Zheng Shao-lin, Zhang Wu and Zhang Ying
A new species of Genus Nilssoniopteris, N. hailarensis sp. nov. is described from the core of bore hole of the auxiliary well (No. 5) in Hailar Basin, China (47˚58′N. Lat., 117˚10′E. Long.). These specimens were collected in sediments of the Lower Cretaceous Yimin Formation. This new species is characterized by long-linear, entire, narrow leaves. Their shapes and nervations show Taeniopteroid-type with a Bennettitalean cuticle. Lamina attached late rally to upper surface of midrib. Midrib up to 3 cm wide, prominent below but only about one-third of its width exposed above. The reported species rather similar to Nilssoniopteris beyrichii (Schenk) Nathorst from the Wealden Flora of W. Europe in leaf shape. N. hailarensis is distinguished from the latter by its cuticle.
