be considered the main member of the Carcharodontosaurus group in the sense that it is evolutionarily separated from the group at an early stage compared to other species belonging to the same group.

This new discovery also confirms that Carcharodontosaurus were widespread on at least three continents (Europe, Africa and Asia) in the early stages of the Cretaceous period. Siamraptor suwati is the most surviving Carcharodontosaurus theropod from Southeast Asia.
