This archaeological study identified specialized stone tools (anvils) used by Aboriginal Australians specifically for cracking quandong nuts, analyzing 1,327 ground stone implements across 12 locations in the Murray Darling Basin. While quandong kernels have been traditionally used in skin care preparations, this research is about the *tools* used to process the nuts—not about the ingredient's skin benefits themselves.

Researchers examined 1,327 ancient ground stone implements from museum collections across 12 sites in the Murray Darling Basin, identified which ones were likely quandong-cracking tools based on their distinctive shape and pit patterns, then analyzed 6 of them for wear marks and residue to confirm their specific use.
