Valguero aberrant area, specifically in the radiation zone now spawns aberrant versions of these guys. Up _vote so people can see!

I saw a flock take down a spino. Probably not by themselves, but it just goes to show that these things are not to be messed with in packs.

The thing with these birds is they always attack from behind. The only way to escape is to outrun it.

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.

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.
