Description
Pseudogastrioceras relicuum Korn & Ghaderi in Korn et al., 2016
Fig. 16; Table 1
Pseudogastrioceras relicuum Korn & Ghaderi in Korn et al., 2016: 852, text-fig. 12.
Diagnosis
Pseudogastrioceras with moderately large conch; diameter attaining 70 mm. Conch shape thinly discoidal (ww/dm=0.40–0.45), involute (uw/dm = 0.05–0.10) with converging flanks and broadly rounded venter. Ornament with about 15 faint spiral lines on the venter.
Material examined
Holotype IRAN • East Azerbaijan, Ali Bashi N section; Paratirolites Limestone; illustrated by Korn & Ghaderi in Korn et al. (2016: text-fig. 12); MB.C.25173.
Additional material
IRAN • 2 specimens; Esfahan Province, Baghuk Mountain 1 section; Hambast Formation; MB.C.29659 to MB.C.29660 • 1 specimen; Esfahan Province, Baghuk Mountain G section; Hambast Formation; MB.C.29661 • 2 specimens; Esfahan Province, Baghuk Mountain H section; Hambast Formation; MB.C.29662 to MB.C.29663.
Description
All specimens are rather poorly preserved, but MB.C.29661 is the best of them, though somewhat deformed (Fig. 16). It is a corroded specimen with a 56 mm conch diameter, which does not allow accurate measurements of the conch.
Stratigraphic range
Paratirolites Limestone; 6.80 to 3.30 m below the extinction horizon (Dzhulfites nodosus Zone to Paratirolites lanceolobatus Zone).
