Re: Dinosaurs burrowed to keep warm
(Deliberately to the list this time.)

It occured to me that at least some folks think that one reason that
mammals made it thru the K/T event was that they burrowed and were kept
free of the fires, etc that would be part of the astroid collision. It was
thus assumed that dinos did not have this activity. Yet here we are
commenting of just this activity.
Burrowing certainly helped, but it certainly wasn't enough. Ornithopods look
like they depended on green plant parts and were not able to subsist on
seeds and the like. When fire, acid rain, and whatnot have killed all green
plant parts, we expect the ornithopods to die out.
