This is a magnificent fossil fish specimen. In this unique piece, a gorgeous, large Diplomystus dentatus (18" long) is preserved with small fish (Priscacara liops) in its stomach. 

Very rarely do you see such a clear example of this occurrence. And, furthermore, the scales (but not ribs) of the large fish have been carefully removed so that the stomach contents are more visible. 

It's truly remarkable that this dynamic ecological event was frozen in time for millions of years!

Diplomystus is an extinct genus of herring. Its distinctive upturned mouth was well suited to nab small surface fish.

These fish swam in ancient Eocene lakes in Wyoming, USA, 50 million years ago. They were discovered in the famous Green River Formation, which is known to produce some of the most spectacular vertebrate fossils in the world.

Hours of painstaking work by a professional fossil preparator was needed to uncover the fine bones of this fossil from the stone.

The slab of stone measures 23 1/4” x 13”. Large fish measures 18 inches long.

Slab has a plywood backing.
