Paleozoic sponges show many of the classic evolutionary patterns documented in other fossil groups, even though the sponge record is limited (Fig. 1). For example, shifts from thin-walled to thick-walled skeletons show well in both calcareous Heteractinida and in siliceous Demospongea.

Benton Quarry in Benton County was the most productive locality for fossil sponges. The new demosponge genera and species Ginkgospongia foliata and Coniculospongia radiata occur with the new species Haplistion lobatum and skeletal mats of fine spicules, along with moderately rare specimens of Hindia sphaeroidalis Duncan.

The fossil record of unambiguously identified Calcarea is relatively poor and fragmented. Most calcareous sponges in the fossil record were classified as either stromatoporoids, chaetetids, archaeocyaths, inozoans, pharetronids, or sphinctozoans. They are common in the Paleozoic and Mesozoic, however, rare in the Cenozoic.Fossil sponges are not always easy to classify with respect to Recent taxa, with some fossilised groups such as the ‘lithistids’ and ‘sphincto-zoans’ distributed within a Recent classification, but with others treated independently.

Sponges Living attached to the sea floor, sponges are a colony of single-celled animals that act like a multi-cellular animal. Each individual animal has a specific job, from filtering water for food to protection. Fossil sponges exist because of a unique skeletal structure.
