The Paleobotanical Collections Database has over 77,000 entries and encompasses all aspects of the paleobotanical collections at the University of Kansas, including permineralized and compression/impression specimens, prepared slides, teaching slides, research slides, figured negatives from published papers, and figured and duplicate peels. The collections consist of tens of thousands of specimens with a large percentage being made up of Permian, Triassic and Jurassic silicified peats and compression/impression plant fossils from Antarctica. We currently house the largest collection of Antarctic fossil plants in the world with more than 7000 specimens from throughout the Transantarctic Mountains. There is a large collection of Carboniferous coal balls from Kentucky, Illinois and Kansas, and a number of specimens from the Devonian Rhynie chert of Scotland and the Pennsylvanian Mazon Creek nodules of Illinois. The remainder of the collection consists of plant fossils from numerous localities around the world. The collection is housed in an all metal compactor system which was purchased with the assistance of the National Science Foundation, the Natural History Museum and Biodiversity Research Center, and the University of Kansas.
