Abstract
Compressed fossilized foliage most comparable to that of Eremopteris zamioides (Bertrand) Kidston occurs in shale associated with coal in the Allegheny Group in northern Pennsylvania. In association with this foliage are abundant samaropsid seeds and small, apparently microsporangiate organs. Although close proximity of disconnected plant parts as fossils is not evidence in itself that these plant parts were originally connected, it is tempting to believe that these leaves, seeds, and microsporangia were parts of the same species. Furthermore, there have been a number of previous reports associating samaropsid seeds with Eremopteris. Additional frondlike structures with the same basic construction as the vegetative eremopterid leaves have been found; these offer information concerning the possible mode of attachment of the fertile organs.
