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
Bronto's are a beast! Make a platform saddle, have mortar and pestles on it, carry spoiled meat and you will make thousands of narcotics in no time! Also a great thatch gatherer, would definitely recommend taming the Bronto.
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!!!
Build a platform with furnaces and storage on it's back, take it out to a metal filled area, gather metal all whilst dumping it into it's inventory. When your done put all the metal into the massive amount of furnaces you have on it and smelt it up, then store it!
