The stratigraphy and the Quaternary depositional history of Teapot Creek, a tributary of the MacLaughlin River in the Southern Monaro, southeastern New South Wales, are given and discussed. Other fossil-mammal bearing deposits in the MacLaughlin Valley are reported. The valley of Teapot Creek contains a sequence of terraces. The highest and oldest of these is characterised by poorly sorted conglomerate deposits typical of stream-deposited longitudinal bars. Palaeomagnetic results obtained from this terrace are interpretable to the Bruhnes normal polarity interval (<0.78 Ma). A second, lower terrace is set into the highest terrace. Deposition of this terrace began before 5320±80yr BP and is characterised by overbank deposits. The lowest and youngest terrace, consisting mostly of fine clays and silts, represents lateral accretions inside meander loops during modern flooding events. The youngest terrace contains the remains of modern introduced mammals. The intermediate terrace has yielded fossils of modern Macropus and an unidentified murid. The highest terrace contains the remains of fossil mammals found in Plio-Pleistocene fossil deposits elsewhere in Eastern Australia. Species identified from it are Macropus altus, M. ferragus, M. titan, Procoplodon goliah, P. pusio, Protemnodon anak, P. "roechus/brehus", Sthenurus atlas, S. occidentalis, S. newtonae, Troposodon minor, and Phascolonus gigas, but no modern species of Macropus kangaroos or wallabies. Pleistocene fossil mammals have been located in four other sites in the valley of the MacLaughlin River. A fifth site, Chalk Pool, is sedimentologically different and at a lower level relative to the modern river than the other terraces. Species identified in the Chalk Pool deposit are regarded as Plio/Pleistocene forms (Macropuspan, Protemnodon chinchillaensis and P. "roechus/P. brehus"); of these, P. chinchillaensis is known only from the Pliocene.
