Scientists in Buenos Aires have announced the discovery of a new dinosaur species deep in Argentina's southern Patagonia region. The fossil remains were found in the province of Santa Cruz just a few miles outside of the tourist town of Calafate, and belonged to a six or seven meter long carnivore. Like many of the new dinosaur species being documented by scientists, the fossil dates back to the Cretaceous period some 70 million years ago. (Reuters)
