Proterosuchid archosaur remains from the Early Triassic Bulgo Sandstone of Long Reef,New South Wales

Two associated anterior dorsal vertebrae of a primitive archosaur are described from the Early Triassic (Dienerian–Spathian) Bulgo Sandstone at Long Reef, New South Wales, Australia. Character states including anteroposteriorly elongate centra, dorsal neural spines with height greater than length, the possible presence of intercentra, double-headed rib articulations and well-developed apical tables on the neural spines suggest affinity with proterosuchid archosauriforms and permit some comparisons with previously described Australian taxa. The Bulgo Sandstone vertebrae represent the first record of archosaurian body fossils from the Sydney Basin and are one of only a handful of occurrences thus far documented from the Triassic of Australia.
