Thanks to an abundance of fossils in Bat Cave, Missouri, paleontologists have been able to interpret seasonal social habits in the extinct flat-headed peccary, which lived tens of thousands of years ago during the Late Pleistocene Epoch.

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.

The Gray Fossil Site in East Tennessee preserves the remains of a diverse ecosystem dating to a time called the Late Hemphillian Stage and home to tapirs, alligators, mastodons, red pandas, and more. Now, a study published in the Bulletin of the Florida Museum of Natural History unveils the latest new species from the site, a rhinoceros named Teleoceras aepysoma. At an estimated 4.5-4.9 million years old, these were among the very last rhinos in North America.
