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 118 mm (4.65 inches) across which is a very good size for a crinoid piece from this location. The fossil consists of a single partial head, preserved with great detail in the arms and pinnules. It is preserved in limestone with no pyrite. It has been coated with a soluble (removable) lacquer for protection. These crinoids are very sought after and not easy to find these days. This is a very fine example and the level of detail is uncommonly good to the smallest level.
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.
