Physalocysta quadrata

quadrata Xu Jinli et al., 1997, p.122–123, pl.23, figs.3–4,7–8 ex He Chengquan et al., 2009, p.360,660.  Holotype: Xu Jinli et al., 1997, pl.23, fig.3.  This name was not validly published in Xu Jinli et al. (1997), since no English or Latin description was provided; He Chengquan et al. (2009, p.660) validated the name by publishing an English diagnosis.  Age: middle-late Eocene.
