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.
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.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.Buitreraptor is related to Velociraptor, the presumed cunning killer made famous by Hollywood.Both belong to a class of birdlike dinosaurs that ran swiftly on two legs and are called dromaeosaurs.It has a long head and long tail and wing-like forelimbs.
