One thing besides being amazing at metal and flint collection, is to be sure and get the oil nodes too. High collection rate for a land animal.
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.

What ARK players use the Ankylosaurus for, and how to get the most out of it in ARK: Survival Ascended & Evolved.
The ankylosaurs is a massive epic pickaxe of mass destruction that if used correctly can get you so much flint and metal that you won't know what to do with it , dilo's are easy to tame and so an easy kibble for a epic beast .
Problems with metal? Not anymore! Have a tribemate carry you on your Quetzalcoatlus and get all the metal you need! Just make sure you are well prepared for an ambush.
This is a metal machine so tame it.
Only level this guy’s weight and melee dmg.
Remember if you ankylosaur has high melee damage,it will not get more metal once you put certain point in melee damage
Dunkys are better but theese can go on land dunkys still better got 1k obsidian in 1 bite
You can teleport you dinos in ark mobile so I suggest to do that after you put it in a safe area (tp to bass)
You don’t need a magmasaurus to harvest metal! Just these things!
Get and argie and one of theese dudes and your set for metal
Excellent for gathering Metal and Flint.
If short on rare flowers go to a bunch of bushes and spam alt fire for a decent amount of stacks.
Hating him is what you should be doing if you’re building something his the bast to halp
At around level 50 it is a war machine against dinos, just make sure it has atleast 3.5k health and it can kill an alpha raptor, even if you die 10 times in the process. This was not fun but was amazed when it won the battle
The Anky can smash a boulder with one or two whacks with its bony tail.
The doedicurus does a better job at harvesting obsidian, but I play the mobile so I don’t know about the console or the pc. But I have harvested between twenty and thirty obsidian from one Rock, where as the ankylo only gave me ten to twenty.
pair it with an argentavis to mine metal, crystal and obsidian.
Let the eagle carry stone crystal and ankylosaurus the metal. They are perfect buddies for each other.
This has to be one of the best harvesting Dino’s every due to the fact that it gathers metal, flint and obsidian at high rates and from my experience in gathers the more narco berries per bush then a stego or bronto the only down side is it’s quite slow
Do they do anything on wander?
Best metal collecter. Awesome for metal structures and tools. Get an argy, bring the anky with, get metal and other mats, put some on argy, put metal on anky. Get home with your loot.
