Smilodon
Smilodon fatalis (or S. californicus; 1.6 mya to 10,000 years ago) was the famous cat known from the Rancho La Brea tar pits in Los Angeles. The tar, a bit like asphalt, has yielded about a million bones of late Pleistocene mammals, of which 162,000 bones are from Smilodon, representing perhaps 1200 individuals. The cat was about the size of a female lion, but weighed more, perhaps 200 kg. It was about 1 metre tall at the shoulders.
