The Mexican grizzly bear (''Ursus arctos'') is an extinct population of the Brown bear. All grizzly bears are brown bears. Only the notable distinctions of this population from other populations are discussed here. The holotype was shot by H. A. Cluff at Colonia Garcia, Chihuahua in 1899.〔Clinton Hart Merriam: ''Descriptions of New Bears of North America'' In: Proceedings of the Biological Society of Washington (1914), p.190-191.〕 The extinct California grizzly extended slightly south into Baja California Norte. The bears in Durango, Chihuahua, and Sonora and central Mexico were likely more related to the bears of Arizona, New Mexico, and Texas than to those of California. ==Description== Known in the Opatas language as the pissini, the Mexican grizzly bear was one of the heaviest and largest mammals in Mexico. It reached a length up to and an average weight of . Due to its silver fur it was often named "el oso plateado" (the silver bear).〔David Day: The Doomsday Book of Animals. Ebury Press, London〕 The Mexican grizzly bear was smaller than the grizzly bears in the United States and Canada. The general color was pale buffy yellowish varying to grayish-white, grizzled from the darker color of the underfur. Specimens in worn pelage varied to yellowish-brown and reddish. The longest fur hairs were on the throat and the flanks. The belly was sparsely haired lacking the thick underfur of the back and the flanks.〔
