Abstract
Kinchega National Park is in a stoneless region of semi-arid Australia. Pebbles commonly encountered during an archaeological survey of this area show a close resemblance with emu gastroliths in terms of size, shape and surface characteristics. Further comparisons reveal a similarity in the surface features with gastroliths from extinct New Zealand moa. It is suggested that emus will ingest artefactual stone for use as gastroliths, especially in areas lacking natural stone. The implications of this are discussed in terms of transport of stone as well as the configuration and temporal integrity of surface stone artefact assemblages.
