Archaeology Seminar Series : Further explorations of the fossiliferous chert artefact record – building the links between the West Australian and South Australian archival records |
Other events...

Eocene fossiliferous chert is a distinctive stone used in
the manufacture of stone artefacts commonly found in
archaeological sites in southwestern Western Australia
(WA). Since disputing the ‘offshore source’ theory for
this material, our research has focused on the
characterisation and sourcing of this idiosyncratic
material. These investigations include the use of nondestructive
high-resolution X-ray computer
tomographic (CT) imaging at the Australian
Synchrotron to map and identify embedded bryozoan
(and other) fossils within archival artefact samples and
potential source material from offshore drill cores in the
Perth Basin and from the Nullabor Plain to the east.
In addition, we have begun to explore the South
Australian archival records, including from key
archaeological sites including Allen’s Cave, Koonalda
Cave and Wilson’s Bluff. Preliminary analyses indicate
that both the bryozoan and foraminiferal fossil
assemblages offer a viable means to characterize and
potentially source fossiliferous chert artefacts. The
potential for long-distance exchange of fossiliferous
chert by Aboriginal people across Australia is supported by
the archival records and published documents of Bates,
Tindale and other researchers. It is argued that the Eucla
Basin was a major source for fossiliferous chert artefacts
found both east and west of Wilson’s Bluff. Further work
combining biostratigraphy and lithology with archaeology
and ethnography is needed to explore these ideas further.
