Dinosaur bones: How do we know their age?
Fossil dating is a lot like eating a delicious ice cream cake. Well, sort of. We find out how scientists look at the rock and elements AROUND a fossil to figure out its age. Plus: We talk to a scientist who studied one of the coolest fossils discovered recently: a dinosaur tail trapped in amber, complete with feathers!
Photos of the dinosaur tail in amber!
