From left to right: a late Carboniferous rainforest community from over 300 million years ago; a dinosaur-dominated wetland community in eastern North America during the Early-Middle Cretaceous, 110 million years ago; and a mammal-dominated community in North America during the Miocene, about 15 million years ago.
