Fossils of the oldest ancestor of the fearsome Tyrannosaurus rex were found by palaeontologists from Argentina and the United States in the Valle de la Luna, San Juan. The results were published yesterday in the journal Science.
The species, named Eodromaeus ("dawn runner" in Latin) lived 230 million years ago (Late Triassic) and is the most primitive dinosaur known to date between the theropods and the lineage of bipedal carnivores that gave rise to birds. Eodromaeus
lived in the period that scientists called the "dawn" of the dinosaurs. "He measured about 1.60 meters long, had the tail and neck very long, and weighed no more than 7 or 8 pounds, very light, the size of a turkey more or less," said Ricardo Martinez, a paleontologist Universidad Nacional de San Juan.
