Alene, they don't have too much of a use. As a pack, they will heal up annoying amounts of health. Keep them in pairs for base defense along with triplets of microraptors and small packs of raptors for a visciously effective and tanky crew that don't look too dangerous from afar. Add pegomastaxes to the mix to steal loot from your unfortunate attackers.
So super easy way to tame these guys, Hit them once with any kind of fast moving of flying dino and let them use their healing. After the healing aura goes away Ko them. Instatamed since their food meter is fully empty 😁
