Saber-toothed tigers include only members of the subfamily Saber-toothed tigers of the cat family, while other saber-toothed hunters only resemble saber-toothed tigers and are not taxonomically congenial. Before the emergence of the legitimate saber-toothed tiger, there was also a class of saber-toothed carnivores that looked like them that were widely distributed on various continents, and they were pseudo-saber-toothed tigers, including the dinosaur cat, the saber-toothed tiger and the ancestral hunting tiger. By the early Miocene, 15 million years ago, most of the pseudoscephalus had become extinct, but it was at this time that the Babo saber-toothed tiger, the top saber-toothed tiger that was more terrifying than them, began to sweep across Eurasia and North America. Several of them are only the size of leopards, while the late Frekibabo saber-toothed tiger is almost as large as the largest African lion.
The Frekibabo saber-toothed tiger is not only the largest non-cat saber-toothed animal in history, but also the first to be discovered. The Babo saber-toothed tiger is large and thick, and its muscles are unusually developed, especially the forelimbs are very powerful. Their eyes grow on either side of the head rather than near the front, most likely to make it easier to use saber teeth and reduce the pressure on their faces when their mouths are wide open. Its saber teeth are flattened and long machete-like, with sharp edges, up to 22 cm long, and are almost the most developed of all saber-toothed animals; the lower jaw, although derived from the huge leaf guard, can only cover half of the saber teeth.
The Gbagbo saber-toothed tiger was one of the most ferocious land carnivores on Earth at the time. However, they are strong and powerful but not good at running, and may use their forelimbs to pounce on and suppress the prey when hunting, and then use their saber teeth to complete the deadly attack. However, their long, curved saber teeth are easily crushed by bones or trapped in deep flesh and are difficult to pull out, so it is now generally believed that Saber-toothed tigers such as Babo saber-toothed tigers and saber-toothed tigers, bag saber-toothed tigers and blade-toothed tigers mainly use saber teeth for cutting rather than piercing, cutting the throat of prey like a dagger.
Due to the excessive specialization of the body, the difficulty of adapting to the changing environment, coupled with the emergence of the feline saber-toothed tiger, the Gbagbo saber-toothed tiger disappeared in the Pliocene 6 million years ago. Their disappearance means that the cat hunting family has since completely withdrawn from the stage of history.
