Re: Burrowing/hibernating mammals have lower extinction risk

There don't seem to have been many Mesozoic mammals that *didn't* fit into the
category. Unless that's a function of preservation (dying in a collapsed
burrow buries your corpse
quickly, with little chance of scavenger disturbance).
Certainly it doesn't seem to have applied to birds. I have a hard time
ratites, and even if most post-K/Pg volant birds were like sheer-waters or
puffins, those species
only tend to nest in burrows for part of the year rather than live in them
