Trivia

Because many dinosaur bones are in the regions which cannot be accessed by Arthur Morgan, John must complete the bones
Arthur can collect bones in New Austin through a glitch or exploit, upon returning to Deborah there is dialogue which proves that this was meant to be completed as Arthur Morgan. In fact, the only additional dialogue would be from Arthur as Deborah would say the exact same thing if the player met her and completed the mission as John.
Although Deborah asks for dinosaur bones, several bones that the protagonist finds do not belong to dinosaurs.
This mission parodies early depictions of dinosaurs such as Richard Owen's Megalosaurus or Gideon Mantell's Iguanodon.
