Nevertheless, all living sponge classes (Demospongia, Calcarea, and Hexactinellida) are known from Cambrian age rocks, and are therefore long-ranging, successful groups despite their anatomical simplicity. Modern Sponges: A1: Recent demosponge. The ancient sponge appeared about 2.5 billion years ago—the first animal. Coming in many sizes and shapes, sponge bodies are a loose assemblage of cells held together by a special protein called collagen which is present in all animals.

They represent a continuous chemical fossil record of demosponges through the end of the Neoproterozoic. However, it is curious that unequivocal sponge fossils are generally absent in the Ediacaran (Sperling et al. 2010; Antcliffe et al. 2014). Ediacaran body fossils may contain early representatives of metazoans. However, they generally lack diagnostic features of metazoans and thus are difficulty to link to Cambrian faunas or living phyla.Genuine Sponge Fossil Coral Pendant - One of a Kind Sterling Silver Gemstone Jewelry - Mineral Crystal Collector Item.
