Scientists find remains of 15-pound dinosaur

A team of paleontologists and geologists from Argentina and the United States of America on January 13 announced the discovery of a lanky dinosaur that roamed South America, approximately 230 million years ago.
Sporting a long neck and tail and weighing only 10 to 15 pounds, the new dinosaur has been named Eodromaeus, the “dawn runner”, and it is believed to be the biggest of them all.“It really is the earliest look we have at the long line of meat eaters that would ultimately culminate in Tyrannosaurus rex near the end of the dinosaur era,” said Paul Sereno, University of Chicago paleontologist and National Geographic Explorer-in-Residence. “Who could foretell what evolution had in store for the descendants of this pint-sized, fleet-footed predator?”

Mr Sereno and his colleagues describe a near-complete dinosaur skeleton of the new species, based on the rare discovery of two individuals found side-by-side, in the January 14, 2011 issue of the journal Science. The paper presents a new snapshot of the dawn of the dinosaur era—a key period that has garnered less attention than the dinosaurs  demise. “It’s more complex than some had supposed,” Sereno said.

Set in picturesque foothills of the Andes, the site of discovery is known as the “Valley of the Moon,” said lead authors of the report, Ricardo Martinez of Argentina s National University of San Juan. For dinosaur paleontologists, it is like no other.
