Abstract: Pseudotitanoceras armeniacum (Abich, 1878) Nautilus armeniacus Abich, 1878: 24, pl. 2 fig. 5. Pseudotitanoceras armeniacum – Shimansky 1965b: 162, pl. 16 figs 5–6. Type material Holotype AZERBAIJAN • Dorasham 1; Araxoceras Beds (early Wuchiapingian); illustrated by Abich (1878: pl. 2 fig. 5); LGI 14/99. Remarks “ Nautilus armeniacus, nov. form.” was described and illustrated by Abich (1878: pl. 2 fig. 5). It is a phragmocone fragment with a whorl height of about 38 mm. It is deformed but shows some features of the conch shape and sculpture. According to Abich’s description, the flanks are slightly concave and the venter is more clearly concave; they are separated by a narrowly rounded ventrolateral shoulder. The ventrolateral shoulder bears closely spaced nodes, which have the same width as the interspaces and also correspond approximately to the distances between the septa. The suture line shows broadly rounded lobes on the flanks and venter.
