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.

来自泰国东部Ko Kut下白垩纪的棘龙齿

来自泰国东部Ko Kut（库特岛）的兽脚类恐龙牙齿根据其形态和装饰被称为不确定的棘龙。根据在泰国和亚洲其他地区发生的其他棘龙类事件，它们支持将库古特岛上的化石床归因于白垩纪而不是侏罗纪。Ko Kut动物群组合中缺少鸟眼动物，这表明它与泰国东北部的Sao Khua组（巴雷米亚）处于同一时期。
