Dinosaurs are extinct animals which walked the earth a long time before humans came along. This means that we had no contact with dinosaurs before they were wiped off the face of the earth. But of course, with research and expert diggings, scientists have been able to find out a lot about these majestic and dangerous animals, and even give them names. The stegosaurus in this worksheet is a dinosaur that is covered in spikes. Help your students count the spikes on the dinosaur’s body, and then circle the correct answer.
