At least 67 species of sabertoothed cats existed in North America between 42 million and 11 thousand years ago before going extinct.
Their disappearance can be attributed to both the changing climate at the end of the Ice Age and the appearance of humans in the Americas.
Though there are single jaguars now living within Arizona,[2] the species has largely been extirpated from the United States (in the states of Texas, Colorado, New Mexico, and Louisiana) since the early 20th century; although it is found throughout most of South America, its territorial limit being lands further south than northern Argentina.
The ocelot is found in low numbers only in Arizona and Texas (and was once found in Arkansas and Louisiana as well), and is in the genus Leopardus, small spotted cats that inhabit the Americas; the Canada lynx (distributed in the Western United States, New England, Alaska, and Canada) and bobcat (ranging from southern Canada to central Mexico) are both in the genus Lynx, which inhabit Eurasia and North America.
The jaguarundi (Herpailurus yagouaroundi), found in Central and South America, also once occurred near the lower Rio Grande Valley in the southern tip of Texas, along with the margay (Leopardus wiedii); both are considered possibly extirpated from the United States.
Headquartered in Greenville, South Carolina, it was founded in 2007 by Danelle German, the organization's current president.
