Whenever I come across a game with collectibles, I make sure to mark where I find each one, so that I have a map of what I'm finding that will allow me to later look for the ones I have left to get 100%. Seeing that there was no guide to the game other than videos, I decided to make these maps that I have a little more "formal" and upload them here, in case it helps more players.

This is the first guide I've made, and my English is a bit mediocre, so I'm sorry for any mistakes! Any friendly comments are greatly appreciated. Enjoy the game and be happy!

There is a "hidden" collectible in the form of 3 dinosaur figures, each spread across the jungle, swamp and dune maps. These figures are found in high, unreachable areas of the map, and you have to take photos of them to count them and thus unlock the hidden entrance, necessary for the "That's gotta be an easter egg" achievement.
It is important to keep this achievement in mind if you want to complete 100% of the game, because once you finish an area you cannot return to it, making achievements related to collectibles potentially lost. For this reason, I will mark the area where each figure is located on the maps, and I will leave some hidden photos to help locate them better (since they are more hidden than the rest of the collectibles).
