Petrographic study of enigmatic organic structures resembling sponges collected from Waulsortian buildups (and not in the lateral equivalent or cover facies) on wave-polished surfaces on the coast of Co. Kerry, southwest Ireland, shows that they are indeed sponges or sponge-derived. This is the first record of sponge body fossils from undoubted Waulsortian facies where sponge remains in the form of scattered spicules or spicule bundles are known to be sometimes common. The sponges are varied in shape and size and a Iso in their state of fragmentation and preservation. The present study reviews their macroscopic and microscopic features. Some of the primary and early-diagenetic textures that can readily be attributed to sponges are presented. The distribution of those fossils within the Waulsortian in the Co. Kerry outcrops is discussed as is the reason for their apparent concentration in this area as compared with Waulsortian buildups elsewhere.
