For decades, paleontologists have held up uintatheres as a prime illustration of sexual dimorphism, or the tendency for males and females of a species to be physically different. Notable for their large size, prominent horns and canine teeth, uintatheres emerged about 58 million years ago, fewer than 10 million years after a space rock killed the dinosaurs, and show up in the fossil record for the next 20 million years or so.
