On the island map they are uncommon spawns in many places although the best place to find them is in the south east jungle and obelisk area. They can be used to tame solo tame a quetzal. Kill a few ducks to get some ghille (2-3 pieces will do) then shoot it in the head and afterwards just hit it with a few body shot and it’s will ko. Never go to close on your mount when you find one. Flying mount reccomended. if it is in the air follow it from far away and wait patiently for it to come down. If it only ascends then don’t bother and if it’s on the ground land a little far away then equip ghille and shoot. I hope this helped!
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.
Can be found on scorched earth around red ark, to tame easy, use full gilli suit, bola fly around mountains until u see high lvl to tame, kill everything around it, making sure u don't spoil it, wait till it lands and make your advances, don't land too close or your mount will spoon it. Get bola ready, take aim and shoot. Shooting in the head will take down this tame nearly instantly
