1 Introduction. Sponges are well known from present-day hydrothermal communities and cold seeps, and most of them are background organisms that may occur elsewhere. Only a few are proven to be dependent on chemosynthesis. On the other hand, sponges are only rarely reported and very poorly known from fossil hydrothermal vent and cold seep deposits.
Common Fossils of Kansas--Sponges. Heliospongia is a sponge although not bearing much resembleance to what most people them of when the word sponge is mentioned.
