Re: Hibernating Dinosaurs?
I have to admit to a hidden agenda when I asked the question. I have a
"beef" with Horner's claim that _T. rex_ had enlarged olfactory lobes.
Enlarged compared to what? Or is the relative size of _T. rex_'s
olfactory lobes actually typical for coelurosaurs? For all we know,
their relative size may be typical for theropods in general.
Hence my question about _Leaellynasaura_.
