Abstract

Several new fructifications and foliage specimens are described from four sites, in three southeast Queensland Early to Middle Mesozoic basins. This includes Paraxylopteris gen. nov., a likely pteridosperm fructification. Discovery of Paraxylopteris implies that inclusion of the foliage Xylopteris in Dicroidium cannot be supported. Pteridosperm remains described from the upper Ipswich Basin include the female fructification, Umkomasia geminata, the male fructification, Pteruchus dubius, and the foliage Dicroidium feistmantelii. It is likely that these remains were from the same plant. Also described are several conifer, cycadalean, equisetalean, lycopod and pteridophyte remains. Sedimentary conditions at the time of preservation are discussed.
