Players can either send along the coordinates one at a time or save them all up and do it in one sweep. Once a dinosaur bone is found, players can head to the nearest post office and choose the “send mail” option. At the end of the conversation, players will be directed to find the 30 dinosaur bones and mail the coordinates to Mss MacGuiness. Approach Miss MacGuiness and speak with her about what she’s doing. This hill is in New Hanover, below the “H” in The Heartlands. To start the A Test of Faith mission, players will need to find Miss Deborah MacGuiness, a palaeontologist who is located on a hill northeast of Flatneck Station. Locating all 30 dinosaur bones is no easy feat, as they can be quite difficult to spot, but the reward is worth the time spent wandering around. Buried around Red Dead Redemption 2 are 30 dinosaur bones and fossils for players to find and collect as part of the Stranger mission, A Test of Faith.
