A new series has scored 100 per cent on the review site Rotten Tomatoes and is at number one on Netflix. The mini-series is a four-episode Netflix documentary. It is called The Dinosaurs. It has powerful figures from Hollywood behind it. Superstar actor Morgan Freeman narrated it. Legendary director Steven Spielberg is the executive producer. He also directed the blockbuster movie Jurassic Park. Mr Spielberg used 50 experts on prehistory to help make the show. They recreated what life on Earth looked like between 235 million and 66 million years ago. The four episodes document how the earliest dinosaurs developed, survived for millions of years, and became extinct.

The producers used CGI to create the landscapes and dinosaurs. CGI designers recreated the ancient supercontinent of Pangea. This was a single land mass that slowly broke apart over tens of millions of years to form the continents of today. The designers also made volcanic eruptions, sand storms, floods, million-year-old forests, and (of course) the dinosaurs. The series starts with the birth of tiny dinosaurs. It ends with the enormous T. rex and triceratops, which Freeman says are "the most iconic dinosaurs of all time". It also shows us the asteroid impact event that killed off the dinosaurs. The Guardian newspaper reviewed the series. It said, "the geology and meteorology are powerfully rendered".
