Tawuia
Temporal range: Statherian to Cambrian Stage 3, 1630–518 Ma
Fossil specimen, Geological Museum of China
Scientific classification Edit this classification
Domain: Eukaryota
Clade: incertae sedis
Genus: †Tawuia
H.J.Hofmann, 1979 [1]
Type species
Tawuia dalensis
Hofmann 1979
Species
  • Tawuia dalensis
  • Tawuia robusta
  • Tawuia sinensis [1]

The fossils are often preserved as organic compressions. They are sometimes considered to represent microbial structures;[2] some authors affiliate them with slime molds.[2] However, Tawuia is instead likely an alga,[1] as sub-cellular structures supporting this have been preserved.[3]
