A variety of Small shelly fossil forms. From Basic Palaeontology . Benton M.J. & Harper D. 1997.
The SSF assemblages consist of tiny plates, cones and tubes made from various minerals. Some elements are considered to be the sclerites of larger animals, multiplated worms possibly, others seem to be the tiny shells of individual animals. Many components of the small shelly fauna cannot be allied with any modern group, and like the Ediacara, could represent anatomies that arose early and disappeared quickly.
