Spotted hyena skull specimen, University of Wyoming Library
The spotted hyena was first officially described by German naturalist Johann Christian Polikap Erxler in 1777. The ancient Greek root of the scientific name of the spotted hyena was used by Pliny the Elder to describe an unknown animal in Ethiopia, possibly the hyena. In literature, it means' object in the color of saffron '. Although spotted hyenas have some similarities to the canidae family, they are more closely related to the civet family. Spotted hyenas belong to the cat suborder, so they are closer to the feline family than to the canine family. The spotted hyena is currently the largest member of the hyena family. It is believed that the ancestor of the spotted hyena branched out from the striped hyena during the Pliocene period (5.33-18 million years ago).

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.
