Description A Scissor-tooth shark, Edestus giganteus attacks an unsuspecting fish during the late Carboniferous. According to research by palaeontologist Wayne M. Itano of the species Edestus minor indicate that this genus of holocephalid fish might have hunted by vertically thrashing its prey, slicing it to pieces with its bizarre array of teeth. The animal would then devour its victim after dispatching it. The evidence for such a hunting style comes from tooth whorls from Edestus minor specimens in Texas, which show wear on the outermost teeth from impacting with the body parts of thick-skinned animals. What kind of thick-skinned creatures Edestus might have eaten is currently unknown. 

My portrayal of the newest theory on how Edestus might have hunted.

The way that Edestus gutted that fish. It was just so well-done.

I've always pondered over how Edestus hunted prey with its strange tooth arrangement. I'm glad I have at last discovered an image that depicts how it could have possibly have put those teeth to use.

Yeah. It seems to make the most sense that this was how it hunted.

I can concur with you on that.

I am guessing it couldn't retract it's jaws with this new hunting method.

Edestus could not retract its jaws at all. The oldest teeth were pushed outward as new ones grew in without being shed. that sketch is how the animal essentially might have looked.

Ooh thank you.  I thought it could retract similar to a goblin shark.

nope. protrusile jaws were something developed by more modern sharks, such as the goblin shark, which dates back to the cretaceous. a great many ancient sharks from the Palaeozoic had skulls with jaws fused at the front and back of their skulls.

Eugeneodontids like Edestus weren't even sharks

I know, but I still refer to them as sharks because of the high resemblance and the fact that rays hadn't evolved at that time. I use that term extensively when referring to Paleozoic chondrichthyes.
