Specimen identification is the backbone of archeozoological research. The challenge of differentiating postcranial skeletal elements of closely related wild animals in biodiverse regions can prove a barrier to understanding past human foraging behaviours. Morphometrics are increasingly being employed to classify paleozoological animal remains, however, the potential of these methods to discriminate between wild animal groups has yet to be fully realised. Here we demonstrate the applicability of a traditional morphometric approach to taxonomically classify foot and ankle bones of kangaroos, a large and highly diverse marsupial family. Using multiple discriminant analysis, we classify archaeological specimens from Boodie Cave, in northwest Australia and identify the presence of two locally extinct macropod species during the terminal Pleistocene. The appearance of the banded hare-wallaby and northern nail-tail wallaby in the Pilbara region at this time provides independent evidence of the ecological and human responses to a changing climate at the end of the last Ice Age. Traditional morphometrics provides an accessible, inexpensive, and non-destructive tool for paleozoological specimen classification and has substantial potential for applications to other diverse wild faunas.

There are few archaeological sites that contain records for Pleistocene coastal occupation in Australia, as is the case globally. Two major viewpoints seek to explain why so few sites exist. The first is that the Pleistocene coast was a relatively marginal environment where fluctuating sea levels actively inhibited coastal resource productivity until the mid-to-late Holocene. The second position suggests that the Pleistocene coast (and its resources) was variably productive, potentially hosting extensive populations, but that the archaeological evidence for this occupation has been submerged by sea level rise. To help reconcile these perspectives in Australia, this paper provides a review, discussion, and assessment of the evidence for Australian Pleistocene coastal productivity and occupation. In doing so, we find no reason to categorically assume that coastal landscapes were ever unproductive or unoccupied. We demonstrate that the majority of Pleistocene coastal archaeology will be drowned where dense marine faunal assemblages should only be expected close to palaeo-shorelines. Mixed terrestrial and marine assemblages are likely to occur at sites located >2 km from Pleistocene shorelines. Ultimately, the discussions and arguments put forward in this paper provide a basic framework, and a different set of environmental expectations, within which to assess the results of independent coastal research. • Addresses Pleistocene coastal occupation and productivity in Australia. • Australian Pleistocene coasts were likely widely occupied and variably productive. • A basic framework within which to assess coastal occupation patterns is provided.
