I was chasing after an otter in the swamps west of the Redwoods, then started searching the trees on my Argy and wound up face-to-face with a Rhynio. It scared the absolute sh*t out of me, these are by far one of, if not the scariest creature in the game because they stay hidden and laying in wait in the trees to ambush you. Of course I flew off and it started chasing us, but thankfully I read another tip on here that said if you fly under a Paracer, it will lose the chase! It worked and me and Rufio are still alive to tell the tale. Flyer beware.

I found a swamp that was a ryagnatha hot spot in astraeos

Once these mfers agro to you there's no going back you can either fight or find the closest Dino and just get his agro on it rhynios agro on pretty much everything so by any means don't panic just kill it or get it's agro on another dino

Don’t try to outrun on a pteranodon! You will die very VERY fast!

They spawn on the island and lost island I wish they spawn on fyordor

It’s even scary on a brontosaurus vs a level 1.

Y’all…. They can swim. And that scares me.

Big tip for mobile if getting assaulted by this pest. TAME A HIGH LEVEL THERI NOW. And bada bing bada boom, no more pest problems. Stay near the beaches until you spot a nice level Theri. Level melee to about 400-500%, Then health to about 5K-6K, rest is up to you. It will keep you safe from these things. I found a level 115 Theri and its now level 200, I hunt these fools now.

Be very careful,for they are faster than pteranodons and will kill it and you.

I was killing some dimorphs with my pt and I see a level !!!!!130!!!!!! Appear out of the tree right Infront of me absolutely terrified me I was able to kill it tho but it was a female so rip my chances for a high level rhyno

Thier resin shot will lock up you flying dinos like a Bola in the sky and you will be kicked off to your death....Bring Parachutes!

Don't worry just be on the back of your average level 75 sarco and just one shot it(or maybe an high melee bary) just don't be scared if u have single player settings and I got scared then just...was like what when my sarco named sarko oneshotted it

DO NOT MESS WITH THESE GUYS. I was going on a killing spree with my 160 argy until one of these guys showed up they go for the rider not the mount RIP rocky

nah i was just trying to go to north to get argies (i got them eventually so im not that mad) and i flew over swamp. BIG mistake. two spawned killed my best pt and me and i had to run back with no gear to get my old gear, i did get it so its ok!! but i had no more pt saddles and had to go to north on a pela. took WAY too long. definitely avoid swamp on ultimate mobile edition, take different way to redwoods!! (please.. dont loose ur pts or argies)

I was flying on my pt once, unfamiliar that these even existed (I’m used to old Ark mobile) and it killed my damn pt, I was left stranded with some metal tools and was attacked by raptors, boas, dilos, bugs, and compies. All which I somehow survived as I watched in horror as “Your Pteranodon Icy -lvl 32 was killed by lvl 3 - Rhyniognatha”. I later once I had spent 2 hours trying to find Silicon for spino saddle suited up my 250 melee Spino and encountered an alpha carno which we killed. I felt overly confident and decided swamp was next to be conquered and so we went to swamp and 3 Rhyniognatha’s attacked my Spino and I. I underestimated their power and my Spino and I both met our fate even after killing the first 2. The 3rd one was smart but annoying because it hovered in the air shooting balls of fire and shards at us which soon ended my poor spino “Venom”. You will be missed venom, you were a good girl, best spino I’ve tamed in this run. -MistyRex

I was flying on top of the redwoods swamp and then on agro to me and it kill me , my argy, and I lost all my inventory, that included a lvl105 megatherium(pest control) that was in a cryopod, and two more empty cryopods.They also be in packs of two to three so be ware. R.I.P (pest control). Sincerely from: Anthony the Dino tamer

These things are starting to spawn in non swamp areas. I believe they are supposed to spawn in the swamp areas around the redwoods but it seems they either spawn farther or wander because I’ve been seeing these a lot in areas that should be peaceful. By the way these things are not rare and normally come in packs of 2-3

Idk what the devs were thinking when they made up the taming process on this thing 😭

Lost my 157 pt to these trying to get crystal in redwoods they are pure evil 0/10

Literally a bomber plane nukes you with fireballs there is not escape
