I was a T-rex

I was a T-rex alive during the Cretaceous period. The Cretaceous period was always warm and almost always had high sea levels. I loved to eat meat and would tend to eat other dinosaurs like Edmontosaurus. I use to live in North America and would never be caught dead in South America. These facts have kept me alive throughout history, plus other factors such as the size of my body, about five tons and my tiny limbs.
