Instructions

Professor Luce found the fossilised bones of 4 dinosaurs. The drawings show what he thinks the dinosaurs looked like.


He now has to decide whether the dinosaurs he found are meat-eaters or plant-eaters. He has made a list of features of meat-eaters and plant-eaters to help him.

Professor Luce has asked his team of assistants (you) to look at his drawings and use the list to decide which group each dinosaur belongs to. You will need to give as much evidence as you can to back up your decisions.
