How do I find all dinosaur bones for the "A Test of Faith" achievement?

To unlock the ''A Test of Faith'' achievement in Red Dead Redemption 2, you must find and collect all 30 dinosaur bones scattered across the game world. This task is part of the Stranger mission ''A Test of Faith,'' which becomes available in Chapter 2. The mission is given by Deborah MacGuiness, a paleontologist located in the town of Valentine. She will ask you to locate dinosaur bones, and you can track your progress in the ''Progress'' section of the game menu.\n\nDinosaur bones are small, white, glowing objects found in specific locations across the map. They are often hidden in hard-to-reach or obscure areas, so exploration is key. To make the search easier, you can use the in-game map and the ''Dinosaur Bone Map'' item, which Deborah provides after you find your first bone. This map gives vague hints about the locations, but it’s not detailed enough to pinpoint exact spots, so you’ll need to rely on your exploration skills.\n\nSome bones are located in remote or dangerous areas, such as near predator-infested regions or high cliffs. For example, one bone is found in the Grizzlies East region, near the edge of a cliff overlooking the Dakota River. Another is located in the heart of the Bayou Nwa, where alligators are a constant threat. Always be prepared with weapons, health tonics, and a good horse to navigate these areas safely.\n\nTo find all 30 bones, you’ll need to explore every corner of the map, including New Hanover, West Elizabeth, Ambarino, and Lemoyne. Some bones are hidden in caves, while others are buried in the desert or tucked away in dense forests. For instance, one bone is located inside a cave near Window Rock, while another is found in the desert near Armadillo. Use your binoculars or Eagle Eye ability to spot the glowing bones from a distance.\n\nA common challenge players face is locating bones in areas with limited visibility, such as dense forests or foggy mountains. In these cases, use your Eagle Eye ability to highlight the bones’ glow, even through foliage or weather conditions. Additionally, some bones require climbing or careful navigation, such as the one near the top of Mount Shann. Be patient and use your horse to reach higher ground when necessary.\n\nOnce you’ve collected all 30 bones, return to Deborah MacGuiness to complete the mission and unlock the ''A Test of Faith'' achievement. Keep in mind that this task is time-consuming and requires thorough exploration, so take your time and enjoy the journey. If you’re struggling to find a specific bone, consider using online guides or maps for precise locations.\n\nPractical tips for this achievement include marking potential bone locations on your map as you explore, using the Legend of the East Satchel to carry more items, and saving your game frequently in case of accidents or attacks. Additionally, completing this achievement early in the game can provide a sense of accomplishment and help you familiarize yourself with the vast world of Red Dead Redemption 2.
