The Rhyniognatha (ry-neo-na-tha) is the last new creature in ARK: Survival Evolved.
It was submitted as a competitor in February 2023 and its victory was announced in Community Crunch 348[1].
Basic Info
The Rhyniognatha is only available on The Island and Lost Island.
Dossier
This section is intended to be an exact copy of what the survivor Helena Walker, the author of the dossiers, has written. There may be some discrepancies between this text and the in-game creature.

- Wild
I swear, every new creature I come across here makes me more sure they've all had their genes tampered with. I know I'm right about this. Take this monster bug I'm calling 'Rhyniognatha antiquagenitor' -- big enough to headline a horror flick, but still light enough to fly and skate across water.
Would you believe it also makes a weirdly useful, quick-hardening resin with a variety of uses? It can thicken up its shell for a defensive boost, spray hard bullet-like globs, or squirt soft globs that harden on impact to gum up incoming predators!
- Domesticated
These overgrown earwigs are just what you need to level up your tribe's aerial defenses! And here's a tip: if you crush up the right Arthropleura, you'll get an enzyme that makes Rhyniognatha glue as TEK-disruptive as Dinopithecus dung. Plus this bug can glue itself to creatures or cargo and carry things around your base!
That said, Rhyniognatha-raising isn't for the squeamish... Their males have a pheromone that invites egg-laying females to use them as hosts. Harvest that pheromone, and you can mark any creature for the female to lay her eggs on. The host then incubates a new generation of larvae that can reap its best traits in the process.
If some poor beast gets eggs laid on it by accident, you might still be able to save it by popping it in a cryopod and freezing out the larvae.
Appearance
Color Scheme and Regions
This section displays the Rhyniognatha's natural colors and regions. For demonstration, the regions below are colored red over an albino Rhyniognatha. The colored squares shown underneath each region's description are the colors that the Rhyniognatha 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 Rhyniognatha's regions by entering cheat SetTargetDinoColor <ColorRegion> <ColorID>
in the cheat console. For instance, cheat SetTargetDinoColor 0 6
would color the Rhyniognatha's "body main" magenta.

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.[2]
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.
Cloning
The Rhyniognatha can be cloned with the Cloning Chamber.

