Euspira jhuraensis

Gastropoda - Naticidae

Discussion

Perrilliat et al. (2000) reported Euspira rectilabrum (Conrad, 1858) from the Lower Maastrichtian of the Mexcala Formation, southern Mexico (p. 14, fig. 6.9, 6.10). Both species have similar shell shape and less-impressed sutures. Euspira rectilabrum, however, has a small-sized and moderately thickened shell and large number of whorls, which the present species lacks. Perrilliat et al. (2000) also mentioned that E. rectilabrum has a subovate aperture and prosocline growth lines, whereas a perfectly ear-shaped aperture and orthocline growth lines are present in E. jhuraensis. In the case of E. rectilabrum, the presence of thick callus on the parietal lip produces a narrow umbilicus, whereas E. jhuraensis is characteristically moderately umbilicate with the parietal callus having a variable thickness.

Taxonomy
Euspira jhuraensis was named by Das et al. (2019) [Etymology.—The species name refers to Jhura village of Kutch, western India, from where the species comes.]. Its type specimen is Holotype (ISI/g/Jur/N 77) and 21 paratype specimens (ISI/g/Jur/N 78-98). and is a 3D body fossil.
