Smilodon fatalis (pride of 3)
Smilodon fatalis ("the deadly knife-tooth") is possibly the best-known of the machairodontine saber-toothed cats. It appeared in North America about 1.6 million years ago and later migrated down the west coast of the continent to Peru. It became extinct around 10,000 years ago. This species is estimated to have ranged from 160 to 280 kg (350 to 620 lb). Particularly large specimens could weigh 350 kg. Their teeth are about 7 in. Although the saber-toothed cat has no close living relatives, paleontologists reconstruct how the saber-toothed cat looked by comparing its bones with those of large cats living today. Very powerful front legs and a short tail indicate that saber-toothed cats used stealth and ambush rather than speed to capture their prey. Recent investigations suggest that this saber-toothed cat probably used its long canines to slash through the throat, severing the wind pipe and cutting the jugular. Its teeth were surprisingly delicate and could easily snap off if a prey animal struggled. Its mouth could open up to 120 degrees, whereas its closest living relative, Panthera leo, or lion, can only open its jaws to 65 degrees.
Giant (Long-horned) Bison - Bison latifrons
Bison latifrons is an extinct species of bison that lived in North America during the Pleistocene. Also known as the giant bison, it reached a shoulder height of 2.5 metres (8.5 feet), and had horns that spanned over 2 metres (6.5 feet). The known dimensions of the species are much larger than either extant species of bison (it was approximately twice the body size) and other extant large bovids, and B. latifrons may be the largest bovid in the fossil record. B. latifrons reached a shoulder height of 2.5 meters (8.2 ft) and weighed over 2,000 kilograms (4,400 lb).
