Description
2 Fossil Bony Fish with Leaf - on original matrix - Green River, Wyoming - Diplomystus dentatus & Knightia
Eocene - U.S.

A Diplomystus dentatus fish plus a Knightia, Green River Formation, Wyoming, USA.
In addition the plate has a really well preserved leaf.
The fossil is 50 million years old, from the Eocene Period.

Diplomystus was a surface feeder as can be seen from the upturned mouth, and they preyed on smaller fish such as the Knightia

50 million years ago a lake existed in what is now Wyoming, with a size of around 930 square miles. The unusual chemistry of the lake prevented decay and the scavenging of the dead organisms, while thin layers of alternating limestone and organic matter slowly accumulated.

A super display fossil plate which is wooden backed ready to hang.

Plate Size: 43 cm x 26 cm, Fish 13 cm & 8.5 cm long, & Leaf 17.5 cm long.
Weight: 2.5 kg
