If you are relatively new to Ark, it would be better to tame a paracer than a bronto simply because it’s easier to move around. Even though it has lower stats in health and weight, it still has an adequate amount of both. Stamina will be higher as it is smaller in comparison. Putting levels in health, weight, and melee is best, then maybe put a few in stamina and/or movement speed to make it a better travel companion. Overall, this is an adequate pack animal that is more compact and easy to travel with if you are in early mid game.
