I lost my 197 Argentavyy cus of these freak, bro stun my argy mid air.. R.I.P Genta🥀

“Wahoo! My genius plan to kill a male worked! Now I just have to search my 25 carnivores for the pheromone… AAAAAAAAAAAAAARRRGGGHHHH!!!!!!!!!!!!!”

Tired of wasting that resin on your potoato aim? That bothersome compy keeps dodging your shots? Try Rhynios Sniper mode! Simply equip a spyglass and notice your reticle center on your target. Guaranteed hit. Happy hunting.

IDK how I'm soposed to manage to get a giga egg even though I have yet to come to see one

I hate these motherfuc***s with all my heart.

I tamed a level 150 ptero and later increased its level upto 256 she was perfect perfect. I was traveling all around map within few seconds but when I sit to rest and gain stamina, a group of these assh*les attack me and kill my Potterz, miss you buddy 🥲.

Riding a frog doesn’t aggro them!

For the guy who said it is scary to encounter on a pt, it is also scary on a max level argy. 😟

THEY ARE NOT RARE AS THE DODODEX SHOWS!!!! they are everywhere on the swamps near redwoods. THEY SPAWN IN GROUPS! THEY AGGRO FROM FAR AWAY! THEY ARE FAST!!! THEIR ATTACKS CAN DISMOUNT YOU!!! THEY ARE ABOMINATION INCARNATE!!!!

Don’t try to out run on pt most likely leads to death

Run thats all i have to say if you are not prepared RUN THE OTHER WAY, RUN HOME, RUN OUT OF THE SWAMP, RUN OUT OF THE REDWOODS, JUST GET AWAY FROM THOSE MONSTERS THEY TOOK EVERYTHING FROM ME

Unfortunately, to the guy who asked if the pheromone can spoil… Yes, it does spoil. It takes a whole day thankfully. Just make sure you’re prepared to take on two rhyniognatha in a day and you should be fine. 👍

As of November 2025, their ai on mobile ark still sucks.

Dont bring it to the wyvern trench. Lightning wyverns can knock it out and it will never wake up in time. Use non-valuable tames if you can.

- RIP Midnight

rare is not it for ark mobile. these things spawn in a freakinf PACK

Best confronted with Megatherium.

The Paraceratheriums can eat the pheromones too which is extremely helpful because they are easy to tame, practically useless AND they live in the same area as the Rhyniognatha!

The easiest Dino to use if you just want to tame a rhyniognatha NOT FOR AMAZING STATS OR ANYTHING, is a spino because they have way to high hp and the damage is low enough that you can easily lower the ho of the mother without having to worry about killing them

Hey my fault for my other comment I ment to say. Use a good stam and melee argy fly super close to it and fight.

This thing is jack of all trades master of all. you want to farm its got you covered, you need to go in the ocean this thing can swim pretty, fast you need to murder everything in the tristate area its on it. this thing will do it all.

They are literally the worst on ark mobile ultimate edition.

Not rare, incredibly aggressive, and like to wander. I tamed myself a lvl 60 thyla and it got killed on the way home by these guys as I was running away. Luckily, I got it back by cheating slightly(back up save… it’s literally a savior for crappy situations). I’m planning on taming a spino (my favorite tame ever) so that I can travel in the swamps again but with the ability to destroy these idiot supersized mosquitoes. Good luck you guys, stay away from the swamp if you can help it🤣
