英文回答：
Saber-Toothed Cats.
Saber-toothed cats were a diverse group of extinct feliforms that lived during the Cenozoic Era. They are characterized by their long, curved upper canine teeth, which were used to pierce the flesh of their prey. Saber-toothed cats were primarily carnivores, and their diet consisted of large herbivores such as deer, antelope, and horses.
The earliest known saber-toothed cats appeared in the fossil record about 42 million years ago. They quickly diversified and spread throughout the world, becoming one
of the most successful groups of predators during the Cenozoic Era. Saber-toothed cats reached their peak
diversity during the late Miocene and early Pliocene epochs, but they began to decline in numbers during the late
Pliocene and Pleistocene epochs. The last known saber-toothed cats died out about 10,000 years ago.
Saber-toothed cats were once thought to be closely related to modern lions and tigers, but recent research has shown that they are more closely related to the caracal and serval. Saber-toothed cats were typically larger than modern big cats, and they had more robust bodies. They also had shorter tails and longer legs.
The saber-toothed cats' distinctive canine teeth were their most striking feature. These teeth were up to 12 inches long, and they were used to deliver a powerful bite. Saber-toothed cats used their canines to pierce the flesh of their prey, and they would then use their sharp claws to hold the prey down while they ate.
Saber-toothed cats were ambush predators, and they would often lie in wait for their prey before attacking. They were also capable of running down their prey over short distances. Saber-toothed cats were solitary animals, and they lived in a wide range of habitats, including
forests, grasslands, and savannas.
The extinction of the saber-toothed cats is still a mystery. Some researchers believe that they were outcompeted by modern lions and tigers, while others
believe that they were unable to adapt to the changing climate. Whatever the cause, the extinction of the saber-toothed cats was a major loss to the ecosystem.
