This Thursius fish is nearly complete, missing only the head. The fins, scales, and overall body are in beautiful condition. The scales are coated in a sheen of pyrite, which gives them a brassy look under certain lights.
Thursius would have been a mid-range predator in its environment, preying on smaller animals but likely being eaten by larger fish. Thursius belonged to a group of fish called the sarcoptergian, or lobe finned fish. This is the group of fish that ultimately gave rise to amphibians and other tetrapod animals. The difference between a ray-finned fish (most modern fish) and lobe-finned fish is that the lobe finned fish have bones further down in their limbs, allowing for a primitive elbow-wrist system. While this structure would not have allowed Thursius to walk on land, it could have propped itself up on a river or lake bottom.
Lobe finned fish are not terribly common today, though a few types, such as lungfish and coelocanths still exist.
