Let's get straight to the point. Kentrosaurus is going to be a cut above. It's piercing gaze alone will be enough to send even the largest carnivores running. It will slash the competition. Tribes would be foolish not to stick this in their arsenal. It may be a hard tame, but I'll take a stab at it. Did I mention that it's pointy?
Eats Compy Kibble. Usually spawn near the bottom of mountains. When using kibble, no narcotics are required. A level 80 will eat about 21 compy kibble during x1.5 on offical servers. About 7 tranq darts were used to take down the level 80
It's best to leave them alone unless you want to tame them. They act like spike walls, so you and your dino take damage when you melee it, and it's a lot of damage, even low level ones do a lot. If you want to kill one, it's best to use ranged attacks like a gun or a wyvern blast.
