Tylosaurus - Predator of the Deep
Salutations young reader! Today we are going to embark on a journey back to the age of the dinosaurs. The dinosaurs are some of the most incredible animals that ever lived on our planet. They lived nearly 200 million years ago and thrived for about 165 million years. We humans have only been around for about 60,000 years and we have only been using computers for about 75 years.
