This course focuses on the geological and evolutionary processes that have shaped our planet and life on it over the last 550 million years, the long, fossil-rich period known as the Phanerozoic. Using Indiana as the focus, you will learn about the evolutionary history of major groups of animals and plants, the origins of life on land, the growth of the North American continent, changes to the Earth's atmosphere and oceans, and the interactions among life, climate, sediments, and geological structures.

Acadian orogeny

A middle Paleozoic mountain building episode, the climax of which was in the Late Devonian. The Acadian Orogeny occurred when the microcontinent of Avalonia collided with the eastern coast of Laurentia (North America). The Acadian orogeny was the second episode of mountain building that formed what are now known as the Appalachian Mountains, occurring after the Taconic Orogeny.

Hoosier paleontologists

Charles Schuchert

Schuchert was a prominent paleontologist originally from Cincinnati Ohio. As a geologist he was largely self-educated and started his career illustrating fossils for early geological surveys. He later worked as a preparator at Yale University, then worked at the US Geological Survey before joining the faculty at Yale, where he remained the rest of his career. He was president of the Geological Society of America (1922). The Schuchert Award is given by the Paleontological Society in his honor to a person under 40 whose work reflects excellence and promise in the field.
