The "Adelaide point" is found in Australia. Its construction, based on truncations on a blade, has a nearly trapezoidal form. The Adelaide point emphasizes the range of variation in both time and culture of the laminar microliths; it also shows their technological differences, but sometimes morphological similarities, with geometric microliths. Laminar microliths can also sometimes be described as trapezoidal, triangular or lunate. However, as we will see below, they are distinct from the geometric microliths because of the strokes used in the manufacture of geometric microliths, which mainly involved the microburin technique.
