“The leg fossil, found at the Tanis site in North Dakota, belonged to a Thescelosaurus, a small herbivore, and is likely to have been ripped off after the asteroid hit and caused a flash flood.”
I’m having trouble picturing a flood ripping a leg out of an animal.
It’s more like a TRex had just cbomped down on this poor critter and a leg fell out of it’s mouth.
