Review of Palaeobotany and Palynology, 2010
Abstract Two conifer species from the Upper Turonian of the Saxonian and North Bohemian parts of the Bohemian Cretaceous Basin are redescribed using the type specimens and additional material from the type horizon. In both cases characters of the gross-morphology of foliage shoots and leaf epidermal cell structure observed by LM and SEM are studied.

The study of conifer twigs from the Middle Jurassic deposits of the Irkutsk Coal Basin, previously described as Sequoia and Taxocladus, shows their morphology and epidermal characters to be similar to those of Marskea leaves. A new species Marskea heeriana N. Nosova et Kiritch. is described. A new combination, Marskea latifolia (Kiritch.) N.

Revision ofCunninghamia protokonishiiTanaietOnoe (Pinopsida, Cupressaceae) from East Asia
Paleontological Research, 2017Morphological and cuticular features of Cunninghamia protokonishii were examined by studying the original material and additional fossils that were collected from the lowest Miocene to the lower Pleistocene of Japan and Korea. The species is characterized by foliar morphology that superficially resembles C.
