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 81 mm (3.2 inches) across, which is a good size for a single crinoid piece from this location, and consists of multiple stem sections with lovely detailed cirri on one side and a partial head with arms and pinnules on the other. It has a good level of detail but is water worn from its time in the sea. It is preserved in calcite with no pyrite and 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.
