Pope Francis appoints auxiliary bishops for Archdiocese of Baltimore

Ancient crocodile

Crocodiles may have a nasty, nightmarish reputation among most people, but the leathery, toothy, snappish critters have been around so long that they probably gave most dinosaurs a fright, too. University of Chicago paleontologist Paul Sereno and his colleague at McGill University in Montreal, Hans Larsson, on Thursday unveiled fossils of five ancient crocodile species that lived with and, in some cases, even hunted down and ate up dinosaurs that once roamed what is now Africa's the Sahara Desert region of Africa. This CuckCroc was discovered in Niger.
