Dinosaurs types are many and varied, from small bird-like creatures to the largest animals ever to walk on Earth. The subject of blockbuster films, history museum exhibits and much more, dinosaurs continue to interest people today after first appearing approximately 230 million years ago. These vertebrate animals dominated the land for more than 160 million years before experiencing a catastrophic extinction at the end of the Cretaceous period 65 million years ago.
The first dinosaur was recognized in the 19th century and ever since, dinosaurs have been the source of many questions.

How is the modern bird connected to these prehistoric creatures? Could dinosaurs like Tyrannosaurus Rex and Brontosaurus really be brought back to life with mosquito DNA?
