Indigenous mammals include the leopard, hyena, fox, wolf, hare, oryx and ibex. There are 75 mammal species, among them marmots, Alpine ibex, and chamois. In Mongolia, they prey on argali and rarely Siberian ibex. Mammal species include the Nubian ibex and the rock hyrax. Competition with domestic and wild ungulates also contributed to the extinction of the Pyrenean ibex. The Pyrenean ibex was a subspecies of Spanish ibex that roamed on the Iberian peninsula. The hybrid ibex is a cross between a wild bezoar ibex and a domestic goat. The Alpine ibex is a mountain icon. The Pyrenean ibex was one of four subspecies of the Iberian ibex. The Axial Diverticulum is also decorated with cattle and horses accompanied by deer and ibex. It is sometimes considered a subspecies of the Alpine ibex. In January 2000, the Pyrenean ibex became extinct. The main range of this species in Iran closely overlaps with that of bezoar ibex. The Alpine ibex forms a group with the Spanish ibex. Proposed targets for cloning include the mammoth, the thylacine, and the Pyrenean ibex.
