Hoplophoneus is an extinct genus of the family Nimravidae, subfamily Nimravinae (false saber-tooths).
It was endemic to North America during the Late Eocene to Early Oligocene epochs (37-29 mya), existing for approximately 8 million years.
Hoplophoneus, though not a true cat, was similar to cats in outward appearance, though with a robust body and shorter legs.
The largest known specimen was examined for body mass and was estimated to have a weight of 160 kg (350 lb).
Hoplophoneus occidentalis was about the size of a large leopard and had canine teeth of only moderately-larger size.
The larger H. sicarius and H. mentalis had very large upper canines and a massive flange at the front of the lower jaw.
Hoplophoneus preyed on primitive horses such as Mesohippus, oreodonts, rhinoceroses, and other small mammals.
An adult specimen of Hoplophoneus discovered in Badlands National Park, South Dakota, in 2010, was found to have bite marks on its skull from the teeth of another adult individual of Hoplophoneus.
From examination of the wounds, it was found that the animal had been wounded by its rival's saber-teeth. Regrowth of bone around the injuries shows that the nimravid survived the attack.
Similar finds also reveal that such fights were likely commonplace among nimravids and that they would often aim for the back of the skulls and eyes of their opponents.
They went extinct around 29 million years ago. Cause of extinction is most likely climate change including change in prey species.
