I am not a medical expert but I concur that having molten metal poured over your head and having signs of healing would have very little correlation
Thanks for the link, it also answered my question about the shape of the skull.
Yes, this is a real human skull that is thousands of years old. Elongation was achieved through head binding beginning at a very young age. It was typically practiced to convey social status by various cultures.
