| Cheetah provides clue to pronghorn speed | |
| 1995 Rocky Mountain News | |
Paleontologists found fossil animals from a cave floor. This natural trap has preserved direct evidence that cheetahs lived in North America as recently as 18'000 years ago. This also explains why pronghorn in America evolved a high speed ability which was not explainable before finding the fossil predator. |
