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

UP IF IT HELPS

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.

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.

If you have a flyer carry one to a taming pen, it's gonna aggro and start throwing spines at everything it sees the minute it lands. Plan accordingly, and use solid walls so it can't shoot through them.

Argent can pick it up now after tlc 2

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

If your play scorched earth and you see one follow these 3 steps to survive first they are like the troodon in day it takes around 8 to 12 seconds to aggro and has a small Aggro range which means you can run right pass them. Next if you want to tame them at a starter level around 12-21 climb on a rock that you have to jump on like do parcore

For me I tamed him on ark fjurdur in balheimr I used a argentavis to go to a high area and then I started shooting him with tranq arrows it took me like 14-15 tranq arrows then I gave him raw prime meat and then I tamed him. Hope this helped. Good luck for everyone taming him.
