Histomorphological species identification of tiny bone fragments from a Paleolithic site in the Northern Japanese Archipelago
AbstractBone histomorphology is an effective method for species identification of fragmentary osseous remains. The 1997–1998 excavations of the Kashiwadai 1 Upper Paleolithic site (ca. 22–20.5 kyBP) in Hokkaido (the northern island of the Japanese Archipelago) yielded tiny bone fragments, which had been burned to white and broken into pieces less than 1 cm in size, making their species identification by gross morphology alone impossible. For the purpose of species identification, histomorphological analyses were performed on thin sections of the Kashiwadai 1 bone fragments. Compact bone cross sections taken from medium- to large-sized land mammals in the Pleistocene and Holocene Hokkaido were prepared for comparison. The structures of the Kashiwadai 1 samples consisted of secondary osteons and plexiform bone. Consideration of the presence versus absence of plexiform bone and quantitative assessments of osteon sizes and bone cortical thickness allows for distinction between medium-sized deer, large-sized artiodactyls, small- to medium-sized carnivores, large-sized carnivores, elephants, and humans. The histomorphological characteristics of the Kashiwadai 1 samples were quite similar to those of both sika deer and ancient sika deer. A probable conclusion is that medium-sized deer was the primary game hunted by Paleolithic people at the Kashiwadai 1 site. Interestingly, the samples did not include elephant or large-sized artiodactyls, which were the predominant species in other Paleolithic sites of the Japanese Archipelago. This is the first evidence of human hunting medium-sized animals in the Upper Paleolithic period of the Japanese Archipelago based on faunal remains

Paleopathological characteristics of Neolithic early rice farmers in the lower reaches of the Yangtze river
Paleopathological investigations of human remains from the Neolithic Hemudu culture in the lower reaches of the Yangtze River in southern East Asia were conducted to clarify the health status of people in early rice-farming societies. Our results show that the occurrence ratios of cribra orbitalia and enamel hypoplasia did not differ significantly between early rice farmers and hunter-gatherers. By contrast, the occurrence ratios of periosteal reactions, dental caries, and antemortem tooth loss in adults were higher among the early rice farmers. Based on these findings and the results of archaeological research on the Hemudu culture, it was suggested that: 1) the Hemudu culture adopted a diversified livelihood strategy that was not overly dependent on rice as a food resource, which did not lead to an extreme decline in health status, 2) the work in the rice fields or the working environment caused stress to the workers, and 3) the rice-farming society’s dietary habits led to a decline in oral health. Our results provide new paleopathological insights into the health status of early rice farmers in East Asia. However, the sample size of early rice farmers used in this study was small, and more data are needed to verify the validity of the views presented here
