Re: Dr. Holtz' secret: Buitreraptor gonzalezorum

A curious note from Msnbc: "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."

Not that I'm the biggest fan of secondary flightless dromeaosaurs, but doesn't this discussion leave out the possibility that Buitreraptor's ancestors flew to the southern hemisphere in the Early Cretaceous?
