Gua Tembus (gua = cave) is a rock shelter located on Gunung Pulai in Baling, Kedah, recognized for its potential as a prehistoric settlement site. Excavations conducted in 2020 uncovered a wealth of archaeological evidence, including lithic artifacts, faunal remains, and pottery, which reflect anthropological evolution in response to environmental adaptation. The chronological stratigraphy of these findings dates to the Late Pleistocene period (12,150 ± 40 BP), allowing for the reconstruction of prehistoric cultural dynamics along the West Coast of Peninsular Malaysia. At least three phases of human occupation have been identified within the cave: the Preneolithic or Hoabinhian cultural layer, the Neolithic-influenced cultural layer (3640 ± 30 BP), and a post-prehistoric cultural layer. However, the distribution of various archaeological materials — such as faunal remains, predominantly freshwater mollusk shells, unifacial and bifacial pebble tools, ground tools, and bone artifacts — reveals notable differences across these layers. These variations provide valuable insights into the cultural developments that took place in Kedah during the prehistoric occupation of Gua Tembus, illustrating changes in cultural affinities that likely correspond to shifting environmental conditions and human adaptation over time.
Gua Tembus (Gua =洞穴)是位于吉打州巴陵的古农岛的一个岩石避难所,因其作为史前定居点的潜力而被认可。2020年进行的发掘工作发现了大量考古证据,包括石器制品、动物遗骸和陶器,这些证据反映了人类对环境适应的进化。这些发现的年代地层可以追溯到晚更新世(12,150±40 BP),从而可以重建马来西亚半岛西海岸的史前文化动态。在洞穴内至少确定了人类活动的三个阶段:前新石器时代或霍布汉文化层,新石器时代影响文化层(3640±30 BP),以及后史前文化层。然而,各种考古材料的分布——如动物遗骸,主要是淡水软体动物壳,单面和双面鹅卵石工具,地面工具和骨制品——揭示了这些层之间的显着差异。这些变化提供了对史前Gua Tembus占领期间发生在吉打州的文化发展的宝贵见解,说明了文化亲和力的变化可能与不断变化的环境条件和人类的适应相对应。

The topic of this article concerns our last results on comparative taphonomic studies about human and faunal remains from a Gravettian site in Eastern Europe (Buran-Kaya III, Crimea). Indeed, this site which we excavated some years ago, provided a rich collection of archaeological artefacts especially lithic industry, faunal and human remains mainly for Early Upper Palaeolithic period. One the most important discovery on this site is the presence of an important quantity of human fragments with cutmarks on some of them. We developed a comparative taphonomical study between the two main species of the site. We used classical methods as well as new technological supports (SEM, 3D digital video microscopy, CT-Scan), both on human and saiga antelope remains. This paper aims to describe the modifications observed on the human remains and explore the post-mortem treatment of the bodies, including potential nutritional cannibalism and mortuary practices. To test these hypotheses, we conducted a comparative analysis of the skeletal representation, taphonomic modifications and spatial distribution of human and saiga antelope remains. The results suggest a specific mortuary practice associated with secondary disposal or a non-nutritional cannibalism. Such specific practices are very rare in European Upper Palaeolithic contexts, and are only present in a very small number of sites.
