Abstract

The Early Cretaceous sediments widely distributed in the central Jilin and northern Liaoning of Northeast China called as Shahezi Formation contain Ruffordia-Onychiopsis flora. About 100 species belonging to 50 genera are described from these strata. In this article, the authors restudied the flora and described 7 new species- fungi: unnamed fungus, Microthyricites shaheziensis sp. nov.; ferns: Atbyrium dentosum (sp. nov.); Bennettitales: Nilssonipteris latifolia (sp. nov.) N. introvenius (sp. nov.), Nilssoniopteris sp. nov.?; Ginkgoales: Sphenobaiera szeiana (sp. nov.). Juding from the composition and characteristics of the flora, it has been considered that it may belong to the Sibirian-Canadian province phytogeographically. The age of the flora should be considered as Early Cretaceous.
