Type locality: Henk's Hollow Local Fauna, Tertiary System C, approximately 3.6 km southwest of Tedford's (1967) Site B, Riversleigh, northwestern Queensland, Australia. Late Oligocene - early middle Miocene ( Scanlon 2001 ). Remarks: Smith and Plane (1985) described the two extinct species riversleighensis and antiquus from Australia. Kluge (1993) synonymized antiqua (name amended for gender by Scanlon 1992 ) with olivaceus Gray due to the lack of auta pomorphies and great overall similarity and riversleighensis with spilota Lacepede . Scanlon (2001) synonymized antiqua with riversleighensis.
