Check the taming results to see how long it takes to tame the R-Brontosaurus, what effectiveness you'll achieve, and how many bonus levels it gains. Better food means better results.

Below is a breakdown of knockout weapon requirements for the R-Brontosaurus across various creature levels. Space your shots to let torpor accumulate - rapid firing risks killing it before knockout.

To simplify the knockout, immobilize the R-Brontosaurus first with Bear Trap or Large Bear Trap.

Use the narcotic calculator to determine exactly how many Narcotics, Bio Toxin, or Narcoberries you need for the R-Brontosaurus. Your options are Narcotics (40 Torpor), Bio Toxin (80 Torpor, best efficiency), or Narcoberries (7.5 Torpor, cheapest but slowest). With Torpor draining at 0.3/s, don't wait until the bar is nearly empty to apply narcotics.

The real-time timers below help you monitor Torpor drain and Food depletion during the tame. The torpor timer alerts you when narcotics are needed. The starve timer tracks Food depletion for starve-taming, where you let the food bar drop before placing all food at once.

The R-Brontosaurus is a tamable, herbivore creature in ARK: Survival Ascended. Classified under the Variant group.

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.
