A stunning example of a crinoid fossil of the species Pentacrinites fossilis from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The fossil measures 48 mm (1.88 inches) across. The fossil consists of a partial head with nicely preserved arms and pinnules. It has been coated with a soluble (removable) lacquer for protection and it has been backed with plaster to make it solid and stable. These crinoids are very sought after and not easy to find these days.
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
Crinoids are echinoderms closely related to starfish and sea urchins, and have been around for many hundreds of millions of years. They still live today in the deep seas around the world.
