Jurassic Period Dinosaurs

Click on any of the pictures or names above to learn specifically about that particular dinosaur of this period. The Jurassic life is the time period of 203 to 135 million years ago. Evolution has begun to develop excessively. Not only for dinosaurs either. Flying creatures called Pterosaurs started to soar in the air. The dinosaurs of the Jurassic era were very large but there were a share of smaller ones as well. This is the most popular period thanks to Universal studio's top hit movie "Jurassic Park" which brought a whole new perception on how people see dinosaurs, but was somewhat of a bad influence for education because of the mass made up facts that were presented with dinosaurs within the movie.
