Corumbella
Corumbella
Extinct genus of Ediacaran animals
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]
