The Tyrannosaurus (tye-RAN-uh-SAWR-us), or simply Rex, is one of the dinosaurs in ARK: Survival Evolved. The Tyrannosaurus is a huge, bulky predator that dominates virtually all of the island. It has considerably more health and stamina compared to Spinosaurus, but lacks the attack speed that Spinosaurus has. They are also incredibly slow in water, making them vulnerable to attack from below, but they make up for these drawbacks with sheer size and strength.

Basic Info[edit | edit source]
Dossier[edit | edit source]
One of the deadliest creatures on the Island, Tyrannosaurus dominum is a killing machine.
Active mostly when hunting for food, this formidable predator can be spotted in forests or grasslands chasing down its prey and devouring them with its incredibly strong jaws. I've seen few creatures on the Island that can contest the Tyrannosaurus for dominance. It is pure power, from its bite, to its stomp, to its tail.It is not able to intimidate every foe for with its roar, but upon hearing it, it even scare the poop out of you, quite literally.
Despite being a different sub-species of Tyrannosaurus, everyone I've met still refers to them as a "Rex" or a "T-Rex". I've long since stopped trying to convince anyone, especially the few who I've encountered wearing Tyrannosaurus teeth as necklaces.
Taming a Tyrannosaurus is without a doubt the goal for any warlord or warring tribe. Tyrannosaurus is a fierce battle companion. There is a reason Tyrannosaurus is considered the king of dinosaurs (or in this genus, the "lord"). Any tribe that manages to tame one has almost nothing to fear.
Behavior[edit | edit source]
Highly aggressive, Tyrannosaurus will attack any living thing in sight. However, unlike most other predators within the game, they seem to prefer other, larger prey to humans (players.) They are often seen ignoring smaller potential prey when larger ones are present. They're extremely bulky, having nearly double the health of Spinosaurus of the same level. They also possess surprisingly good stamina for their size, of which is also greater than that of any same-leveled Spinosaurus. What Tyrannosaurus' lack in attacking speed (when compared to a Spinosaurus) they make up for in sheer stamina and health. As stated in the dossier, it is considered the ultimate predator present on the island, those who tame them are to be feared like no other.
Appearance[edit | edit source]
T. dominum is an exceptionally large (and often colorful) theropod dinosaur found on the island. They are covered in small, circular scales that are often interrupted with large osteoderms. Their underbelly, however, is smooth and tan. Along their neck and back there is a large ridge of hard bony plates that may be used to protect their vertebrae from the jaws of other carnivores (including other T. dominum.) They have proportionately long legs that end in three thick, padded toes, each decorated with one large claw. T. dominum regularly exceed fifty feet in length, however, they possess disproportionately small arms. Strangely, these arms are heavily muscled and extremely thick. When tamed and ridden no carnivores except for other Rexes, Giganotosaurus, Yutyrannus and Therizinosaurus will attack you if you don't attack them first, which makes it easy to travel with the rex without being hunted by other dinosaurs.
Color Scheme and Regions
This section displays the Rex's natural colors and regions. For demonstration, the regions below are colored red over an albino Rex. The colored squares shown underneath each region's description are the colors that the Rex 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.
Server admins can use this region information in the Console Command "cheat SetTargetDinoColor <ColorRegion> <ColorID>".
For example, "cheat SetTargetDinoColor 0 6" would color the Rex's "body" magenta.

Drops[edit | edit source]
- Guaranteed Special Loot
Breeding[edit | edit source]
One of the more difficult dinos to breed in captivity, due to difficulty in maintaining proper egg temperatures and the long period of hand feeding the infant. Recommend at least 2 Air Conditioners and multiple standing torches to aid in maintaining the egg at the proper temperature. Between monitoring the egg during incubation and hand feeding the infant, it is a 8-9 hour commitment to get the baby to the stage where it will eat out of a feeding trough.
- Temperature: 85-95 degrees F / 29 - 35 degrees C (not accounting for insulation)
- Incubation: Approximately 5 hours
- Maturation: Approximately 3 days 20 hours and 30 minutes.
Base Stats and Growth[edit | edit source]
Note that creatures will have different stats in Survival of the Fittest

Wild Stats Level-up
Type in values of a wild creature to see on which stats it's emphasized. Green values on a high-level creature are very good for breeding. If you have already tamed your creature you can try to recover the breeding-stats with an external tool.
Note that after the creature is tamed it gets bonuses on some stats depending on the taming effectiveness. This makes it hard to retrieve the levels on a tamed creature, so this tool is only for wild ones, but gives a first impression, how well the stats are distributed.
Taming[edit | edit source]
For general infos about domesticating a wild creature see Taming.
