Dinosaurs are a group of reptile that dominated the terrestrial ecosystem for over 160 million years, from around 230 million years ago until 66 million years ago, at the end of the Cretaceous period[1], when all non-avian dinosaurs became extinct. Dinosaur remains have been found on every continent, including Antarctica, showing that all land masses were at one time connected in a supercontinent called Pangaea. Vertebrate paleontology has become a global science, with major new discoveries in previously unexploited regions, most significantly the well-preserved feathered dinosaurs in China which have further solidified the link between the extinct non-avian dinosaurs and birds, the present-day avian dinosaurs.
