A nice 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 (1.72 inches) across and consists of two stem sections with detailed attachment cirri still in situ that had twisted around one another prior to fossilisation. This is a very unusual way for these fossils to be preserved. It is preserved with a very high level of detail in calcite in 3D with no pyrite. It has been coated in a thin reversible (soluble) lacquer for protection. A unique little fossil.
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.
