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 63 mm (2.45 inches) across and consists of a single isolated complete head with nicely preserved arms and pinnules. These arms were used by the animal to capture particles of food, which were then passed to a mouth in the centre of the arms. Fossils with the arms preserved with this level of detail are hard to find. Complete isolated heads like these are rare and very hard to find. It was found in two pieces and was very thin and delicate, so has been backed with plaster and consolidated for stability. These crinoids are very sought after and not easy to find these days. A real one-off fossil.
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.
