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.
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! Arrow so people can see this!
It would be good if this dinosaur gets a new attack, like a stomp, because, a tail that whips opponents gets boring. And a stomp makes sense due to its large size. Hopefully people agree, and those who see this suggest it to wildcard.
