Meet the Saber-Toothed Squirrel

sciencehabit writes "Researchers have discovered the fossil remains of a 94-million-year-old squirrel-like critter with a long, narrow snout and a pair of curved saber-fangs that it would have likely used to pierce its insect prey. The creature, pieced together from skull fragments unearthed in Argentina and dubbed Cronopio dentiacutus, was not ancestral to us or any living mammal. Instead, it belonged to an extinct group called dryolestoids, a cadre of fuzzy mammals that scurried about in the shadow of long-necked dinosaurs."
