Octomedusa is a genus of extinct scyphozoan jellyfish known from the Late Carboniferous sediments of the Mazon Creek fossil beds. It contains a single species, O. pieckorum. It was first described by Gordon Johnson and Eugene S. Richardson, Jr. in 1968, where its holotype (FMNH no. PE 11410) and paratype (FMNHno.PE 11377) being unearthed by Mr. and Mrs. Ted Piecko.[1] Fossils of the jellyfish occur and other organisms occur in iron-stone concentrations. Octomedusa was described by Foster (1979) as representing a primitive coronate, however these affinities have been challenged and Octomedusa has had many more affinities after.[2][3] O. pieckorum is the type species of the genus Octomedusa[4] [5]
