Parvancorina

Parvancorina is a genus of shield-shaped bilaterally symmetrical fossil animal that lived in the late Ediacaran seafloor. It has some similarities with the Cambrian trilobite-like arthropods.

Etymology
The generic name is derived from a crasis compound word from the Latin parva ancora (small anchor).

The specific name of the type species, P. minchami, honors Mr. H. Mincham, the private collector, who in 1957 had collected and presented a number of fine specimens of Ediacaran fossils to the South Australian Museum.

The specific name of P. sagitta from the Latin sagitta (arrow).

Occurrence
P. minchami fossils were first discovered in the Ediacara Member of the Rawnslay Quartzite, Flinders Ranges in South Australia.[1] This species also known from deposites of the Verkhovka, Zimnegory and Yorga Formations in the White Sea area of the Arkhangelsk Region, Russia. Additionally, similar poorly preserved Parvancorina sp. fossils were found in Lyamtsa Formation of this Russian region.[2]

P. sagitta is found in the Verkhovka formation on the Solza River, White Sea area of the Arkhangelsk Region, Russia.
