I think they are broken rn. I was taming a 140 put 100 tranq arrows in it with a 218 damage crossbow. And it’s the second one in a row that did that to me. Like after they go into their shell and then come back out they don’t move. They are broken.
I was flying my pteranodon, and i saw a lvl 27 rex pick on one of these lil cuties. He curled up into a ball, and took no damage, so combined with its mining capabilities, this lil guy is perfect for the mountains, as they have incredible defense, and mining capabilities.
