Pronghorns (Antilocapra americana) are cool!
One evening at the Dana Quarry dig, driving to the shower, we happened onto a herd of does and not-so-young fawns. They looked at us with interest, and when the car stopped they took off……
I have about a gazillion of these photos, but will spare you the rest.
I later saw an adult male with impressive horns, but we were driving by too fast to take a picture.

I have played with many of their skulls.
