C ridland , A rthur A. (Ohio State U., Columbus.) A Glossopteris flora from the Ohio Range, Antarctica. Amer. Jour. Bot. 50(2): 186–195. Illus. 1963.—Leaves of Glossopteris indica are the commonest fossils in the Mount Glossopteris Formation on Mount Schopf. Other fossils present are: Glossopteris ampla, G. anguslifolia, G. damudica, G. browniana , detached scales, sporangia of Arberiella containing bisaccate pollen grains, seeds of Samaropsis (principally S. longii) , and some obscure fossils. These remains, and associated animal fossils, suggest that the Mount Glossopteris Formation is Permian. The plants evidently grew in a seasonal but favorable climate. These growth conditions indirectly support paleomagnetic calculations which indicate that in Late Permian time, Mount Schopf lay near latitude 50°S.
