Basic Info[edit | edit source]
Dossier[edit | edit source]
The Yutyrannus saevus is believed to be related to the Tyrannosaurus rex, but it is noticeably different upon first glance. Feathered creatures are not necessarily viewed as dangerous predators in the same light as other theropods. However, the Yutyrannus strikes fear into even the Island's most skilled hunters.
There are few wild predators that are able to pack-hunt alongside the generally hostile Carnotaurus, like the Yutyrannus does, with such ease. It is also the only creature I've seen to consistently induce a state of panic in opponents with its roar. Upon hearing it, most creatures in the area will flee for safety.
A domesticated Yutyrannus can be a powerful offensive or defensive addition to war parties. With its mighty roar, it can induce fear in opposing creatures. Meanwhile, Yutyrannus can be trained to develop a confidence-boosting Battle-Cry which counteracts enemy attempts to induce fear, while also bolstering the resolve of allies, and may even draw wild Carnotaurus to its aid. These unique "leadership" qualities make the Yutyrannus a versatile, and at times, a necessary creature to have on your side during large-scale confrontations!
Behavior[edit | edit source]
The Yutyrannus is highly aggressive, killing anything it comes across, excluding Carnos. Approach with caution, as the Yutyrannus has a roar ability that can make tamed mounts become unsettled and bolt, regardless of commands, often taking the mounted rider with it.
Appearance[edit | edit source]
Yutyrannus is a large carnivorous dinosaur possessing a long head with a low ridge across its snout and a pair of horns above its eyes. Its body is covered in thick downy feathers and unlike its larger relative, the Rex, it has long arms with three clawed fingers.
Color Scheme and Regions[edit | edit source]
This section displays the Yutyrannus's natural colors and regions. For demonstration, the regions below are colored red over an albino Yutyrannus. The colored squares shown underneath each region's description are the colors that the Yutyrannus 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>.
cheat SetTargetDinoColor 0 6 would color the Yutyrannus's "main body" magenta.

Base Stats and Growth[edit | edit source]
Note that creatures will have different stats in Survival of the Fittest
|Attribute||Amount at Level 1||Increase per point||Taming Bonus|
1Percentages are based on the value of the stat the moment the creature was tamed (after taming effectiveness)
2The absolute Base Damage is shown here instead of the percentage.
3Wild creatures do not level up movement speed
4Torpidity increases every level on wild creatures, but can not be increased once they are tamed.
|Movement Type||Base Speed||Sprinting|
- These are the base speeds of the creature at 100% Movement Speed
- For a comparison of the speeds of all creatures, see Base Creature Speeds
|Attack Type||Projectile Values||Torpor Values|
|Impulse||Radius||Base||Mult||Duration||Damage Mult||Amount||Duration||Damage Mult||Amount|
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.
The stat-calculator does not work in the mobile-view, see here for alternatives: Apps
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.
Combat[edit | edit source]
General[edit | edit source]
Never engage the Yutyrannus head on. Its roar will cause all dinos, except for Giganotosaurus, Rex, Spino, Wyvern, Bronto, Rock Elemental, Alpha Creatures, Bosses, or water creatures, tamed or untamed, to run away from it, even if being ridden. Player movement speed needs to be at least 181% to outrun it.
Strategy[edit | edit source]
Cliffs- Use a fast mount that can outrun the Yutyrannus. Get the Yutyrannus at the bottom of a steep cliff, get on top of the outcropping, and start shooting with your preferred tranq.
Fliers- Use a Tapejara or a Quetzal to be high above the Yutyrannus and shoot it with your preferred tranq.
Icebergs- Lure the Yutyrannus into water. Using a flyer works best, just quickly attack it and go land on a nearby iceberg to where he is forced to swim and can't climb up. The Yutyrannus will however ignore the iceberg's physics and still attack you. ( And even though this is smart, if any animal is knocked unconscious in water, depending on its size, they would sink and drown in the water quickly, so think carefully.)
On Foot- Lure towards a wall (2 high) and tranq from other side. Yutyrannus has not been known to roar or crawl over.
Kaprosuchus will also work.
Weaponry[edit | edit source]
Any long distance weapon.
Dangers[edit | edit source]
Roar ability will call wild Carnos to fight for the creature as well as scare your dinos into an uncontrollable retreat. Also, many dinos will be near the Yutyrannus such as dire wolves, Carnos, etc. Bring protection dinos to keep it and you alive from these outside threats.
Weakness[edit | edit source]
High Ground. If your mount is too high for the Yutyrannus, you will be out of range of its roar. If your flying mount is high enough, the fear roar will affect but it will not be able to attack you as the roar does not force your flying mount to fly down.
Having an agile mount such as Dire Wolf can be effectively avoiding its roar by simply running in the circle.
Taming[edit | edit source]
For general infos about domesticating a wild creature see Taming.
KO Strategy[edit | edit source]
Use a fast mount that can outrun the Yutyrannus to a steep cliff, get on top, and start shooting with your preferred Tranq.
Use a Tapejara or a Quetzal to be high above the Yutyrannus and shoot it with your preferred tranq. Land to regain stamina sooner than you normally would - if its fear roar hits you while you are low on stamina your bird will sprint until it's exhausted, potentially forcing you to land in an unsafe location.
- Bronto strategy
One way to tame one is to stand on a bronto (make sure to set it on passive and you can usually ignore the carnos) with a fast mount prefferably a bary or thyla. Shoot the yuty from the back of the bronto, then when it starts running set the bronto to nuetral (so the carnos don't kill it while you tame the yutyrannus) and run down the yuty (it will not fear roar when running) with your bary or thyla (these are most reccomended because you will probably be constantly under attack by wolves and daeodons) and shoot the yuty while riding the bary/thyla.
Build a cage out of stone foundations (e.g. 2x3) with stone doorframes as walls. Place ramps at one side so you can lure the Yutyrannus into the cage by using a flyer or simply by running. Then you can easily shoot it with Tranqs without putting yourself in danger. You should kill the Carnos surrounding the Yutyrannus first.

