Researchers discover T. Rex dinosaur’s predecessor

A group of paleontologists has discovered a new dinosaur species, dubbed Eodromaeus, at the foothills of America's Andes.

The long-necked Eodromaeus was a fast-running carnivore. It was around 5 feet in length, and had a very long tail and was 15 to 17 pounds in weight.

Eodromaeus is the most primal dinosaur found so far among the theropods. It roamed South America around 230 million years ago, only a few million years after dinosaurs first evolved.

Paleontologist Paul Sereno, of University of Chicago, said that the discovery of Eodromaeus would provide more information about early dinosaur life.

Commenting on the topic, Sereno said, "We're looking at a snapshot of early dinosaur life. Their storied evolutionary careers are just unfolding, but at this point they're actually quite similar."

Researchers also said that dinosaurs were more common and diverse in the Ischigualasto zone in the Triassic geological period than had been formerly believed.

Eodromaeus is thought to be a predecessor to later meat-eating theropods.
