Aboriginal artefacts on the continental shelf reveal ancient drowned cultural landscapes in northwest Australia
Fig 10
Artefacts recovered under water from Cape Bruguieres (A20, A23, A29 and A11) have well-preserved, acute edges showing no signs of rolling.
This is in contrast to material where clear repeated transport and motion has resulted in rolled edges and a lack of marine growth, demonstrated by a possible (but inconclusive) artefact from Goodwyn Island cave (GC01).
