I will show you how to Trap everything in ARK Survival Ascended!
This video is how to Trap and Tame a T-Rex.
The Rex is needed for the Master Zoologist Achievement/Trophy.
Equipping a tamed Rex with a saddle and riding it will unlock you the Rex Rider Achievement/Trophy.
The Rex Trap consists of 4 Foundations, 8 Walls which will be Double Doorframes and 4 Sloped Rooves, which will be used as Ramps.
This is the simplest way i could think of to trap this beast without making things too intricate or complicated. It is a simple box trap, the Rex will try and avoid the trap if you jump in too early, so hold your nerve and wait until the last second to successfully lure it into the trap.
The T-Rex is one of the top 5, maybe even top 3, Dinosaurs in the game for Boss Battles, with high Health and Attack stats, the Rex isn't beaten by much on the Island.
