Found one of this guys on a path to the summit of a mountain in the tundra(I don’t remember if it was on whitesky peak) while riding my argy. Was shocked by its level it was level 2 but it got 80000 health on it. Just flew away. Read its dossier beforehand and now I think because of that incident I have ptsd. Not all of my dinos can match up to that guy. Not even my Rex.
If one is encountered near water, you can simply lure it out to sea with a flyer and it will swiftly drown. Given the water is deep enough. If encountered inland not near water. Pray to the overseers you have something fast enough to out run it. Then promptly die because they're as fast as a mad Hispanic mother with a shoe. Not as deadly as one though.
