I was looking up stuff on Megaraptor when I happened upon a website saying that Megaraptor may not be related to Velociraptor or Utahraptor because U.Raptor an V.Raptor where found on laurasie and M.Raptor was found on Gondwanaland.This site actually had a quote from you on it,Dr.Holtz.Here is the web address http://pages.prodigy.net/fenrisulf/geology/geo1.htm. And what i would really like to know is if they are related or not.

TOM: We are not yet certain exactly where Megaraptor fits on the family tree, because so little of it is known (just a few bones). Hopefully someone will find more bones so we can figure out where it belongs. It turns out, however, that there might have been more similarity between the dinosaurs of Gondwanan and Laurasia than once thought.
