Is this lizard fossil evidence of animal parental care over 300 mya?

Tramping around Cape Breton looking for fossils:

Then Hebert spotted another set of bones that stopped him dead in his tracks: a tiny, inch-long skull, nestled into the space where a left femur met a pubic bone. This skull, Hebert realized, belonged to a juvenile, curled up against what was probably its mother.

Hebert didn’t know it at the time, but what he found would soon become the prime piece of evidence in a paper published today in the journal Nature Ecology & Evolution arguing that parental care—investing resources in offspring after birth—is at least 306 million years old…

“We tend to think of animals in [this part of] the past as ‘primitive’ or ‘simple,’” says Jackie Lungmus, a vertebrate paleontologist at the University of Chicago who wasn’t involved in the study. “But they deserve more credit. Even back then … these animals were probably doing a lot of the things that animals still do today.”

“Even back then … these animals were probably doing a lot of the things that animals still do today.” Right. So when did Big Evolution happen?

Lizards and snakes are some of my favorite animals, since they represent a couple of the few families of animals that can be oviparous or ovoviviparous. Something of a challenge for big evolution, no? drc466
