Dinosaurs were the first main animals on the planet Earth for more than 150 million years. They looked like lizard reptiles and some of them were quite large and scary. Even the word dinosaur comes from the greek word meaning terrible lizard. But those terrible lizards have died out about sixty-five and a half million years ago, and their first fossils have been discovered only in the 1800s. And those fossils could be found all over the world on every continent of the planet Earth. Dinosaures had different habits and ranged in size dramatically. Some were a size of a chicken and others as much as a hundred tons. A fanart animals custom progress bar for YouTube with Funny Dinosaur.
