Ever-changing Environments

Fossil Lake in the Past Worlds exhibit

From savannah plains to swamps to a lake-covered landscape, the area that would become Utah has featured many different environments throughout Earth’s history. These dramatic ecosystem changes happened slowly over thousands to millions of years, and with each change came a new chance for different animals to wander the lands. Explore the Past Worlds gallery to learn more about these changes and what they can tell us about how plants and animals survive in our continually changing world.
