tIsolated theropod dinosaur teeth from Ko Kut (Kut Island) in eastern Thailand are referred to an indeter-minate spinosaurid on the basis of their morphology and ornamentation. On the basis of other spinosauridoccurrences in Thailand and other parts of Asia, they support the attribution of the fossil-bearing beds onKo Kut to the Lower Cretaceous rather than the Jurassic. The lack of ornithischian remains in the Ko Kutfaunal assemblage suggests that it is coeval with the Sao Khua Formation (Barremian) of NE Thailand.
