a tiny stone tool, characteristic of the Mesolithic period, many of which were probably used as barbs.
( Gr. 'micro'=small + 'lithos'=stone) A very small flint tool used as barbs and tips of arrows.
Small (1-3 cm long) stone tools with evidence of retouch. Includes 'Bondi Points' segment, scrapers, backed blades, triangle and trapezoid.
A small stone tool, usually made of flint or chert, consisting of a segment of blade blunted on one or both sides and hafted into an arrow shaft or handle as a projectile or other tool. The first half of the Mesolithic is characterised by larger and more robust microliths. These become smaller and more geometric in shape later in the period. The very late Mesolithic has exceptionally small microliths known as microlithic rods.

Microliths are very small stone tools. They seem to have been used together to form a multi-part tool with lots of cutting edges.
A microlith is a small stone tool, typically knapped of flint or chert, usually about three centimetres long or less. Microliths were either produced from small blades (microblades) or made by snapping normal big blades in a controlled manner, which leaves a very typical piece of waste (microburin). The latter type of microliths are called geometric microliths.
