This guide is not going to point out the location of everything as the game does it for you. There are 2 skills related to these collectables which will help.
One, that is unlocked at Tier 2 of your skills, allows you to press L1 to detect collectables close to you. Once they are detected they will appear in your map.
The other skill is unlocked at Tier 3 and will show you the location of every treasure map and tomb entrance. This one will allow you to find the maps in game that will show all the collectables on your map.