KO Strategy[edit | edit source]
Since Rexes are relatively fast and incredibly strong, trying to tame a Rex solo on flat ground is almost never a good idea. Bring a few friends and shoot Tranq Arrows at its head. Beware that it too will flee once torpor gets low.
Common strategies include:
- Build a tower 10 Stone Pillars high with a ceiling on top. Lure the Rex to it while riding a flying mount, then land on your tower and shoot tranquilizers at it.
- Find a Rex that spawned near a cliff. Quite a lot of Rexes spawn in the cove on the southeastern shores, sometimes 4 at a time. Stand on top of the cliff and shoot Tranq Arrows at its head - it will usually stand still while trying to reach you. This method makes it relatively easy to tame a Rex solo. You can also aggro the Rex from a distance and steer it to a cliff while riding a fast mount, such as a Raptor.
- If you can't find a cliff, bring a friend with a Tapejara, Pteranodon, Argentavis or Quetzal. One player flies the mount and carries the other player, which then shoots Tranq Arrows at the head of the Rex. Be careful to not let your mount run out of stamina, or the Rex will most likely kill all three of you when you go down!
- Bring one or more tanks set to passive. The Rex will usually attack your pet while you can shoot Tranq Arrows at it from a distance.
- Another strategy is to find an area with large amounts of prey animals, and lure the Rex towards it, then, while it is attacking or eating, shoot tranq arrows or darts at it, avoiding its agro by running towards another prey animal, and repeating the process until the Rex goes down. However, neutral prey, such as Triceratops will continue attacking, which will lower effectiveness, so be prepared to kill the prey as well.
- Lure a rex into a behemoth gate cage and use your friend's flyer (Don't use pteros, if you try and shoot it will shoot them) to start shooting it down and you got yourself a safe spot :)
- Ride a raptor oriented for stamina, speed, and enough carry weight. A raptor outruns a Rex so run forward, turn to the side, shoot at its head, then turn and resume running again. Each pause to shoot will allow the raptor to regen stamina while you take the time to line up a good shot. As well using rocks and other terrain features to kite it around help greatly. It will eventually run which is easy to catch on a raptor.
- Create a taming boat that consists of STONE so the rex won't break it and make the area the rex will be out of stone doorways.(ALSO MAKE SURE TO COVER THE WOOD PART OF THE RAFT) This allows you to shoot it with tranqs and it won't get out. Make a ramp that leads into the trap. Once your taming raft is made and ready park it on the shore close to the rex you want to tame, make sure you're faster than the rex, and agro it up the ramp. Into the trap and run through the gaps in the doorways and tranq away! Alternatively, if you wall off the portion of the raft where you stand to drive, you can drive the still-awake rex to your base and tame it in safety there.

Combat[edit | edit source]
This section describes how to fight against the Rex.
General[edit | edit source]
The Rex can deal massive amounts of damage, and is fairly fast and tanky. Try hitting it with a Chain Bola fired preferably from a ballista on a platform saddle, then shooting it with a Longneck Rifle, with bullets if you want to kill it, or with Tranq Darts if you want to tame it. If you don't have a Chain Bola available, try getting it stuck between large rocks, as it is large enough to knock down trees by just walking.
Strategy[edit | edit source]
Player base sprint speed is faster than that of a wild Rex. It is possible to kite the Rex and do damage with ranged weaponry. If you get attacked by a Rex, try to find large rocks to get it stuck, or if you have a flyer nearby, get on that and get above a cliff, and shoot it from the cliff.
Also, make sure the Rex is not glowing red. If it is, that's an Alpha Rex!
An effective strategy is, because of their terrible swimming speed, is to use a raft: drive it far enough away to where you can still shoot it and it doesn’t aggro to anything else, and hop off and shoot it. Continue this process until it is dead. NOTE: when using this strategy, don’t go to far out into the ocean, as you could aggro a Leedsichthys.
An additional note: Following this strategy, if there happens to be some Megalodon for example between a connection from ocean to a river with some deep, they may get aggro against a swimming Rex. Don't know if this is a bug, because a Rex should be ignored from most predators.
Weaponry[edit | edit source]
Make sure that you have at least a Crossbow or Longneck Rifle. Fabricated weapons such as the Assault Rifle or the Rocket Launcher work best, but would be a waste of resources that would be better for raiding, or defense.
Dangers[edit | edit source]
Tyrannosaurus has a balanced amount of the primary stats, i.e. damage, health, and speed. The Rex is not to be trifled with in the early game. If a player has low stamina (or is low level), the player could run out of stamina and the Rex could easily catch up. Getting it stuck between trees is useless, as it destroys trees as it walks.
