Hey guys, Tara here for Dnews - and if you like dinosaurs, then you're gonna love this story. A new fossil uncovered in Patagonia has provided the first evidence that certain dinosaurs survived the great extinction, and existed millions of years after they were thought to have died off. The diplodocid sauropod is a family of long-necked, whip-tailed dinosaurs - made famous by this scene from the second Jurassic Park movie. They are some of the longest creatures to ever roam the earth, and they were assumed to have gone extinct at the end of the Jurassic era - around 150 million years ago. Thanks to this new finding, however, researchers in Argentina now have the earliest record of them in existence, dating back to the early Cretaceous period - around 130 million years ago. Even more interesting, it was found in a place they never expected: South America. Eight vertebrae were discovered in the rocky outcrops of the "Bajada Colorada," a Cretaceous-era formation in western Argentina. This is the first time this family of dinosaurs has been found in any southern land mass, aside from Africa - which, according to researchers, means they must have evolved from other dinosaurs before Africa and South America split apart. Until now, the species was thought to be an exclusively North American dinosaur. So this new evidence, researchers say, may help shed light on how different dinosaurs migrated around the globe in response to climate change. It's kind of amazing how much we continue to discover about the world around us. And I dunno about you guys, but dinosaurs are one of the most fascinating things in the world to me. Hopefully you agree. And if you have any thoughts about this finding, feel free to leave them in the comments below - otherwise, thanks for watching!