本文的主题涉及我们对东欧格拉维特遗址(克里米亚Buran-Kaya III)人类和动物遗骸的比较分类研究的最新结果。事实上,我们几年前挖掘的这个遗址,提供了丰富的考古文物,特别是石器工业,动物和人类遗骸,主要是旧石器时代早期。该遗址最重要的发现之一是发现了数量可观的人体碎片,其中一些碎片上有刻痕。我们对该地点的两个主要物种进行了比较地语学研究。我们采用传统的方法和新的技术支持(扫描电镜,三维数字视频显微镜,ct扫描)对人类和赛加羚羊的遗骸进行了研究。本文旨在描述在人类遗骸上观察到的修改,并探讨尸体的死后处理,包括潜在的营养同类相食和太平间的做法。为了验证这些假设,我们对人类和赛加羚羊遗骸的骨骼表现、语音学修饰和空间分布进行了比较分析。研究结果表明,这是一种与二次处理或非营养性同类相食有关的特殊的太平间做法。在欧洲旧石器时代晚期,这种特殊的做法是非常罕见的,只存在于极少数的遗址中。

<div><div>The internal cranial base is at the crossroad of the central nervous system (CNS), the occluso-postural balance and the psychomotor control learning with the development of cognitive abilities and mental images. Weidenreich in 1943 compared the <em>Sinanthropus</em> (Chinese <em>Homo erectus</em>) with <span><em>Homo sapiens</em></span> and assumed that the lesser verticalization of its posterior skull base (basi-sphenoid, basi-occipital and petrous pyramids), and, thus, the higher position of the cerebellar fossa, were the results of the more limited anteroposterior growth of the cerebral neocortex (telencephalon). The lesser internal verticality is characteristic of extinct species of the genus <em>Homo</em> which lived before <em>H. sapiens</em> and is clearly visible in comparative anatomy confirmed by the growing number of fossils. Since then, the telencephalic hypothesis became the paradigm. Nevertheless, Weidenreich's hypothesis has been invalidated in 1987 by one of the authors with the discovery of the embryonic origins of the straightening in <em>Homo sapiens</em>. This verticalization is caused by the succession of complex dynamics of the rhombencephalon (future brainstem and cerebellum with the IV ventricle) from the horizontal becoming gradually vertical. Its dynamics cause the plication of the underlying cranial base initially flat, with the dorso-ventral rotation of the basi-sphenoid. We recall this very important discovery given the difficulty of integrating embryogenesis in the sciences of hominization, and present a protocol of angular measurements in 3D to identify hominid species according to their embryonic straightening which increases from great apes to <em>Homo sapiens</em>. The <em>Sinanthropus</em><span> III disappeared in 1941, but the original casts of each disarticulated bone stored at the Institut de Paléontolologie Humaine, Paris, allowed a reconstruction of the inner surface by their computed tomography scan (CT) and then their virtual assembly for a future digital reconstruction of missing parts. The 3D printing has allowed the reconstruction with modeling clay constrained by the preserved conformation. Finally, the prototype has been scanned and compared to the CT scan of 55 living </span><em>Homo sapiens</em> including 30 adolescents and 25 adults with 50% males and 50% females, 41 chimpanzees of increasing age, 3 Javanese <em>Homo erectus</em> of Middle Pleistocene, 5 European <em>Homo neanderthalensis</em> and 2 European <em>Homo sapiens</em> of Upper Pleistocene. The protocol confirms the interest of its application to fossil hominid species (more than 70 specimens) by distinguishing at least three increasing embryonic straightenings: <strong>1)</strong> the chimpanzee (<em>Pan</em>), <strong>2)</strong> extinct species of <em>Homo</em> with <em>H. erectus</em> and <em>H. neanderthalensis</em> and <strong>3)</strong> <em>Homo sapiens</em>.

