Archaeology: bone tools
Habitat comments: "well-sorted sandy alluvial facies with crossbedding" that "primarily represent lateral fills along a floodplain margin and the valleys of ephemeral tributary streams"
"barbed and unbarbed bone points" were recovered but there is no mention of stone artefacts
