Abstract

A new species, Oswaldheeria eximia sp. nov., was discovered in the Bathonian continental deposits of an open-cast mine of Mikhailovskii Rudnik Mines, near the town of Zheleznogorsk in the Kursk Region. This is the first record of Oswaldheeria Bose et Manum from European Russia. The leaf anatomy of Oswaldheeria, reconstructed for the first time based on material of unique preservation, has shown that members of this genus were not closely related either to the Ginkgoales or to modern Sciadopitys Siebold et Zucc.
