Tyra, one of Equestria’s leading experts in paleontology, deals in the business of digging up ancient graves. She’s a seasoned paleontologist with plenty of years of experience and a good team backing her up. Although she is accustomed to dealing with bones, she is no stranger to magically regenerated dinosaurs. She knows that they are docile creatures, their minds tampered with by the magic of their peaceful re-creators.

But one day, she discovers a creature that is all too real. It has no hint of magic in its blood. It is incredibly fast, agile, and cunning. Every single successful hit it delivers is destructive to the bodies of it's adversaries. And she and her team are the only ones with the expertise to stop it from its silent rampage across the countryside.
