So my experience with this beast was horrifying but I knocked it out it took so much tranq arrows it took 30 tranq arrows and I ran fast with the Brontos because there were lots of dinos with the brontosaurus then it was attacking the other dinos then I shot it a lot then it fell asleep because the thing it was attacking a a tank it was an ankylo so that’s my experience with a rex.
