Eospermatopteris fossils

Joe Chergosky and Brad Petrick (not pictured), with Physical Facilities, help Laurie Rasperek, manager of the E.W. Heier Teaching and Research Greenhouse at Science 3, Associate Professor of Biological Sciences William Stein and Kuhdadad, a PhD student from Pakistan, place two Eospermatopteris fossils from fossil stumps discovered in the 1870s near Gilboa, N.Y. at the greenhouse. Stein believes the 300-lb. fossils are between 370 and 380 million years old.
