|Steppe bison were the ones painted at|
Altamira Cave in Spain (Wikipedia).
And they were a lot bigger in the good ol' days:
"The scientists compared the mitochondrial DNA from the fossil found at Ch’ijee’s Bluff [Yukon] to that taken from 45 other bison remains, including one of the oldest and most interesting specimens, the fossil of a giant, long-horned bison — belonging to the species Bison latifrons — found in Snowmass, Colorado.• All the kool kidz will be using these on their desert campouts soon. The Burners will have to have them.
“Bison latifrons is an interesting beast,” said Dr. Duane Froese, a geologist with the University of Alberta, in a separate statement.
“Its horns measured more than two meters across at the tips, and it was perhaps 25 percent larger than modern bison.”
