Knightia and Diplomystus, the most prevalent fish in the Green River Formation, offers a captivating glimpse into the Eocene epoch of the Rocky Mountains. The impeccable preservation of these fish in limestone, often attributed to sudden ash falls from volcanic eruptions, makes them a remarkable relic of ancient aquatic life.

While
Knightia were a primary diet for larger fish like Diplomystus, they themselves thrived on algae and plankton, positioning them as secondary consumers in the aquatic food chain of their time.

The hue of these limestone fossils varies based on the stone layer they originate from. Their spectrum ranges from light brown to an almost black shade. Interestingly, the lighter brown fossils often reveal more intricate details, making each piece a unique testament to nature's ancient artistry.

Individual specimens vary but your item will resemble the pictured examples.

    My 7-year-old and I loved this fossil. It was even better after watching the YouTube video episode from the Evolution Store, devoted to Knightia fish. Thank you!
