Abstract
Summary: Permineralization is a peculiar process of fossilization preserving anatomical details of plants of the Past, in some cases with a remarkable condition as represented by motile sperm in an Permian ovule. Here I introduce selected studies on permineralized plant remains emphasizing their importance in plant morphological studies to various extent. Ferns from the Eocene Princeton Chert Bed, Canada, Late Cretaceous plants from Japan, and a megasporangiate organ of Late Permian Glossopteris from Australia are mentioned.
