[soo' dA lor' us] ancestor of today's
Approximately twelve species of Pseudaelurus
once roamed the plains of Eurasia, Africa, and
North America between 20 and 8 million years ago.
All of them looked much like modern cats except
for having shorter "hand" and
"foot" bones, hind limbs longer than
forelimbs, and a long, flexible back. The
smallest species was about the size of a modern
house cat, the largest about the size of a modern
(about 5 feet long and 50 pounds).
The first cat to immigrate into the Americas
(which it did via the land bridge across the
Bering Sea during the early Miocene), Pseudaelurus
gave rise to the saber-toothed cats known as Smilodon. It is
also believed to be the ancestor of all modern
cats, including the domestic house cat.
Pseudaelurus ("false cat")
was named by French zoologist Paul Gervais in
1850, who based the designation on a single
mandible that had been described over a decade
earlier by another Frenchman, Edouard Lartet, who
thought it resembled that of the modern hyena.
