A newly uncovered 300-million-year-old fossil might show a lizard shielding its offspring -- and could be the earliest evidence of animal parenting
Little is known about Paleozoic creatures' parental prowess. But a newly uncovered 300-million-year-old fossil might be the earliest evidence of a parent, well, acting like a parent.
Researchers from Carleton University in Ontario, Canada, discovered the partial skeleton of a lizard-like creature that had wrapped its tail around the skeleton of a smaller creature of the same species. Based on the"denning" position of the two and the difference in their sizes, the creature might've been a parent shielding its wee offspring -- a behavior widespread among mammals today.
