If you don't want to waste your time kiting the beast to a cliff, just place four dinasour gates around it when it stops moving, then put it out. Best part is if you demo your gates you only need 2 more to repeat the process
I recommend taming this as soon as you get the saddle! They’re a super easy tame, use a crossbow with about 25-80 depending on the level, hop on a pteranodon after shooting it once, land, hop off, shoot it more, rinse and repeat till KO. If you have boosted taming time, just use mejos and it’ll work fine. Up if this helped!
