Abstract
A diverse assemblage of Middle Cambrian sponges, recently collected from the Wheeler and Marjum Formations of western Millard County, Utah, includes a variety of demosponges and hexactinellids. This collection includes the verongiidVauxia bellulaWalcott, 1920, and the protomonaxonidsChoia carteriandChoia ridleyiWalcott, 1920,Hamptonia bowerbankiWalcott, 1920, andHamptonia parvan. sp. Hexactinellids in the collection include the reticulosid protospongioidsDiagoniella hindeiWalcott, 1920, andDiagoniella magnan. sp.; the dierespongioid hydnodictyidValospongia?gigantusRigby, 1973; and the hintzespongioidHintzespongia bilaminaRigby and Gutschick, 1976. A specimen of the problematicSentinelia?dracoWalcott, 1920, is also documented as part of the collection.Keywords
