Find a high level Male & Female Raptor, preferably over level 100 (this is only recommended for higher levels) then once you have tamed them (try and tame them as perfect as possible) start breeding them as much as you possibly can, even if that means getting another high level female, then make sure your base is enclosed with walls etc then let them roam free around the base, if you have loads of raptors they will defend your base really well because of how fast they are and how strong making them a reliable defence Dino.
