Dinosaurs that may have hibernated

In connection with the theme of \"hibernation\", I created \"dinosaurs that may have survived hibernation\" that have recently appeared. It\'s more like a crocodile or lizard-like reptile than a dinosaur, though... While the northern continent was severely damaged by the meteorite impact, some types of dinosaurs on the southern continent survived for a while, and the same bird species (*dinosaurs = birds is the accepted theory these days). Recently, there has been a theory that some birds may hibernate through winter, suggesting that they may have survived the period of cooling caused by dust kicked up by meteorites.
