Cretaceous Plants and More

Cretaceous Time Period

• 99.6 -145.5 million years ago. The last time period in which dinosaurs walked the Earth. For example...
• Herbivores: Triceratops, Corythosaurus, Iguanadon
• Carnivores: Tyrannosaurus Rex, Veliciraptor
• Omnivores: Gallimimus, Ornithomimus

Cretaceous Time Period

• The Earth's climate changed and Earth began to have seasons, which meant colder winters and warmer summers. These changes in temperature meant lots of changes to the plant life.
