2 minutes read Santiago, Apr 7 (efe-epa).- A group of South American paleontologists on Wednesday reported the discovery in Chile’s Patagonia region of fossil remains representing a new mammal species from the dinosaur era. The remains discovered in rocks in southernmost Chile’s Dorotea Formation, part of the Magallanes Region, consist of a partial mandible (lower jaw bone) containing five teeth in sequence and an isolated upper premolar. They date back to the Late Cretaceous (100.5 million to 66 million years ago), the final epoch of the Mesozoic Era, which lasted from about 252 million to 66 million years ago and is commonly referred to as the age of the dinosaurs.
