he world’s only animal, past or present, with a complete 360-degree spiral of teeth was Helicoprion, which sliced into prey like a buzz saw.

This shark-like fish, which lived 270 million years ago, is described in the latest issue of Biology Letters. It had one of the most unusual mouths and sets of teeth in the animal kingdom.

"When the animal closed its mouth on prey, the spiral of sharp teeth rotated backwards, like a circular saw, and slashed through the meat,” lead author Leif Tapanila, an associate professor in the Department of Geosciences at Idaho State University, told Discovery News.

This animals teeth actually functioned in no different a way than a "Buzz Saw", worked. Like what some us might have in our garages.

Any thoughts?

Otherwise known as a circular saw...



A circular saw is a power-saw using a toothed or abrasive disc or blade to cut different materials using a rotary motion spinning around an arbor. A hole saw and ring saw also uses a rotary motion but are different from a circular saw. Circular saws may also be loosely used for the blade itself. Circular saws were invented in the late 18th century and were in common use in sawmills in the United States by the middle of the 19th century.

A circular saw is a tool for cutting many materials such as wood, masonry, plastic, or metal and may be hand-held or mounted to a machine. In woodworking the term "circular saw" refers specifically to the hand-held type and the table saw and chop saw are other common forms of circular saws. "Skilsaw" has become a generic trademark for conventional hand-held circular saws. Circular saw blades are specially designed for each particular material they are intended to cut and in cutting wood are specifically designed for making rip-cuts, cross-cuts, or a combination of both. Circular saws are commonly powered by electricity, but may be powered by a gasoline engine or a hydraulic motor which allows it to be fastened to heavy equipment, eliminating the need for a separate energy source.[1]

I knew that, I was just being sarcastic and denying ignorance.

Well golly gee, there are also hammerhead and saw tooth sharks out there. A whole toolbox of sharks.

This is why ATS is getting run down, this kinda stuff belongs on the shark week forums on the discovery channel for the people who never heard of such things.

This is nothing new at all.
This is all well known and in my opinion has no basis here on ATS. I often wonder why people leave? Now I know.

It is nice that you are a member of the ATS content police.

Golly gee, why does ATS even have a Fragile Earth forum or an Automotive forum.

If you don't like it, don't click on it, and you sure don't have to reply on people's threads being a complete ass hat.

I enjoyed the read and quite frankly, your type is part of the reason why ATS is the way is.

I enjoyed the read op.

The way that I understand a circular saw (from having cut things with them), they actually rotate 360 degrees.
This shark-like creature had a unique set of teeth, but they were more similar to a snail's shell than a circular saw blade. The teeth did not spin in the jaw 'like a buzz saw'.
It is still a theory that the tooth whorl even grew inside of the mouth.

This animal lived 270 million years ago. I doubt anymore than 1% of the membership has heard of it. Not all of us are marine biologists who specialize in prehistoric extinct sharks...

If anything, people are leaving because of rudeness, intolerance, uncivilized behavior and absolute ignorance... all of which were displayed prominently in your post.

I get that you're a grumpy old man, but, at least try to be funny, or witty or at least correct or at least a Little less ignorant and cynical (a terrible combination) when you accuse someone of ruining the whole website...

I dare you to do a poll thread to see who has already heard of this animal, and who has not.

I was wondering why Jude left... now I know. (joking, but right back atcha!)

To the OP, Thank you fkr bringing this to my attention!
This thing is unbelievable! I can hardly imagine seeing one of those today! The movie Jaws and sequels would have been great to include this beast! Unreal!

Yeah we've all seen those ones proob showed us... pfft! BORING.... But this thing is an absolute monster from my worst nightmares... My God, it literally saws you as it chews! I wonder what it needed those teeth to chew through...?

No it does not rotate 360 degrees (gimme a break...), yes it does saw you as it chews.
The upper part rotates while the lower jaw holds the prey in place, so there is a sawing motion, or grinding motion if you prefer.

Read this in the OP:

..... then give me a break.
The animal's teeth did not operate like that.

Yep, if I ever find myself back in time 270 million years, don't go swimming.


Cool article, scary to think what kind of beasts once roamed this earth!