内颅底是中枢神经系统(CNS)、咬合-体位平衡和精神运动控制学习与认知能力和心理图像发展的十字路口。Weidenreich在1943年将中国人(中国直立人)与智人进行了比较,并假设其后颅底(基底-寰锥、基底-枕锥和岩锥)的垂直度较低,因此小脑窝的位置较高,是大脑新皮层(端脑)的前部生长更有限的结果。较低的内部垂直度是生活在智人之前的已经灭绝的人属物种的特征,并且在越来越多的化石证实的比较解剖学中清晰可见。从那以后,端脑假说成为了范式。然而,Weidenreich的假设在1987年被其中一位作者推翻,因为他发现了智人伸直的胚胎起源。这种垂直化是由菱形脑(未来的脑干和小脑与第四脑室)从水平逐渐变为垂直的复杂动力学的继承引起的。它的动力学导致下颅底的应用最初是平的,随着基底-蝶骨的背-腹侧旋转。鉴于在人类化科学中整合胚胎发生的困难,我们回顾了这一非常重要的发现,并提出了一种3D角度测量方案,根据它们的胚胎矫直度来识别人类物种,从类人猿到智人。中国猿人III于1941年消失,但每一块脱落的骨头的原始模型都保存在巴黎人类医学研究所(Institut de palontolologie Humaine),通过计算机断层扫描(CT)重建了内部表面,然后通过虚拟组装为未来缺失部分的数字重建提供了可能。3D打印允许用受保留构象约束的建模粘土进行重建。最后,对该原型进行了扫描,并与55个现存智人(包括30个青少年和25个男女各占50%的成年人)、41只老年黑猩猩、3只中更新世爪哇直立人、5只欧洲尼安德特人和2只上更新世欧洲智人)的CT扫描结果进行了比较。该协议通过区分至少三种不断增加的胚胎矫直,证实了将其应用于化石人类物种(超过70个标本)的兴趣:1)黑猩猩(Pan), 2)与直立人(H. erectus)和尼安德特人(H. neanderthalensis)一起灭绝的人属物种,3)智人。系统发育上的垂直化与斜脑动力的延长相对应,由于小脑的突然不稳定被迫融入精神运动平衡的控制,这必然会产生产后后果。垂直的第一个阈值是大脑和小脑新皮层之间神经连接复杂性的跳跃,智人的最后一个阈值是小脑“爆炸”。因此,为了更好地理解认知能力的出现,如与脑干的拉直和小脑的新皮质化有关的符号思维的“爆炸”,对不同程度的垂直度进行建模是必要的。

Bioarchaeological methods used to the reconstruction of the dietary patterns of past populations include the analysis of isotopic or chemical elements in bones, with focus on the inorganic component or on bone proteins. Studying bone lipids instead of bone proteins opens up many promising possibilities: they provide insight into dietary intake closer to the time of death and are more closely correlated with the composition of the total diet. The aim of the current study is to compare the archaeological bone fatty acids profile with the elemental composition of bone. The material used in the current study consisted of 20 archaeological human bone samples taken from the cortical bone of the femur, dated to the 17–18th c. The elemental composition of the bone and the bone lipid profile were determined by spectrometric methods. Bone fatty acid content correlated with indices of bone preservation, compared to contemporary bones, archaeological bones tend to have more saturated and very long fatty acids (C22:0 and C24:0). It is most likely that longer fatty acids are better preserved in archaeological bones and reflect mainly bone cellular lipids.
用于重建过去人群饮食模式的生物考古学方法包括分析骨骼中的同位素或化学元素,重点是无机成分或骨骼蛋白质。研究骨脂而不是骨蛋白开辟了许多有希望的可能性:它们提供了更接近死亡时间的饮食摄入的见解,并且与总饮食的组成更密切相关。目前研究的目的是比较考古骨脂肪酸谱与骨的元素组成。目前研究中使用的材料包括20个考古人骨样本,取材于17 - 18世纪的股骨皮质骨。骨头的元素组成和骨脂质谱是通过光谱法确定的。骨脂肪酸含量与骨骼保存指标相关,与当代骨骼相比,考古骨骼往往含有更多饱和脂肪酸和超长脂肪酸(C22:0和C24:0)。最有可能的是,较长的脂肪酸在考古骨骼中保存得更好,主要反映了骨细胞脂质。

A new analysis of the neurocranium and mandible of the Skhūl I child: Taxonomic conclusions and cultural implications Skhūl儿童神经头盖骨和下颌骨的新分析:分类结论和文化意义

The first individual discovered at Skhūl Cave in 1931 on Mount Carmel in Israel was a child aged between 3 and 5 years, intentionally buried ca. 140 ka ago. The fossil was allocated to Homo sapiens, Homo neanderthalensis, or a hybrid of the two species, and is currently recognized as “Anatomically Modern Human”. The incomplete mandible inadvertently separated from the skeleton during excavation, has been reconstructed and consolidated with plaster and appears to be plesiomorphic, with a strong affinity to the Neanderthal clade. The absence of the mid-face and of a large part of the skull base makes its articulation impossible. A new study using CT scans of the neurocranium and mandible was therefore undertaken to clarify their association and taxonomic status. The right bony labyrinth and the enamel-dentine