An obituary is made in an archaeological journal for the death of G. Codirolli which relayed the news of his passing to his friend and colleague, Professor Jones.[9]
↑Indiana Jones and the Unicorn's Legacy states Noah is fourteen months old in April 1928, therefore his birth is around February, 1927 and his conception in the year before. However, Indiana Jones and the Genesis Deluge is set in Spring 1927 where Noah is first predicted and the same event is where his parents first met. This would indicate Jack Shannon is not Noah's biological father despite the novel's intent that he is a product of their coupling.
