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

Its fossils has been found in sandstones of the Kanies and Kliphoek Members of the Dabis Formation, Namibia. This deposits have an age more than 548 Myr.

The name has also been misspelled as Ernettia in some papers. A total of 11 genera and 24 species have been described that are considered synonyms of the Ernietta plateauensis:[5]
