Is It a Dinosaur?
and is replicated here as part of the SERC Pedagogic Service.
Course: Dinosaurs, Extinctions, and Disasters
One of the major misconceptions students have about dinosaurs is that anything large and extinct is a dinosaur. I show them a series of pictures of extinct animals and ask them to decide if it is a dinosaur or not. Some are easy while others are more difficult. After they are "stumped" a few times, then I go on to show the features that characterize all dinosaurs.
