The Acrocanthosaurus or simply Acro is a dinosaur in ARK Additions.




Acrocanthosaurus aegis


Early Cretaceous






Appearing much larger than expected, Acrocanthosaurus is a fearsome carnivorous theropod. While larger than a Rex, it's not quite as strong. However, Acros' seem to demonstrate much stronger attacks the smaller their target is. In addition to this, when an Acro begins receiving damage, Acro resort to an interesting tactic which involves revealing the larger sides of their bodies, mitigating the damage they receive considerably. If they remain in this state the Acro seems to undergo a terrifying enraged state... so be careful. Normally being slower than a Rex, this rush of adrenaline will make an Acro frighteningly fast!


Acrocanthosaurus appear to be immune to the typical method of applying narcotics. I have met few survivors which have managed to tame these beasts however, and they claim that you can knockout an Acro by forcing narcotics down its throat as it gains its rush of adrenaline... no thank you... That being said, I have no doubt a tamed Acrocanthosaurus would prove very useful in combat, if its tanking and adrenaline can be utilized properly.


The Acrocanthosaurus can be found on The Island, The Center, Scorched Earth, Ragnarok, Extinction, Valguero, Genesis: Part 1, or Crystal Isles attacking anything in sight. When attacked, the Acrocanthosaurus may position itself into a shield stance, where it will then tank damage. If it takes enough damage (35% of its Health, which is calculated before the tanking modifier), the Acrocanthosaurus will roar in frustration, granting it the Adrenaline! buff, which will allow it to attack faster and do more damage.


The Acrocanthosaurus is a large theropod that possesses a vibrant color pattern and faintly resembles a Giganotosaurus or an Allosaurus. It lumbers over the Rex and the Spino and has a high spine which it uses for defense.

Color Scheme and Regions[]

This section displays the Acrocanthosaurus's natural colors and regions. For demonstration, the regions below are colored red over an albino Acrocanthosaurus. The colored squares shown underneath each region's description are the colors that the Acrocanthosaurus will randomly spawn with to provide an overall range of its natural color scheme. Hover your cursor over a color to display its name and ID.

This information can be used to alter the Acrocanthosaurus's regions by entering cheat SetTargetDinoColor <ColorRegion> <ColorID> in the cheat console. For instance, cheat SetTargetDinoColor 0 6 would color the Acrocanthosaurus's "main body" magenta.

This section describes how to fight against the Acrocanthosaurus.


The Acrocanthosaurus can be a formidable opponent in battle, as it possesses a shield stance as well as the Adrenaline! buff and can easily kill survivors that aren't prepared to fight one. It is advised to fight one mounted, rather than on foot.


Fighting an Acrocanthosaurus with a creature that is of similar or larger drag weight than it will ensure that the creature takes minimal damage. It is also important to note that an Acrocanthosaurus can outrun a survivor while out of shield stance. If necessary, the survivor can inflict enough damage (10% of its Health) in order to enable its shield stance, at which point they can escape.


The Acrocanthosaurus should be fought with a creature, as this reduces the likelihood of a wild Acrocanthosaurus taking enough damage to activate its adrenaline and deal significantly more damage to the survivor and creatures.


If an Acrocanthosaurus successfully activates its adrenaline without being killed, it becomes a force to be reckoned with, doing almost double its original Melee Damage. The survivor should take caution when on foot or on a creature with a lower drag weight, as an Acrocanthosaurus can outrun a survivor while out of shield stance. It also does more damage to targets smaller than it with its stomp. Tamed Acrocanthosaurus pose a greater threat, as it becomes difficult to kill the rider when the Acrocanthosaurus enters shield stance. The shield bash attack of an Acrocanthosaurus in shield stance can also knock back a large amount of creatures, so survivors should be wary of environmental hazards such as cliffs.

Wild Acrocanthosaurus tend to spawn in groups of 2-3. These groups often consist of opposing genders, enabling the Acrocanthosaurus's mate boost.


