They are part of the jungle spawn pool. To find go to either : south east coast up to green ob, also south and east of the foot of the volcano. West coast from red ob up to the river (not on beach, inland). If you see Rex or ankylo you are in the greenland biome. Wiki is full of shit, while they do indeed spawn in the redwood, the spawners there are set to 13 Dino's instead of the regular 23 a regular spawner would have.
They are on the rarer side of the spawn pool just a tiny bit less of them than carnos.
Story Time (I don’t know if this is the right category but watch ever)
Tapejaras are hard to find, hard to tame and hard to protect while taming, I discovered that in the hard way.
During my entire time playing Ark(mobile) I only seen 3 Tapejaras , I tried taming all of them.
The first one escaped because I ran out of food and narcotics.
The second one I tamed, and then he got killed by a Spino seconds later.
Due to luck and previous experience I managed to tame the third one , I named him Jack, and he still alive and I hope it keep on going like that .
Sooo, I hope this was useful, or at least entertaining, so what are you waiting? Go tame one! They really nice if they survive the tame they can survive almost everything I guess
Fly really high in the air and then if you have a tribemate and a flyer grapple hook to the flyer and then bola it just make sure you shoot it at least once while its in the air so just in case the bola breaks you dont need to shoot it that much so it knocks also level speed weight and health for a nice speedy flyer with good weight and if you get attacked you wont die unless its like turrets if your on a pvp server or pvx and in the pvp area
