Trace fossils (Pascichnia) from the Silurian of New South Wales, Australia

Grazing trails are described from Lower Silurian laminated siltstones and shales at Quidong, southern N. S. W., Upper Silurian quartz-rich greywackes (the Cookman Formation) at Cheshires Creek and uppermost Silurian greywackes at Gowan Green in central-western N. S. W. The trace fossils Paleodictyon and ?Gordia occur at Quidong, a larger variety of Paleodictyon, Granularia and an unnamed branching track at Cheshires Creek, and Cosmorhaphe at Gowan Green. The nature of preservation and the environmental significance of the traces are discussed. Comments on the possible origin of Paleodictyon are also presented.
