From these pictures alone, students should draw what they think the relevant dinosaurs looked like. You may also ask them to research a particular dinosaur or fossil find. If possible, they should read and compare what two different scientists say about the same dinosaur. Because the evidence is scarce, scientists rarely agree on what dinosaurs looked or acted like. Back to Top 1.
Some scientists think that pterosaurs walked on all fours.
Other scientists think that they walked upright. Using pictures of pterosaurs and pterosaur skeletons, decide which idea you think is right. Use what you see in the pictures to support your choice. For each of the activities, students should be evaluated on how well they can support their conclusions about dinosaurs and dinosaur behavior. When their work is complete, have students attempt to identify the plants and animals that each other's fossils were made from.
