Toothy Spiral Jaw Gave Ancient Sea Predator an Edge

...went extinct some 225 million years ago.


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

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.

Wouldn’t have made it a day past 230 million without the ol’ Makita Mouth.

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