Abstract
Representatives of ginkgoaleans from the Middle Jurassic of the Stoilensky opencast mine in the Belgorod Region and the Mikhailovsky opencast mine in the Kursk Region, European Russia are described for the first time. Remains of ginkgoaceous affinity dominate in some samples and are represented by leaf fragments of Sphenobaiera angrenica (Samylina) Nosova, originally described from the Middle Jurassic Angren Formation in Uzbekistan where they are associated with female reproductive structures (collar complexes) of Nagrenia samylinae Nosova. Rare fragments of the collars were also found in the Stoilensky mine. These remains are assigned to Nagrenia sp. As well as in the Angren Formation, seeds of Allicospermum budantsevii Gordenko are recorded in the Stoilensky mine.
期刊介绍：
The Review of Palaeobotany and Palynology is an international journal for articles in all fields of palaeobotany and palynology dealing with all groups, ranging from marine palynomorphs to higher land plants. Original contributions and comprehensive review papers should appeal to an international audience. Typical topics include but are not restricted to systematics, evolution, palaeobiology, palaeoecology, biostratigraphy, biochronology, palaeoclimatology, paleogeography, taphonomy, palaeoenvironmental reconstructions, vegetation history, and practical applications of palaeobotany and palynology, e.g. in coal and petroleum geology and archaeology. The journal especially encourages the publication of articles in which palaeobotany and palynology are applied for solving fundamental geological and biological problems as well as innovative and interdisciplinary approaches.
