Yarnemia ascidiformis is a fossil tentatively classified as a tunicate. While Y. ascidiformis looks similar to tunicates, the oldest unequivocal tunicate, Shankouclava[1] dates to the Cambrian period, while Y. ascidiformis is Ediacaran in age.[2][3]
Etymology
The generic name Yarnemia comes from the village of Yarnema near which the first specimens were found. The specific name of the Y. ascidiformis refers to the likeness to ascidians.
