I agree with you relative to crocs (I hesitate to claim this was likely a
widely used practice among dinosaurs). However, if some
percentage of tropical dinosaurs used this
strategy, and zero percentage of mammals (because either they were
viviparous or had better ways of concealing their eggs, i.e., they were
small), the "hibernation" card is more likely to favor dinos than mammals.  

Or maybe all the tropical mammals bit it, and all the Paleocene survivors are descended from hyperborean (or hyperaustran) species that could already hibernate.  Who knows?
