The decision to collect the stromatolites was a difficult one because it is important to study fossils of this nature in their context. The large slab measuring about 1.25 m x 0.75 m containing conical stromatolites was collected at the end of the excursion, and has now been reassembled for display in the Western Australian Museum. Natural weathering processes, and the possibility of flooding of the nearby river system during the cyclone season, were factors in the decision to remove and preserve the fossils. Some deterioration had already been noted over the past two years. To try to prevent localities being plundered, precise site locations have not been published.
Some localities are registered reserves and permission is required for collecting.
No fossils can be exported from Australia without the relevant customs permits. For further information contact either GSWA or the Western Australian Museum . Close up of the 'egg-carton' cones during preparation for removal.
