1. Flying reptiles were a very diverse group during the age of dinosaurs. However, although the present age might be considered the age of mammals, bats (the only flying mammals) exhibit far less diversity than did flying reptiles. Can you suggest as explanation for this?
2. If you were presented with a complete skeleton of a small reptile from the late Triassic, what one feature could you use to establish if the fossil is a dinosaur or a thecodont?
