By Gisela Crespo, CNN, April 26, 2017 The remains of a mastodon discovered during a routine excavation in California shows possible human activity in North America 130,000 years ago -- or about 115,000 years earlier than previously thought.
Paleontologists with the San Diego Natural History Museum discovered the remains of the elephant-like animal more than 20 years ago.
Legend: Mesoamerica = Mexico and Central America Pre-Columbian = Before Christopher Columbus Amerindian = Indigenous Indians of North and South America Paleoindian/Paleoamerican = The original Black settlers of the Americas The discovery of a bird-like dinosaur in South America has paleontologists rethinking when, where and how one group of raptors evolved.
The rooster-sized dinosaur is called Buitreraptor (bwee-tree-rap-tor) gonzalezorum.
There is already abundant evidence that by 11,000 B.
What we call Laurasia eventually became North America, Asia and Europe.
The other chunk Gondwana, developed into the continents of the Southern Hemisphere and India.
_______________________________________________________________ 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.
