The 11 scientists involved in the study told CNN it's too early to tell the impact of the new findings.

Experts agreed that the earliest records of human ancestors in North America is about 15,000 years old, but the discovery of the Cerutti site "shows that human ancestors were in the New World ten times that length of time," said paleontologist Lawrence Vescera.The discovery changes the understanding of when humans reached North America.The study, to be published this week in the science journal Nature, said the numerous limb bones fragments of a young male mastodon found at the site show spiral fractures, indicating they were broken while fresh.Evidence that they existed in the Southern Hemisphere has been mounting.Today's announcement of a well-preserved fossil represents the first definitive evidence that dromaeosaurs roamed South America as well._______________________________________________________________ Comment: 130,000 B. Therefore the theory of ancient Humans entering the Americas by crossing the Bering Straits, and then "By-passing" the FROZEN North American Continent, by Boat travel along the Coast, is totally out of the question.

The only other "Reasonable" possibility is an ATLANTIC crossing, similar to how ancient Africans reached Australia by "Island Hopping" more than 60,000 years ago.

Odds being against such striking parallel evolution, paleontologists speculate that dromaeosaurs more likely originated more than 180 million years ago, before Pangaea broke apart.

The newly discovered fossil also shows that the creatures developed slightly different characteristics after they split up.

The scientists say they found what appear to be hammerstones and stone anvils at the site, showing that ancient humans had the manual skill and knowledge to use stone tools to extract the animal's Bone Marrow and possibly to use its bones to make tools.

The site was named Cerutti Mastodon site, in honor of Richard Cerutti, who made the discovery and led the excavation.

The new find suggests such raptors go back much further in time than previously thought.
