Tutankhamun's mummy
On January 15, 2005, under the direction of Dr. Madeeha Khattab, the Dean of the School of Medicine at Cairo University, Tutankhamun was removed from the tomb and a CT scan (computerized tomography) was performed on the mummy. The scan allowed for accurate forensic reconstruction of his body and face, as well as further evidence of his cause of death. Testing showed there was no traumatic injury to the head, he had a small cleft palate that went probably unnoticed, and the elongated shape of his skull was within the normal range and appeared to be a family trait after some studies were done on mummies that were believed to have been related to Tutankhamun. Based on bone maturity and his wisdom teeth, Tutankhamun was confirmed to be 19 years old at the time of his death. The CT scan proved Tutankhamun was in good health and did not show any signs of disease that would have affected his build. Study concluded he was not murdered from traumatic head injury, but a non-violent murder could still not be ruled out. There appeared to be no indication of any long-term disease.
Akhenaten
Similarly, although it is accepted that Akhenaten himself died in Year 17 of his reign, the question of whether Smenkhkare became co-regent perhaps two or three years earlier or enjoyed a brief independent reign is unclear. If Smenkhkare outlived Akhenaten, and became sole pharaoh, he likely ruled Egypt for less than a year. The next successor was Neferneferuaten, a female pharaoh who reigned in Egypt for two years and one month. She was, in turn, probably succeeded by Tutankhaten (later, Tutankhamun), with the country being administered by the chief vizier, and future pharaoh, Ay. Tutankhamun was believed to be a younger brother of Smenkhkare and a son of Akhenaten, and possibly Kiya although one scholar has suggested that Tutankhamun may have been a son of Smenkhkare instead. DNA tests in 2010 indicated Tutankhamun was indeed the son of Akhenaten. It has been suggested that after the death of Akhenaten, Nefertiti reigned with the name of Neferneferuaten but other scholars believe this female ruler was rather Meritaten. The so-called Coregency Stela, found in a tomb in Amarna possibly shows his queen Nefertiti as his coregent, ruling alongside him, but this is not certain as the names have been removed and recarved to show Ankhesenpaaten and Neferneferuaten.
