Is this a diplodocid tooth form Lourinhã Formation ? 

[Troodon]

Diplodocid are more pencil shaped these cone-chisel teeth are better assigned to Macronaria indet. based on what published papers are referring to this morphology.  Still a cool sauropod tooth from Portugal.   Quite a few sauropods in this fauna and most are not described.