junction (EDJ) of M1 have been virtually reconstructed for the current study and compared to other Homo fossils. The bony labyrinth was compared with two “Western” Neanderthals, La Ferrassie 1, La Quina H5 and one Homo sapiens, Cro-Magnon 1. The frontal squama was initially mispositioned and has been virtually realigned to a more anatomically accurate orientation through comparison with the Neandertal child Le Pech--’Azé. The shape of the bony labyrinth is anatomically modern, but the vault is low, the occipital is elongated with a slight nuchal plane, the foramen magnum is dorsally located, the anterior dentoalveolar shape of the mandible is characteristic of Neanderthal and there is no mentum osseum. The EDJ of M1 is plesiomorphic with a mid-trigonid crest also commonly seen in Neanderthals. Such mosaic of Homo sapiens, Neanderthals, and plesiomorphic characters are also seen in the post-cranial skeleton. The combination of features seen in Skhūl I may suggest that the child is a hybrid. In the Middle Pleistocene, the Levant was the crossroad of gene flows between Indigenous lineages and other taxa from Africa and Eurasia which is likely the explanation for Skhūl I anthropological. Therefore, contrary to the prevailing paradigm, the earliest known mortuary practices involving burials cannot be attributed exclusively to Homo sapiens over Homo neanderthalensis. A new chapter opens on both the origins and motivations of these rituals.
1931年在以色列卡梅尔山Skhūl洞穴中发现的第一个人是一个年龄在3到5岁之间的孩子,大约在140万年前被故意埋葬。该化石被划分为智人、尼安德特人或两种物种的混血儿,目前被认为是“解剖学上的现代人”。在挖掘过程中不慎从骨骼中分离出来的不完整的下颌骨已经被重建并用石膏加固,看起来是半形的,与尼安德特人的分支有很强的亲和力。脸部中部和大部分颅底的缺失使其无法连接。因此,一项利用CT扫描神经头盖骨和下颌骨的新研究被用来澄清它们的关联和分类地位。M1的右侧骨迷路和釉质-牙本质连接(EDJ)已被虚拟重建,并与其他人属化石进行了比较。该骨迷宫与两个“西方”尼安德特人La Ferrassie 1, La Quina H5和一个智人Cro-Magnon 1进行了比较。前额鳞片最初定位错误,通过与尼安德特人的孩子Le peech - ' az进行比较,实际上已经重新排列到解剖学上更准确的方向。骨迷宫的形状在解剖学上是现代的,但拱顶较低,枕部较长,有轻微的颈平面,枕骨大孔位于背侧,下颌骨的前牙槽形状是尼安德特人的特征,没有门骨。M1的EDJ是半形的,具有中三角嵴,也常见于尼安德特人。智人、尼安德特人和非纯形人的这种嵌合体在后颅骨骨骼中也可以看到。在Skhūl I中看到的特征组合可能表明这个孩子是一个混血儿。在中更新世,黎凡特是土著谱系与来自非洲和欧亚大陆的其他分类群之间基因流动的十字路口,这可能是Skhūl I人类学的解释。因此,与流行的范式相反,已知最早的涉及埋葬的殡葬实践不能完全归因于智人而不是尼安德特人。这些仪式的起源和动机开启了新的篇章。

The shape of the bony labyrinth is anatomically modern, but the vault is low, the occipital is elongated with a slight nuchal plane, the <em>foramen magnum</em> is dorsally located, the anterior dentoalveolar shape of the mandible is characteristic of Neanderthal and there is no <em>mentum osseum</em>. The EDJ of M1 is plesiomorphic with a mid-trigonid crest also commonly seen in Neanderthals. Such mosaic of <em>Homo sapiens</em>, Neanderthals, and plesiomorphic characters are also seen in the post-cranial skeleton. The combination of features seen in Skhūl I may suggest that the child is a hybrid. In the Middle Pleistocene, the Levant was the crossroad of gene flows between Indigenous lineages and other taxa from Africa and Eurasia which is likely the explanation for Skhūl I anthropological. Therefore, contrary to the prevailing paradigm, the earliest known mortuary practices involving burials cannot be attributed exclusively to <em>Homo sapiens</em> over <em>Homo neanderthalensis</em>. A new chapter opens on both the origins and motivations of these rituals.