I believe there are a few cohabiting species around today. Seems like I’ve read that the Tutatara lizard and Kea bird of New Zealand will share a burrow.

"...the amphibian Broomistega and the mammal forerunner Thrinaxodon cohabited in a burrow"

Cohabited? Is there evidence that they were picking out furniture together? The article suggests that the crippled-up amphibian crawled into the burrow of a hibernating proto-mammal and then they were both killed. Proto-mammal could have been dead for years before the amphibian crawled in, so "cohabited" seems like a big assumption to me.

Maybe the mammal went out and caught the amphibian for food crushing its ribs. My speculation.

If I find a dead bird on the beach beside a dead carp, and I to marvel at the master of the skies who lived and died with the king of the deep? And was the warm-blooded bird trying to revive his cold friend by snuggling up to him?
