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

This isnt really a Taming Tip tho it is a Good tip. If your trying to hatch a Argy egg or just any egg But dont have a Ac Unit then go to the snow area(This Only works if there is a snow area Like on the Island) And set up a little campsite there(Kinda like a small house or base) and fill it with campfires. Light all the campfires and the Egg wont be to hot. This might not be for everyone but it worked for me

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.

Argie traps:
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.

Best way... build a cage with a Dino gate and lure it in and you can tranq and tame it in peace
