JOURNAL OPEN ACCESSIn order to reconsider the absolute chronology of sediment layers and types of pottery from the incipient to early Jomon periods at the Torihama shell midden site, we conducted radiocarbon dating on 32 samples of plant macrofossils obtained from sediment samples from research areas 81L (1981), 82T (1982), and 83T (1983). The sediment layers containing early Jomon pottery of the Kitashirakawa Kaso II types (83T, layers 6–31) were dated to ca. 5990–5655 cal BP, and those containg pottery of the Kitashirakawa Kaso Ib and Hashima Kaso II types (83T, layers 34–77) were dated to ca. 6500–6190 cal BP. Examples of roulette-patterned pottery (Oshigatamon) from the initial Jomon period excavated from sediments above and below the Mikata tephra layer (UOki) were dated to ca. 9675–9535 cal BP (81L, layers 38–41) and ca. 10,495–10,250 cal BP (81L, layers 43–44), respectively. Sediment layers including cord-marked pottery (Tajomon) from the incipient Jomon period were dated to ca. 11,615–11,280 cal BP (81L, layer 49). These radiocarbon dates, along with paleoenvironmental information from pollen and plant macrofossils from the same sediment samples, enable us to clarify the change in human-environment interactions from the incipient to early Jomon periods (ca. 15,000–5500 cal BP) at this site.View full abstractDownload PDF (1147K) -

JOURNAL OPEN ACCESSDuring excavation from 1965 to 1985, over three thousand pieces of fossil wood from the Jomon period were found at the Torihama shell midden site, Fukui Prefecture, Japan. Previous identifications of natural woods and wooden artifacts from this site revealed 57 pieces of Castanea crenata wood and eight wooden artifacts that can be placed stratigraphically in the incipient Jomon period. Verification of the absolute ages of these specimens, the oldest known remains of Castanea crenata, is an important issue for resolving human-plant relationships in the Jomon period. Radiocarbon dating of three pieces of natural wood showed that all of them can be placed in 12,740–11,835 cal BP of the crescent and cord-marked (Tumegatamon and Ouatsumon) pottery phase of the incipient Jomon period. Seven artifacts of Castanea crenata were dated at 12,035–11,250 cal BP of the cord-marked (Tajomon) pottery phase of the incipient Jomon or at 7940–7675 cal BP of the later phase of the initial Jomon period. These data provide clear evidence for the occurrence of Castanea crenata around the Torihama shell midden site in the incipient Jomon period as well as the use of this tree by hunter-gatherers.View full abstractDownload PDF (1347K) -

JOURNAL OPEN ACCESSTo reconstruct the distribution of vegetation and use of plant resources at the Torihama shell midden site, Fukui, Japan, from the incipient to early Jomon periods, analyses of fossil pollen and plant macrofossils were carried out together with radiocarbon dating. We identified six vegetation stages from the composition of arboreal pollen assemblages and radiocarbon dates: forests of Lepidobalanus and Fagus (ca. 14,000–13,200 cal BP), Fagus forests with Cryptomeria trees (ca. 11,600 cal BP), Lepidobalanus forests with abundant Castanea trees (ca. 11,500–8700 cal BP), Cryptomeria forests with an increase in Celtis–Aphanathe trees (ca. 8700–7100 cal BP), an increase in Cyclobalanopsis trees (ca. 7100–5700 cal BP), and dominance of Castanae trees (after ca. 5700 cal BP). Use of Castanea crenata appears to have started in the incipient Jomon period. In this period, C. crenata trees appear to have grown abundantly within Lepidobalanus forests on a nearby hill and were probably maintained artificially. During the incipient Jomon period, Toxicodendron vernicifluum and Cannabis sativa had grown around this site since ca.13,200 cal BP and ca. 10,500 cal BP, respectively. Throughout the incipient to early Jomon periods, an increasing number of taxa appear to have been used as plant resources around this site.View full abstractDownload PDF (2036K)
