Argentavis can now pick Anky up. Makes for a great metal, obisidian and crystal gathering pair since argy reduces weight by ½.
Ankylosaurus
The Ankylosaurus is a heavily armored herbivore specializing in harvesting metal and other mineral resources. Its durable body and crushing tail make it a sturdy, if slow, defensive mount.

Player-written tips for taming, using, and fighting the Ankylosaurus in ARK: Survival Ascended & Evolved.
Find a low livel use boomerang. And throw
If you want metal at an early stage this Dino is the way to go
If on abberation i suggest pumping weight for starter anky.
they good at mining metal but you'll mostly encubered them when on ride after hit around 6 metal rock try pump on weight level
Can be picked up by argentavis now which is immensely helpful
If you wanna build with metal, this is your dude.
There is armor on the body, so tranq at its head; you can do this with just a slingshot ( tamed an ankylo as my #1 priority in ARK)
Just get tranq arrows and run while shooting it it’s that easy I would recommend a bola though if it runs
But if you don’t have tranq arrows bola it and hit it with a club it will take a while but it’s worth it
This is an easy tame because ankylos are very slow so you can slingshot it and make sure to keep running!!
Hey, it took only 17 dilo kibble instead of 40. (Mobile version)
This took 27 traq arrows with a regular crossbow for me, taming a level 96.
Best Dino for havesting anything
Pair it up with a high lvl argent and your good to go.
Can be carried by new TLC argy, making it a quite easy and useful tame
Argentavis can now pick up an Ankylosaurus so that means you can bring it out to a taming pen and tranq
If you use an Anky paired with an Aberation crab holding it you and a buddy can get ridiculous amounts of metal. From what I can tell it is the new fastest way to get metal in my opinion.
Great for harvesting oil in the arctic
If you want to make a lot of ammo fast, you can't beat an anky.
Granted, you need to get your charcoal from a different source, but you'll be swimming in sparkpowder and metal in no time with it.
Well, since ankle is a somewhat slow creature use this to your advantageand, and it always has to do a 180 spin to hit you so when it starts to spin jump backwards (probably should make sure there is nothing behind you though) jump back, hit, jump back, hit. You'll get the idea.
