Description
Summary:Uralella ? cf. janimaniensis Makridin, 1964 Fig. 10.1–10.8 1964 cf. Uralella jani -maniensis new species—Makridin, p. 258, text-figs. 87, 88, pl. XIX, fig. 2, pl. XX, fig. 1. Material and occurrence. Seep 3 (PMO 224.916?, PMO 224.921, PMO 224.928, PMO 224.938–939?, PMO 224.941, PMO 224.944). Discussion. Specimens have a rounded quadrate outline and inflated profile that is suggestive of Uralella Makridin. The outline of the specimens compare to that of U . janimaniensis Makridin and U . strogonofi (d’Orbigny) in Makridin (1964, given as strogonowii , p. 254 and in text and plate captions; strogonovii in table 3). The rounder hinge line of the latter may help to differentiate these two forms. The outline is also reminiscent of specimens referred to Rouillieria aff. ovoides herein. Makridin (1964) recorded Uralella janimaniensis from the Upper Volgian. Uralella strogonofi was recorded from the Lower Volgian (Dagys 1968). A single incomplete specimen that has a highly inflated profile is suggestive of Uralella . This specimen is tentatively referred to Uralella sp., specimen number PMO 224.943, from seep 3, Upper Volgian. Stratigraphic and geographic distribution.
