There’s a bit of a difference between skeletons being in such poor condition that archeologists cannot tell the sex, and the fact that when skeletons are in good condition sex is easily observable. I fucking despair that you’re about to graduate and you cannot tell the difference between the two circumstances

Why yes, I can tell the difference. We were talking, afterall, about a hypothetical future in which taphonomic processes and just general decay of the living matter in the bone tissue is going to take place! Did you even think before sending in this ask? You're almost as dumb as the person who said coffins exist now implying they didn't in the past.
