This paper describes recent material gathered during the second fieldwork at Ma U'Oi in November 2002 by a Vietnamese-French-Japanese team. The Ma U'Oi cave, located in the province of Hoa Binh (60 km SW from Hanoi), northern Vietnam, belongs to a karstic network developed in Triassic dark-grey limestones. The cave is filled with coarse-grained breccias containing numerous fossil remains, partially preserved at several-loci inside the cave (wall, vault and ground). We describe new teeth which confirm the occurrence of mammal taxa already mentioned at Ma U'Oi (Bacon et al., 2004)[Bacon, A-M., Demeter, F., Schuster, M., Long, VT., Thuy, N.K., Antoine, P-O., Sen, S., Nga, H.H., Huong, N.T.M., 2004. The Pleistocene Ma U'Oi cave, northern Vietnam: palaeontology, sedimentology and palaeoenvironments. Geobios 37, 305-314], while others, mainly microvertebrates, emphasize the occurrence of new species for the Pleistocene of Vietnam. We report here, for the first time, the occurrence of these microvertebrates of different groups (primates, rodents, insectivores, small reptiles and amphibians) in the faunal assemblage. Among mammal taxa, the presence of one more hominid affiliated to archaic Homo is also attested by our findings. U/Th dating carried out on 2 samples extracted from breccia speleothems confirms the biochronological estimate, with fossiliferous fillings ranging from late Middle Pleistocene to Late Pleistocene.

Diffuse idiopathic skeletal hyperostosis in Late Jomon Hokkaido, Japan

MF Oxenham, H Matsumura, T Nishimoto

INTERNATIONAL JOURNAL OF OSTEOARCHAEOLOGY ( JOHN WILEY & SONS LTD ) 16 ( 1 ) 34 - 46 2006.01 [Refereed]

The purpose of this study is to describe and analyse the evidence for diffuse idiopathic skeletal hyperostosis (DISH) in samples of human skeletal material recovered from Late Jomon (ca. 1500-300 BCE) and Okhotsk (CE 500-900) cultural period sites, northwestern Hokkaido, Japan. Two individuals from the Jomon period assemblage (n=14) exhibited lesions consistent with DISH, while the larger Okhotsk sample (n=39) was free of this condition. The aetiology of this condition is reviewed with reference to the clinical and bioarchaeological literature, in addition to behavioural and environmental considerations specific to this region and these time periods.

Embodying Okhotsk ethnicity: Human skeletal remains from the Aonae Dune site, Okushiri Island, Hokkaido

Hirofumi Matsumura, Mark J. Hudson, Kenichiro Koshida, Yoichi Minakawa

Asian Perspectives ( University of Hawaii Press ) 45 ( 1 ) 1 - 23 2006 [Refereed]

This article describes human skeletal remains from the Aonae Dune site, Okushiri Island, Hokkaido, Japan. Skeletal remains of an adult female and two subadults were excavated in 2002. Although these remains derived from Okhotsk culture contexts, analyses of cranial and tooth crown measurements demonstrated that Aonae Dune No. 1 (the adult female), Aonae Dune No. 2 (a child of about 11 years), and Aonae Dune No. 3 (a child of about 6 years) are morphologically closer to Epi-Jōmon or Jōmon and Ainu populations and significantly different from other Okhotsk samples in Hokkaido. It is argued that these three skeletons probably represent individuals from a different culture who were adopted into Okhotsk society. © 2006 by the University of Hawai'i Press.

Dental perspectives on the population history of southeast Asia

H Matsumura, MJ Hudson

AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY ( WILEY-BLACKWELL ) 127 ( 2 ) 182 - 209 2005.06 [Refereed]

This article uses metric and nonmetric dental data to test the "two-layer" or immigration hypothesis whereby Southeast Asia was initially occupied by an "Australo-Melanesian" population that later underwent substantial genetic admixture with East Asian immigrants associated with the spread of agriculture from the Neolithic period onwards. We examined teeth from 4,002 individuals comprising 42 prehistoric and historic samples from East Asia, Southeast Asia, Australia, and Melanesia. For the odontometric analysis, dental size proportions were compared using factor analysis and Q-mode correlation coefficients, and overall tooth size was also compared between population samples. Nonmetric population affinities were estimated by Smith's distances, using the frequencies of 16 tooth traits. The results of both the metric and nonmetric analyses demonstrate close affinities between recent Australo-Melanesian samples and samples representing early Southeast Asia, such as the Early to Middle Holocene series from Vietnam, Malaysia, and Flores. In contrast, the dental characteristics of most modern Southeast Asians exhibit a mixture of traits associated with East Asians and Australo-Melanesians, suggesting that these populations were genetically influenced by immigrants from East Asia. East Asian metric and/or nonmetric traits are also found in some prehistoric samples from Southeast Asia such as Ban Kao (Thailand), implying that immigration probably began in the early Neolithic. Much clearer influence of East Asian immigration was found in Early Metal Age Vietnamese and Sulawesi samples. Although the results of this study are consistent with the immigration hypothesis, analysis of additional Neolithic samples is needed to determine the exact timing of population dispersals into Southeast Asia.

