Don't bother knocking out wild, they cannot be tamed in this method. Instead, steal the eggs from their nests. There are many methods for this, but the simplest is to lead the pack away with a swift mount, or simply wait until the pack has moved away from the nest. Be quick, as picking up an egg will draw aggro, the same as when picking up any wild spawned egg.

These nasty little beasts are absolute monsters in a pack, and can make quick work of any dino, so long as they can survive long enough to finish the job. They are excellent for land mobility as well, being extremely fast and having the ability to latch to vertical surfaces and jump up them for a rapid climb. They also have the only bleed effect in the game that stacks with itself and works on all creatures, including bosses. This makes them ideal for taking out the various arena bosses, such as the Dragon, Broodmother, and Mantacore, as well as seasonal raid bosses, such as the Dodorex and Dodowyvern. To cap these creatures off, they have a pounce ability that let's them latch on to larger dinos, making then hard to hit and impossible to escape from on large dinos.

Be cautious when dealing with these raptor-like creatures, because anything less than pinpoint precision can and will lead to a swift and painful death.

May the Obelisks Guide you.

Only obtained by searching for eggs, just like wyverns and drakes. Watch out for the pack though. They protect the nest and with their latching and bleeding abilities, they can be quite formidable. Either be quick about sneaking in and grabbing eggs, or kill them all. There is no in between...

Eggs are super easy to snag on multiplayer. Picked up my buddy with a Pteranodon and we flew around some ravines. Spotted a nest, made sure the coast was clear, dropped him into it and he picked up the egg, and I picked him up and flew off. Did this 5 times with no trouble. This is definitely doable on single player as well; just be extra careful and quicker.

Was able to fully imprint a lvl 120 🕺

The eggs need about 13-15 standing torches for it to be warm enough for them to incubate. Don’t stand near them for too long and watch the egg incubate unless you’re wearing ghille or have decent fortitude because you will overheat and die.

It’s pretty easy to tame these things you could use a flyer to bait the deinonychus away from the nests, but what I did was used an obelisk to bring a crystal wyvern to Valgero than I found a nest with only a couple of deinonychus killed them grabbed the egg and incubated it with like 15 to 20 torches. If you want to quickly get one I definitely recommend this only took me about a half hour to get one

I tamed (hatched) this thing at lvl 13, all I did was go to chalk hills 2, i empty out all my resources just in case I die and wait until the egg is fully unsupervised and boom, stolen eggo

mine was named Cliffwalker, but like all good things come to an end it died of a lvl 14.
