Helicoprion was basically just a ratfish with a weird thing in the back of its mouth. It didn't look nearly that weird.

I've read a hypothesis that heliocoprion's jaw shape is literally ideal for slashing through flesh the curved shape maximizes damage at the focal point of the curve. Heliocoprion lived at a time that coincided with the first fossilized giant squid remains. Giant squid are made entirely of flesh...

Those are some retardedly designed animals.

It's less retarded than the one directly below it. At least we have sharks that kill with their tail to make the guess somewhat grounded.

alex broadbent what are you doing
>>
>>2294029

I like the think it was more like purdy and parrish or richard ellis. with the teeth deeper in, maybe two spirals.

Karpinsky stuff just seems nonsense.

Another one i wonder about is them being horizontal in the mouth, kinda like alex broadbent, but with a shark. Mostly everything looks vertical.

The goofy lower outer jaw stuff, though, may be good for bottom feeding if the shark wants to dig through the bottom for food.

Sorry I'm confused. Are those all the possibilities of what the shark could look like? If so how do they even know the chainsaw belongs to them?
>>
>>2295476
Before we had the skull shown in >>2295406, lit all we had to go on for trying to imagine what the animal looked like was that central whorl of teeth. People guessed it was probably something shark-like based on the teeth and whatnot but that's as good as we could do.

All those pictures are what different researchers have proposed for the placement of the tooth whorl in something shark-like.