Discovery of a second human molar and cranium fragment in the late Middle to Late Pleistocene cave of Ma U'Oi (Northern Vietnam)

F Demeter, AM Bacon, KT Nguyen, VT Long, P Duringer, S Rousse, Y Coppens, H Matsumura, Y Dodo, MH Nguyen, A Tomoko

JOURNAL OF HUMAN EVOLUTION ( ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD ) 48 ( 4 ) 393 - 402 2005.04 [Refereed]

In November 2002, during the second season of work by a Vietnamese-French-Japanese team, we discovered a human molar and a fragment of an occipital bone in the late Middle to Late Pleistocene cave of Ma U'Oi (Bacon et al., Geobios. 37 (2004) 305). The layer from which this material comes is the same as that in which a human lower molar was found in 2001. Both molars can be attributed to archaic Homo, and both exhibit archaic and modern traits. En Novembre 2002, lors de la seconde campagne de fouille conduite par une equipe vietnamienne-franco-japonaise, nous avons decouvert une molaire et un fragment d'os occipital humains dans la grotte Pleistocene moyen a superieur de Ma U'Oi (Bacon et al., 2004). Le niveau d'ou provient ce materiel est le meme que celui ou avait ete trouvee en 2001, une molaire inferieure. Les deux molaires peuvent titre attribuees a Homo archaique et presentent toutes les deux, a la fois des caracteres modernes et archaiques. (c) 2004 Elsevier Ltd. All rights reserved.

Are difficulties during transbronchial lung biopsy/brushing through a fiberoptic bronchoscope based on the bronchial anatomy?

Surgical and Radiologic Anatomy 27 ( 2 ) 94 - 99 2005.04 [Refereed]

Some of the difficulties encountered during transbronchial lung biopsy through a flexible bronchofiberscope are due to anatomical reasons, namely the branching angles of some subsegmental bronchi from their mother bronchi are large, and differences in branching angles during respiration may also be large. This makes insertion of forceps difficult. We have sometimes experienced difficulties reaching the target lesion during a transbronchial approach. Which subsegmental bronchi make transbronchial lung biopsy/brushing difficult, and are such difficulties due to anatomical reasons? To answer these questions, we firstly surveyed 10 bronchologists regarding which five subsegmental bronchi they considered to be the most difficult for transbronchial biopsy/brushing. We then measured the branching angles of subsegmental bronchi in 106 cadaver lungs. Finally, in six volunteers, we also measured differences in branching angles of the subsegmental bronchi between the point of forced inspiration and the point of forced expiration on CT images. According to the survey, left B1+2c was considered to be the most difficult for insertion by nine doctors, followed by bilateral B6a by seven, right B1a by five, left B3a by five and left B1+2a by four. The results of our dissections showed that a branching angle of over 60o was present in more than 10% of specimens in B3a, B6a and B6c in the right lung and in B1+2c, B3a, B6a and B6c in the left lung. In addition, three-dimensional reconstructed images revealed that the angles of some subsegmental bronchi changed during respiration. Inter-individual variations were present in most subsegmental bronchi. The direction of movement of each subsegmental bronchus during respiration varied. In addition, maximum degrees of difference in angles between volunteers were sometimes as much as 80°. In conclusion, branching angles of subsegmental bronchi from their mother bronchi are large in B3a, B6a and B6c in the right lung and in B1+2c, B3a, B6a and B6c in the left lung. Most of these correspond to those which many bronchologists felt to be difficult for insertion. In addition, changes in the angles of subsegmental bronchi during respiration are likely to partially account for difficulties encountered during transbronchial approaches. © Springer-Verlag 2004.

A morphometric analysis of the Late Pleistocene Human Skeleton from the Moh Khiew Cave in Thailand.

