An extremely rare aspiration fossil (fish eating another fish) featuring a large Mioplosus eating another fish. 
 
Aspiration fossils are amongst the least discovered types of fossils found in the Green River Formation of Wyoming and this is no exception. It features a mioplosus eating a smaller fish. The smaller fish is most likely a knightia or diplomystus. It is remarkable that such a dynamic ecological event was frozen in time for us to see here.
 
The larger fish known as Mioplosus (measuring 11" on this fossil plate) is believed to have been a predator due to its numerous pointed teeth and fossil record. Both aspiration as well as fossils with smaller fish and other belly contents have been found in the Green River Formation. Mioplosus were also commonly found by themselves and not in large groups elluding to the fact that they may have been solitary hunters. They are idnetified by long skinny bodies and double dorsal fins. This specimen has great bone, scale and skin presercation both seen and felt when holding the fossil. Close ups of the open mouth and aspiration show nice detail of the smaller fish being eaten. 
 
**Center of fish shows a slight white spot which is a glare off of one of the bony structures as seen in the close up pictures. This is not a flaw in the fossil as it may appear in the photos but rather a glare from the camera flash**
 
*Fossil plate measures 16" by 12" with the mioplpsus measuring 11". It is backed with 3/4" cabinet grade plywood and ready to hang in the home or office.
