Several new finds of the Late Pleistocene porcupine (Hystrix brachyura vinogradovi) in the Altai Mountains of southern Siberia and the Urals occur far north of previously assigned range for porcupine. These finds have necessitated a renewed study of this species's chronology and spatial distribution. We conclude that the oldest records of this porcupine in the Ural Mountains date to MIS 5e, and its geographic range possibly included also the Altai at that time. Directly radiocarbon-dated porcupine bones in the Altai fall in MIS 3 (ca. 32,000–41,000 cal BP). It is the northernmost record of this species and the youngest find outside its current geographic range.

During the Late Glacial, hunter-gatherers began using ceramic cooking containers in three separate geographic regions of East Asia: China, Japan and in the Russian Far East. While recent research has clarified the use of early pottery in Japan, very little is known about what led to the emergence of pottery in the other two areas, including the likely environmental, economic or cultural drivers. In this paper we focus on a series of key sites along the Amur River in the Russian Far East, where early pottery has been recovered from securely-dated contexts that span ca. 16,200 to 10,200 years ago (cal BP). Interpreting how these ceramic vessels were used has been difficult because the region’s acidic soils make palaeo-economic reconstructions challenging. To address this gap in knowledge we undertook lipid residue analysis of 28 pot sherds from the sites of Khummi, Gasya, and Goncharka 1 on the Lower Amur River, and the Gromatukha site on the Middle Amur. Our results indicate that pottery was employed to process aquatic oils at sites on the Lower Amur, a pattern of use that aligns closely with studies conducted in Japan, and suggests that fishing – probably of salmonids and freshwater fish – was becoming increasingly important during this period. In contrast, the results from the Middle Amur show a significant contribution of lipids from ruminant animals, indicating that these vessels were being used in different ways. Interestingly, these regional differences in pottery use also map onto contrasting manufacturing techniques, with vessels from the Middle and from the Lower Amur forming distinct pottery-making traditions. These combined insights appear to indicate a greater degree of variability in the development and use of early pottery in East Asia than has hitherto been indicated.

Both the AMS radiocarbon technique and TL dating have been used to study the age of organic-tempered pottery from Gasya, one of the earliest Neolithic sites in the Russian Far East. The results obtained are consistent with the previous set of radiocarbon dates from the site, that were obtained for charcoal, and show that the hypothesis that the earliest pottery from the Amur River basin dates to before 10,000 BP (calendar years) is valid. The organic-tempered pottery from the Russian Far East therefore looks promising for future dating by the AMS radiocarbon and TL methods.
