Brontos are a bullet sponging machine if found with correct base health and melee you will make raiding easier can get 150 Brontos to around 70k health and swiping it's tail can destroy x seeds hella quick
This simply amazing creature in the ark world is the brontosaurus. This creature can mostly spawn anywhere and isn't extremely rare. To knock one out the best strategy I've found is to shoot it twice and get on a dino that is relatively quick and run away for a few seconds (very useful because it gives the narco time to take affect) next you get of the Dino again and shoot it two more times (or more depending on your distance from the brontosaurus). It does take quite a bit but afterward throw some carbonimius kibble or some mejoberries in it and wait for a bit. After you tame it the best thing it's for is the massive amount of berrys you can get by swinging your tail at a large group of bushes. It's also convenient because you can put a platform on its back to place strucures on. Finally it is very good at attacking thing because it knocks them back really far and does a lot of damage. That's pretty much all you need to know about taming and using the great brontosaurus!!!
The earlier you can tame one the better. We haven't even made a fabricator and we got one. We had so many narcotics taming became so much easier. Early game a low level is still good and is still hard to kill since it has knock back. Get one if you starting
If your in the center go to the northern tropic island, stand on one of the over passes the island has and shoot down at it, when it drops, walk to the end and jump in the water or use a pteradon to quickly go down and load up on your choice of food and narcs and keep watch, itll be yours in no time.
Don't be discouraged when it adds barely any taming. Because maybe they do take barely any taming points from a bite, but they bite constantly! So it is not as bad as meets the eye. Just have a steady stream of Narcotics and berries and you will be fine!
