It you put them on aggressive and perch em on your shoulder, they warn you of any danger with a scream. Usually it’s a diplo or a compy. If it weren’t for my dimo I would’ve died hundreds of times, he once yelled so I left and the next day i went back and say a giga killing a pack of raptors.
I tamed a lvl 15 female one and named it Nova and she was really good. She killed a whole pack of lvl 20 carbonemys without taking any damage and I didn’t do anything except stand there and watch in shock and awe. This is a MUST tame for everyone who reads this. I was only lvl 10 at the time I tamed it and now I’m lvl 40 and this creature has never failed to impress me.
When taming in pve, if there are too many columns from another tribe and you can’t use spikes, take 5 of these. Put them all on follow and one on aggressive, they will destroy anything that comes near. Leave a tame weighted down on affront, then make the Dino’s follow the tame, they will stay and protect the area while you are away waiting to starve it out. Too op not to have!! Use the same setup for a passive meat farm, just stop by and empty inventories.
