NEW YORK — Scientists have uncovered the mummified remains of cheetahs from caves in northern Saudi Arabia. The remains range from 130 years old to over 1,800 years old. Researchers excavated seven mummies along with the bones of 54 other cheetahs from a site near the city of Arar. Mummification  prevents decay by preserving dead bodies.  Egypt’s mummies  are the most well-known, but the process can also happen naturally in places like glacier ice, desert sands and bog sludge.
