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 53 mm (2.1 inches) across and consists of a stem section with lovely long and detailed cirri still attached to it. The reverse of the fossil has some stem ossicles that show the classic five-pointed-star-shaped cross section that gives this genus its name. It has a good level of detail and is preserved in calcite with no pyrite. It has been coated with a soluble (removable) lacquer for protection.
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.
