I was playing on a nice multiplayer survee with nice people, I got a bronto, mutated blue wolf, eerie tapejara, and an argie. I join a tribe with someone and we go to his base (on the back of fars peak and right across from carnivore island) and one day I spawn in, and see one of my arges died, I'm like oh. It must have starved. That's sad. Then I look at the logs and see "your dodo has been killed by a giganotosaurus!" I instantly start panicking and I type in the chat about it. Everyone is curious. Low and behold I see a giant giga tail right next to my flimsy base with spike walls. It agros on me, and I start RUNNING. My bronto attacks it and the behemoths fight. My bronto's death was not in vein though. I had enough time to save 5 out of 17 dinos. I'd say that's pretty good compared to nothing. I still have their graves to this day.
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.
I spent an hour taming a Max lvl anky on a ledge. After about 20 minutes I looked down and 2 gigas were below looking right at me their heads almost reaching the top of the ledge. They stayed there the entire time