Homo : internationale Zeitschrift fur die vergleichende Forschung am Menschen ( URBAN & FISCHER VERLAG ) 56 ( 2 ) 93 - 118 2005 [Refereed] [International journal]

Few Late Pleistocene human remains have been found in Southeast Asia and the morphological features of the people of that age are still largely unknown due to the virtual lack of human remains in the area. Recent excavations at the Moh Khiew Cave in Thailand resulted in the discovery of a Late Pleistocene human skeleton in a relatively good state of preservation. An AMS radiocarbon date on the charcoal sample gathered from the burial gave a result of 25,800 +/- 600 BP, implying that the inhabitants of Moh Khiew Cave resided in a part of Sundaland during the last glacial age. In debates on the population history of Southeast Asia, it has been repeatedly advocated that Southeast Asia was occupied by indigenous people akin to present-day Australo-Melanesians prior to an expansion of migrants from Northeast Asia into this area. Morphometric analyses were undertaken to test the validity of this hypothesis. In the present study, cranial and dental measurements recorded from the Moh Khiew remains are compared with those of early and modern samples from Southeast Asia and Australia. These comparisons demonstrate that the Moh Khiew specimen resembles the Late Pleistocene series from Coobool Creek, Australia in both cranial and dental measurements. These results suggest that the Moh Khiew skeleton, as well as other fossil remains from the Tabon, Niah and Gua Gunung sites, represents a member of the Sundaland population during the Late Pleistocene, who may share common ancestry with the present-day Australian Aborigines and Melanesians.

Morphologic and genetic evidence for the kinship of juvenile skeletal specimens from a 2,000 year-old double burial of the Usu-Moshiri site, Hokkaido, Japan

N Adachi, Y Dodo, N Ohshima, N Doi, M Yoneda, H Matsumura

ANTHROPOLOGICAL SCIENCE ( ANTHROPOLOGICAL SOC NIPPON ) 111 ( 3 ) 347 - 363 2003.07 [Refereed]

This paper presents a case study of a double burial at the 2,000 year-old Usu-Moshiri Epi-Jomon site in Hokkaido, Japan, using detailed odontometric analysis in conjunction with mitochondrial DNA (mtDNA) analysis in order to more precisely assess their kinship. Consanguinity between the two juveniles found in this burial was suggested by the archaeological context as well as by preliminary morphological studies of the skeletons. Mitochondrial DNA sequences, while consistent with their maternal kinship, did not provide decisive evidence. Supplementing and strengthening the kinship determination, Q-mode correlations between these two individuals with respect to tooth crown measurements and proportions were consistently positive and very high. Statistical analysis of the difference between tooth size correlations in this pair, and those in pairs of related and unrelated individuals from other Japanese populations indicated that they likely had been first degree relatives. Considering that the two individuals had been approximately seven and eleven years old at the time of their interment side by side, we concluded that they likely had been siblings rather than other first-degree maternal relatives. This study demonstrated that combining odontological analysis with mtDNA testing may be effective for reliable and detailed kinship assessment of ancient skeletal remains.

It is well known that the human remains of the aeneolithic Yayoi period (ca. B.C. 300 - 300 A.D.) recovered from the Northern Kyushu and Yamaguchi districts in western Japan are considerably different in the skeletal morphology from the Neolithic Jomon natives, and they have been regarded as the immigrants from the Asian Continent or their offspring. The morphological gap between the natives and immigrants is found not only in the skeletons but also in the dentition. In consideration of microevolutionary history of the Japanese people, the expansion of immigrants to eastern Japan during the Yayoi period is one of the crucial problems. In order to approach this problem from an aspect of skeletal morphology, however, preservation of skeletal remains of this period is often in a poor state of condition. Even in case that the skeletal remains are fragile and fragmentary, well preserved teeth are occasionally available to study the morphology. The present author made discriminant function analyses on the tooth crown diameters of the Jomon natives and Yayoi immigrants for the purpose of distinguishing between those of the native and immigrant origins. The most effective discriminant functions correctly assessed the origin in more than 90% of the samples from both sexes. Through the use of the discriminant functions obtained, the Yayoi remains from eastern Japan were classified as of the native or immigrant type. The results suggest that the earliest immigrants diffused into central Japan, including the Kanto region.The influence of the Yayoi culture associated with rice cultivation had little impact on Hokkaido, the northernmost island of Japan. There the Jomon period is followed by a so-called epi-Jomon, which corresponds to the Yayoi period on the other main islands. Various researchers have reported that the cranial morphology of the epi-Jomon specimens is similar to Jomon cranial morphology. The present study, based on the dental metrics, also classifies most of the epi-Jomon specimens as the Jomon type, which confirms the epi-Jomon people as direct descendants of the preexisting Jomon natives. On the other side, the present study unexpectedly classified several epi-Jomon specimens as the immigrant type with high probabilities, which can be interpreted as evidence for contact with the immigrants on Hokkaido. The specimen from Rebunge site possess features of the Yayoi immigrant, while those form Chatsu IV site have characteristics of another immigrant group, that it, Okhotsk series immigrated from Northeast Asia.
