An assemblage of old bones
This is selection of old bones trawled up off the sea bed around Portland and assembled into a plesiosaur skeleton. Most of the vertebrae are in fact from ichthyosaurs but the limb bones are indeed those of a plesiosaur or pliosaur. Where is the head? Vertebrae are far more common than skulls for two reasons. Firstly, each animal had up to 180 vertebrae in its body but only one skull. Also, the skull is constructed from many delicate bones that easily break up.
