摘要
Six new dinoflagellate cyst species are described from a high-resolution palynological study of the Volgian (Upper Jurassic) to Valanginian (Lower Cretaceous) sequences at the Gorodische and Kashpir sections in the Volga Basin, Russia. The following taxa are described: Aprobolocysta pustulosa sp. nov., Cyclonephelium? bulbosum sp. nov., Meiourogonyaulax distincta sp. nov., Cribroperidinium magnificum sp. nov., Cribroperidinium undoryensis sp. nov., and Thalassiphora? robusta sp. nov. These new dinocyst species are stratigraphically restricted and may prove to be useful taxa for regional biostratigraphic correlation. (C) 2003 Elsevier B.V. All rights reserved.
