Coating dinosaur bone with protective plaster cast
Dinosaurs lived as the dominant land animals during 140,000,000 years of the Earth's history. By studying their remains and the rocks in which they are found, paleontologists are able to make educated guesses as to what these animals looked like, what they ate, what kind of environments they lived in, and how they behaved. Here, paleontologists in western Montana enclose a protective plaster cast around a duckbill dinosaur found at a discovery site estimated to contain over 10,000 fossils.
