In earlier times several skulls dug up in North America were touted as resembling European Neanderthals. There are a couple from the Great Plains area, some the Midwest and then again a couple in New Jersey. Brian Switek (Laelaps) has a blog posted about the New Jersey skulls and here is the link to it:
And the skulls are most peculiar in being very broad and low: they do seem to have a general Neanderthal sort of appearance when viewed from the face-forward. There are stray skulls of this type reported periodically from as far away as Southern Brazil and Argentina.
