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

How to easily tame one for early access to end-game transportation:

Things needed: spyglass, tamed trike, trike saddle, sword, simple pistol, at least 50 simple bullets

Recommended player level: level 35

1. Tame any trike then after its tamed ride it and destroy trees or kill creatures until it gains enough exp that you can pump several to a dozen levels in health into it.

2. Go to the swamp and find a rhynio, then target it with the spyglass to check if it's male or female and what level it is, obviously don't get close enough that it starts chasing you.

3. Assuming the rhynio is low level and male then you are set to kill it, but if it is too high of a level to kill or female then find a new one. Many tips will say just to kill it but never actually explain how to before it can kill you, so here's an actual good way to kill it:

4. Equip the sword and simple pistol in your hotbar, mount your trike then find the rhynio, aggro the rhynio using the pistol and magdump it until the rhynio gets close enough and starts attacking your trike, then equip your sword and start swinging at its face as much as you can until it dies while your trike tanks the damage. If it starts shooting resin at you then switch to your pistol and start shooting at it (This requires quick and precise aim as the rhynio can move from spots quickly while it is shooting resin). After it dies open its inventory and take its rhyniognatha pheromone.

5. After you take the pheromone, you can wait for your trike to heal while watching the spoil timer of the rhynio pheromone then find a low level female rhynio, feed the pheromone to the trike if it hasnt spoiled yet, then do the same attack process described in step 4 but don't damage it so much that it dies, you can then wait for the rhynio to impregnate your trike then it will fly away.

6. You can choose to satisfy the trike's cravings or not, but since this is a beginners' tip it wouldn't matter if you did or not. Put a lot of berries in the trike's inventory, then you can just wait until the gestation timer finishes and your trike dies.

7. After your trike dies and your juvenile level 1 rhynio pops out and lands somewhere near where your trike was, put enough raw meat in it's inventory for it to last until it becomes an adult and you can imprint it if you want the damage and resistance buffs.

8. You now have a tamed rhynio, end of tip.

9. Just kidding, while you wait for your rhynio to mature you can grind explorer notes until you get to level 91, (takes around 20 on singleplayer) and since the rhynio's maturity timer takes so long you might even be able to craft the saddle before it reaches adulthood.

10. When your rhynio reaches adulthood you now have a flyer that is faster than a quetzal, has more weight than a quetzal, can pick up almost all land creatures in the game, and cannot be attacked by most aggressive creatures unless you attack them first.

Note that since you have a level 1 rhynio you should avoid fighting other rhynios, as it can easily be killed if 2 or more rhynios attack you at once

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)

To the guy that said if the cravings are needed or if they improve the rhynio level: Cravings heavily depend their level, you could have two extremely high level parents (check other tips for taking these suckers if your confused on the term “parents”) but only get a level 30-40 rhynio. Hope this helps!

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

DO NOT CRYO AFTER IMPREGNATION, When you do it the dino will not be pregnant,

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

DONT KILL THE FEMALES!!!

the quality of the baby rhynio depends on few things, the wild rhynio level (150 for the best result), the host drag weight must be above 900 (bronto,carcha,gigan on the island), the host's level and stats (stats is important because the host is also a parent so its like normal breeding), and the cravings fulfillment. also imprint the baby for the best stats, ive tried this multiple times with my bred brontos and i always get 240+ baby rhynio

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!
