How did a 3-foot-long, furry, plant-loving beaver-like animal with buckteeth outlive the dinosaurs? New fossil remains found in New Mexico provide scientists with some important clues.
"It's interesting that this odd, now extinct group, was among the few to survive the mass extinction and thrive in the aftermath," said Thomas Williamson of the New Mexico Museum of Natural History and Science, who led research that appeared Monday in the Zoological Journal of the Linnean Society. "It may be because they were among the few mammals that were already well-suited to eating plants when the extinction came."
