Extremely high aggro rage, so using a tanky flyer like a quetzal is recommended. If you are using a trap, build it out of metal as, although they can damage it, takes a lot of tome for them to do. It takes about 20- 35 tranq darts to knock it out, and once it is, its torpor decreases extremely fast. Anything but exceptional/giga kibble is extremely useless, and even with it, needs about 500-1500 narcs to tame it.
Extremely hard to tame. Only gets knocked out if you use rocket launcher. Takes about 1500 shots to the head for knockout. Only eats fertilized giga eggs during taming. Only eats raw prime meat after taming. Can one shot titanosaurus. My base got pillaged by one of these guys. I lost my dinos and entire base and all of my stuff. They can aggro on you as soon as it is rendered in.
