 | LUPIA, R., H. PRYER, and P.R. Marsileaceae sporocarps and spores from the Late Cretaceous of Georgia, U.S.A. International Journal of Plant Sciences 161: 975-988. |
| Monomegasporangy (single megaspore/megasporangium) is assumed to be one of the key innovations in the evolution of seed plants. |
| On the basis of shared morphological features of the sporocarp wall structure, and in situ megaspore and microspore ultrastructure and ornamentation, these specimens are assigned to the water fern family, Marsileaceae. |
