Chaetetids, extinct demosponges, were common frame-builders in small reef mounds during the Middle Carboniferous. Chaetetids from the Coal City Limestone Member (Pawnee Limestone, Middle Pennsylvanian) in Appanoose County, Iowa, contain the remains of a cryptic community attached to the undersurfaces of the colonies. Identified coelobites include the attached brachiopods Cooperina sp., Teguliferina sp., Heteralosia sp., and Composita sp.; the encrusting bryozoans Fistulipora sp. and Metelipora sp.; the holdfasts of fenestrate/ramose bryozoans; the worm Spirorbis sp.; the rugose coral Lophophyllidium sp.; the foraminiferid Tetrataxis; and the boring traces Caulostrepsis and Rogerella/Zapfella. Small echinoid plates and spines are associated with some of these cavities suggesting that they may have also lived there. Cross-cutting relationships reveal no clear pattern of encrustation by these cryptic dwellers.
