First dino I ever tamed and bred. In my opinion its a slow breeder. But hell of a defender. Its just a good tame all around especially due to the fact its 10x better then a trike (in defense) and the saddle is relatively easy to unlock. Plus its got a cool swimming animation.
Whoever said its a fridge on legs is wrong, these guys don't slow the spoil time any more than your average tame. I tried to refrigerate mutton and it didn't work, now I have to find another ovis to tame my spino.
