Cordosphaeridium mirabile
Cordosphaeridium mirabile He Chengquan, 1991
Holotype: He Chengquan, 1991, pl.15, fig.7; text-fig.34.
Age: Paleocene-Middle Eocene
Description from He Chengquan, 1991, translated by Suning Hou, 07-01-2019
Description: Oval body. Wall thickness about 3.5μm, inner wall thick, slightly rough; Outer wall thin, the surface fibrous or fibrous-short wrinkle-like. The processes are formed by the fibrous outer wall, the vast majority look like bean sprouts (tauge), 20-25μm long, width varies, hollow (?), Distally closed, there is a ball or bean shape thickening matter near the end, and occasionally, the adjacent thickening matters fuse with each other; Processes flexible, strongly bent so that the distally folded up. There is no complete process visible around the body, there are as well as individual cylindrical processes (antapical process), hollow, base slightly larger,distally open, the end complete without any structure, its length about 25μm, width about 10μm. Processes intratabular, each reflecting a plate. The archeopyle outline oval, precingular, formed by the movement of the third precingular platei. Operculum preserved in situ. Body length 85μm, width 67.5μm.
Location and stratigraphy: Wuqia County Basebulak; Qimugen fm lower member (?) And Wulagen fm.
