I have just recently tamed one of these thing and they are ridiculous! Step one: if you are a high level get a long neck with tranq darts if you are a low level get a crossbow or a normal bow and get about fifteen arrows for taming. If you know where a snow area is than go there, but if you don’t than listen there is a peninsula that has a spino spawn as you get to a higher level once you are in the center of the peninsula (not in the water at the forest line) you will head up and go LEFT but do NOT go inland on the rivers just follow the coastline I recommend getting a few raptors or a baryonix because you might need to defend your unconscious argy once you are in a sighting distance from the snow you might see an argy or two flying around. But whatever you do there is one danger to this taming scorpions and hiuenas I recommend not attacking those and from a distance shoot at the argy and lure it away from the hiuenas and the scorpions and then nock it out. Me and my friend used two cooked prime meat to tame this however it was a level one it was still awesome. ATTENTION PLEASE READ AFTER TAME head back to the peninsula but before you go to fare down the coastline there will be a massive tree with two stone arches with and explorers note if you have a saddle ride your argy onto the not and my lvl one got eight levels and we beefed him up our character even got an entire level even though we are like level eighty if you liked this tip please tap on the arrow pointing towards the sky

So to make a argy trap that I think is best is make 4 dino gates made of stone and not behemoth then make 2 reinforced doors then once u do that then place the dino gates 1 foot away from eachother then place the 2 reinforced doors at the end and run through there with argy run through the side and close the back door boom u got a argy

All I typically do to tame it is that I just sit on a good level stego with hardened plates and shoot it with a longneck and some tranq darts.

Worked on a 135 arge with primitive longneck

Just took a few extra darts as I missed a few times as it was flying away

Then just go collect some prime meat and feed it narcotics when needed.

Argentavis’s are carnivores so make sure you have a good amount of meat on hand. Prime meat is preferred. Make sure you have a tape jars tame so you can mount on the wall and then shoot the argentavis. Make sure the argentavis isn’t around any bigger carnivores like carnotaurs or rex’s. Once tamed, take your creature home and make the saddle so taming is so much easier as you now have a creature to pick up Baryonixs and smaller creatures so you can make a taming pen

Use stone dino gate and 3 or more then 1 gate and 3 stone fence support one side the gate and the other the fence supports then u and your pt can walk or fly through the fence supports and the Rg can not then will the Rg is ago on the pt u can walk arund and close the gate and trap him or her for an easy tame
