Meet Dr. Matthew Carrano, a paleontologist at the National Museum of Natural History. Why does he sort through drawers upon drawers of tiny fossils? Watch how Matthew pieces together the evidence of ecosystems that dinosaurs lived in. Learn what tiny fossils can reveal that complete, large dinosaur skeletons may not. Get a glimpse into technologies such as cathode ray luminescence that have made detailed analysis of tiny fossils possible. Understand how paleontologists are collaborating to map worldwide dinosaur distributions.
