Siamraptor suwati is a species Carcharodontosaurid theropod dinosaur that was lived approxi

mately 120 million years ago at Early Cretaceous period. This species was a member of Carcharodontosauria, a group of large carnivorous theropods from the Jurassic and Cretaceous periods. The Siamraptor itself is the oldest carcharodontosaurian dinosaur known and is the first of its kind from Southeast Asia. [1][2]

The fossilized remains of at least four Siamraptor suwati specimens, skulls, backbone, limbs, and hips; were recovered from the Khok Kruat Formation in Nakhon Ratchasima province, Thailand. The fossils were analyzed by Dr. Duangsuda Chokchaloemwong of Nakhon Ratchaima Rajabhat University and her colleagues from Thailand & Japan.

Their phylogenetic analyses revealed that Siamraptor is indeed a basal species of Carcharodontosauria, involving a new sight of the paleobiogeographical context of this group; the paleontologists have concluded

Siamraptor Suwati is the best known preserved carcharodontosaurian theropod from Southeast Asia, that its discovery sheds a new light on the evolutionary history of Carcharodontosauria.

Biology

Siamraptors were, like all known Charcarodontosaurids, Predatory theropods that consume any prey animal avaiable. The Siamraptors might've co-existed and/or competed with other species of large theropods, such as spinosaurid Siamosaurus.
