Article: Ginkgo foliage from the Jurassic of the Carpathian Basin
Mesophytic Ginkgo foliage from the Carpathian Basin (Romania and Hungary) is revised using a new statistical method for identification. The genera Ginkgoites and Baiera are suppressed in favour of Ginkgo. New combinations G, marginata and G. skottsbergii are studied for the first time using scanning electron microscopy. G. baieraeformis banaticus subsp. nov. is an Indo-European member of the Dictyophyllum-Clathropteris Flora. G. marginata banatica subsp. nov. is characteristic of the Clathropteris meniscioides Biozone (Hettangian-Sinemurian) of the European Province. G. polymorpha is of western origin, later spreading out into Siberia. G. skottsbergii europeica subsp. nov. possibly belongs to the Dictyophyllum-Clathropteris Flora that originated in the Late Triassic in eastern South-east Asia, spread to Europe in the Early Jurassic and to South America in the Mid Jurassic, where it persisted until the Early Cretaceous.
