Cochleatina

Cochleatina is an organic-walled microfossil ('Small Carbonaceous Fossil') known from the late Ediacaran period and early Cambrian Fortunian Stage.^[1] Cochleatina comprises a complex spiral ribbon structure, with a serrated outer margin. These spirals are frequently found embedded in an organic sheet.^[1][2][3] Cochleatina is a rare example of a fossil taxon known to span the Ediacaran–Cambrian boundary.^[1]
