A fossil the size of our pinky nail is not typically what we hope to see when we come to a natural history museum to learn about dinosaurs. But it is exactly those tiny fossils that are paving the way for a new understanding of where and how dinosaurs lived.
 
In the fervor to find skeletons of the large dinosaurs that roamed Earth during the Jurassic and Cretaceous, paleontologists have been probing fossil formations for more than a century. Huge skeletons of Tyrannosaurus, Stegosaurus and other iconic dinosaurs have been unearthed. They have provided the foundation for research on what dinosaurs looked like, what they ate and how they moved.
 
However, those characteristics of big dinosaurs are only part of the story.
 
Like animals today, dinosaurs lived in complex environments populated by many smaller species. Dinosaurs depended on their more diminutive community members for food and functioning ecosystems. Many dinosaurs were themselves rather small, like dog-sized dromaeosaurs who roamed the United States during the Cretaceous. And, of course, even giant dinosaurs started life as little hatchlings.
 
Some paleontologists are combing fossil formations for the hordes of tiny fossils left over from dinosaur communities that lived millions of years ago.
