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 95 mm (3.75 inches) across. The fossil consists of a multiple crinoid heads with a crowns of arms and pinnules as well as stems with long attachment cirri, all preserved in exquisite detail in 3D. There are also some stem ossicles that show the classic five-pointed star-shaped cross section that gives this genus its name. It is preserved in calcite with no pyrite and has been coated in a thin reversible (soluble) lacquer for protection. These crinoid heads are rare and not often offered for sale. This one has a huge amount of detail for its size. Several cracks in the fossil have been stabilised.
Around 196 million years old, 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.
