  News from the Gray Fossil Site & Museum


Over the last 20 years, dozens of extinct animal species have been identified from the five-million-year-old ecosystem of the Gray Fossil Site in Gray, TN, including famous large mammals like tapirs, rhinos, and mastodons. But in recent years, researchers have been uncovering more information about the small mammals of the site.

In a deep pit inside an underwater cave in the Yucatán Peninsula of Mexico, paleontologists have discovered the fossils of two unexpected carnivorans, a bear and a wolf-like predator which were once thought to have lived only in South America. Fossils from Middle America are rare, and these ancient predators help shed light on the history of animal evolution and migration through the region.
