A stunning example of an ichthyosaur coprolite fossil from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.
The coprolite measures 33 mm (1.3 inches) across. It represents the poo of an ichthyosaur (or possibly a large fish) and includes remains of the diet of the animal. It has a nice light brown colour and shows good detail in the texture on the surface of the coprolite, which is often lost in specimens that have been exposed to the erosive action of the sea. This specimen is not worn down like others and is in great condition. There are some unusual large plate-like calcite crystals on the surface of the coprolite. These iconic fossils made Lyme Regis and the Jurassic Coast famous. They were first found by pioneering Victorian fossils hunters like Mary Anning. Material like this from the Jurassic Coast is very sought after.
Around 198 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
