  6. Parasaurolophuses • After the fire stopped in the north a couple of Parasaurolophuses(Say this Par-ah-saw-rol-oh-fus-es) survived. The Parasaurolophuses had hidden in a cave. A lot of them were hurt. All were hungry. The Parasaurolophuses slowly went out. It was dark and cold.

  7. Parasaurolophuses • All the other dinosaurs were bones. The Parasaurolophuses could not find plants to eat. They grew weaker . They began to die . There was only one left then it died.
