Abstract
We report four species of Marattiaceae from upper Permian deposits in the Dead Sea region, Jordan that are assigned to the genera Dizeugotheca Archangelsky et de la Sota 1961 and Qasimia Hill et al. 1985. The generic name Gemellitheca Wagner et al., 1985 appears to be a synonym of Dizeugotheca and the new combination Dizeugotheca saudica is proposed. The new species Qasimia archangelskyi is described. Early Marattiaceae were apparently monocaulous trees like Psaroniaceae. Marattiaceae strongly diversified in the Triassic but had already started to replace the latter group in the Permian.
