Where: Queensland, Australia (18.8° S, 144.9° E: paleocoordinates 18.8° S, 144.8° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Wyandotte Formation, Late/Upper Pleistocene (0.1 - 0.0 Ma)

• The base of the Wyandotte Formation is beyond the conventional 14C range (>45000 ybp). It is inferred to postdate a 410 ka basalt flow. The rate of downcutting to form the valley is not known, but since 410,000 ybp a substantial valley has been cut. Between 4 to 10 metres of Unit A were deposited prior to unit B, which has a basal date of 30,400 ybp (+750/-700 yrs). It is reasonable to suppose that the erosive phase might easily have taken half of the available interval, a corollary of which is that the base of the Wyandotte Formation may not be much older than 200,000 ybp. The duration of the hiatus between final deposition of Unit A and the onset of Unit B is unknown.