</div></div>","PeriodicalId":46860,"journal":{"name":"Anthropologie","volume":"129 3","pages":"Article 103385"},"PeriodicalIF":0.6,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144279847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emergence of the cognitive use of numbers and numerical systems is still poorly explored in prehistoric archeology and cognitive science. A few studies have investigated the topic based on alternative hypotheses, namely that a symbolic numerical thought emerged in a relatively recent past and is mostly culturally based or, on the contrary, that it is a biologically grounded trait as shown by a long evolutionary history that humans share in part with other animals. We hypothesize that evolutionary biological mechanisms and cultural learning are interacting with each other within the hominin clade, building the cognitive bases of our numerical thinking through a complex process that has required a long time to develop. We analyze exemplary findings from a not-abundant but still significant archaeological record that conveys numerical information, and that can be attributed not only to Homosapiens but also to earlier hominin species, Homo erectus and Homo neanderthalensis. We aim to show that transitioning from “quantical” numerosity (also defined as “the number sense”: a perception of quantities we share with other non-human species) to cognitive numerical thinking requires an interplay of neural and molecular structures as biological prerequisites interacting with the cultural transmission. Our interpretation of the archaeological record and a biological-cultural process observed from Homo erectus to Homosapiens supports the hypothesis that the ability to use numerical concepts is part of a broader symbolic abstract cognition. In this context, the cognitive idea of number surpasses the mere “interpretation” of the meaning of the archaeological object. Archaeological artifacts possess structural, unintended properties that can acquire significance in contexts other than their original purpose (McLaughlin, 2014).
在史前考古学和认知科学中,对数字和数字系统的认知使用的出现仍然知之甚少。一些研究基于其他假设调查了这个话题,即象征性的数字思想出现在相对较近的过去,主要是基于文化的,或者相反,它是一种基于生物学的特征,正如人类与其他动物部分共享的漫长进化历史所显示的那样。我们假设,进化的生物机制和文化学习在古人类分支中相互作用,通过一个需要很长时间才能发展的复杂过程,建立了我们数字思维的认知基础。我们分析了一个不丰富但仍然重要的考古记录的典型发现,这些记录传达了数字信息,不仅可以归因于智人,还可以归因于更早的人类物种,直立人和尼安德特人。我们的目标是表明,从“数量”的数量(也被定义为“数字感”:我们与其他非人类物种共享的数量感知)到认知数字思维的过渡需要神经和分子结构的相互作用,作为生物先决条件与文化传播相互作用。我们对从直立人到智人的考古记录和生物文化过程的解释支持这样的假设,即使用数字概念的能力是更广泛的象征性抽象认知的一部分。在这种情况下,对数字的认知观念超越了对考古对象意义的单纯“解释”。考古文物具有结构上的、意想不到的特性,可以在其原始用途以外的环境中获得意义(McLaughlin, 2014)。

New data from the excavations at Boncuklu Tarla reveal that objects previously classified as ambiguous stone artefacts, tokens, or more commonly stone earplugs, are, in fact, labret earrings. The discovery of these objects in situ during the excavations has, more specifically, led to a reevaluation of their definition. Our study of the burials in which these objects were found not only validate their use as body ornaments but also provide further data highlighting their significance. We can now engage in a discussion of concepts such as individual and social identity, taking into account the age and gender of the individuals associated with these objects. This article therefore aims to discuss the earrings and labrets recovered from burial contexts during the 2017 excavation season at Boncuklu Tarla, establishing their typology and focusing on the age and gender of the deceased wearing them, while reinterpreting them through the lens of identity.
