Staurinidia is a genus of Ediacaran soft-bodied organism from the deposits of the Ust' Pinega Formation. It is a monotypic genus, containing only the single species Staurinidia crucicula.[1] The genus was first described in 1985 by Russian palaeontologist Mikhail A. Fedonkin. S. crucicula's four-fold symmetry is present as a result of four canals radiating from the middle of a small cavity in the middle of the body.[1] Other forms with four way symmetry, mainly medusoid forms, from the Ediacaran (Conomedusites, Persimedusites) comprise an essential chunk of the Ediacaran diversity of symmetry; their organisations are similar to, though smaller than, those of a modern-day scyphozoan cnidarian.[2]
