Smilodon was a genus of saber-toothed cat. There were three species.[1] Smilodon gracilis (or S. fragilis) was the ancestral, smaller, species (2.5 to 0.5 million years ago).
Smilodon populator (1 mya to 10 kya) was a large, heavy species from eastern South America. It was 1.2 m high at the shoulder, 2.1 m (83 in) long on average. With an estimated weight of 220 to 400 kg, it was among the heaviest known felids.[2] Its upper canines reached 28 cm (11 in) and protruded up to 17 cm (6.7 in) out of the upper jaw.
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.[3] 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.[4] It was about 1 metre tall at the shoulders.
