Have animals been able to hibernate since 250 million years ago?

A study of fossil tusk layers from Antartica suggests that a very widespread species resorted to hibernation back then:

Scientists discovered the hibernation-like state in a member of the genus Lystrosaurus, a distant relative of mammals. The stubby, pig-like animal first emerged in the fossil record not long before the end of the Permian Period, which was marked by a mass extinction event that wiped out 70 percent of land-based vertebrates…

Scientists were able to the discover the animal’s hibernation by studying its tusks, the cross sections of which contain records of metabolism, growth and stress.

    Huh? Was hibernation a meme or trend, spread by Influencer Bears? Did trees learn how to drop their leaves in the fall by watching other high-status trees?

    Seasonal behaviors have to be innate. They couldn’t have started after the bears were already living in the arctic.

    Per ‘RCCF’ ‘250M’ calibrates to about before and during 1656 anno mundi
    as the Mabul impacts year began by the original single continent and ended by the abrupt onset of The ice ages. So the fossil evidence from ‘250M YA’ deep-time dependent assumption consensus, we have, was mostly formed during the Mabul from what was mostly living until, the Mabul aka global flood by Noach.
