We couldn't decide if the dinosaur was a Herbivore (can only eat plants), Omnivore (can eat both) or Carnivore (only eats meat). We decided that humans are omnivores, but some people decide to not eat meat. They are called Vegetarians.
We decided to try to trick the pesky dinosaur by leaving some delicious leaves, salad, cakes and meat. And whatever the dinosaur eats will give us a clue to what it is.
