Sponge

Cobscar Spoil Heaps

Sponge. Possibly Hyalostelia. Sponges are simple, multicellular animals. Larvae are motile, but adults remain fixed to a substrate. They feed mainly on bacteria and other micro-organisms. They are believed to be at the base of the evolutionary tree for multicellular animals. As fossils, they pre-date the Cambrian Period. Those at Redmire are found in Carboniferous limestone and were, therefore, tropical.
