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 72 mm (2.85 inches) across. The fossil consists of a partial head with nicely preserved arms and pinnules exposed along with two stems with attachment cirri. It has been coated with a soluble (removable) lacquer for protection. This one has a very high level of detail for its size. It is preserved in limestone with no pyrite. These crinoids are very sought after and not easy to find these days. This is a spectacular example of these bizarre fossils.
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.
