The Discovery of the Dinosaurs

by Jan Leyssens

Published 14 October 2021

The early nineteenth century. Mary Anning is only twelve years old when she discovers her first dinosaur skeleton while looking for fossils to sell. It isn’t just any skeleton; it’s the first almost complete Ichthyosaurus ever found. Over the next few years, more dinosaurs follow. Although Mary doesn’t get admitted to a university, her research would later form the basis for developing the theory of evolution, which made Mary one of the most important paleontologists in history.
