These Kimberley points were collected in the Kimberley
Plateau region in northwestern Australia in 1910. They are
all bifacially flaked. The edges are serrated and they have
very sharp needle-like points. They are made of
chalcedony, glass and quartzite. They range in size from
1 3/8 inches (3.4 cm) long to 2 3/16 inches (5.5 cm) long.
