Taxonomy
Pseudotemperoceras was named by Schastlivtseva (1986) and is listed in the Orthocerida in Sepkoski (2002)
Morphology
Pseudotemperoceras has a slender, orthoconic shell that resembles that of the earlier, Paleozoic, Temperoceras from which it gets its name, although Temperoceras is a geisonoceratid rather than an orthoceratid
Fossil distribution
So far Pseudotemperoceras is known only from the western Verkhoyansk Range, Kharaulakhsk Mountains, in the Russian state of Yakutia in eastern Siberia, where it is associated with species of Trematoceras.
