Pebble tools, including choppers and chopping tools, are found in the Pleistocene terrace deposits of the Irrawaddy River valley of northern Myanmar. This complex is known as the Anyathian. The Early Anyathian is characterized by single-edged core implements made on natural fragments of fossil wood and silicified tuff, and these are associated with flake implements. In the Late Anyathian, a direct development from the earlier stage, smaller and better-made core and flake artifacts are found. No hand axes or flakes produced by the prepared striking-platform–tortoise-core technique have been found in Myanmar.

Elsewhere in this region, pebble tools have been reported from deposits apparently of Middle Pleistocene age in western Thailand, for which the name Fingnoian has been proposed. In northern Malaysia a large series of choppers and chopping tools made on quartzite pebbles and found in Middle Pleistocene tin-bearing gravels have been referred to collectively as the Tampanian, since they come from a place called Kota Tampan in Perak. Still another late Middle Pleistocene assemblage, called the Patjitanian, is known from a very prolific site in south-central Java. In both the Tampanian and Patjitanian the main types of implements consist of single-edged choppers and chopping tools that occur in association with flakes with unprepared, high-angle striking platforms. Also in both assemblages is an interesting series of pointed, bifacial implements that have been described as hand axes. Since these tools are very rare in each instance and are absent in Myanmar, it is probable that they were developed in southeastern Asia independently of influences from the west. Several sites of Upper Pleistocene age in central Java have produced artifacts made on small to medium-sized flakes and flake blades. Antler and bone implements belong to this complex, known as the Ngandongian, which has also been reported from the Celebes and from the Philippines.

One of the oldest Lower Paleolithic occupation sites ever discovered is near the village of Zhoukoudian, about 48 km (30 miles) southwest of Beijing in northern China. Associated with the remains of Peking man (Homo erectus pekinensis, formerly Sinanthropus pekinensis), pebble tools, together with quartz-flake implements, occur in quantity. This assemblage, which is known as the Zhoukoudianian, is of Middle Pleistocene age; it forms an integral part of the chopper-chopping tool tradition of East and Southeast Asia.

Also in northern China, several Upper Paleolithic sites are known in the provinces of Shanxi, Shaanxi, and northern Gansu, in the region encompassed by the great bend of the Yellow River (Huang He). Collectively known as the Ordosian, these materials are of Upper Pleistocene age. Typical of the Ordosian are blade implements of various types, points and scrapers of Mousterian-like appearance, and pebble tools of Zhoukoudianian tradition. This development was originally classified as Moustero-Aurignacian, but it later became apparent that it had much in common with that of the Yenisey–Baikal region to the north, in central Siberia.

Siberia

The archaeological materials from the loess sites of Siberia between the Yenisey valley and the Lake Baikal area are an interesting mixture of (1) blade tools, together with antler, bone, and ivory artifacts of classic Upper Paleolithic type, (2) points and scrapers made on flakes of Mousterian aspect, and (3) pebble tools representing a survival of the ancient chopper–chopping tool tradition of eastern Asia. Remains of semi-subterranean dwellings with centrally located hearths occur at certain of these stations, together with female statuettes in bone. One of the most striking features of this Siberian Upper Paleolithic is the fact of its comparatively late survival: in terms of the European sequence, it seems to have persisted as late as Early Mesolithic times. Indeed, in several instances it actually occurs in the uppermost layer of loess immediately below a horizon of humus containing Neolithic campsites. The problems of the Siberian Upper Paleolithic are of obvious importance to students of New World archaeology, since they have an intimate and direct bearing on the question of the peopling of the Americas.
