Fair question....? Didn't they have a way to deliberately elongate the heads in past times? I know things like the neck is elongated in some African tribes by adding a ring at frequent intervals, essentially for years or life. Each ring, adding just a hair more length as growth compensates. Is that possible with the skull? (I seem to recall hearing it was...but not sure?)
Even if those are humans after contemporary modification like that, it's a great find! How fascinating. Something also tells me that one of these
days they are going to find skeletons far enough outside expected norms to really blaze headlines with. Just a hunch... S/F!
