Abstract

We describe a new species of chondrophorine hydrozoan,Palaelophacmaea valentinei sp. nov., from the early Middle Cambrian part of the Cadiz Formation of the Marble Mountains of southeastern California. This find extends the stratigraphic range of this genus into the early Middle Cambrian and its geographic range into the western United States. We review various chondrophorine-like fossils and present a tentative chondrophorine phylogeny in light of this find.

Kurzfassung

Eine neue Chondrophoroidea (Cnidaria, Hydrozoa),Palaelophacmaea valentinei n. sp., wird aus der mittelkambrischen Cadiz-Formation des Marble Gebirges von Kalifornien beschrieben. Dieser Fund dehnt die stratigraphische Reichweite des GenusPalaelophacmaea bis ins frühe Mittel-Kambrium aus und ist bislang der erste aus den westlichen Vereinigten Staaten. Phylogenetische Entwicklungslinien werden anhand einer Übersicht fossiler chondrophoriner Hydrozoen diskutiert.
