Ammonite Plaque - Dactylioceras sp.

The Science

The Ammonites in these plaques are from the Dactylioceras sp. They were found in Germany. They are estimated to be approximately 180 million years old, which places them in the Jurassic Period.

The Story

These Ammonites were widespread and their name comes from their straight, finger-like ribs. Mass mortalities of this species has been found, indicating perhaps that they traveled to a certain place to spawn and then immediately died. Each plaque contains multiple golden ammonites, set into a dramatic black matrix.
