The Ediacaran biota (flourished 579-541 Mya) forms an important and unresolved episode in the history of life. These organisms arose soon after the end of the major glaciations of the Cryogenian, and persisted until the beginning of the Cambrian.

They are thought to include some of the earliest animals. Understanding the nature and lifestyle of the Ediacaran organisms is therefore important in tracing the potentially long fuse of the Cambrian explosion.

Yet they remain puzzling. This project will use micro-CT to investigate two particularly contentious structures found in rocks of this age, and assess how they fit into the larger picture of the origin of multicellular animals in this age.
