Vaveliksia

Vaveliksia is an extinct genus of Ediacaran Sponge-like organism with a long, tubular-shaped body and a attachment disk similar to that of Petalonamids.

[1] The two species vary in appearance to one another, with V. velikanovi having a more tubular-shaped, sack-like morphology with a crown of wrinkles on top of one of its ends as well as possessing a much more disk-like holdfast[2] with V. vana having an appearance more similar to that of a Poriferan, with V. vana having a much more dome-shaped holdfast and a capsule-like body with no crown of wrinkles unlike V.

[1] There is single reference to V. vana from the Ediacaran deposites in the South Australia, but photographs or description of these fossils were not presented.

[4] The typical Vaveliksia had a frankfurter-like appearance, with one end attached to the substrate by a disk-like holdfast.

V. vana, found at the White Sea shores and in Australia, is thinner in diameter, has an unwrinkled top, and the holdfast is much more convex or dome-like.
