Ernietta plateauensis, the sole species of the genus Ernietta,[2] is a bag-shaped erniettomorph genus that lived half-buried in sediment,[3] and probably fed by osmosis.[4] It had chambered walls.[5]

Distribution and species

Its fossils has been found in sandstones of the Kanies and Kliphoek Members of the Dabis Formation, Namibia. These deposits have been dated at over 548 Ma.

The name has also been misspelled as Ernettia in some papers. Many species are now recognized as junior synonyms of Ernietta plateauensis, including:[2]
