Best way to combat these guys is if you have a bola and torch. Bola stops them from moving a torch burns them. If you don’t have a bola a torch can still do some good by itself until you get a bow and arrow or a tame that can fight them easy aka a triceratops or carb or another raptor if you manage to tame one. Remember raptors are pack creatures so….. if you see one there are always more in the area
