Use a sword. I was on brutal trying to tame a level 205 and when I hit it a whole swarm of mabye 7 came after me my apprentice sword killed them all (note I had full ascendant leather armor)

Don’t piss them off at the north redwood river in mobile. A whole swarm will come after you if you do.

Valguero aberrant area, specifically in the radiation zone now spawns aberrant versions of these guys.

For all you beginners out there do not just randomly attack these guys and expect a easy fight once you hit one a whole army will go after you killing you and probably your take you brought with you. Up so beginners can see.

player attacks one of them (rookie mistake💀💀)(new player behavior 💀💀💀💀💀)

I went to raid a base with 4 buddies, a rex, 3 carnos, and a bronto with a platform saddle and cannons. All we heard was a whistle and i swear about 50 of these little devil's swarmed the whole group, killing everyone in the group and one carno, the turrets shredded everything else, but the rex must have ran off and we never got a death message so its still out there in the jungle.

A tip for beginners:

If you attack these guys with your dinosaur be warned...

Even during riding your Mount, they will kill you first, not your dinosaur…

And they do tons of damage and are not that easy to hit with smaller dinosaurs (small hitbox)

Try to avoid them early game

Get a C4 and attach it to one of these and then whistle attack. "Hunter killer drone deployed!"

When in areas that have many dimorphadon remember to be careful and not to hit one by accident when fighting other creatures as you can easily be overwhelmed.your mount will not be able to save you as they deal damage directly to the rider.
