By the Cretaceous, modern-looking frogs had evolved from their more salamander-like ancestors and were found around the world. No frog fossils have been found yet in local deposits, but frogs are known from rocks of similar age on every continent except Antarctica, so it is likely they were here, too. The lack of local fossils is probably due to the fact that amphibian bones are small and delicate, and this area has not been searched exhaustively by collectors looking for tiny fossils.
