Tawuia is a millimetric disc or sausage-shaped, most likely multicellular (although coenocytic) macrofossil from the Proterozoic. Stratigraphically, they range from 1,630 million years ago[2] to the early Cambrian.[3]
The fossils are often preserved as organic compressions. They are sometimes considered to represent microbial structures;[4] some authors affiliate them with slime molds.[4] However, Tawuia is instead likely an alga,[1] as sub-cellular structures supporting this have been preserved.[5]
