For your first, the Northeast Shores, there are a few that spawn there but beware of Rexes, Allos, Carnos and Raptors, also the beach head along the northwest coast, just short of the snow biome. Other than that, they spawn on mountain tops - but that's more dangerous area.
Best advice: Tame a pteranodon first. Kite the prospective Argie to a safe location and into a trap. Tranq with a crossbow (bow can kill) and tame with prime meat, mutton or kibble.
1. Trapper Raft. Must have ceiling and two doors. Pros- can be sailed close to location and tame on water away from potential threats. Cons - initial investment of time + material.
2. Dino Gate trap.
4 stone gates placed sequentially half a foundation apart with doors on first and last. Lure into the trap on ptera and close gate behind you, dismount, close 2nd gate. Cons - exposed to smaller predators during taming. Use spiked wall perimeter.
Use stone, can destroy wood/thatch.
You can insta tame it by making it attack you and it will harvest a body then knock it out when it has the health increase stat (green thing around its head)then once it is knocked out I will tame automatically, HELP THE BOBS
#Toriel. There is a recall button in Mobile, if toriel isnt dead you can teleport her back to your side in about 10 minutes. I know Because I've had to do that with my Eerie Argie several times. She will lose everything in her inventory though. Howevwr you will have toriel back. Hope this helps, Happy Hunting!
There is a working glitch right now that allows you to (almost) instant tame these things. First, trap the Argy in a simple trap you can walk out of but the Argy cant fly out of. Second, put all of your items in a box next to a sleeping bag next to the trap and then commit die. Respawn at your bag, shoot the argy with lots of tranqs and use dododex to make sure you dont knock it out. Third, take your dead body and drag it within reach of the Argy, once the Argy consumes it its head will glow green, now knock the Argy out the rest of the way and its food bar will be drained heavily.
This allows for a near instant tame and works best on the lower levels. Using this method on an Argy makes it a faster name than a Pteranadon.
I used this on Thanksgiving day 2019.
