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.

These creatures are dangerous me and my friend died multiple times just trying to walk away from it.

Completely irrelevant but I think it looks kinda cute.

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.

I built 3x2 stone foundation put stone door ways all around it then I put stairs on one side outside side by side so the dragon can run up

Make it chase you

run up your stairs/ramp

Once it come in run out a door way

Go back on stairs outside n shoot with tranqs

My level 85 took 22 tranqs

Also used same pen to tame X trike n pretty much anything that can’t fit through the door ways

To get one find one with a baby then kill the mother with a bow or spears. That’s how I got my level 50 fully imprinted one

Argent can pick it up now after tlc 2

Be sure and name your first Thorny Dragon "Me So Thorny." Epic.

These guys can easily be killed when you are trying to tame it with a normal crossbow. Of course space the shots out by 5 seconds. Whether they are in a taming pen or I am tranqing them while riding another tame it doesn't hurt to kill a wild creature and make it attack you will standing over the creature it should eat it and heal up making the tame process less worrisome.
