Detail of the weathered surface of a fusulinid limestone from the Upper Upper Carboniferous of Elk County, Kansas , USA (length of the lower edge of the picture approx. 4 cm)

The types of order form housings made of extremely fine-grained calcite, with tightly packed crystals of the same dimensions , only a few micrometers in size. More developed forms had walls made up of several layers.
