One of the artifacts found in of the treasury of Tutankhamun’s tomb was an unassuming looking wooden chest. Inside were two small gold coffins that, upon being opened, were each found to hold a carefully preserved fetus. Both were less than 40 cm long, and both were believed to have been born prematurely.
The smaller of the two was found to have been about 4 months premature, and still had part of the umbilical cord preserved on it. The second and larger one was determined to be either close to term or a month premature, and had either died at or shortly after birth. This second child also showed evidence of deformities, as well as Spina Bifida and Scoliosis.
Recent DNA tests have confirmed that these two tiny girls are indeed the children of Tutankhamun. It is generally assumed that their mother, therefore, is Ankhesenamun, as he is not known to have had any other wives during his short reign.
