Tirasiana is a genus of disc-shaped animals from the Ediacaran period that contains three species: T. concentralis, T. coniformis and T. disciformis, all which are distinguished by the complexity of their stepped structure.[2]
Affinity
Tirasiana moulds are thought to be discoidal body fossils of some kind, showing radial symmetry in them[3] and with a round nodule in the middle.[4]
