| Abstract |
The new hexactinellid brachiosponge Toomeyospongia apachensis is described from the Lamar Limestone, of upper Guadalupian age, from the Seven Heart Gap area in the Apache Mountains, at the southwestern margin of the Delaware Basin in western Texas. The sponge is a massive, subhemispherical form with a strong "armored" dermal layer of large pentacts and stauracts, with an interior skeleton of irregulatly oriented and variously sized hexactines and less common derivatives. Interior skeleton is perforated by large radiating canals and smaller interconnecting canal series. The genus is another of the specialized hexactinellid sponges that characterize Permian faunas in North America. |
