Duckbilled Dinosaur Lower Jaw Section With 11 Large Teeth. Individual dinosaur teeth are rare, but jaw sections with original teeth still in place are usually only found in museums. This 3 ½x4½" lower jaw section is from a famous duckbilled dinosaur, Edmontosaurus. It was extracted from the 70 million year old Oldman formation in the Red Deer Valley of Alberta. The jaw is a rich chocolate brown color with eleven 1" dark brown teeth. Unlike mammals, dinosaurs continually replaced their teeth throughout their lives. This unusual fossil shows how tooth replacement occurred. From its side the outline of replacement teeth are clearly visible. As the teeth on top of the jaw were worn and lost, the teeth beneath them would rise to the surface of the jaw to take their place. Much information can be gained by studying this impressive and striking fossil jaw section. Add $15 for domestic shipping.
Estimated Value $400 - 650.
