Okay, so Zahi thinks the mummy in the coffin belonging to the nurse is the real queen. Did they do a blood test or DNA test on the organ in the canopic jar, then?
Also, I noted they said the mummy was on the 3rd floor of the museum. I only remember two floors open to the public when I was there, with the royal mummies in a room at one corner of the second floor, so that sounds like some kind of attic.
Finally, it doesn't surprise me if Hatshepsut didn't have as much gold and jewelry to show off as Tutankhamun did. Nubia had just been conquered, and Syria wasn't part of the "empire" yet, so Egypt wasn't as rich as it would be in a century or two.
Also, her tomb was plundered in antiquity.
