The genus Wewokella (Porifera) in the Pennsylvanian of Ohio
R. D. Hoare, and M. T. Sturgeon
Specimens of the sponge Wewokella solida Girty are reported from the upper Pottsville and lower Allegheny Groups in Ohio. Spicules of all specimens are composed of calcium carbonate. Conditions of high pH and(or) high temperature may have resulted in silica-carbonate replacement if the spicules were originally opaline silica. Marginally favorable habitats may have been present in Pennsylvanian epicontinental seas for representatives of the Hyalospongea. Specimens show evidence of strong current action and may have lived on a muddy bottom.
