These are probably speedier than a Gallimimus! I once saw one of these kill a running Moschops which are already speedy at full speed running! Can they attack while moving like the spider, though? Press the up button if yes but press the down button if no.
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.
I'm my opinion carnos are super good at being guard dogs and as a transport mount thier long range attack and the knock back on the head but move is super good at killing alpha raptor you should pump a level 1 with 10 levels
Try get a good level carno to do boss fights because of bleed damage but some bosses dont take bleed so be careful. These are tamed by the regular knockout method but do trap it. It's a good mid to late game tame
It is sad to see the Carno for not getting too much love these days. Whenever I try to find mutated Carno videos, it only shows a few of them before showing off Rex, Thyla, basically everything else except the Carno, and I'm disappointed. Carnos are basically a nerfed apex predator. They have the power and health you would expect while being speedy as well. They are not too difficult to tame, just a simple knock out tame. Even though a TLC could spice things up a bit, I love it for what it is.
After the TLC, Carnotaurus has become not only a more powerful mount but also a very dangerous encounter especially with their Yutyrannus leaders. The secondary attack causes a nasty bleed effect that drains the targets' health significantly. This paired with the significant knockback can easily kill many creatures with high health pools such as brontos and stegos. A fully imprinted, mate-boosted and mutated pack of carnos are a force to be reckoned with and can even take out Alpha Rexes.
