Vologdinella is a poorly known genus of Middle Cambrian fossils from a Paleozoic limestone in the Chinguiz Mountains of Kazakhstan. The genus was established by Z. G. Balashov in 1962 for a single species, Vologdinella antiqua, which was originally described and illustrated as Orthoceras? antiquus by the Russian paleontologist Aleksandr Grigoryevich Vologdin in 1931.
The genus was historically classified as a cephalopod, though it has since been removed from this group.[1][3] Vologdinella bears superficial resemblance to the Early Cambrian Volborthella, which was later included in Agmata, an extinct phylum proposed by the paleontologist and geologist Ellis L. Yochelson. Vologdinella was also considered for inclusion in the Agmata, or in questionable synonymy with Vologdinella, but a later study determined that the genus was not related to them.[4][5]
