Dinosaurs are reptilian creatures that lived during the Mesozoic Era. They lived on Club Penguin Island during that time, along with Dinosaur Island. The island looked very different, covered in jungles, dirt, and volcanoes. There were many different dinosaurs, consisting of many different colors, shapes, and sizes. Some had wings (but they could only glide, not fly; some of them could not glide). Some were carnivores, some herbivores. Some even had feathers, but still could not fly. Today, non avian dinosaurs (dinosaurs that are not birds) don't exist, as they became extinct. The only place dinosaurs still exist, in the Club Penguin universe, at least, is Dinosaur Island, which could be explored during the party Rockhopper's Quest. Scientists do not have very much information on them, due to them living long ago. However, one present day Penguin scientist named Gary the Gadget Guy invented a time machine, the Time Trekker 3000, to visit Club Penguin island during the Mesozoic Era, in which he and other penguins encounter many dinosaurs, and learned more about them. He did this once again for the Prehistoric Party 2014.
