Fossil of S. maximus

Scheenstia is an extinct genus of freshwater and marine ray-finned fish from the Upper Jurassic–Lower Cretaceous of Europe. The teeth of this genus are called "toadstones" and were believed to be found in the head of a toad. It is part of a family called the Lepidotidae in the order Lepisosteiformes. It is related to the much better-known Lepidotes.

Appearance[change]

A large fish, Scheenstia, could exceed one meter. It had a robust body and rounded teeth, perfect for squashing hard-bodied animals. It was probably a relatively slow swimmer. The body shape resembles the famous Lepidotes.
