This phylloceras ammonite fossil is around 180 million years old, from the Lower Jurassic Period. It was excavated many years ago from the classic Posidonia Shale Deposit at Holzmaden in Wurttenburg, Germany. This ammonite exhibits the attractive golden colour of specimens from this locality, due to pyritisation of the shell imprint.
Whether as a gift, a striking ornament or a way to interest children in natural history, this Ammonite Fossil Plaque is a gift from a bygone era and a truly stunning fossil.
Cephalopods were marine, highly mobile swimmers, generally carnivorous. They achieved buoyancy by means of a chambered shell connected by a siphuncle
to exchange pressure of gas thus adjusting density.
