This is Scientific American's 60-second science. I'm Christopher in Taliatta.

Hundreds of millions of years ago, reptilian predators called Ictheosaurs swam the seas.

Their fossils look fearsome.

But paleobiologist Riosuke Motani of UC Davis says they may have looked more like friendly dolphins.

Maybe in life, ectheosos might have been cute, but at least the smaller ones.

Motani's team studied one such specimen found in southwest China.

It was 240 million years old, 15 feet long, but it seemed to have some extra bones in it,

which Motani's team determined to be the remains of a 13-foot-long

thaladosaur, or sea lizard, the Icthosaur had swallowed. And spoiler alert, the only reason

they were able to see this animal in the belly of the Icthiosaur is that this gigantic meal

never got digested. The Ictheosaur died soon after swallowing it. Motani was careful to say they're not sure exactly why the Ictheosaur perished,

but the specimen has a broken neck, so he gave a speculative play-by-play.

Perhaps he says the Ictheasaur snapped at the sea lizard, but the lizard fought back.

And the fighting between the two was fierce, probably.

So the Icthesor fought to subdue its prey, damaging its neck in the process.

Then it had to dislodge the prey's bony head and tail from its juicy midsection.

Now, the prey that had to do it through jerking and twisting, like the crocodiles do.
