Golden Pyratised Ammonite (Dactylioceras) - Whitby, UK

A Jurassic fossil ammonite (Dactylioceras) from Whitby, England. This ammonite, and the small and partial ammonites in the surrouding rock, have a beauitful golden colouration due to being partially replaced by iron pyrite.

Ammonites were marine creatures that lived millions of years ago, during the Paleozoic and Mesozoic Eras. They were distant relatives of modern-day octopuses and squids, and their fossilized shells are often found in sedimentary rocks.  Ammonites had coiled shells that were often beautifully patterned. These shells were made of calcium carbonate, just like the shells of snails and clams. The shape and details of their shells can help scientists determine the age of the rock they are found in, making them valuable tools for geologists.

The ammonite comes with a display stand, as pictured, and a label featuring the specimen name, place it was found and age.

This is genuine fossil. All the specimens we offer come with a lifetime authenticity guarantee.
