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 45 mm (1.78 inches) across, and consists of a detailed head with a arms coming from the calyx (head attachment plate) attached to a stem. It is preserved in calcite. These crinoids are very sought after and not easy to find these days, and small juvenile examples like this are very uncommon.
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.
