Focus: Fossil Plants

A re-creation of a Pennsylvanian Coal Swamp, with surprisingly tall ferns, horsetails, and lycophytes that dominated tropical Carboniferous forests.

The Paleobotany Collection spans 3.8 billion years of history but has its major strengths in the Late Paleozoic and Cretaceous-Paleogene. Current research focuses on the evolution of fire systems in deep time, with emphasis on this phenomenon in coal-forming environments and its impact on Earth system processes, particularly fluctuations in atmospheric oxygen concentrations throughout the Phanerozoic.
