Collect crafting materials whenever you find them and craft basic tools with stones as soon as you are able to so you can use them to help build your shelter. To build a decent sized shelter you will need plenty of supplies like logs, bamboo, and stones and when you build it the walls need to be firm so that they cannot be easily breached by dinosaurs that roam into your shelters vincinity.
You first need to lay a floor for your shelter using bamboo, then place the walls and a door section. When placing workbenches and other crafting stations they need to make sure they are placed on a floor tile and not the bare ground. Then to help keep dinosaurs away from the shelter create traps around the perimeter by using logs that have been sharpened into spikes.
