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 100 mm (3.9 inches) across, which is big for a crinoid fossil from this location. The fossil consists of multiple heads with detailed arms and pinnules, including a head preserved flattened down from above, giving a rare view into the centre of the calyx. The arms radiate out from the centre of the calyx in a beautiful fashion. The level of detail on this example is exceptional, right down to the micro level. It was found in multiple pieces and has been repaired back together, as is standard for these fossils due to the way they come out of the cliffs. It has been coated in a thin, reversible (soluble) lacquer for protection. This is a very fine example of this fossil type.
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.