Combat
This section describes how to fight against the Rhyniognatha.
Using Megatherium can be an effective strategy as they are strong against bugs, such as the Rhyniognatha.
If on foot, you can use Harpoon Launcher with Net Projectile ammo to immobilise it, followed up with a Pump-Action Shotgun to finish it off.
Drops
On official settings only the male drops Rhyniognatha pheromone, required for getting a host creature impregnated
Taming
Overview
Wild Rhyniognatha cannot be tamed, and domesticated Rhyniognatha cannot be bred. In order to get a tamed Rhyniognatha, a tamed creature must be impreganted by a female Rhyniognatha and imprint on the baby (the creature will be killed in the process when the creature is born, so only use ones you are willing to sacrifice).
Impregnation
In order to do this, you must find Rhyniognatha Pheromone dropped by a male Rhyniognatha. Once obtained, hold onto the Pheromone until you find a female Rhyniognatha. Weaken the female Rhyniognatha until its below 10% HP, and it may try to impregnate the creature if you had used the pheromone on it (there will be an effect surrounding it while the pheromone is in use).
Only creatures with a drag weight of 300 and above can be used for impregnation, as a result some creatures we would expect to be able to use based on visual size are not suitable because of their low drag weight like stegosaur and megatherium. The best creatures to use are anything with a drag weight above 900 which all give 100% Host Size. In this regard there is no difference between using a Bronto or a Giga or a Carcha, the difference comes down to what stats the host Dino has and which stats are randomly inherited from the host upon impregnation; Therefore it is possible to use multiple cloned Dino's with the same female Rhyniognatha, and have different stats and levels as a result of the random stat selection
After impregnating the creature, it will slowly drift off. You can utilize Transponder Node and its Tracker to track down the creature while its slowly flying away passively, or simply trap them in a wide open cage with exits that your creature can safely exit. You cannot use
Cryopod on the creature as that will remove the embryo inside the creature, so instead you will need to move them either the long way back, or through other flying methods like
Hover Skiff or where applicable,
Tek Teleporter.
It is possible to use a large trap like 8 stone behemoth gates in a row to use a female Rhyniognatha to get multiple tames impregnated with the same rhynio, having a behemoth gate at each end and in the middle to be able to close the rhynio in while you move the impregante Dino out and put another one in its place
Pregnancy
Once impregnated, the gestation period begins, during which the growing embryo can be seen on the creature itself when focusing the camera on it while dismounted. Pregnancy lasts until the host/surrogate dinosaur dies or the player chooses to end the pregnancy. Prolonging the pregnancy allows time to meet the unusual food cravings that function similarly to imprinting. (note that the host's health will drain at a constant rate as will it's food, the health and food lost is percentage based and in line with how far along the gestation of the larvae is. The host will hit zero health upon time of birth)
Once the period ends, the baby forcefully 'ejects' from the dinosaur killing it in the process and landing a few distance where the dinosaur died.
Baby
Upon bursting out from the host, the Rhynio will be juvenile at 30% maturation. It will not be hostile and can be claimed by any player. They can be raised just like any other omnivore without issue. You can feed it with some Berries for 20 Food points or with
Raw Meat for 50 Food points.
Once your Rhyniognatha has reached adult age, even though they cannot be bred, a Cloning Chamber is a viable option for producing more Rhyniognathas, although cloned Rhyniognathas will not receive the benefits of imprint bonuses.
Post-birth stats
The stats of the baby Rhyniognatha will be inherited from the mother and host dino similar to how it works in the case of regular breeding, inheriting a mix of stat points from either "parent". However, these stat points will not be inherited at 100%. There are three values that affect how much of a "parent's" stat is transferred to the baby:
- Craving Satisfaction starts at 0% with no cravings fulfilled and increases by 20% per craving to a max of 100%. This means the host creature will only have a maximum of 5 cravings before the Rhyniognatha baby hatches.
- Host Size Quality is dependent on the drag weight of the creature, this determines how much of the chosen hosts stats are transferred onto the baby. The smallest drag weight creature that can be fed a pheromone and used for pregnancy is 300, giving 25% host size. This rises up to 100% host size quality for anything above 900 drag weight that can be force fed food.
- Egg Quality depends on the level of the wild female Rhyniognatha used. This starts at 25% for a base level rising up to 100% for a max level, with each level increment raising the egg quality up by 2.5%.
Depending on if the stat gets inherited from the mother Rhynio or the host creature, the stat points transferred can be calculated using the following two formulas:
[Baby Stat] = [Host Stat] × (<Craving Satisfaction %> × 75% + 25%) × <Host Size Quality %> × <Egg Quality %> [Baby Stat] = [Mother Stat] × (<Craving Satisfaction %> × 75% + 25%)
where all percentage values need to be in decimal form (i.e. 25% = .25). In order to get perfect stat transfer to the baby, all of these qualities need to be at 100% at the time of its birth. They can be seen in game by enabling the extended HUD (default key 'H' on PC) while looking at the impregnated dino.
With a Trike host the max stat transfer possible is 25%, 78% with a Rex and 100% with a Giga. The higher the drag weight the surrogate dinosaur is, the higher the percentage of the surrogate parents chosen stats are transferred to the baby, with Giga, Carcha, Bronto, and Megachelon being the best options.
Rhyniognatha babies can also inherit any mutation stats and color from the surrogate parents, making it possible in raising a Rhyniognatha with a 254 or 255 stat in either health or melee. Surrogate parents which were raised rather than tamed in the wild will not have the stat enhanced by Mutagen inherited to Rhyniognatha babies unless their wild parents were previously enhanced with it. Moreover, imprinted stats do not get carried over, even at 100% inheritance, so it is safe to use cloned dinos to get Rhyniognatha babies.

