Robertson et al. (2004) highlight a burrowing habit as a likely survival
trait in the first hours of the Cenozoic, while Smith & Botha (2005) suggest
burrowing therapsids (as organisms adapted to dealing with periods of
dysoxia and hypercapnia) may have had a selective advantage over
non-burrowers at the P/Tr event.
