When: Holocene (0.0 - 0.0 Ma)

• Recent stratigraphic studies, supported by a large number of radiocarbon dates on bird bones, demonstrate that much of this so-called midden material has been eroded from naturally accumulated deposits that considerably predate human occupation by hundreds to thousands of years. An example is the abundant material from Sutton's main Waihora site (see Sutton, 1976, 1979, 1981, 1982; Marshall et al., 1987), which, apparently, was obtained by excavation of intact strata and was assumed to be entirely of midden origin, but which has yielded dates of ca. 5750 and ca. 5950 CAL BP (for Dieffenbach's Rail bones from Sutton's Layers I (NZA 3193) and III (NZA 3194), respectively; see Appendix, locality 1).
