Binzhoudinium membranospinosum

membranospinosum Xu Jinli et al., 1997, p.53, pl.6, figs.6–7 ex He Chengquan et al. 2009, p.335–336,650.  Holotype: Xu Jinli et al., 1997, pl.6, fig.6.  This name (with the epithet mispelled as "branospinosum") was not validly published in Xu Jinli et al. (1997), since no English or Latin description was provided; He Chengquan et al. (2009, p.651) validated the name by publishing an English diagnosis.  Age: middle-late Eocene.
