Yarnemia ascidiformis is a fossil tentatively classified as a tunicate. If this classification is correct, it would significantly extend the range of the tunicate fossil record from the Cambrian back into the Ediacaran.[2]

The holotype fossil of Yarnemia was found from the Ustʹ Pinega Formation between 1976 and 1978, and described in 1984.[3]

The generic name Yarnemia comes from the village of Yarnema near which the first specimens were found. The specific epithet, ascidiformis, refers to the likeness to ascidians.[3]
