Pomoria rhomboidalis is a Late Ediacaran microfossils of cyanobacterial trichome which is a characteristic taxon of the fossil microbiota in the East European Platform, it is also found in the Siberia and China.[1][2][3] It is the only species in the genus Pomoria.[2]
Originally, this fossil was described as Oscillatoriopsis rhomboidalis Sivertzeva, 1985 on the basis of a specimens from Torozhma borehole, Arkhangelsk Region, Russia.[1][4] Later, the species O. rhomboidalis was reassigned to the separate genus Pomoria Sivertzeva et Jankauskas, 1989.[2]
Pomoria is distinguished from other fossil trichomes by a thin longitudinal or diagonal striate sculpture.[2][3]
