One of the most interesting things that I have seen pictures of and read about is what is commonly called "Coneheads", which were people who lived about 2,000-3,000 years ago, and who all had very large and elongated heads. These skulls have been found on virtually every continent in the world, and the greatest amount seems to have been found around Peru. While some of the skulls that have been found do seem to have been artificially shaped that way by some form of binding on the skull, many of them appear to have been this way naturally. Most of the skulls that have been found were people who were considered the royalty of that civilization, so archeologists think that some of the ones that were bound to make them appear longer were people who were trying to make their children appear like they were from the long-skulled royalty background. One area where the skulls have been found in Peru is near where the famous Nazca Lines are at, and since these lines were made before the Nazca people moved into the area, it is a distinct possibility that they were also made by the Conehead people. Since these people were living here as recently as 2,000 years ago, it is not like they were some sub-human species, or a form of gorilla (which also have longer skulls). Whether they were a defferent form of human that died out, or if they were some kind of an alien-human hybrid species , is one of the questions that we have no answer for, at least at this time.
