Sphaerospongia is an extinct genus of organism found in marine beds of Devonian age. Its classification is enigmatic, but it is typically placed among the sponges[2] or the receptaculites.[3] The organism has a surface covered with hexagonal plates, and some early taxonomists placed it among the echinoderms.[4] It is found in close association with the horn coral Tabulophyllum traversensis in the Onate Formation of New Mexico, US, where it provides a substrate for the coral.[5]
