Dinosaur Bones | Red Dead Redemption 2 Wiki

Dinosaur Bones are special Collectibles in Red Dead Redemption 2 (RDR2). Players must collect all 30 of these items to complete 100% of Trophies / Achievements.

All Dinosaur Bones of RDR2

You record the finding of your first bone once you obtain the Stranger Mission: "A Test of Faith" from Deborah MacGuiness after Chapter 2, and will continue to gather them throughout the game. It is best to hunt for them after completing all Story Missions, as bounty hunters will no longer be available.

How to collect bones

The dinosaur bones are obvious and large as you explore the regions, and will complete one skeleton. You can inspect areas by highlighting aspects (press both thumbsticks). Once you have found them all return to Deborah to complete the quest.
