The first time I encountered one of these asshats I was on my flying mount (Argentavis) with a Pteranodon escort. It ate us all before I had a chance to realize what happened. I was traveling with my dear sweet monkey Poogun. He was my first tame and my dearest friend. The bastard ate Poogun out of pure malice because there wasn't enough meet on him to fill its pinky toe. In an act of anger and vengeance I grabbed all of the Dimorphadons (over 50 of the winged monsters) and Raptors in my base and flew back on another argentavis with the intention of murdering the creature. The soul surviving dinosaur was the one sitting on my shoulder. Giganotosaurus ate well that day. I made poor decisions.
