You don't need to incubate at random dangerous places. Just place your host at your base and then aggro rhyniognatha with high level and mov speed sometime it will distracted but you have to agree again until your reach your base and make sure other dinos are passive and then proceed further and this way you can focus on cravings more efficienctly

I suggest you find a nice beefy dino If you don't already have one, make sure it's carnivourus so you can deal damage to the Rhynio, use that dino to kill a low lvl Rhynio, because if it's a high level female it would save you time searching for one, once you go out and kill one lower the Rhynio to 10% this part is very tedious you can easily kill the Rhynio with a good dino, once you get it low enough, feed your dino the pheromones and when it gives your dino a quick sting and your dino has a buff on it showing the amount of time until a baby, feed it's cravings or else you'll have a extremely low level one, make sure to immediately feed the baby and imprint on it the second it comes out, good luck!

Carchas can incubate as well - have one player hit the Female Rhynio until she's below 10% health. During this, you ride the Carcha and feed it the Male Rhynio pheromone. When the Female is below 10% health it will automatically disengage from your friend (I assume if close enough) and start hitting the sacrifice tame. It'll have a really noticeable red cloud around the tame when the Female was successful, and then she'll fly off.

The incubation time will begin. You want a dino with a large health pool because it will start to go down as the incubation continues, and when the baby Rhynio hatches it will kill that tame. If the sacrifice tame dies before incubation is complete or if you cryo it, the incubation will terminate and progress will be lost.

I suggest having a 'box' to keep the tame sacrifice in while it incubates, because it takes some time and you want to keep the sacrifice tame safe and alive. I just did stone fence supports and then large stone walls to surround the tame. You can then cryo the baby Rhynio AFTER it hatches (explodes) from the sacrifice tame, bring it back to base, and raise it in safety.

Good luck!

Ok friends let’s began well it’s a passive tames, it is creepy and fights EVERYthing , and you must kill one and then feed its faramone too a tame of yours then when you find a other one it will put a egg in your tame

And your tame will have cravings fulfill its craving for a better rhynothia and it will rip out of your tame killing your tame 😖 and it is discouraging, these bad boys can blast out cement and can pick up diplo’s .

To tame the rhynio you will need to find a male (drops rhynio pheromone) and kill it. Part two: The stronger the creature the better the rhynio baby, I recommend a Carchar but if Carchars are limited mutated brontos work really well. Part three: Find a female rhynio and trap it, after trapping it get the rhynio down to low health, throw out the Dino that you’re feeding the pheromones and wait for the rhynio to impregnate your Dino. Make sure that your Dino is on passive or it might end your plans to tame a rhynio. :)

Bruh I heard about them dreamed of taming one had everything I needed to tame one and I searched for hours for one (or more like two) and couldn't find one then found out that they are NOT ON SWITCH YET! I play on switch so I was literally devastated. If you play switch do NOT go after one. YOU WILL NOT FIND ONE!!!

1.Get pheromone from dead rhyniogantha

2. Find suitable female

3. Net and bring to about 8% of health

4. As soon as it gets free feed sacrifice tame pheromone

5. She will impregnate and de agro and fly away.

6. Use a 5 behe trap to repeat with as many sacrafice tames as you want.

For some reason my rhynignatha decided to stop flying mid flight high up, and well of course lost al his hp and died. I think it was a bug but now I need to get another one. I got my first one cuz the female was stuck in a rock. I hope this tim helped you be more careful with your rhynignatha.
