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

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)

Traumatic experience tried to outrun it on pt🫩

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

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!!!

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!

These bugs make taming other dinos a LOT easier, and grinding more bearable. Now you don't NEED a high level one.i got a lvl 35 weeks ago, now lvl 95, doing wonders for metal gathering because of their high weight, though if you're far from a metal source, i'd recommend argys, since rhynios, when carrying dinos move horrendously slow.

Well, it's simple (not really, but still pretty simple for their uitility that they give you) first, find a male (level of the male doesnt really matter, but females do) after killing one check your dinos inventory, or the rhyniognathas dead body inventory. If you cant open the rhyniognathas dead body, then the pheromone should be in your dino's inventory.

Select a tamed dinosaur, preferably a brontosaurus, or carcharodontosaurus, or gigas. Though rexes, paracers and other animals could work, but not all of them. 𝙎𝙀𝘼𝙍𝘾𝙃 𝘼𝙍𝙆 𝘿𝙄𝙉𝙊 𝘿𝙍𝘼𝙂 𝙒𝙀𝙄𝙂𝙃𝙏𝙎 Drag weight matters very much here, because it ensures full stat transfer from the host dino to the rhyniognatha, 900+ drag weight is the max limit for stat transfer, making carchas, gigas and brontos the best option, if you want a rhyniognatha specifically for resource gathering, sacrifice a bronto, if you want damage, sacrifice a giga/carcha. Brontos have high weight, carcha/giga has high damage, if you want one SPECIFICALLY to just be a speedy fighter jet that doesn't fight, sacrifice a bronto with high speed, if you even level it up on brontos.

Second, find a female, high levels are great, but if you're desperate, low levels are great too. If you've located one DO NOT FIGHT IT YET! If you have a cryopod, use it to store the sacrifice and uncryo it near the rhyniognatha, if you don't have one then you'll have to go primitive and ride the sacrifice, or make it follow you near the rhyniognatha, feed your sacrifice the pheromone you got from the male, and quickly get aggro from the rhyniognatha. Attack it, lead it near your sacrifice using your dinos, or weapons till it reaches below 10% of their hp. The female rhyniognatha should shoot out some orange glowing blob at your sacrifice, your sacrifice is now bearing a rhyniognatha. (It should be glowing orange) from there, prepare the foods it will request. Search the things that it might ask for in its "Still stuck inside your sacrifice" Phase, just incase prepare element, they can request it.
