I got a rex in a funny way, I was taming a therizino with a trap, when the therizino fainted a rex appeared, and he caught the trap that wasn't for him, I managed to knock him down, but I had to get a lot of meat, and in this process I died 5 times because there were allosaurs around, and I was trying to defend him when he acrobated I took him to my base and left him in aggressive mode to protect the base, because many carnivorous and aggressive dinos came in, resulting in the loss of several, but he protected his base well, before leaving..
