hemipristis

Hemipristis serra, often dubbed the "Wolverine Shark", was a formidable predator that roamed the ancient seas during the Miocene epoch. It was a distant relative of the modern-day Snaggletooth shark but was significantly larger and more fearsome.  

Its most distinctive feature was its impressive array of serrated teeth. These teeth, with their unique saw-like edges, were perfectly adapted for slicing through flesh and bone. This powerful bite allowed Hemipristis serra to prey on a variety of marine animals, including large fish, marine mammals, and even other sharks.

While the exact size of Hemipristis serra is still debated, it is estimated to have reached lengths of up to 20 feet.
