Some fossils even give clues about how ancient organisms went about their daily lives. For example, fossil footprints suggest some dinosaurs lived in groups.
Why are dinosaurs so special?
They evolved diverse shapes and sizes, from the fearsome giant Spinosaurus to the chicken-sized Microraptor, and were able to survive in a variety of ecosystems. One of the reasons for dinosaurs’ success is that they had straight back legs, perpendicular to their bodies.
