Shark's head fossil. Fossilised head of a Jurassic shark (Hybodus sp.). The teeth of the shark can be clearly seen at centre left. These clutching-type teeth are typical of the Hybodus genus. The head shows many tiny black tooth-like projections known as denticles. These gave the shark's skin a coarse texture and served to protect the body of the shark. The Hybodus shark died out in the mass extinction that killed the dinosaurs 65 million years ago. This specimen is from the lower lias rock of Lyme Regis,England,which was laid down in the early Jurassic era (195-172 million years ago). It is part of the Martin Rigby collection | |
