When I first player aberration I tamed one of these and a bulbdog. Then a pack of craptors killed me and my bulbdog and when I went to recover my stuff He was still fighting them and even killed one. I had understimated him and he became my main mount for a long time. Even after I got a karkinos he was still useful and will survive anything. I used him to tame the paracer needed to tame a karkinos as well as a sarco. If I were to leave him in the element zone on wander and neutral chances are he would survive. He helped kill the pack of ravagers that killed my first aberrant iguanodon and helped kill many spinos and karkinos. He alerted me that there was a karkinos in the lake surrounding my base which attacked my dinos which inspired me to tame electrophorus, angler fish, and mantas to guard the lake from karkinos and spinos. A high level parasaur can kill a carno and outrun a spino.
