Tawuia

Tawuia
Scientific classification
Domain:	Incertae sedis
Genus:	Tawuia

Tawuia is a millimetric disc-shaped macrofossil from the Neoproterozoic. It is considered to be synonymous with Chuaria and Longfengshania.^[1]

Tawuia describes a more sausage- or smile-shaped fossil; Chuaria refers to more discoial instances.

The fossils are often preserved as organic compressions. They are considered to represent microbial structures;^{[verification needed]} some authors consider them to be affiliated with the algae.^{[verification needed]}

Stratigraphically, they range from 1,630 million years ago^[2] to the late Ediacaran.^[3]
