Ichthyosaur Vertebra From Dorest, UK

This is a Ichthyosaur from the Jurassic aged Kimmeridge Clay, in England.

Ichthyosaurs ("Fish Lizard") was a giant marine reptile which thrived from much of the Mesozoic era. They evolved in the mid Triassic from a group of unidentified land reptiles which transition back into the water. This line evolved in parallel to the ancestors of todays dolphins and whales, something known as convergent evolution.

Belemnites were an extinct order of cephalopods (think shelled squid) that lived during the Mesozoic era.