Weakness[edit | edit source]
Rex will agro on anything except small creatures like a Dodo, Dilo, Compy etc. If you find a Carbonemys, Rex will agro on it, allowing you to escape. If you need to escape from a wild Rex, base player sprint speed is higher than that of a wild Rex, so you can outrun one on foot. However, small obstacles in your path can allow it to catch up, as the Rex could easily walk over something a player would have to go around. By doing this, you can also run into a pack of Raptors, Carnos and other creatures that can kill you, so beware of them!
Utility[edit | edit source]
Roles[edit | edit source]
- Tank: Possessing a huge health pool, the Rex also inflicts greater damage and moves much faster when compared to bulkier tanks such as the Brontosaurus. (Level up Health and Melee Damage)
- Hunter: One of the best creatures in the game at harvesting meat and other resources from carcasses, the Rex has little to fear in the wilds. (Level up Melee Damage and Health)
- Damage: While still nowhere near that of Giganotosaurus, the Rex's damage output is incredibly high, and its durability is also useful for long skirmishes. (Level up Melee Damage and Health)
- Transport: Decent speed and carry-weight make it decent for transporting goods, very few are dumb enough to challenge a Rex convoy. (Level up Weight, Movement Speed, and Stamina)
- Intimidation Tame: With its high volume of roar and large overpowering appearance, the Tyrannosaurus is by far the best way to ward off anyone who dares attack your mount. Furthermore with its roar ability to cause lower-leveled wild/non-allied dino/survivors to defecate makes it even more intimidating.
- Raid Boss Tank/DPS: Rexes are among the best creature to use for battles against the bosses such as Broodmother Lysrix and the Megapithecus. Their massive health pool and high damage can allow a horde of them to hold aggro on a boss for a very long time. Coupled with a Yutyrannus providing a courage roar and a few Daeodon providing healing, it's possible for them to take down a boss without requiring guns and ammunition...but you should bring those with you, just in case. (Level mostly Health and some Melee Damage.)
Collectibles[edit | edit source]
|Raw Prime Meat||★★★★★|
Roar [edit | edit source]
- Causes non-allies under a certain dragweight to defecate with a small stun/interrupt on creatures both tamed and wild. Does not stun players but causes them to poop.
- The stun/interrupt will cause affected flyers to be grounded.
- Victims have a cooldown in order to prevent 'pooplocking'.
- Does not work on anything above the Rex's level.
Ride a T-Rex.
- Riding a Rex will award the "Rex Rider" achievement.
Notes/Trivia[edit | edit source]
For information pertaining specifically to the real-world Rex, see the relevant Wikipedia article
- Its full name, Tyrannosaurus dominum, translates to "Lord of the Tyrant Lizards".
- To call it a T. rex would be scientifically incorrect, considering Tyrannosaurus rex and Tyrannosaurus dominum are two separate species of the same genus. However, the official dossier admits that most people call it by the more popular name.
- Tyrannosaurus dominum is, on average, much larger than any known Tyrannosaurus rex fossils. To put this in perspective, a regular sized human is about as high as T. rex' knee, while the player character barely reaches the ankle of T. dominum.
- T-Dominum and T-Rex are both scientifically incorrect spellings of the two dinosaurs. Tyrannosaurus is the genus name, and therefore it's capitalized. dominum and rex are the species' names, and are therefore not capitalized. Because the name Tyrannosaurus is being abbreviated, the correct spelling is T. dominum or T. rex.
- Rexes will often get themselves seriously injured or even killed by attacking too many herbivores at once. Curiously enough, a player-controlled mounted Rex can easily take on many enemies at once, if it manages to keep all enemies in front of it, near its mouth. Unridden Rexes are unable to employ this strategy, causing them to get surrounded and unable to attack.
- As of v260, the Rex requires a Behemoth Gateway; it can no longer fit into a smaller gate.
- Rexes, like other large animals, don't take bonus damage from head shots. Shoot for body.
- Riders beware: A sprinting Rex damages anything it steps on. This means knocking down trees, instantly crushing the occasional dodo, and sometimes provoking herd attacks that could actually threaten your mount if you're not ready for it.
- In the Survivor Profile, the devs misspelled Tyrannosaurus, they instead wrote "Tyranosaurus".
- T. dominum's meaning is similiar to that of Indominus rex from the movie Jurassic World.
- The Rex received a major update for TLC Phase 1 on the 10th February 2018 on PC (consoles on the 23rd) with an appearance overhaul, a new ability to stun lower-levelled wild/non-allied dinos and survivors by forcing them to defecate with a roar, and better climbing of rocks and hills.
- Patch 278.0 removed PaintRegion 3 (former Back), Patch 278.2 added PaintRegion 4 as new Back therefor making previously obtained colormutations in those regions unaccesable
