  • Because many dinosaur bones are in the regions which cannot be accessed by Arthur Morgan unless using glitches, players not using glitches have to complete this Stranger mission as John Marston.
  • If a player collects all the Bones with Arthur using glitches to enter New Austin there is an alternative version of the final cutscene with Arthur reacting to the creature. This might be a sign that it was originally possible for Arthur to enter New Austin on game legal ways.
  • 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.
