Very easy tame, just get mejoberries and feed them. I have four of these and I let them roam them around, next thing I know I have 5 stacks of thatch, 5 stacks of fiber, and 2 stacks of wood, and tons of berries :)
This guy is my favorite dino to start. It can farm LOTS of fiber, chitin, berries, rare mushrooms, rare flowers, polymer, etc. And it has a considerably good melee and health. But people don't see its value just because its a big coward iguana... Lmao. But for real, they're really one of the best dinos to get at the beginning, if not the best. Give this an up to let people know.
In Mobile you can't ride them so what I do is when I start a new save I just tame one or two low levels then I take them to somewhere near where I want to build my base and set them on wonder and just leave them there(make sure its a safe place so nothing will kill it) and while you do your stuff they'll gather decent amount of fiber (for early game)and once awhile I check them and take everything.it really saves a lot of time since you don't have a sickle early game. I REALY hope you find this useful
