As with all types of dinosaurs, paleontologists are unearthing new raptors all the time. One of the latest to join the flock is Austroraptor, which was "diagnosed" in 2008 based on a skeleton dug up in Argentina (hence the "austro," meaning "south," in its name). To date, Austroraptor is the largest raptor yet discovered in South America, measuring a full 16 feet from head to tail and probably weighing in the neighborhood of 500 pounds--proportions that would have given its North American cousin, Deinonychus, a run for its money, but would have made it no match for the nearly one-ton Utahraptor that lived tens of millions of years earlier.
