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] It was from shale in the Dabis Formation in Namibia dated from 549 to 543 mya.[5] The name has also been misspelled as Ernettia in some papers. Other names that have been given to fossils that are probably the same organism are: Erniaster, Erniobaris, Erniobeta, Erniocarpus, Erniocentris, Erniocoris, Erniodiscus, Erniofossa, Erniograndis, Ernionorma, Erniopelta and Erniotaxis.[6]
