Taming a carno is easy but knocking it out is very hard because it runs away fast when it is about to get knocked out. Best strat is to make a taming pen 2x2 stone platforms surrounded by stone door frames(2 walls high) and wooden ramps.

I used this way on Tanya the carno

Get it stuck in trees. That’s how I tamed my first Carnotaurus!

Very easy taming:
Step 1 look for scorpions
Step 2 tame
Step 3 mount it
Step 4 look for carno, rex, etc.
Step 5 just attack they dont agro insects (evil laugh)
Step 6 watch as they fall unconcious
Step 7 shove prime meat down their throat
Step 8 wait or roam around the map
Step 9 tap yourself for a job well done in taming
Step 10 become the boss of the whole island (evil laugh)

I use y trap on the carno and it work

A low level carno is actually easy to knock out I shot a lvl 10 3 times with my crossbow and boom, it was out I knocked out a lvl 90 with a crossbow and a longneck rifle. PROTECT THE NOOBS!

You do not need a trap just some tranq arrows and they are one of the best dinos to get

I killed o 3 of these suckers with 4 arrows i also sall a carno picking on a stego and the won with 3 tail shots

I was able to tame one by landing on a big rock and then I just kept shooting it with tranq arrows

I found a carbono I punch it I was new in the server I had nothin so when I punch carino it ran towards me then I ran towards a trick for it to kill it and take loot but it ingonered trick I punch it over and over in the but and it got stuck in tre and trick I knock it out but I had no meat and there was no other creature to kill for meat and I found an oncuancios raptor but I had no meat 😭😭😭😭😭😭😭😭😭😭😭😭😭😭

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.
