A saber-tooth (alternatively spelled sabre-tooth) is any member of various extinct groups of predatory therapsids, predominantly carnivoran mammals, that are characterized by long, curved saber -shaped canine teeth which protruded from the mouth when closed. Saber-toothed mammals have been found almost worldwide from the ...

Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae (true cats). They were found in Asia, Africa, North America, South America, and Europe, with the earliest species known from the Middle Miocene, with the last surviving species (belonging to the genera Smilodon and Homotherium) becoming extinct around Late Pleistocene-Holocene transition (~13-10,000 years ago).

Extinctions in northern Eurasia were staggered over tens of thousands of years between 50,000 and 10,000 years ago, [2] while extinctions in the Americas were virtually simultaneous, spanning only 3000 years at most. [4][8] Overall, during the Late Pleistocene about 65% of all megafaunal species worldwide became extinct, [9] rising to 72% in ...
Arctodus is an extinct genus of short-faced bear that inhabited North America during the Pleistocene (~2.5 Mya until 12,800 years ago). There are two recognized species: the lesser short-faced bear (Arctodus pristinus) and the giant short-faced bear (Arctodus simus). Of these species, A. simus was larger, is known from more complete remains ...
