Barbourofelis is an extinct genus of large, mostly carnivorous mammals of the family Barbourofelidae (false saber-tooth cats) endemic to North America, during the Miocene to Pleistocene living from 5.3–0.011 million years ago and existed for approximately.
Barbourofelis is a saber-toothed cat, making it a separate species (Barbourofelidae ) with remarkably similar to members of the cat family (Felidae), which are distantly related. Barburofelis first appeared about 18 million years ago during the Miocene to Pleistocene and are widely distributed in Africa, Eurasia and North America. The most famous native is actually the barburofelid Barbourofelis. This race has existed for about 9 million years, appearing 15 million years ago and became extinct around 6 million years ago. Barburofelis were the largest and most sophisticated predators of this family.
The largest species known as Barbourofelis fricki was living in North America, having reached the size of a modern lion, but has superior in weight, due to its unusually strong physique. Barburofelis lovei was the size of a jaguar. The skull of Barburofelis was shortened to a greater degree than in kind of saber-toothed cats Smilodon, and hypertrophied upper canines were perhaps even more advanced. The lower jaw, as well as saber-toothed predators have all been relatively weak, the lower teeth are not large, the set of teeth is shortened. On the lower jaw bone, there were specific processes that are characteristic for the early saber-toothed cats, but more pronounced than in the past. A very interesting structure of the rear limb girdle of Barburofelis. The pelvis of the predator was more extended than that of the cat with more developed iliac bones, which may suggest that barburofelis was more stable, rising on the feet and striking the front, as is often done in modern cats.
The structure of the shank is also different from that of other cats; it is wider and more closely resembles the structure of the family Mustelidae metatarsus or coonskin, i.e barburofelis was polustopohodyaschim, although mostly moved relying only on his fingers, like cats, dogs and other carnivores. Barburofelis's tail was much longer than that of Smilodon, but shorter than today's lions and tigers. A single specimen was examined by Legendre and Roth for body mass. The first specimen was estimated to weigh 66.4 kg (150 lb). Thought to possibly be lion-sized and had the longest canines of all barbourofelids. They had very prominent flanges on the lower jaws and an unusually shaped skull. The barbourofelids were probably very muscular, resembling a bear-like lion or lion-like bear. Although the nimravid family did evolve into cat-like forms, they left no descendents among modern cats.
