It happens that fantasy predict the future, but it turned out that the multipliers have guessed the past. Recently, paleontologists dug up a mammal that lived in the dinosaur era — 95 million years ago — that had a skull 2 centimeters long, big eyes, a thin long nose, and a couple of long sharp canines.
In general, mammals existed in the Mesozoic era, but they are found very rarely. Many of them have no modern descendants, including the saber-toothed protein, called Cronopio . Judging by the size of the eyes, the creature was nocturnal, but the purpose of the canines remains a mystery - not a single modern mammal has anything like it.
