The best place to find theese is herbivore island /small tip:NEVER LEAVE UR DINOS ON AGRO THERE/
I suggest a raft to get there, bring some Dino’s too
There’s at least a single bronto there, but usually there’s two.
Bring at least a 500 berries, at least, plz do more tho
I also say u get some major soothing balm, and at least 60 tranqs,
