Siamosaurus.
Siamosaurus is a genus of spinosaurid dinosaur from what is now Thailand in the Early Cretaceous period. The first reported spinosaurid from Asia, it is confidently known only from tooth fossils (example pictured). The type species, Siamosaurus suteethorni (named for Thai palaeontologist Varavudh Suteethorn), was formally described in 1986. In 2009, four teeth from China previously attributed to a pliosaur were provisionally identified as possibly those of Siamosaurus. Siamosaurus's body length is uncertain, but has been estimated at 5.1 to 9.1 metres (17 to 30 feet). The teeth, typically 62.5 millimetres (2.46 inches) long, were conical and had longitudinal grooves and wrinkled enamel. It would have had a long, low snout and robust forelimbs, and possibly a sail down its back. Its teeth are similar to those of other spinosaurids, and it may not be a dinosaur at all. Its teeth were suitable for impaling rather than tearing, and it may have eaten fish, pterosaurs and small dinosaurs. It lived in a semi-arid habitat of floodplains and rivers.
