    • my guess is the top part of an oyster?

    • It may or may not be a tooth but it looks like a highly weathered tooth particularly with the carinae (cutting edge) but I don’t know from what.

    • @jean-rosario Given the closest fossilierous exposures look to be miocene and the fact that the crocodilian fossils of cuba are poorly understood, my bet would be that this comes from one of them. That said, it also strongly resembles a mosasaur tooth and there are cretaceous exposures not too terribly far away.