来自Boncuklu Tarla考古发掘的新数据显示,以前被归类为模棱两可的石头工艺品、代币或更常见的石头耳塞的物品,实际上是labret耳环。更具体地说,在挖掘过程中发现的这些物品,导致了对它们定义的重新评估。我们对发现这些物品的墓葬的研究不仅证实了它们作为身体装饰品的用途,而且还提供了进一步的数据,突出了它们的重要性。我们现在可以讨论个人和社会身份等概念,同时考虑到与这些物体相关的个人的年龄和性别。因此,本文旨在讨论2017年在Boncuklu Tarla挖掘季节从埋葬环境中发现的耳环和小耳环,建立它们的类型学,并关注佩戴它们的死者的年龄和性别,同时通过身份的视角重新解释它们。

La para-fonction dentaire chez les Hommes Anatomiquement Modernes d’Algérie : les exemples pléistocènes et holocènes des régions septentrionales 阿尔及利亚解剖学上的现代人的牙科辅助功能:更新世和全新世北部地区的例子

When studying the cranial series of Anatomically Modern Humans from Algeria (Upper Paleolithic, Epipaleolithic, Neolithic) from the perspective of cranio-facial and occlusal morphogenesis, some adult individuals of both sexes presented abrasive wear, especially of the cheek teeth, which did not fit with that resulting from classic physiological mastication. It seemed essential to us to verify the entire dental series from the sites of Algeria since the Upper Paleolithic. Among this set, certain dental series of the Mechta-Afalou Iberomaurusians, the Capsian Proto-Mediterraneans and those of the Mediterranean Neolithic of western Algeria show abrasive wear of the cheek teeth, generally with vestibular and/or lingual obliquity, suggesting a para-function (or para-mastication). We analyzed five individuals, four of which came from the sites of Afalou-Bou-Rhummel, Taza 1, Oued Guettara, and Medjez II. The fifth individual, from the collections of the Bardo National Public Museum in Algiers, does not mention its origin; however, its craniofacial and dental morphology brings it closer to Holocene specimens.
从颅面和咬合形态发生的角度研究阿尔及利亚解剖学现代人(上旧石器时代、上石器时代、新石器时代)的颅骨系列时,一些男女成年个体出现磨蚀磨损,尤其是颊齿,这与经典的生理咀嚼产生的磨蚀不相符。对我们来说,从旧石器时代晚期开始验证阿尔及利亚遗址的整个牙齿系列似乎是至关重要的。在这组牙齿中,来自Mechta-Afalou Iberomaurusians、Capsian原地中海人和阿尔及利亚西部地中海新石器时代的某些牙齿系列显示出面颊牙齿的磨蚀磨损,通常具有前庭和/或舌侧倾斜,表明具有准咀嚼功能(或准咀嚼)。我们分析了5个个体,其中4个来自afalou - bu - rhummel, Taza 1, Oued Guettara和Medjez II。第五件来自阿尔及尔巴尔多国家公共博物馆的藏品,没有提到它的来源;然而,它的颅面和牙齿形态使它更接近全新世标本。

Estimating the age at death of human remains is fundamental for the analysis and interpretation of skeletal evidence in various disciplines, including forensic science, archaeology, and paleoanthropology. This study aims to explore age estimation in prehistoric humans, specifically Pawon Man, through two primary methods: pulp volume analysis using Cone Beam Computed Tomography (CBCT) 3D and DNA methylation analysis of teeth, also to unveil a deeper comprehension of Pawon Man's life trajectory and its significance in the realm of human evolution. This descriptive study focused on two maxillary fragments of Pawon Man group Rangka V (R.V.), specifically first premolar and second molar. Age estimation based on CBCT 3D imaging was derived by semi-automatically measuring the pulp volume using ITK-SNAP software (version 3.8.0). DNA methylation analysis was performed on the ELOVL2 gene using pyrosequencing, with age estimation based on the percentage of methylated reference (PMR). Age estimation obtained using the CBCT 3D method was 30.711 ± 0.811 years (95% CI) for sample 1 and 16.998 ± 1.208 years (95% CI) for sample 2. In contrast, DNA methylation analysis provided age estimation of 34.602 years for sample 1 and 17.841 years for sample 2. The significant discrepancy in age estimation between the two methods highlights the complexity and variability inherent in age estimation approaches. Age estimation using CBCT 3D and DNA methylation shows significant differences due to methodological variations and the absence of universal regression standards. Integrating both methods is essential to improve accuracy and establish more consistent research protocols in ancient human analysis.
