The last 10 or 15 million years have given us some truly mega mammals, like mammoths, bears, cats, rhinos, and deer that were all much larger than their modern relatives.
Now a new species of saber-toothed cat has been described by paleontologists who found the ancient cat’s humerus bone among North American museum collections.
It turns out there is not one, but perhaps several other saber-toothed feline genetic branches, and
Machairodus lahayishupup would have been one of the largest felines to ever prowl the Earth. ....

Paleontologists have discovered a new species of saber-toothed cat in Oregon


According to a research paper published last week in the Journal of Mammalian Evolution, this new-found specimen provides clear evidence for a diverse range of predator fauna existing during the late Miocene of the continent that included some of the biggest felids in Earth s history.

The sabre-toothed cat was part of an early evolutionary branch that went extinct roughly 10,000 years ago, where today s house cats are an entirely different evolutionary offshoot that emerged later. Sabre-toothed cats, similar to lions, were quite social animals that hunted for their meals and existed amongst other members of the same species. ....

Newly Identified Species of Saber-Toothed Cat Was So Big It Hunted Rhinos in America


Using detailed fossil comparison techniques, scientists have been able to identify a giant new saber-toothed cat species,
Machairodus lahayishupup, which would have prowled around the open spaces of North America between 5 and 9 million years ago.
 
One of the biggest cats ever discovered,
M. lahayishupup is estimated in this new study to have a body mass of some 274 kilograms (604 pounds) or so, and possibly even bigger. It s an ancient relative of the well-known
Smilodon, the so-called saber-toothed tiger.
A total of seven 
M. lahayishupup fossil specimens, including upper arms and teeth, were analyzed and compared with other species to identify the new felid, with the fossils collected from museum collections in Oregon, Idaho, Texas, and California. ....
