Description
This is a genuine fossil specimen of Peronoceras andraei, a striking ammonite species from the Upper Lias, dating to the Lower Jurassic period, approximately 180 million years ago. It was unearthed from the renowned fossil beds near Whitby, North Yorkshire, UK — a world-famous location on the Jurassic Coast known for yielding incredibly well-preserved ammonites and marine fossils.
Peronoceras andraei is recognised for its pronounced ribbing and robust shell structure, with spines or tubercles along its flanks — features that made it a formidable swimmer in ancient Jurassic seas. Ammonites were cephalopods, closely related to modern squids, cuttlefish, and octopuses. They thrived in the open marine environments of the Jurassic and evolved rapidly, making them ideal biostratigraphic indicators for geologists.
This particular specimen comes from the historic Alice Purnell Collection and has been expertly discovered by our team members Alister and Alison, then professionally cleaned, prepped, and treated by Alison. It represents a beautiful example of Yorkshire’s palaeontological heritage and would be a prized addition to any fossil collection or natural history display.
