Onchopristis
Onchopristis is an extinct genus of giant sawskate that lived during the Cretaceous of North Africa, Europe, and North America. It is probably the most well-known sclerorhynchoid.
Throughout the years, people thought Onchopristis was a ginormous sawfish. However, studies show that this is not the case. It is on the menu for the Spinosaurus.
Onchopristis was named by Ernst Stromer in 1917. Although the spelling "Onchopristis numidus" is commonly used, it is grammatically incorrect and the name of the species is literally Onchopristis numida.
The two species of Onchopristis are Onchopristis numida and Onchopristis dunklei.
Etymology change
Its name is derived from the Ancient Greek ónkos (ὄγκος, 'barb') and prístis (πρίστις, 'saw' or 'sawfish').
Description change
As mentioned earlier, Onchopristis was a large sawskate from the Cretaceous. This beast had a long rostrum with a few denticles. Its snout was used to impale prey or cut them do their death.
