Dinilysia is an extinct genus of snake from the Late Cretaceous of South America.
Jurassic Park FranchiseEdit
Dinilysia never appeared in the Jurassic Park novels or movies.
Jurassic Park III: Park BuilderEdit
It has however appeared in Jurassic Park III: Park Builder. Strangely, it looks nothing like a snake once it is placed in the actual park. It comes from the family Diniysiidae, which is not listed in the game, oddly.
