An animal that lived 250 million years ago with an elephant-like tusk and a “turtle-like beak” is the oldest animal to hibernate to survive, a newly published study has found.
Research published in the scientific journal Communications Biology notes that Listrosaurus was able to slow down its metabolism by passing through a state of torpor (hibernation) based on fossil evidence.
Leading author of the study, Megan Whitney, said in a statement that “animals living near or near the poles were exposed to a more extreme environment present there.” “These preliminary findings suggest that entering a hibernation-like condition is not a relatively new type of adaptation. It is an ancient one.”

The 240-year-old ‘Megapredator’ has a 12-foot ripple in its stock.
The researchers looked at the cross-sections of six Listrosaurs in Antarctica and four in South Africa and compared them. They found similar growth patterns in dentin, but Antarctic people had “ga closely rings, ga thick rings,” which researchers believe was due to prolonged stress.
Whitney added, “The closest analogy we can find to the ‘stress marks’ we saw in the Antarctic Listrosorus tusk is the stress marks in teeth associated with hibernation in some modern animals.”
Lystros us juice can grow up to 8 feet long and the genus survived the event of extinction of the largest mass of the planet about 252 million years ago.

Researchers do not require 100% accurate listrosaurus true hibernation, as the signs of stress seen in Antarctic listrosaurs may be from another type of torper.
However, looking at their findings, the researchers believe that Listrosaurus is warm and that it has been closed for some time.
Whitney explained, “Cold-blooded animals often shut down their metabolism completely during the extreme season, but many endothermic or ‘warm’ animals that always hibernate reactivate their metabolism during their immaculate periods.” Observations close the pattern of small metabolic ‘reactivation events’ during periods of stress, similar to what we see today in warm-blooded hibernators. “
