Take away the heights, and all we have left to do is determine where in the developmental process does each skeleton fall? The following is based upon our own conclusions we made on the two questionable sets of remains.
~Lishka~

The sacrum of No. 5 wasn't fully developed at the time of her death, making her the youngest of the found Grand Duchesses. Right away it's either Maria or Anastasia, but we are inclined to believe the latter. Sacrums mature at the age of 18, and Maria being 19 at the time of the murders indicates that her sacrum and pelvic rim would have been mature. No. 5's wisdom teeth were coming in when her development was rudely halted, the tips of her roots had only just begun to grow. Her limb bones told Dr. Maples that her growth had only just recently ended, fitting the description of Anastasia Nicolaievna.

Dr. Maples also said that her back showed evidence of immaturity, but thought that it was the back of an 18 year old. Now Anastasia was a hyper child who lived off of spontaneity. Generally, cartilage in your major joints (such as the knees and wrists - those parts that are very active all throughout life and go through a lot of "wear and tear") harden when one is around 16 years of age. Climbing trees especially puts strain on the back, and was a favourite activity of the youngest Grand Duchess. It was not widely known that she also had a bad back and was given massage therapy twice a week for it. This naturally produces more strain on her back. Did any of the scientists consider that?

 The condition of No. 5's remains came as a shock. The scientists did not have a complete skeleton to work off of, she had been too badly abused by her murderers. In Anastasia Dead or Alive, Dr. Maples showed us the skull that belonged to No. 5.. or what little was left of it. His book Dead Men Do Tell Tales shows a front view of the few remaining pieces: the eye orbits, and the beginning of the bridge of the nose. Half of the middle face was missing, a pattern of damage that was seen in Olga's remains as well. The sorry condition of this skull reminded us of one point in Yurovsky's note: when one of the Grand Duchesses was being laid on a sheet she supposedly sat up and cried out. The whole band of soldiers was said to turn on her with their bayonets. The damage patterns fit this description, and it is possible that Shvibz could have survived the round of bullets, but sadly it seems that the youngest of the four girls was struck down that night.
