The best way I tamed my own was to lead it into an old fashion trap(4x1 or 2). As long as you are out of reach from the creature standing from a pretty good distance, Deinosuchus will either go into a basking mode(it's head slightly tilted, very difficult to guess) or the easier when it's mouth opens wide, although sometimes be mindful if the mouth is not trembling as it means it will bite. The rest is simple, providing the food, run when it does an animation, wait, and repeat, your only enemy will either be time or other hostile dinosaurs

If you are trying to tame one on the center if it is near the snow area I suggest bringing it towards the lower part because there are little dinos near it and the deinosuchus should be able to kill anything that might mess with you. Once you do this bring it towards rocks and it should get stuck and should be very easy to tame as long as you have kibble.

You have to be level 70 to even try to tame one

If your not looking to make a trap for this beast,the best thing to do is get your argy and land near as its mouth is opened(NOT WHEN IT IS CHARGING A GIGA BITE).I recommend full ghillie and have superior or better kibble.Crouch towards it and feed it near the mouth.If it doesn’t instantly tame run back to your argy and repeat.Hopes this helps!

Put food in last slot and feed it after it opens its mouth and hisses. It’ll chomp down if you do it right, sometimes the prompt doesn’t work but you can still feed it. Then run away and wait about 30sec and try again. If your not dying your doing it right. Good luck

For those curious, yes you can drop deinosuchus in a pen and still passive tame it. I just tamed a level 140 this way in ASA, using a quetzal to airlift. Pen was 3x3 and 2 walls high (I switched the walls to single doorways, don't know if that mattered). About half its body will clip out of the pen, so you can access the head without going inside the pen.

It would hiss, open its mouth, and I'd come up near its head from the side to feed it quickly. Once you're close enough to the head look back towards its neck/body a little to see the Feed prompt. It chomps down when you feed it, then tries to chase you. Just step away from the pen and wait for it to settle down. Wait for it to hiss and open its mouth again. Rinse and repeat.

Only issue I had was the gator sat there completely motionless for several minutes until I went near her and got her to aggro and move around a bit.

Building a trap for it is quite easy. a 4 by 4 foundation, line it with doorframes and ramps. once it basks feed it with mutton or prime meat if you dont have kibble. After about 20-30 minutes its tamed.

Net gun does work I tried it myself

To effectively tame the Deinosuchus, the crocodilian stronger than a Rex and better equipped underwater than a Spino;

1. Look for them around the swamp biomes (at least on The Island), they usually can defeat any other Dino, so these guys are usually crawling all over the place, they’re the kings of the swamp.

2. Using FULL GHILLIE, as well as preferably bringing a shield and bug repellent, make sure to crouch walk towards the deinosuchus when it does the opening mouth animation and sitting still. Walking/Running up to it will result in getting detected, however proning is far too slow, so crouch when within 8-10 meters.

3. Using preferably kibble (as even mutton or prime meat will be slower than you’d expect) put it in your last slot and get ready to hand feed it like you would a passive tame. When you feed it, its mouth will slam shut. If you did it right, you won’t get obliterated (hold up shield in case it chomps down and you may yet survive), and there will even be a 3-4 second window where you can run preferably 20 meters away and it won’t aggro.

4. Repeat steps 2 and 3 until tamed

ALTERNATIVE METHOD (REQUIRES A DINO LIKE THE QUETZAL OR RHYGNIOGNATHA THAT CAN PICK YP THE DEINOSUCHUS)

1. Pick the Deinosuchus of your choice with your flyer.

2. Have a pre-constructed trap box at your base or wherever you like.

3. Fly to your trap box and drop it in, make sure box is big enough.

4. Now you can easily tame it in a safe, controlled setting.

Congratulations! You have tamed one of the strongest boss killers in the game! Good luck with your taming, and don’t get chomped!
