Quarry section at Latamneh, ~100km downstream of Homs, measured along the sinuous course of the river. The dark basal gravel, ~8m thick, is overlain by ~2m of silt, then ~12m thickness of paler upper gravel. Palaeolithic artefacts and mammal remains occur in the gravels at the site, which are uncemented. The mammalian assemblage is characteristic of the mid-Middle Pleistocene (MIS 12), providing an important constraint on the chronology of incision by the Orontes.

An occupation horizon has been identified within the silty layer, which is ~50m above the modern river level; this is the most famous Palaeolithic site in Syria.
