Collections

Paleobotanical

The Paleobotanical Research Program fossil collection includes materials from the diverse history of plants. Vascular plant remains from the Carboniferous, Cretaceous, and Tertiary ages are part of the collection. This material has been acquired from various geographical regions across the United States. The paleobotany lab holds a collection of fossil leaves, wood, flowers, fruits, and pollen. Cretaceous specimens are preserved as 3D, fusinized fossils in an unlithified sandy-clay matrix. Tertiary fossils are preserved as carbonized impressions and flattened lignifications in lithified silicaceous siltstones and unlithified clays. The lab is set up for preparation, study, and preservation of these plant fossils, and serves the research projects of director William L. Crepet, visiting fellows, graduate, undergraduate students and his collaborators; Kevin C. Nixon and M. Alejandra Gandolfo.
