Spinosaurid teeth from the Lower Cretaceous of Ko Kut, eastern Thailand.

[Dents de spinosauridÃs du CrÃtacÃ infÃrieur de Ko Kut, Est de la ThaÃlande]

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