dinosaur from South America New York, Dec 13 (THAINDIAN NEWS) New fossils have been found that point to the fact that dinosaurs originated from the region of South America. There has been a new and exciting discovery of a primitive precursor to Tyrannosaurus Rex, which points the origins of the dinosaurs to South America. Paleontologists reported this on Thursday.

The Science journal, reported about Tawa hallae, which was discovered by a team led by Sterling Nesbitt of the American Museum of Natural History in New York. This ‘revolutionary’ fossil was found in a fossil bone bed near New Mexico’s Ghost Ranch. Nesbitt’s team named this primitive fossil creature, after a Pueblo sun god and the fossil collector Ruth Hall. It is a 6.5-foot-long meat-eating precursor to T. Rex.

This dinosaur is said to be 6-to-12 foot-long, and is a meat-eating creature. The first dinosaurs developed about 230 million years ago, and T. hallae skeletons date from about 213 million years ago, according to researchers led by Sterling J. Nesbitt of the University of Texas at Austin.

This dinosaur contains characteristics of various lineages, which will eventually help in understanding evolution of the various forms of dinosaurs, the scientists said.

“Tawa helps us reconstruct the origins of all the most primitive dinosaurs, suggesting they were likely located in South America,” Nesbitt says. The dinosaur, “probably ate anything he got his hands on,” he adds.
