I highly recommend getting up high on a boulder or getting the carno stuck somewhere while knocking it out. Unless you are a high level, you will not be able to outrun it.

If you get one aggro on you, just find the nearest dino and book it. They are kinda tarded and lose interest when other dinos are nearby.

Tamed carnos are excellent almost all around: their health, attack speed, and base damage allow you to take on most of the creatures on the island, including Rexes and Alpha Raptors. Having a mated pair greatly strengthens this quality. They run fairly fast and can carry a lot, making great transport mounts. They are a fairly good harvester of meat and prime meat.
Their only real disadvantage is a slow stamina regen, even when stood completely still.

If you're not sure if it's a carno in the wild, here's how you tell, 1.) their arms look like they've been put through a blender. 2.) they run like autistic rexes.

It must be hard to grab the tv remote with those arms

Drop a large bear trap, stand behind it, aggro the carno with a ranged weapon, draw into trap and just backup and down it.

Probably your first canivore and it will make you feel like your the best of the best, or is that just me!?!?!

Get a jerboa and name it carno bait, if one aggros on you, toss it and boogie

run into shallow water that you can walk in and go prone and the carno will lose agro this works for terror birds to.

Doesn't get stuck as easily as the larger carnivores

But wait...
How could he crack open a cold one with the boys with those arms??

Aladar ain't gonna help you this time buddy. Be safe, bring a friend-as a distraction, of course.

If you have a flyer get on a rock the carno can't reach or on multiplayer get a friend and a flyer and grab your friend and let him/she shoot the carno with anything that has torpor

Rated number one for gathering prime on wiki

My level 223 carno regularly kills level 150 Spinos, therizinosaurus, and rexes. Sometimes multiple at the same time. Tame a high level and get your melee around 500%+ and you have an alpha killer.

Just killed a Carno with a pike by running around in circles with it #Legendary

Carnos can be used for cave expeditions, especially central cave where they can right click attack everything. Just get out before night!

Use a raptor as a mount and you can easily outrun a Carno while shooting it with tranq arrows/darts. It's how I've tamed all my carnos.

Very useful mid-late game, I have a carno lvl 218 with 4 raptors lvl 180+ and they can escort me anywhere. They kill Rex's like is no big deal. The only thing we can't defeat are titans. The day will come......

Having a pack of Dilos is a good way to combat one early on: they can slow it down with their spit attack, they can be generally hard for it to consistently hit, and carnos focus more on dinos than humans so if you get ambushed chances are it might change focus to your dilos. It can be possible to kill a carno with just 2 dilos if they can take a hit and you provide cover fire with any ranged option.
