Re: Hibernating Dinosaurs?

Hibernation is one of the main proposed mechanisms
for mammal survival at the K/T.

Aha... interesting.

So, obviously, since no non-avian dinosaurs
survived, none could have hibernated!

I have trouble imagining animals above the size of a bear hibernating... as for smaller ones, hibernation obviously wouldn't have been enough to survive the catastrophe _and_ its aftermath.

What's the current opinion about the idea
of hibernating dinosaurs from Australia/Antarctica?

It seems there isn't much of an opinion.

The only thing I can find is mention of a possible
hibernating ornithomimid,

Is that based on "growth rings" (lines of arrested growth, LAGs)? Those same rings can be found in the bones of farm alligators...
