Group – Echinoderm
Age – Lower Jurassic, around 195 million years old

Crinoids or ‘sea lilies’ were not plants as their name suggests, but animals related to starfish and sea urchins. They have lived in our oceans for millions of years and can still be found today. They lived attached to the sea bed or to the underside of driftwood. The body consists of a long stem or stalk with the mouth, organs and five branching arms at the top. The arms are covered with small, sticky tube feet that the animal uses to catch tiny plants and animals (plankton) that drift along in the sea.

This picture shows the two most common types of crinoid fossil found at Charmouth (arm slab and the star-shaped stems) and a painting of what they would have looked like when alive in the Jurassic. Crinoids had a long stem which the animal used to attach to drift wood or the seafloor.