Utility
Rhyniognatha has the ability to utilize a material called Resin, which is periodically generated when leaving
Sap inside its inventory in a 1-to-1 exchange. It acts as a tool both for setting Resin Armor with enough Resin, or as an ammo for Resin Attack on its tail.
- Bomb projectiles explode a puddle of Resin, gradually sticking affected creatures and enemies in a spot for a short duration. This resin variant applies the most resin debuff than the other 2 variants below.
- Needle fires a rapid shot of Resin, acting more of that similar to an Assault Rifle. Damage caps off at 75 damage per needle.
- Rocket fires a slower shot of Needle made of Resin, but produces more damage, more than enough to inflict resin debuff. Holding down the right mouse button will allow you to fire it as a homing projectile.
Resin armor gives it more durability, allowing it to take more damage against incoming damages, but limits itself to the ground (or sea), and prevents it from firing projectiles or carrying anything. It also drains resin when it is active.
Roles
- Creature and Furniture Carrier: It can carry huge creatures up to rexes. It also has the ability to carry certain single furniture like a
Vault and places them as an
Exo-Mek would.
- Heli-Creature: With its ability to fire a projectile using its tail while hovering in the air, Rhyniognatha can easily attack from afar and above.
- It is also possible to wield weapons while riding a Rhyniognatha whether being the driver or passenger. With weapons like a tek bow, minigun, shotgun, tek pistol, or tek grenade launchers, paired with its high agility and mobility, a Rhyniognatha can act as a living helicopter that is armed to the teeth.
- Scarer: It can utilize a roar that scares most creatures, including
Yutyrannus (Not working on
Nameless).
- Titan Killer: With high mobility, melee, armor abilities, and health, a small group of players on Rhyniognathas armed with either compound or tek bows is able to take down any of the three titans in minutes provided they are constantly moving to dodge their devastating attacks.
Carriable Creatures
The Rhyniognatha can carry all creatures that a Quetzal can carry as well as a number of heavier creatures.
The following creatures can exclusively be carried by the Rhyniognatha :
Basilisk
Diplodocus
Gallimimus
Kaprosuchus
Karkinos
Magmasaur
Megalosaurus
Paraceratherium
Procoptodon
Reaper
Rex
Rock Drake
Spino
Yutyrannus
- Note that it cannot carry Paraceratherium with Platform Saddle.
The Rhyniognatha cannot carry aquatic or flying creatures, Alpha Creatures, Bosses, Titans and certain Event Creatures. Besides those the following creatures cannot be carried by Rhyniognatha:
Carcharodontosaurus
Defense Unit
DodoRex
Exo-Mek
Giganotosaurus
Managarmr
Mek
Rock Elemental
Super Turkey
Tek Stryder
Titanosaur

Notes/Trivia
- With the release of Community Crunch 355, it was revealed that the Rhyniognatha would be the final piece of content added to the original Ark: Survival Evolved before focus is shifted fully to Ark: Survival Ascended.
- The original dossier was made in 2021 by Zichfried[3].
- Rhyniognatha is the second entity to have a key tutorial text at the bottom left, the first being
Exo-Mek while under its RTS mode.
- Rhyniognatha combines a lot of features from multiple creatures:
- The way to tame and give birth is similar to
Reaper, except its targeted at a creature and will need to be fed random items to increase its potential max level.
- Its ability to carry creatures is seen in most fliers, but it can also carry Vaults like
Exo-Mek does while flying.
- It can carry some heavy creature like
Quetzal, but is able to carry even more, including some of the climbing creatures.
- Its ability to retain its helicopter-esque hovering is similar to
Desmodus,
Tapejara, and
Tropeognathus.
- Its scare roar ability is similar to
Sinomacrops, but its roar can scare off much larger creatures.
- The way to tame and give birth is similar to
- Probably because of its utility, the growth rate is comparable to Giganotosaurus, but since it has 30% maturation upon birth, it's total maturation time actually comparable to Yutyrannus.
