Might be a bit hard to tame one if you're low level like me, but like all the other comments said, It's absolutely worth it. I had a bit of luck and ran into a level 35 argy, after being chased for a bit and then chasing it a bit I tamed it with raw prime meat and got it to level 40+. Equipped even with a primitive saddle, this bird can tear through anything that's level 30 or below. Terror birds? Sabertooth? Lift up and kill. Need prime meat? Slaughter some paracertheriums or diplodocus. Want a Rex bone helmet? Fly straight into its back and start clawing! So far the only things I have encountered with argy and haven't managed to kill are Titanosaurs(for obvious reasons) and Allosaur packs (I am positive that the argy can handle them with a few easy prey nearby, but I wouldn't take that chance.). No Rex or Spino or Bronto can stand up to it as long as there are other prey nearby for it to regenerate its health. So go ahead and tame one as soon as u can!
