Order Cordaitales


Foliage

Leaves of the fossil gymnosperm Cordaites lingulatus from the Carboniferous of Luzerne County, Pennsylvania (PRI 50480). Specimen is on display at the Museum of the Earth, Ithaca, New York.


Seeds

Fossil specimens of Cordaicarpon sp. from the Pennsylvanian of Michigan. Cordaicarpon is a genus of seeds (the circular structures, one indicated by an orange arrow drawn on the specimen). The associated parallel-veined leaves are also from a cordaitalean plant. Cordaitales are a Paleozoic order related to conifers. Specimen is from the Cornell University Paleobotanical Collection (CUPC), Ithaca, New York (#1213.3). Length of rock is approximately 14.5 cm.