Utility[edit | edit source]
Roles[edit | edit source]
Troop support: The courage roar (C, , ) of Yutyrannus temporarily boosts the attack damage allied creatures inflict by 25%, and reduces incoming damage they take by 20% each. This can be very useful in massive battles or when fighting bosses.
Intimidation: The fear inducing roar (Rmb, , ) of Yutyrannus also terrifies enemy creatures, even when mounted by a player. This leaves them weak to attack from other animals and players in the tribe. The affected creatures will receive a debuff increasing damage taken and reducing damage done by up to 50% each. At full fear, the terrified creature will flee and not respond to commands. Additionally, a roaring Yutyrannus is a terrifying sight, and may even scare off other survivors!
The following creatures that attack, defend themselves or fight back instead of running after hearing the Yutyrannus’ Fear Roar:
- Tek Stegosaurus
- Reaper King
- Reaper Queen
- Rock Drake
The following creatures ignore the Yutyrannus' Fear Roar, including all Alpha Creatures, and all Bosses and their minions:
Fertilizer Gathering: Once a wild creature has reached the full fear effect, it will not only flee but it will also defecate in the process. The player is then free to dismount and gather the Feces. Inducing fear on a group of weak creatures such as Dilos can easily yield 5-10 feces.
Hunting: Good damage output and the ability to make wild Carnos fight on your side, when used the boosting roar on them, makes the Yutyrannus one of the best prey hunter and versatile mount in the game. Also, the knock-back from the roar and bite attack makes it unable to be hit by small to mid-size creatures.
Taunt: Corrupted creatures on the DLC Extinction are taunted by the 'Fear' roar, causing them to aggro onto the Yutyrannus instead of running. Affected creatures are still debuffed to take increased damage and deal reduced damage. This can be useful in defense objectives to pull hostiles away from undesired targets.
Transport: Like all the other massive creatures, Yutyrannus can carry a lot.
War Mount: Yutyrannus itself does decent amount of damage. However, a fight with other large carnivore dinosaur is best to prevent as they ignore the intimidation roar. Due to the lengthy attack animation that Yutyrannus has, it's not strange to lose a fight against a Rex, or a Spino.
Extraordinary Kibble Production: Although the Yutyrannus prefers extraordinary kibble itself, its eggs are the only passively-obtained eggs that are used for extraordinary kibble as of patch v294.101. (Technically Golden Hesperornis eggs still do too but acquiring these can be obnoxious.) This can make Yutyrannus the only creature ever needed for kibbles since extraordinary kibble is effective for taming any kibble-tamed creature, though using extraordinary kibble on much lesser creatures can be very taxing. Do note that if you are going for a Yutyrannus egg farm, only low-level Yutyrannus are required.

Notes/Trivia[edit | edit source]
For information pertaining specifically to the real-world Yutyrannus, see the relevant Wikipedia article
- Dino Dossier revealed on 04/10/2017.
- Yutyrannus Saevus roughly translates into "Savage Feathered Tyrant."
- The dossier notes states that the Yutyrannus is one of the few creatures that can hunt alongside Carnotaurus with ease.
- Yutyrannus's intimidating roar also works on wild or enemy Yutyrannus.
- Trailer's Yutyrannus's roar is different compared to the game.
- Might be a bug, if you knock any creatures unconscious while the creature is feared by your Yutyrannus, after you tame it, your new creature will attack your Yutyrannus all the time.
- Sometimes Alpha Carnos spawn near the Yutyrannus.
- Yutyrannus's courage roar works on nearby allied water creatures.
- The Carnotaurus army sometimes betray the Yutyrannus.
- An Alpha Carno can't hurt a wild Yutyrannus while attacking it.
- Contrary to popular belief, Yutyrannus's roar does NOT summon Carnotaurus and Alpha Carnotaurus in the same manner as bosses summon minions. It is set in its spawner to spawn with a guaranteed pack of three carnotaurus minions, with ONE of these Carnotaurus having a slight chance to be an Alpha Carnotaurus instead of a normal one (this same "chance" method is how all alphas spawn). This is all evidenced in the Devkit itself.
- Yutyrannus has replaced the Rex as the largest dinosaur that can fit in Dinosaur Gate.
- Yutyrannus can knock over trees much like the islands larger predators (i.e Rexes, Spinos, and Giganotosaurus), but like the Allosaurus it doesn't deal trample damage to small creatures.
- Yutyrannus's fear doesn't affect bosses or their minions.
- If the player's mount is affected by the Yutyrannus's roar, the mount will be encircled by purple streaks, and a circular dial is shown at the top (in addition to the cowardice icon in the upper right). The purple filled section indicates the effect level (which will slowly decrease). If it exceeds 100% (which normally happens when the ride is hit with another roar while the first one was still active) the mount will flee uncontrollably.
- Prior to the major patch update of ARK: Homestead, the kibble used to perfectly tame a Yutyrannus is considered by many to be a huge hassle due to the low drop rate of Golden Hesperonis Egg. With the patch however, that is possible assuming the survivor who wants to tame it has planned access to Wyvern Egg or Rock Drake Egg
- Interestingly, Yutyrannus have 2 extra yellowish teeth on its upper jaw, it will be a lot easier to see while it's unconscious.
- Usually a large creature that won't met Yutyrannus in its map can be scared by Yutyrannus, this include Reapers, Basilisk, Rock Drake etc.
- Strangely, Tamed Yutyrannus will play its startle animation when its owner takes fall damage.
