Siamosaurus

Siamosaurus (meaning "Siamese lizard") is a genus of theropod dinosaur from Barremian Sao Khua Formation in Thailand. The animal is a tooth taxon and therefore details on its size or classification are not certain. The type species, Siamosaurus suteethorni, was formally described by Buffetaut and Ingavat in 1986. It is known from teeth that closely resemble those of Spinosaurus; it may have eaten fish.[1]
