Helicoprion is a genus of extinct shark-like [1] eugeneodont fish. Almost all fossil specimens are of spirally arranged clusters of the individuals' teeth, called "tooth whorls", which in life were embedded in the lower jaw. As with most extinct cartilaginous fish, the skeleton is mostly unknown.
Dunkleosteus is an extinct genus of large arthrodire ("jointed-neck") fish that existed during the Late Devonian period, about 382–358 million years ago.It was a pelagic fish inhabiting open waters, and one of the first vertebrate apex predators of any ecosystem.
Using three tests, researchers determined that the 780,000-year-old bones indicated that humans cooked fish before eating it, according to the study. This marks the earliest evidence that hominins ...
Members of the Eugeneodontiformes are further classified into different families, the most well-preserved members that have been discovered are commonly placed within the families Helicoprionidae ("spiral saws"), and Edestidae ("those which devour"), the former containing the genera Helicoprion, Sarcoprion, and Parahelicoprion, and the latter ...

The study of prehistoric fish is called paleoichthyology.

Onchopristis is an extinct genus of sclerorhynchoid from the Cretaceous of North Africa, Europe, North America, and potentially South America.It contains two valid species, O. numida and O. dunklei, though some researchers argue that both may be considered a single taxon with variation in morphology caused by a wide geographical range.
