Hildoceras bifrons Fossil Ammonite Upper Lias Lower Jurassic North Yorkshire, Runswick Bay Whitby

Original price was: £24.00.Current price is: £20.40.

This is a superb example of Hildoceras bifrons, a classic ammonite species from the Upper Lias of the Lower Jurassic period, approximately 180 million years old. This particular specimen was collected from Runswick Bay, near Whitby, North Yorkshire, a region celebrated worldwide for its exceptional ammonite preservation and historical fossil significance.

Hildoceras bifrons is named after St. Hilda of Whitby, and is characterised by its involute shell, fine ribbing, and a pronounced keel. These ammonites were fast-swimming, predatory marine cephalopods that thrived in the ancient Jurassic seas. Their presence in the fossil record offers insights into biostratigraphy and Jurassic marine ecosystems.

The geology of the region—specifically the Jet Rock and Grey Shales of the Whitby Mudstone Formation—provides perfect conditions for fossil preservation. The dark, finely laminated shales formed in anoxic seafloor environments, allowing exquisite fossilisation of marine life with minimal disturbance from scavengers or currents.

This fossil is part of the Alice Purnell Collection, a highly regarded British collection known for exceptional fossil quality and historical importance. It has been expertly cleaned and prepared to display the natural structure and aesthetics of this iconic ammonite.
