Lost my first sarco while trying to tame a therizinosaur, tamed a male and a female then I enabled their wandering so that they could make a baby at night. Woke up in the game only to find out they both slew two rexes then made them follow me just to suddenly notice that they have too much prime meat on themselves. Great hunter and slayer of enemies, just need to remember to tame two of them at once, a low level and a high level. Fun fact: When you are riding a sarco in the water and the stamina is finished up, it recharges in a second of rest. Better than a raft.
