Local Discoveries: Case: Dinosaurs in Our Backyard (opened April 28, 2010): From 225 to 65 million years ago, dinosaurs lived everywhere on Earth—including around Washington, D.C. This case explores how scientists piece together information about dinosaur biology, ecology, and evolution from fossil specimens and reveals the important contributions amateur collectors make to the museum's collections and knowledge. It features a unique skeleton impression of a baby dinosaur of a species new to science.
