Get it to agro on your arge then knock it out

If you are going to tame one of these with no dinos, be sure to upgrade your movement speed and get tranqs. When you see it whip its tail forwards move to the right you will dodge the shots. This worked for me.

Thorny dragon can act as a turret, set tange to high, fill it up with stone so it cant move and set to aggressive. It is beaver version in desert,doesnt collect berries thoe.

Completely irrelevant but I think it looks kinda cute.

Argent can pick it up now after tlc 2
