This season introduced the ability to getting better weapons by upgrading your existing weapons.

This quest is to craft primal weapons by using animal bones and a makeshift weapon.

Makeshift weapons will be easy to come by. If you are upgrading solely for this quest I would recommend a common makeshift weapon so they require less animal bones to craft into a primal weapon.

Animal bones can be found by killing animals or by destroying bones across the map. If you are in a primal area of the map, for example Boney Burbs you will find animal skulls on sticks. Hit them with you pickaxe and they will drop an animal bone.

When you have a makeshift weapon and enough animal bones you will need tp open up the crafting menu, choose the weapon you want to craft and hit craft.
