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.[1]
Discovery and name
The holotype fossil of Yarnemia was found from the Ustʹ Pinega Formation between 1976 and 1978, and described in 1984.[2]
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.[2]
Description
Yarnemia ascidiformis is a possible tunicate, growing up to Template:Cvt in length, with the standard oblong body and two openings, or siphons, on the top of the body to allow water to flow through them.
