19. Permian Life DioramaThis photograph of a Field Museum diorama of the ocean floor before the end-Permian mass extinction shows several simple, fixed organisms, including brachiopods, corrals and large yellow sponges. New research indicates that after the mass extinction that marks the divide between the Paleozoic and Mesozoic, complex ecosystems largely displaced these simple ones.
