The most simple and easiest way to knock out and trap is use 4 metal billboards and make a square around the rhino. Its Super easy to trap it since you don't need to attack it till it's trapped.

The heart near the health bar isn't a rage meter like the giga it's a momentum meter for his charge and when it stop flashing and stays a solid red that means it's fully charged

On survival evolved all you need is tranq arrows a dino that you can shoot while riding it, and its preferred kibble or meoberries. Mainly I would do the kibble because meoberries take a long time to tame it and wastes alot of narcotics.

Tamed rhinos do more charge damage than wild ones.

When KOing just run in circles filling it with tranq arrows or darts(high level) this is the way to cheese this Dino’s taming. Even someone that just got into a world with good movement speed could do it easy. And the Dino’s are super op when fully charged. This will help ALOT :)

If you tame a high level and upgrade melee and stamina it is possible to enrage a giga with only a few full speed dashes

They can't fit into dino gateway

Just build a small 3x3 taming pen with stairs leading in from the outside then hit it with a tranq dart or arrow and jump on and argy and repeat until it’s in the pen then just keep hitting it with tranqs

Guys if are into taming this Dino mammal then be careful because at the beginning it is slow but it will get faster eventually.Whatever it is worth taming
