Pseudotitanoceras Shimansky 1965

Genus Pseudotitanoceras Shimansky, 1965 Type species Nautilus armeniacus Abich, 1878; original designation. Included species Nautilus armeniacus Abich, 1878, Wuchiapingian, Azerbaijan. Remarks The type species of the genus is rather poorly known. Although there has been a brief revision by Shimansky (1965b) on the basis of new material, there is still no clear differentiation from other species. Shimansky (1965b) discussed the variation in the sculpture of his specimens; however, this may be due to the possibility that he also included specimens of the new genus A to be described by Korn & Hairapetian (in press).
