Dinosaurs have captured the imagination of people for generations. These reptiles were the dominant species during the Mesozoic era and lived through three periods: the Triassic, Jurassic, and Cretaceous. With fossils dating back to over 230 million years ago, dinosaurs once roamed across the entire planet, from South America to Antarctica. These creatures’ remains provide valuable insights into understanding ancient biology, climate, and evolution. From the longest of necks to the strongest of bones, dinosaurs come in all shapes and sizes, having their unique adaptations for various environments. Though extinct, these creatures’ legacy remains on Earth, continuing to inspire and educate people worldwide.

As I researched and compiled this list of dinosaurs, I was fascinated by the sheer size and awesomeness of these creatures. And as I learned more about them, my appreciation for them deepened. Creating this list has been an incredible experience, and I am excited to share it with others.
