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.
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.
When you encounter a wild Carnotaurus in or near a forest, walk towards him, so that he is between you and the trees. He will go away from you to attack you with his charge run attack. By doing so he has a high chance of getting stuck between the trees. Now you can knock him out savely. But remember to chop down the trees when he is knocked out, because when he is tamed he will start running and bugging when the trees are still there.
When I first encountered a carno I had a lucky escape.it attacked from behind and sent me flying and I did not know what hit me but I ran until I fell of a cliff the carno followed and got stuck so get them stuck.
Large bear traps are the most under used thing in the game. Get like 7 or 8 of the large variety and when you see a carno put one down between you and it, agro it, shoot transfer and rinse and repeat till he's down.
A Very under rated tame. High lvl Carno with a decent rider is capable of huge destruction. My Carno Hugo can take 3 theri and multiple troodons at once and not even bat an eye. Hes even took low lvl rex. A must have early game and even mid/end game is still a reliable mount.
I'm taming one right now actually they are very easy to tame even at lv 50 just use a platform higher than they and you should be good lol I use my neighbors boat XD it takes along time to tame but worth it you need meat to tame at least or get special items for after tame
One attacked me while I was taming a baryonyx. I was able to take it out with a crossbow and pike, but If your any lower level than that you better run around other dinos and hope you have enough stamina.
The Redwoods on the Center is the best place to find high level Carnos. Most of them are in the upper 90s, with the exception of a few level 45s.
Carlos are really great all around if you can get past their horrendous stamina recovery
WILD Carnos are just 0.5 units faster than a player with no points in speed, 892 vs. 892.5
If you have one point in movement speed, you should just be able to outrun wild Carnos, but don't count on it.
I hate these things more than I hate taxes. Get movement speed to a solid 134%. I've found that you can out run them with that. If you're in red wood run to a dire bear for safety even if it's wild just don't go too close. I've never seen a carno kill a bear. Collect the carno's prime after this and enjoy ;).