估计人类遗骸的死亡年龄是分析和解释各种学科骨骼证据的基础,包括法医学、考古学和古人类学。本研究旨在通过锥形束计算机断层扫描(CBCT)三维牙髓体积分析和牙齿DNA甲基化分析两种主要方法来探索史前人类,特别是Pawon Man的年龄估计,并进一步了解Pawon Man的生活轨迹及其在人类进化领域的意义。本研究对Pawon Man类群Rangka V (R.V.)的两个上颌碎片进行了描述性研究,具体为第一前磨牙和第二磨牙。使用ITK-SNAP软件(版本3.8.0)半自动测量牙髓体积,得出基于CBCT三维成像的年龄估计。使用焦磷酸测序对ELOVL2基因进行DNA甲基化分析,并根据甲基化参比百分比(PMR)估计年龄。使用CBCT 3D方法估计样本1的年龄为30.711±0.811岁(95% CI),样本2的年龄为16.998±1.208岁(95% CI)。相比之下,DNA甲基化分析提供的样本1的年龄估计为34.602岁,样本2的年龄估计为17.841岁。两种方法在年龄估计上的显著差异突出了年龄估计方法固有的复杂性和可变性。由于方法差异和缺乏通用回归标准,使用CBCT 3D和DNA甲基化进行年龄估计显示出显着差异。整合这两种方法对于提高古人类分析的准确性和建立更一致的研究方案至关重要。

The Megalitho da Cabecinha Grande (Figueira da Foz, Coimbra, Portugal) is one of the many dolmens of the Atlantic megalithic necropolis explored by António Santos Rocha at the end of the nineteenth century. A very fragmentated, disarticulated, and poorly preserved assemblage of human skeletal remains was recovered from a disturbed chamber. These correspond to a minimum of 18 individuals: 10 adults (both sexes) and 8 non-adults. Elevated biomechanical stress is suggested based on several skeletal markers that include non-metric traits and the thickness of femoral cortical bone, elevated robustness of several other long bone diaphysis, and a Schmorl's node on a lumbar vertebra. Osteological analysis was supplemented with examination of written sources from the excavation to gain inferences about funerary practices. The dolmen architecture, artefacts and radiocarbon dating of a human bone sample, confirm the Chalcolithic chronology. The importance of these skeletal remains derives not only from their being recovered from an expansive megalithic necropolis, but also because they come from a region represented by poorly preserved human skeletal remains.
Megalitho da Cabecinha Grande(葡萄牙科英布拉的Figueira da Foz)是António Santos Rocha在19世纪末探索的大西洋巨石墓地的众多墓碑之一。从一个被破坏的房间里发现了一组非常破碎、脱节、保存不良的人类骨骼遗骸。这些对应于至少18个个体:10个成年个体(男女)和8个非成年个体。生物力学应力升高是基于几个骨骼标记,包括非度量特征和股皮质骨的厚度,其他几个长骨骨干的健壮性升高,以及腰椎的Schmorl淋巴结。通过对发掘的文字资料进行检查,补充了骨骼学分析,以获得有关丧葬习俗的推论。墓室建筑、人工制品和人类骨骼样本的放射性碳定年,证实了铜石器时代的年代。这些骨骼遗骸的重要性不仅在于它们是从一个巨大的巨石墓地中发现的,还因为它们来自一个保存完好的人类骨骼遗骸的地区。
