As a paleobotanist, Kathleen Pigg primarily studies plant fossils from the past 65 million years that are found in western North America. Her research team is investigating the evolution, biogeographic distribution and adaptations of major flowering plant groups. They collect and study fossilized fruits, seeds, flowers and leaves and compare them with those of modern relatives.

Pigg’s research group is studying the evolution of dormancy mechanisms by examining fossil plants from northeastern Washington, found in an area that was a higher elevation than other coastal areas during warm, Eocene times. These fossils are early examples of temperate plants such as maples, birches and the rose family.

This research will help the team learn about the evolutionary mechanisms of temperate plants —plants that today, face the challenges of global warming.
