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
[edit]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.
