smilodon gracilis
Smilodon ( /ˈsmaɪlədɒn/), often called a saber-toothed cat or incorrectly a saber-toothed tiger, is an extinct genus of machairodonts. This saber-toothed cat was endemic to North America and South America, living from near the beginning through the very end of the Pleistocene epoch (2.5 mya—10,000 years ago). The nickname "saber-tooth" refers to the extreme length of their maxillary canines. Despite the colloquial name "saber-toothed tiger", Smilodon is not a tiger; the latter belongs to subfamily Pantherinae, whereas Smilodon belongs to subfamily Machairodontinae. The name Smilodon comes from Greek: σμίλη, (smilē), "chisel" + ὀδoύς (hodoús), "tooth", or in the genitive: ὀδoύς, ὀδόντος, odóntos. Smilodon gracilis, 2.5 million-500,000 years ago; the smallest and earliest species (estimated to have been only 55 to 100 kg (120 to 220 lb) was the successor of Megantereon in North America, from which it probably evolved. The other Smilodon species probably derived from this species.
cougar
The cougar, which is also commonly referred to as a puma, mountain lion or panther, is the second largest cat in North America. Unlike other big cats, however, the cougar cannot roar. Instead, the large feline purrs like a house cat.
Cougars also have similar body types to house cats, only on a larger scale. They have slender bodies and round heads with pointed ears. They vary between 1.5-2.7 m (5-9 ft.) from head to tail. While males can weigh up to 68 kg (150 lb.), females weigh less, topping out at nearly 45 kg (100 lb.).
The coat of the cougar is a grayish tan to reddish color with lighter parts on the underside. The tail has a black spot on the end.
Inhabiting various ecosystems from mountains to deserts to sea-level, the cougar’s established range includes western North America, a small region in Florida, and most of South America. They make their home anywhere that there is shelter and prey. they have no predators but anacondas , jaguars , bears and packs of wolves give them competition.
Generally they prey on deer but also feed on smaller animals if necessary, including domestic animals and livestock. Cougars have even been known to eat insects. Skilled and cunning hunters, cougars stay hidden from their prey until they can pounce with claws out-stretched. Cougars can also climb with ease and leap over 6 m (20 ft.). After killing a large animal, a cougar hides the carcass and eats in the coming days.
