FISH

Rhinocephalus planiceps

Skull of Eocene fish, Rhinocephalus planiceps, from Sheppey, Kent

Fish are generally covered in scales and have fins and a propulsive tail. There are several classes, Agnatha without jaws, the extinct Placodermi, modern Osteichthyes with a bone skeleton and Chondrichthyes with a cartilage skeleton.

The Eocene of Sheppey is famous for its fossil fish preserved in three dimensions like the skull of Rhinocephalus planiceps shown in the picture.
