I agree with Berlin Freeper than there's a strong likelihood that this individual was different and, therefore, he was buried differently.
However, he may have been buried this was in shame because he committed suicide, which wasn't 'manly.'
Or he was a potter.
Or he showed cowardice in battle.
Or he was a shaman or priest.
Or he was the cultural story-teller.
We must speculate at the reason that his burial was different. We can't simply say "yep, he was transexual or gay. That's the answer."
Remember how many things we were taught about dinosaurs based upon the discovery of bone fragments? And all the arguments of the last twenty years that also seem to be speculation that go against those first 'facts' we were taught?
In the next article on this caveman, we're going to hear that they found a round-ish talisman with a hole in it in the grave. Signifying that he wore it around his neck on a strand of leather, making it his prize possession. And there appears to be a line on the talisman that makes it look like a pumpkin - am American vegetable - WHICH IS POSITIVE PROOF THAT THERE WAS A TRADE ROUTE FROM THE AMERICAS TO CZECHOSLOVAKIA IN 2,500 BC!
Maybe the person who buried him had only buried a woman before by whatever cultural norm existed before culture.
Or maybe the people who buried him buried men and women the same way and any different burials found had nothing to do with sex.
