ARK: Survival Evolved & Ascended Companion
Tips & Strategies

Place a chem bench, generator, and a few fridges for spoiled meat, and park an argy on its platform. You will make far more narcos than you knew was possible. Load the argy and run the narcos back to base to keep you weight down. It's best to put up walls and a bed in case you get killed swinging that tail.
More Brontosaurus Utility Tips
Just found out something really useful about Brontos! You can use them to transport goods a long way, but sometimes you have more than the bronto can carry, so, if you pack your resources on something like a high level parasaur or iguanodon, and put it on the platform saddle, it only takes the Dinos drag weight, not resource weight, allowing you to carry tons of materials at half the weight!
These things can be aggroed on by:
Allosauruses,
Spinos,
Rexes,
Alpha Rexes,
Yutyrannuses,
Carcharos,
Gigas,
Rhynios,
And finally megatheriums that somehow got the insect buff
If it is able to aggro onto a bronto without it aggroing the animal first that means it is aggressive to and will attack any and all other tames.
This also applies to the paracer as in terms of prey the paracer can be aggroed on by the same creatures listed above.
