Not every creature can “eat” the pheromone that the males drop.. like this tip so Dododex can see and add which creatures can eat it and which ones can’t.

I know some that cannot:

Megatherium

Stego

Tek Creatures

Anky

Doeds

Sarco

Baryonyx

Carno

Managarmr

Some that can eat:

Wyverns

Rex

Quetzal

Maewing

Trike

With more testing we could have it set up fully and implemented into DodoDex

For those that don’t know it will eat through the food f the tame you’re using, so have lots of food ready. I used a Bronto with 46.8k food and it was depleting it in 3 mins. Veggie Cakes help keep its HP up too so you can finish the gestation.

Before you tame you need to know that they kill your tame after its been impregnated

TAMING

- Get a TRIKE that you DON’T love

- Bring it to the Swamp

- Kill a MALE Rhyniognatha

- Bring a FEMALE semi-close to your Trike

- GET THE FEMALE BELOW OR EQUAL TO 100 HP

- FEED the Trike the PHEROMONE you got from the MALE

- IT WILL IMPREGNATE THE TRIKE

- YOUR TRIKE WILL REQUEST 5 DIFFERENT FOODS

(YOU DONT HAVE TO FEED IT THE FOODS BUT IT WILL HEAVILY IMPACT THE LEVELS AND STATS)

- Once the timer hits 0:00 Your Trike will go UNCONSCIOUS AND DIE

AND THERES YOUR BABY RHY 🥳 (R.I.P Rex lvl 72)

Taming these things are confusing, but I believe I have figured out how they work.

Step 1 is to kill a wild rhynio (can be any gendrr) to get the pheromones, next it is best to make a trap, the best design i know of is basically a stone dino gate griffin trap, but with behemoth gates. Next you want to find a high level wild female rhynio. Think of the level of the rhynio as the taming effectiveness you will recieve 150 being max. Next you need to lower the rhynio to below 10% hp, you can net them to make this easier. Once it is below 10% hp you need a mount with a high drag weight in order to inherit the best stats, carch/giga have best chances. Feed the creature the phermone and mount it. The rhynio should impregnate it within a few seconds. DO NOT CRYOPOD THE DINO IT IMPREGNATED! YOU WILL LOOSE THE BABY! once your tame is impregregnated it will go through a gestation period and ask for cravings. It is important you furfill as many as possible as they have a major effect on the level the offspring will be and the stats inherited. Once the timer is complete your dino will fall unconscious and die, however you will now have a new perfect tame rhynio!

All of the currently known cravings for host creatures include

Giga eggs

Carchars eggs

Quetzal eggs

Golden hesperornis eggs

All kibbles

Shadow steak saute

Fria curry

Enduro stew

Focal chilli

Lazarus chowder

Veggie cakes

Black pearls

Achatina paste

Gasoline

Element

Rhino horns

Ammonite bile

Bee honey

Battle tartar

Just a quick tip, Now only males will drop pheromones,

DONT KILL THE FEMALES!!!

This is the ultimate way to get this early game. First go to the plateau near south zone one a build a giant stone wall I recommend it be point towards the volcano mountain. The will should be built six foundations by 4 it is expensive but it won’t break. Then use regular stone door frames and do your best to cover up every foundation with a celling. Where you want the rhynio to enter just put two door frames building from top to bottom. This will make the rhynio stay in the trap and not fly out when it tries it’s ranged attacks. Then tame a paracer, you want it with at least 3k health. Put the paracer behind a rock and give it a lot of berries. Now lure a male rhynio using a pt. No specific stats I recommend for the pt as long as a pt can get you to the plateu you should be good. Then using a crossbow aim for the head as it does 1.5x the damage. I recommend the pt to have more than 500 health and for you to ride it in 3rd person so you can avoid getting shot with resin. Once you get the phermone I recommend you place it in your paracer and. Now using chitin armor I recommend you go on tour pt and lure a female rhynio. Then start shooting it in the head with a crossbow. Then check it’s health using a spy glass, back away if you see it trying to do a tail attack as these can kill you very easily. Once you notice the health is dangerously low use a regular primitive bow and aim for the body. This will allow you to get the health lower without killing it. Then go with go behind the trap and force the rhynio out. I recommend you make the trap 6 door ways high that way the four bottom door ways allow the rhynio to escape. Note if you make it six high but you block of the top 2 door ways this will allow the rhynio to get in if it is chasing you but due to the rhynios flight pattern and dino ai it can only leave if you bait it again with your pt. Once you bait it out take it near your paracer, jump of your pt, ride the paracer, go in it’s inventory and feed it the pheromone. I highly recommend using a saddle as rhynios do a lot of damage and saddles can negate a lot of it. I recommend you take your paracer to the rock formation on that same island that points towards red ob as it is quite safe and spacious. The rhynio will attack quite a few times before it impregnates your dino. Note daedons could be useful as they can keep your dino alive for extra time. If you are on a server the 1.0 character and tamed dino healing will be enough to keep your dino alive during the pregnancy, but it is guaranteed that no matter how much health or how good your creature saddle is, your dino will die when the rhynio enters the server world. You don’t have to feed it cravings but if you want to feed the maximum cravings possible in your control I recommend fishing as you can get absorbent substrate and hunt trilobites as they can give black pearls and oil for gasoline. The rhynio will typically come out a similar color to the female rhynio you used, but not the same color. The female rhynio I used was black and blur with a bit of beige. My rhynio came out black and white and a bit beige. The rhynio also can bebe crypoded and thrown out on single player on mobile without a cryofridge. You can throw the rhynio out of it’s cryo as many times as you need to this can reset what it needs for imprinting. It usually only needs two imprints, usually the best request is cuddle as it doesn’t seem to follow you even after the whistle. So that makes going on a walk impossible. Not only that but when they grow up they don’t follow you when you whistle follow. Note that they have colored eyes when domesticated and when wild they have black eyes. You can get multiple different colors on these. They also are inmune to their own resin attacks so if a wild one hits you with it’s attack it won’t do anything just like wyverns when they shoot their same species wyvern. I hope this helped you out and if you are low level check out note run videos with note runs even if you ate high level you can easily hit level 90 and on the southern part of the map there is a lot of notes so don’t worry if you need to use em and obsidian spawns a lot in caves so if you need obsidian go to a cave they somehow don’t have as many creatures as they used to. Note this strategy is a beginner strategy if you are more advanced in the game other strategies might suit you better, and this strategy only works on mobile.

PAY ATTENTION PLEASE!!!

GET A DINO WITH ENOUGH HEALTH TO IMPREGNATE!!!

From all the info I got, this bug is real annoying to tame but I still believe I can do it

My Technique :

I got the Pheromone from the Male

I tranqed the female ( it sleeps a lot )

Tamed a bronto

Made sure it got food but it didn’t have enough health (2.5k)

Then Rhynio woke up, I fed the bronto the pheromone

The TRICK you don’t see is the Rhynio has to TAIL ATTACK 10-12 times before it impregnates, it doesn’t just hit once and leave and that drains your Dino’s health

So moral lesson, get a healthy host

Use a direwolf on ark ascended to easily tell when it is below 10% health
