Hildoceras bifrons Ammonite Fossil


A few posts ago, I wrote about the snakestone ammonite. This ammonite is associated with St. Hilda of Whitby, Yorkshire, England. The American palaeontologist Alpheus Hyatt (1838-1902) named an ammonite genus Hildoceras after her.

Above is an image of an Hildoceras bifrons (Bruguière) ammonite fossil. It dates to the Jurassic Period (Toarcien) and was found in Newcastle, England. Specimen was under glass in a room with a lot of natural light so there is glare on the upper part of the fossil.

Fossil displayed at Muséum National D'Historie Paris, France on August 2016.
