In my experience I have found a couple of ways of taking these big boys down easily. The first one is to utilise it's turning circle as it cannot turn fast at all, so hug it's back legs, turn with it and whack it with some sort of melee weapon at the same time, a sword or pike works best for this. The second technique is to just walk backwards and shoot it with something, preferably something damaging, so I wouldn't suggest using a slingshot here. But doing this back step technique will allow you to just be too far away from the Sarco's bite, however, be careful of what can come sneaking up behind you. And by all means do not try and out swim this thing, it will win, every time.

These guys are really good early - mid game tames. They are decently fast in water and their stamina replenishes instantly when in the water. Although they are pretty slow on land. All you really need is some tranq arrows and no narcotics since their torpor drains slow. If you want to be extra safe when you tame one bring a flyer like a Pteradon or any flying creature you have at your disposal. But if you don’t want to you can just keep running until you knock it out. I personally tamed a lvl 135 and it only took 7 tranq darts and I didn’t need to feed it any narcotics to tame. Unfortunately it was 4 in the morning at the time and I had to go somewhere in about 2 hours so I was rushing to get as much sleep as I could. After it was done taming I named it and immediately left but my game crashed and I still don’t know if I have the Sarco or not but I assume no. Hope you find this a bit helpful.

on my 2nd day of ark (real time) and i saw a female sarco who looked exactly like swamp (my sarco who was killed by jellyfish in my resent world) so i made a little wooden box 4 big woden walls and a door frame i led the sarco aka swamp the 2nd and i KO it out with 2 slingshots and i has about 50 rocks of course i missed a few times it was lvl 18 just like swamp when she was killed now it’s lvl 30 and i’m lvl 27 and i also have a rex (saw blade), carno (toast), deadly trio aka my 3 raptors Ares, hunter, and the leader ivy and a parasaur (para) her boy friend died to a 140 massive chicken with big claws 😭. Dilo,(mini killer), one of those starter bird thingys (shadow bolt) , and my baba sarco i’m rasing up now named snappy and i for got how to spell it but his name means swamp in japanese he is snappy’s dad. Dada cherry and finally chicken (both dodos.) hope u enjoyed 🙂😊

I tamed one of these bois in a trap when it was level 80. I used it to get oil at sea because my base was on the beach. If you decide to do the same as me I will warn you one thing, stay clear of the jellyfish. They killed my sarco at level 138 it was defenseless because it got put to sleep. But it is good for quickly getting lots of oil early in the game, just make sure it’s safe.

Playing solo, can't recommend the Sarcosuchus enough. Tamed a level 76, it's 117 now, and now I own the rivers. A mid level Sarco can handle megalodons, mid level spinos, rexes, and at least low level alpha raptors. My higher lever Sarco hasn't met her match yet. I find combat with them to be awkward at times but they've got great health, stam regens underwater, and once you're in position they deal good damage quickly. Couldn't ask for a better early game mount.
