Toothy Spiral Jaw Gave Ancient Sea Predator an Edge
LiveScience ^ | February 27, 2013 | Stephanie Pappas

An ancient sea predator had a spiraling whorl of teeth that acted as a lethal slicing tool, according to new scans of a mysterious fossil.

Helicoprion was a bizarre creature that went extinct some 225 million years ago.

I’m really glad I live today, when humans are at the top of the food chain.

“.....went extinct some 225 million years ago.”

I think it was because of the funny looking jaw.

I’m having a hard time reconciling those two statements.

Why would a FISH that lives IN WATER, need to get on a BOAT that goes ABOVE water??????

Maybe Noah also gave fish bycycles to ride around on the poop deck of the U.S.S. Ark.....

Now there's a critter with terminal underbite! He's desperately in need of some chinodontic equipment!

Meh. Non-surfing humans would have been then too.

99% of species have gone extinct. If if got near to the top of the food chain and held on for a respectable span, it can be counted as a success. The analogy is a bull rider. An eight second ride is pretty darn good.

My thoughts exactly. In fact, to take it a step farther ... if evolution “works”, then first you have to reconcile how the mutation occurred in the first place. Supposedly this mutation made life better for progeny, yet they went extinct. If life was getting tougher generation by generation, per evolution, this should have bred OUT of the species. To reach a point of collapse of ANY species is an argument of failure for evolution. I love how this article ends by saying how this awesome killing machine probably lived on squid .... and that makes sense ... there would be NO leverage on a jaw like that to rip or tear anything of substance ... in fact it would be just the opposite. Take on anything with a thick skin and it could snap your jaw off if it swam away.

Toothy spiral jaws aren't very effective against comet impacts.

Perhaps it went extinct because the jaw DID NOT give it an advantage.

If mutations occur and some result in positive adaptations for a species, then it is logical that other mutations cause negatives for a species.

I’m of the school of thinking that believes giraffes did not get taller at 1mm every 1000 years in order to better survive. They got taller and found a way to deal with it, that did not result in the end of the species.

The problem with evolutionary biologists is that they first reject a creator and then to decide that all evolutionary changes must have some “devine” purpose. They can’t have it both ways.

Evolution by mutation isn’t perfection by design, its happy accidents and getting by with what you got.

Who is to say that some species descended from this beast did not survive and have that strange spiral jaw trait evolved out of it?

99% of all species ever discovered are currently extinct. It doesn't mean that they were failures, or failures waiting to happen. Some existed and dominated their niche for millions of years.

“The only known fossils of this animal are the teeth, which were arranged in a fantastic “tooth-whorl” strongly reminiscent of a circular saw. It was not until the discovery of the skull of a related genus of shark, Ornithoprion, that it was realized that the tooth-whorl was in the lower jaw.”

So, once again, these are just-so stories from the evolutionists, assembled out of 1% evidence and 99% imagination.