Fighting the Acrocanthosaurus with a strong creature that has higher drag weight will make the process of killing one much easier. When a wild or riderless Acrocanthosaurus enters shield stance, the survivor can stop attacking in order to get it to exit the stance and prevent it from being able to activating its adrenaline.


Preferred Food[]

Taming Method[]

Since the Acrocanthosaurus is immune to ranged tranquilizers, the only way to render one unconscious is by feeding it Narcoberries, Narcotic, or Bio Toxin whenever it roars in frustration. Place the Narcotic in the last slot of the hotbar, run up inside the mouth of the Acrocanthosaurus, and, aiming for the top jaw, use E to feed them to the Acrocanthosaurus. It is recommended to use a Fabricated Sniper Rifle, as this allows the survivor to count the shots needed to put the Acrocanthosaurus into its shield stance and the shots needed for it to activate its adrenaline.



  • Left - This key triggers a simple bite. When the adrenaline is active, the speed of this attack is increased.
  • Right - This key activates its shield stance. When enough damage is taken in this stance (10% of its Health), the Acrocanthosaurus will roar, activating its adrenaline. Using the Left in this stance will trigger a shield bash, which can damage Metal-tier structures.
  • C - This key triggers a side stomp. The damage of this attack is multiplied by a target's drag weight relative to the Acrocanthosaurus's drag weight. When the adrenaline is active, the Acrocanthosaurus will perform 3 stomps instead of 1.
  • Ctrl - This key triggers a roar.


Tank - While in its shield stance, Acrocanthosaurus will be able to tank damage. While it is taking damage in this state, it will build up its adrenaline. Once this is full, it receives a 35 second buff which regenerates 0.2% Health per second, and a boost to Melee Damage, resistance, and Movement Speed.

Alpha Hunter - Acrocanthosaurus can take the hits of Alpha creatures when utilizing its shield stance and can easily kill lower level ones. However, Acrocanthosaurus are at risk when facing higher level Alpha Rexes and should be leveled in Health and Melee Damage to ensure victory.

Bullet Sponge - The shield stance is an efficient way to soak Auto Turrets and other ranged attacks, as it transforms the Acrocanthosaurus a living shield for survivors and creatures, including the rider. The Acrocanthosaurus may also activate its adrenaline if it takes enough, which allows some time to back off and regain Health or bring in other creatures. While in its shield stance, the Acrocanthosaurus is also able to damage Metal-tier structures, which makes it incredibly useful in raids when leveled in Health and Melee Damage.

Boss Army - If used properly, an Acrocanthosaurus can be used to take on the bosses of The Island and Scorched Earth. When an Acrocanthosaurus activates its adrenaline, they gain an increase in Health regeneration, attack speed, and Melee Damage. This ability can prove to be critical in a boss battle, though the survivor should always have backup creatures. Acrocanthosaurus are incredibly effective against the Broodmother in particular, as their immunity to Torpidity means they aren't knocked unconscious during the fight, and the broodmother's attacks have the potential to quickly put it into adrenaline to allow you to deal increased damage. If attempting this strategy, well bred, mate boosted Acrocanthosaurus with good saddles should be used, along with Daedon to help heal the damage taken in order to enter adrenaline. The shield stance may mitigate some damage, but it isn't nearly as much of a reduction as a Megatherium's insect killer buff.

Golem Fighter - Since the shield bash of the Acrocanthosaurus can damage Stone-tier structures, this particular attack faces no damage reduction when used against Rock Elementals. This can prove particularly useful on Scorched Earth.



For information pertaining specifically to the real-world Acrocanthosaurus, see the relevant Wikipedia article.

  • Acrocanthosaurus aegis roughly translates to "high-spined lizard shield."
  • Imprinting increases the Acrocanthosaurus's normal Movement Speed by 20%, but this has no effect on the Movement Speed while its adrenaline is active.
  • Prior to January 11, 2020, Acrocanthosaurus could not enter the Tek Cave after the prohibition of Cryopods. This has been fixed.
