Naticopsis cf. heshanensis Pan & Erwin, 2002
( Fig. 20 View FIGURE 20 K–L)
cf. Naticopsis (Naticopsis) heshanensis Pan & Erwin, 2002: 21 , fig. 11.12–11.17.
Material. One specimen: ESKU-19- LP 44.
Dimensions (mm): ESKU-19- LP 44: height = 19.0; width = 16.2; apical angle = 124 º.
Description. Subglobose shell, very low-spired, medium-sized, comprising c. 3.5 whorls; apex obtuse; whorls rapidly increasing; body-whorl large and inflated, with flatly convex periphery; whorls embracing on preceding whorl, well above periphery; whorl surface with numerous fine, prosocyrt, distinct growth lines; suture adpressed; base convex; aperture unknown.
Remarks. This single globose shell with distinct, dense growth-lines resembles Naticopsis (Naticopsis) heshanensis Pan & Erwin, 2002 (p. 21, fig. 11.12–11.17) as reported from the Permian of Guangxi Provinces, South China, although the present specimen has a much lower spire than the holotype of N. (N.) heshanensis . The Permian species N. permica Netchaev, 1894 as illustrated by Mazaev (2015, p. 959, pl. 33, figs 1–5) from the Middle Permian of Volga Region, Russia is similar but has a higher spire, more convex whorls and less distinct growth lines.
