description Edestus Overview

Edestus is an extinct genus of eugeneodontid holocephalan fish that lived during the Late Carboniferous period, with fossils found in regions including the United States, Russia, and the United Kingdom. The genus is distinguished by its unique tooth whorls, which projected outward from its jaws and functioned much like a pair of pinking shears or scissors. Unlike modern sharks, its teeth did not fall out but instead remained attached at the jaw's front edge, creating a highly specialized mechanism for capturing or processing prey.

help Edestus FAQ

What kind of prehistoric creature is Edestus?

Edestus is an extinct genus of cartilaginous fish that lived during the Late Carboniferous period. It belongs to an order of bizarre, ancient sharks known as eugeneodonts.

Where have Edestus fossils been found?

Fossils of Edestus have been discovered in the United States, Russia, and the United Kingdom. Most of these remains consist solely of their distinctive teeth, as their skeletons were made of cartilage that rarely fossilizes.

Why is Edestus often called the "scissor-tooth shark"?

It earned this nickname because of its terrifying, scissor-like tooth blades that protruded from its mouth. Unlike modern sharks, Edestus did not shed its teeth, meaning its gums grew continuously outward, pushing older teeth forward.

What did Edestus eat?

While its exact diet is debated, scientists believe it fed on other fish and marine animals. Its unique tooth structure suggests it may have used its jaws like a shear or saw to incapacitate its prey.
