I tamed one using 3 stone battlements a behemoth gateway and 1 bear trap I got luck because my lure dino Bob the tapejara died in process but my strategy works as long as u have flyer mount to get on wall
It was just a normal day after I tamed my2cnd giga and I was walking around looking for some dimorphadons then I look up for a dimorphadon when i see a trike flying up in the sky
