There are a total of thirty dinosaur bones in Red Dead Redemption 2, such as Dream Catchers, all of which are required to validate 100% progress and are included in the collectibles category. Bones are on the ground and are easily confused with common animal carcasses, which can make them difficult to find unless you look for them specifically and know where to look. You can start tracking them and recording their coordinates (in play) as early as Chapter 2, preferably after you have accepted Deborah MacGuiness's quest, just north of Flatneck Station. You don't need to pick up the bones, just send him a letter by post with the information and this good lady will take care of the rest.
You can spot them more easily with the Lynx Eye, which will make them shine yellow.
Unfortunately, it is impossible to complete this quest until you have completed the main story, as some of the bones are in Austin, an area you cannot enter because of the mercenaries who instantly kill you on sight.
Once the thirty dinosaur bones have been found, send their contact details to Deborah via post and wait 24 hours for her answer. She will send you an invitation that you will receive at the counter. You can then go to her home to admire the reconstructed skeleton and to receive a bone knife.
Here is a general map with red dots to indicate the bones. As they are small and easy to miss, the dots are also small in size for greater accuracy. Click on the map to zoom in.
Be aware that there are some intermediate rewards to encourage you before you have found the thirty locations. Having a good horse and unlocking the fast journey through camp improvements can help speed things up.
