8.3" Jurassic Ammonite (Harpoceras) Fossil - Germany

This is a 8.3" wide ammonite of the genus Harpoceras, collected from the Posidonia Shale of Germany. It has been compressed and is preserved on a black shale in a partially pyritized state. The ammonite is perfectly centered on an 11.2 x 8.9" slab of shale. Comes with an acrylic/metal display stand.

The Posidonia Shale (part of the Sachrang Formation) outcrops near the town of Holzmaden in southern Germany have been commercially quarried for centuries. The quarried shale has been used for such things as tile, table tops, and fireplace hearths. These quarrying operations have also uncovered a vast treasure trove of beautifully preserved, Early Jurassic (~183 million years old) fossils. The lower shale layers have even produced world-class ichthyosaur fossils with preserved skin and soft tissue impressions.
