"Plants in the Past: Fossils and the Future"

Present-day plant diversity is remarkably rich and varied, but the vast majority of plant species to have ever lived are now extinct. Knowledge of the past is key to understanding the origins of today’s plant diversity and to illuminating the fundamental evolutionary processes that generate biodiversity. The study of prehistoric floras (the fields of paleobotany and paleoecology) also provides key evidence for subjects such as paleozoology, the formation of the Earth’s atmosphere, and climate change.

The 16th Smithsonian Botanical Symposium, hosted by the Department of Botany and the United States Botanic Garden, will explore plants in the past, from their early origins to the more recent rise of the angiosperms. Speakers will address current trends and the future of paleobotanical research. The Symposium coincides with the development of the Natural History Museum’s Deep Time exhibit, a major overhaul of the National Fossil Hall, which is scheduled to open to the public in June 2019.

NOTE: Unlike previous years, the Symposium presentations will take place in the Warner Bros. Theater in Smithsonian’s National Museum of American History.
