Fossil echinoderm collection

Pentacrinites fossilis, a Lower Jurassic crinoid from Lyme Regis, Dorset
The diversity and abundance of echinoderm fossils are reflected in the large, world-class collection that we care for.
Fossil echinoderms are numerous, due in part to the fantastic preservation potential of the calcite plates that form their skeletons. They have been found in Phanerozoic marine sediments around the globe.
