But it wasn't until now that scientists were able to accurately date the findings, and possibly rewrite the history of the New World as we know it.
Toward the end of the Jurassic period, it split in two.Since dromaeosaurs had only been found in places that used to be part of Laurasia, scientists figured that the beasts evolved into being after Pangea split.But the Buitreraptor fossil in South America, which dates back 90 million years and closely resembles fossils from the North, means one of two things: Either dromaeosaurs existed when Pangea was intact; or the newfound Buitreraptor and its northern look-alikes evolved separately yet with remarkably similar results.It has a long head and long tail and wing-like forelimbs.Its serrated teeth, like steak knives, suggest it was a carnivore.
