The Ankylosaurus will not attack you in the wild unless you attack first. When battling you can run away quite easily, just be aware, they have high health, so if you plan to kill one make sure you have enough stamina and resources to kill them.

Around mountains and in the southern areas, in general pretty common

Neutral wild, will only attack if provoked, mostly found in easier zones

I find the ankylosaurs is surprisingly a very good swimmer , or well good at floating and swimming it for submerging and going down ,but still better at submerging and going down than most dinos so I guess it could be used for oil but still , down try escape from one in water .

Can sometimes be found on the NW argentavis peninsula on the Island

These are easy 2 encounter on herbivore island if u want to find one fast go 2 herbivore island they easy 2 take down i suggest getting onto a rock the trank them the torpidy goes down suprisenly slow

Ankys are much faster in water than on land and are able to tank most of the megladons right off the edge of the shore

These are surprisingly easy to find on herbivore island I have found multiple so far.

If you spot somone raiding your base with one keep distance use ranged

Won't attack you unless you attack them first Ankylosaurus is basically a slow tanky dino when facing an ankylo ranged weapons are your best chance their high health pool means their hard to beat but even a basic bow and arrow can kill them if you can't fight then run they deal considerably high damage and can destroy your basic wooden shield in 5-9 hits of it's tail melee combat isn't advised but if you can manoeuver constantly and attack it's blind spot you got a chance
