Riding a frog doesn’t aggro them!

you can find them the most near the redwoods and the swamp on like that little beach at least on the map the island you can find it on that beach but other than that, I don’t know where to find any sometimes you can find them in like the actual swamp, but it’s very hard to do this so so I just look on that little beach

hope this helped

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

Be carefulful around the swomps cuz rhynignathas ARE NOT RARE AT ALL. I got jumped by 6 once on my spinos and ran and then by 7 ish when I was on my giga(at the same time)

Once you tame one it gets way easier to do literally everything

For best tame ing and making SURE NOT TO DIE you can make a trap by using 4 stone dinosaur gateway trap one and do the normal process don’t forget to get dinos on passive and have high health dinos like paracetherium you can use trike to but high level

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

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!

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!!!!

I recommend using a pump action shotgun to take this thing down. I tried to tame one once and it killed my pt named Greenbean (see the pteranodon entry for his story) but I actually managed to get one. It was only level 7 because I couldn’t give the Bronto host the element it was craving.

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!

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.

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

Wild dinos ignore you while you are on it unless you attack them except if the dino is an allo, spino, rex, alpha rex, yuty, carcharo, giga, rhynio, or insect buffed megatherium which will attack on sight.

Trap the rhyniognatha after it impregnates your Dino that way you can reuse it later for more rhyniognatha taming

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🤣

I impregnated rhymognatha of host bronto lvl 226 and it impregnated by rhymognatha lvl 140 but after rhymognatha born it's level is only 47 an it show that she follows me but she can't walk that's why I can't completed 2 imprinting that's is walk with me so guys have you any solutions
