The R-Brontosaurus is a tamable, herbivore creature in ARK: Survival Ascended. Classified under the Variant group. Starting at 2,209 Health, it's a proper tank. Melee starts at 105% - decent hitting power that scales with level-ups. Stamina sits at 240 base, providing moderate endurance. It carries 1600 base Weight - an enormous weight pool. The R-Brontosaurus is a knockout tame: apply enough torpor to knock it out, then place food in its inventory. For best results, use Exceptional Kibble - it gives the highest taming efficiency. Once tamed, the R-Brontosaurus pulls double duty as both a capable resource harvester and pack animal. Breeding produces fertilized eggs that hatch within a 28°C–31°C temperature window. Killing a wild R-Brontosaurus yields 22 base XP. It can be cloned at a Cloning Chamber for 0.79 Element plus 0.01 Element per level.
