Fossil specimen of saber toothed tiger skeleton at Vienna Natural History Museum

The saber toothed tiger is a carnivorous mammal belonging to the genus saber toothed tiger in the order Felidae. The saber toothed tiger was once widely distributed on the continents of Asia, Europe, and America. It appeared in the Oligocene 35 million years ago and became extinct in the Pleistocene one million years ago. Their living period was during the Quaternary glacial period, when herbivores were slow-moving and easily hunted. But the ice age has ended, and cold resistant large herbivores cannot adapt to climate change and migrate northward, dying due to insufficient food. The saber toothed tiger lost its food source, did not have an advantage in hunting, and even became a prey for humans. In the end, it could only go extinct with the extinction of large thick skinned animals.
