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

With 250 base Stamina, the R-Allosaurus has average stamina. Melee starts at 105% - decent hitting power that scales with level-ups. Health-wise, the R-Allosaurus sits at 611 base, making it impressively tough. A base Weight of 380 means generous inventory space.

The R-Allosaurus is a knockout tame: apply enough torpor to knock it out, then place food in its inventory. Superior Kibble is the most effective food for taming, offering the highest affinity per feeding.

After taming, the R-Allosaurus is valued for its harvesting efficiency, collecting key resources faster than most tools. Breeding produces fertilized eggs that hatch within a 26°C–32°C temperature window. Defeating one in the wild grants 18 base XP. It can be cloned at a Cloning Chamber for 0.53 Element plus 0.01 Element per level.
