Corumbella is an extinct genus of terminal-Ediacaran animals. It is the only genus in the monotypic family Corumbellidae, and is represented by a single species Corumbella werneri. ^[2] It possessed a carapace made up of thick polygonal rings ^[3] in which plates with pores and papillae ^[4] attest to the advent of skeletogenesis in the latest Neoproterozoic metazoan. ^{[3] [4]} It was sessile and somewhat resembles the later conulariids, ^{[3] [5]} though this similarity is likely superficial; its secretion of an aragonitic scleritome suggests a Eumetazoan affinity. ^[6]
