the one in discovery said that it was really her..
first it was speculated that the mummy was a man, but then the size [i guess] of the pelvis, and the absence of a penis, gave way to proving that it was indeed a lady. It was estimated that the age of the lady was between 18-25, but Nefertiti died in her thirties, and also by observing the mummy pelvis, it could be said that it never gave birth, totally impossible if it was really Nefertiti [because the Queen gave birth to many daughters]. The mouth of the mummy was deformed so it can't speak its name to the Gods in the judgment.
Hawass has banned Joanne Fletcher from Egypt.

I guess because he thought it an insult that one of the greatest queens of Egypt was nly buried in a corner [well, i guess u know what i mean]
