Pebble
A pebble is a clast of rock with a particle size of 4–64 mm (0.16–2.52 in) based on the Udden-Wentworth scale of sedimentology. Pebbles are generally considered larger than granules and smaller than cobbles. Pebble tools are among the earliest known man-made artifacts, dating from the Palaeolithic period of human history.
