Just soloed one on foot. Followed it near volcano and just used a Bolo. No ghillie necessary. Mine was level 95 and I has to use three bolos total to take it out with tranq arrows. I'd recommend darts to be safe as my arrows almost killed it. BUILD A CAGE AROUND IT. Play it safe with this one, it's worth it. Just bring a pick and a hatchet with you and made wood fence foundations and thatch walls 2 high. Should be good.
Go to extinction into the city area. Bola the Tapejara. Place stone gates around five or four stone gates with gateways with just small gaps in between the gate. You place this down fast. You can tranq it or club it.
If you are going to try tame one get a gille suit on sneak up behind it and bola it if you don’t have a longneck you can use whatever weapon you want and if you want a longer lasting bola use the chain one!
