width of the skulls where pieces of bone were missing. American scientists found this method inexact. American scientists thought the missing body to be Anastasia because none of the female skeletons showed the evidence of immaturity, such as an immature collarbone, undescended wisdom teeth, or immature vertebrae in the back, that they would have expected to find in a seventeen year old. In 1998, when the remains of the imperial family were finally interred, a body measuring approximately 5'7" was buried under the name of Anastasia. Photographs taken of her standing beside her three sisters up until six months before the murders demonstrate that Anastasia was several inches shorter than all of them. Her mother commented on sixteen-year-old Anastasia's short stature in a 15 December 1917 letter, written seven months before the murders. "Anastasia, to her despair, is now very fat, as Maria was, round and fat to the waist, with short legs. I do hope she will grow." Scientists considered it unlikely that the teenager could have grown so much in the last months of her life. Her actual height was approximately 5'2". The account of the "Yurovsky Note" indicated that two of the bodies were removed from the main grave and cremated at an undisclosed area in order to further disguise the burials of the Tsar and his retinue, if the remains were discovered by the Whites, since the body count would not be correct. Searches of the area in subsequent years failed to turn up a cremation site or the remains of the two missing Romanov children. However, on 23 August 2007, a Russian archaeologist announced the discovery of two burned, partial skeletons at a bonfire site near Yekaterinburg that appeared to match the site described in Yurovsky's memoirs. The archaeologists said the bones were from a boy who was roughly between the ages of twelve and fifteen years at the time of his death and of a young woman who was roughly between the ages of fifteen and nineteen years old. Anastasia was seventeen years and one month old at the time of the assassination, while her sister Maria was nineteen years, one month old and her brother Alexei was two weeks shy of his fourteenth birthday. Anastasia's elder sisters Olga and Tatiana were twenty-two and twenty-one years old respectively at the time of the assassination. Along with the remains of the two bodies, archaeologists found
