The skull of the oldest mammal has been found in southern Brazil. It is 22542 million years old and has the scientific name Brasilodon quadrangularis. When alive, it was a small shrew-like animal. It skimmed the environment during the time of the huge animals: the dinosaurs. To protect itself, it dug pipes and burrows into the ground.

Thanks to this ingenious maneuver, he survived the comet's invasion of Mexico. 95 percent of the animals then dropped the axe. Because of the extreme consequences that the comet's invasion caused on our planet, such as fire, air poisoning, covering the atmosphere with a thick cloud of comet remains, sulfur rains.

(yes, the animals that had survived were allowed to know it at the time). They died of hardship (or other causes that prevailed during that period after the raid)

At that time, the pointed mouse lived on whatever it could find. (It would never have been very picky) That's the second reason why it survived this fate, because the flora had also set at that time because the sun no longer rose through the cloud deck and could shine at the bottom. Most plants did not survive either. Only those with firm roots (such as those of the grass) such as ferns.

Did you know that the ferns were among the first plants that formed on the Earth on the soil that was still bare at that time?

Not so long ago, it was thought that the Morganucodon was the oldest mammal that hopped around during the dinosaurs. But its fossils are only 205 million years old.
