Tawuia

Tawuia is a millimetric disc-shaped, most likely multicellular macrofossil from the Neoproterozoic. It is considered to be synonymous with Chuaria and Longfengshania, which, in turn, are thought to represent different life stages of the same organism.
"Tawuia" describes a more sausage- or crescent-shaped fossil; "Chuaria" refers to more discoial instances.
The fossils are often preserved as organic compressions. They are considered to represent microbial structures; some authors consider them to be affiliated with slime molds
Stratigraphically, they range from to the late Ediacaran.
"Chuaria" is multicellular.
