A few nice extinct animal images I found:
Bighorn Sheep (Ovis canadensis) DDZ_0025

On 8 June 2008, three groups of adult Bighorn rams totaling 18-20 animals were observed grazing along Interstate 84 in the Columbia River Gorge near the John Day dam. This large ram appeared to be keeping watch from a perch atop a large boulder.
Two hundred years ago, Bighorn Sheep were widespread throughout the western United States, Canada, and Northern Mexico. Some estimates placed their population at higher than 2 million. However, by around 1900, hunting, competition from domesticated sheep, and diseases had decreased the population to only several thousand. A program of reintroductions, natural parks, and reduced hunting, together with a decrease in domesticated sheep near the end of World War II, allowed the Bighorn Sheep to make a comeback, though not before Ovis canadensis auduboni, a sub-species that lived on the Black Hills, went extinct.
