Earth’s 4.5 billion-year history is a continuing saga of dynamic change. Events from ice ages to splitting continents influenced what survived, how life evolved, and what went extinct. See the only real dinosaur fossils on display in Washington state (including one of the best-preserved T. rex skulls in the world), intricate plant fossils that document past patterns of climate change, colossal mammals that roamed Washington state during the last Ice Age, and more in the Fossils Uncovered gallery. Discover how fossils reveal evidence of Earth’s transformation over time—and what the future might hold.
