Pterygotid euryterid chelicera from the lower devonian of Victoria

A single eurypterid (Arthropoda: Chelicerata) chelicera, assigned to Acutiramus sp. cf. A. bohemicus, is described from the Wilson Creek Shale, Turtons Creek inlier, north of Foster, Victoria, Australia. The specimen comprises the proximal portion of both rami. This pterygotid chelicera supports an Early Devonian (?Lochkovian) age for the stratum at this locality, by comparison with occurrences of A. bohemicus from the Czech Republic and closely related species in northern Gondwana
