I tamed one in about 10 mins on herbi island. 5 mins of spamming tranq arrows and 5 of feeding it carrots with a minor soothing balm. Pretty easy tame for mobile. (Easy mode single player bc I'm too lazy to grind xp or sit round for 20 hrs watching a bronto tame 0.001% at a time)
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!
These are the easiest tame ever, just get far away, shoot it with a crossbow repeatedly, when it gets close run and shoot, then boom u knocked out a brontosaurus (I literally have 5 of them that’s how easy they are to tame) please
