Players can find 30 dinosaur bones in the vast world of Red Dead Redemption 2. They serve as collectibles that are hidden throughout the map. From the outskirts of Tumbleweed to the edges of Annesburg, these bones are everywhere. To start collecting, you will need to speak to Deborah MacGuiness, a paleontologist who needs help finding the dinosaur bones.
It’s possible to find dinosaur bones before meeting the paleontologist. However, players will only be rewarded after they’ve been in contact with MacGuiness. Players will get one reward after they send their first location. After that, every 15 dinosaur bones will be exchanged for a reward, so you’ll receive three rewards in total.

Meeting the Paleontologist
South of the H in Heartlands and the badger drawing, there should be a stranger marker. When you first see Deborah, she will be busy unearthing a bone next to an empty wagon. After agreeing to help her, Arthur will be obligated to send Deborah scribbled coordinates to the bones. Sending off their locations can be done after finding all 30 or mid-way, but sending their locations is how Arthur will receive rewards for his findings. Once Deborah obtains the details from Arthur, she’ll be on her way to unearth the bones.
