Ay yall j learned this the hard way, but the drag weight of the host creature matters!! I had a 135 female impregnate my trike, and even though I gave it all the cravings it came out a 68, but I did a 125 female with. Bronto and it came out ~lvl 150. Make sure your don’t make the same mistake!!

If your on the lost island you can possibly find one in swamp areas. If your on the island probably check redwoods or swamps. If your taming one kill a male since the females don’t drop pheromones, find a female, use a harpoon gun ( put the net ammo in ) use something to get the female low. Get a dinosaur ( I recommend giga or carcha to get higher chance of it inheriting the stats ) feed it to your dinosaur . And let the female to impregnate your dinosaur. And there you have it a rhyniognatha. Just don’t cryo your Dino or you lose the rhy.

If you guys are wondering how a rhyinoganthana baby level is determined it depends on the level of your dino (host) and the female rhyinoganthana that impregnates your creature also cravings really matter a lot the formula of cravings it that the total cravings you feed the creature divided by the total cravings you could feed the creature basically around 4-9 depends on server boosts or cheats.

If your trying to tame one don’t put the creature in a capsule because it will cancel the requests of the rhynio

This is not passive taming

You have to get it to 10 percent

And let it get your dino pregnant then a baby explodes out of your dino killing it

NOT PASSIVE TAMING

Quais donos servem pra gestação dela?

There’s a bug on the server I’m playing PVE, the Dino you used the Pheromona on dies on the last 1 second literally, I lose 3 Dino’s trying that; if you have the same issue use an Owl to heal the Dino 6 seconds before the incubation is done and it’s gonna work I tried it today and worked!

On the Switch you're currently not able to feed sacrificial dino's the cravings the baby wants. Tried everything on 2 different impregnated dino's and nothing works. Don't waste your time or tames till it's fixed :(

On ark mobile ultimate. Upon continues taming trying to get a high level. I have come up to a conclusion that levels and cravings matter. I used a lvl224 bronto around 30k health then impregnate it with a lvl130 rhynio. My baby rhynio(evil orange) comes out to be LEVEL 176.

1st craving : ammonite bile

2nd craving : absorbent substrate (i think,can't remember the name that well)

3rd craving : golden hesperornis egg

4th craving : extraordinary kibble

5th craving : another absorbent substrate

Hope this helps.

What I did was I first knocked the female out and slowly chipped away at her health, and once she woke up she impregnated my Bronto.

ok, do you wonder how to get the perfect rhyino? well it takes stats from both the host and the wild female, to draw more stats give it cravings. it will eat all the island rockwell recipes, all kibbles, black pearls, anthica paste, element, quetz, carcar, giga, and golden eggs. and something else, and another is drag weight. the higher the better. what happens is it draws more stats from the host therefore it will be higher level brontos have one of the highest drag weight (1050), so mutated brontos are good. it only will take points so bronto or giga are no different on how strong the baby is, so lets say you have 50 health points. and you give all 5 cravings with bronto. the baby will probably have 50 health. other good drag weight creatures are gigas, carchas, and megachalons. (950)

(Don’t try this) me and my tek raptor tekey were rubbish through the swamp because one just killed my pelagornis and I got jumped my two of them both level 12 and somehow my tek raptor level 77 killed them both and then I died💀

Finally was able to get 1 for myself by breeding it with bronto in ark ultimate mobile edition today

it got insane good stats

it's good

I'm happy

but yea waited for more than 2 hours for baby to mature

Guys a huge tip to tame this creature is to finish of a low level male get the pheromone tame a rex or stronger for best effectiveness on the rhyinoganthana baby’s stats pacers and brontos are fine but if you are looking for stronger rhyinoganthana use a rex or carcha or giga then find a really high level female ( low level is fine too depends on how strong you want your rhyinoganthana to be) Finally dismount your creature while the rhyinoganthana is attracted to it shoot the rhyino to less than 10% hp tip just divide the health by 10 anyways, then feed your dino the pheromone wait for it to get impregnented make sure to feed it all the cravings it wants if you want a really good rhyinoganthana using this tip I got many 120+ lvl rhyinoganthana and one of them is so strong it does like 2k damage per hit so yeah guys good luck. Also rhyinoganthana can be deadly so use a really high level argy or a good shot gun

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.

Steps to Tame

1. Kill male to get pheromone.

2. Use a large Dino… Rex, Giga, Spino, etc.. base stats that I know of count for a better baby bug. Put this Dino on Passive.

3. Find a Female.

4. Set up a trap using about 6-7 stone Behemoth structure close together, put gates on the ends. I use Tek gate much easier. Leave small gaps to go in and out of.

5. Lure female into gate and shoot with net gun. .

6. Grab your Dino that is on passive and walk it in and close and lock the gates. Try to use a Dino that has decent health.

7. Use Magnifying glass and look at health. You need to get it down to 10% remaining. Use net gun to check health and take your time, have a sleeping bag near by in case you die.

8. Feed your Dino the pheromone, and watch the tail of the bug glow, after it should go to your Dino and impregnate it.

9. Thats it, for breeding it will need a lot of food and some way to heal your Dino like a snow owl, or just force feed it food. Your Dino will want a lot of different things, like kibble, soups, I heard gasoline too lol.

Cheers and Good Luck.

On mobile it chooses a new craving directly after you feed a craving to your dino similar to imprinting, but you wont see it until the cravings cooldown is up.

This means if you are save scumming to get better cravings you should do it before you feed a craving to your dino, then after you feed it wont tell you the next craving so you need to wait until the cooldown timer is up, then if you get a bad craving you need to download and wait out the cravings timer again.

this also applies to the first craving you need to save before your dino dies instead of before the first craving timer ends if you want to roll a new first craving

If you save seconds before the cravings timer is up, you will get the same craving every time you download your save.

Best thing to do is to have a harpoon with net attachments,net it, take it down to 10 percent health, un cryo a decent sized dino n fees it the pheromone,when its out the net it will lay eggs instantly,.... Also don't cryo the dino after it will stop the incubation completely

Make sure you have every little ridiculous thing it could possibly ask for. My bronto was a level 280 and the Rhynio was a level 140,but I got a level 61 baby because I couldn't satisfy the second craving.

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.
