Stone Age fishhooks – how were they dimensioned? Morphology,strength test,and breakage pattern of Neolithic bone fishhooks from Ajvide,Gotland, Sweden

The late Stone Age Pitted Ware site at Ajvide, Gotland, in the Baltic Sea, Sweden, has revealed a large deposit of fishbone and approximately 400 bone fishhooks, complete and incomplete. Cod (Gadus morhua), which is one of the most abundant fish species in the bone assemblage, was probably caught with hook and line fishing. To investigate the fishhooks' field of application, a morphological and morphometric study was performed on 384 available hooks. Two sets of replicas made of four selected original fishhooks were submitted to a strength test. A breakage study of the incomplete hooks in comparison with the strength-tested hooks was carried out in order to distinguish fresh breaks from dry breaks. It seems that a certain morphology for fishhooks was preferred at Ajvide, indicating they were produced by skilled craftsmen for special usage. The strength test showed that the hooks had a weight bearing capacity more than the average size of cod caught at Ajvide. Using results of these tests, we predicted that the mean breaking strength of 46 intact Ajvide hooks was 96.6 ± 26.1 (s.d.) Newtons (equivalent to 9.85 ± 2.7 kg). The design of fishhooks changed somewhat over time, being slightly larger in the oldest layers of the site. The breakage patterns of the hooks show that the bow was the most common area of breakage. The design and weight bearing capacity of the hooks point to a specialized cod fishery from boats in deep water.     

Atlantic salmon, archaeology and climate change in New England

A paucity of archaeological remains of Atlantic salmon in Northeast North America has been cited as evidence that the species may have been present in the region only during and after the Little Ice Age (ca. 1450–1850 AD), one of coldest periods of the Holocene. However, significant problems of preservation, recovery and identification remain. Here, improved methods of identification use vertebra structure to distinguish salmon from trout, and strontium/calcium ratios to differentiate sea-run from landlocked salmon. In addition to the Little Ice Age, Atlantic salmon is identified in tightly dated contexts at 7000–6500 and 3500–3000 calendar years BP, during climate periods that were comparatively warm and wet.     

Tracking changes in bone fracture morphology over time: environment, taphonomy, and the archaeological record

Zooarchaeologists have often employed studies of bone fracture morphology as a means of understanding past human cultural activity, and various methodological approaches have been developed for analyzing archaeological broken bone assemblages. It is widely understood that bones degrade over time, however, few studies have attempted to define and quantify the rate at which bones degrade and fracture morphologies change. This study examines degradation in frozen bones (−20 °C) and bones exposed to hot (40 °C) dry conditions. These two simulated environmental conditions represent extreme real-world climates, and allow for an actualistic understanding of the rates of degradation that bones experience in nature. When frozen, bones degrade slowly but significantly, and demonstrate measurable differences in samples frozen for 1, 10, 20, 40, and 60 weeks. In hot, dry conditions, bones degrade very quickly, and demonstrate measurable differences after 1, 3, 7, 14, and 21 days. These data allow for a more detailed understanding of the relationship between the cultural and natural processes that result in bone fracture, and the time period during which bones can be expected to maintain fresh fracture characteristics. This research also has implications for understanding human subsistence and survival strategies and for interpreting the archaeological record.     

Specialization of ceramic production: A sherd assemblage based analytic perspective

One expectation of emergent complexity is that as ceramic craft specialization increases it is reflected by increasingly homogeneous products due to the modified organization of craft production by specialists. This question has most often been addressed by analysis of sub-sets of larger ceramic assemblages consisting of intact vessels from idiosyncratic contexts. However, excavations often do not yield appropriate whole vessel sub-sets. In order to evaluate the changing context of the organization of ceramic production, we engage a robust methodological approach to the analysis of ceramic sherd assemblages, rather than intact vessels, rooted in cluster analysis but which we rigorously evaluate by other means. We successfully employ this method to assess changes in the organization of ceramic production through a 1000 year sequence leading to the emergence of the Tarascan state, and conclude in this case that no significant reorganization of ceramic production occurred with Tarascan state formation.     

说花园庄东地甲骨卜辞的“丁”——附:释“速”

最近公布的殷墟花园庄东地甲骨卜辞中,多次出现一位当时还活着的、称为“丁”的人物,从卜辞内容可以看出其地位甚高。本文主要通过指出这批卜辞中与历组一类占卜同事的一组卜辞,肯定了“丁”就是当时的商王武丁。以“丁”称呼时王武丁,究竟应该如何解释尚待进一步研究。同时,也可以进一步推定这批卜辞的时代,当为武丁晚期而非整理者认为的“武丁前期”。此外,这批卜辞中多次出现的一个整理者隶定作“”的字,应释为“速”,意为“召”、“召请”。旧有殷墟卜辞中一个或释读为“眚”、“软”、“喘”等的字,应释为“” ,读为咳嗽之“嗽”。     

Boiled versus unboiled: a study on Neolithic and contemporary human bones

Bones treated at low temperature do not present major modifications although, macroscopically, boiled bones may be distinguished from unboiled ones as they are smoother, lighter and more transparent. Such observations should correspond to textural modifications at a nanometric level and should depend on boiling time. In this study, contemporary human bones, boiled during various time intervals, were characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and nitrogen adsorption (BET). The results were used to estimate the boiling time in four archaeological samples (Neolithic bones from Malalmuerzo cave, Spain). It is concluded, comparing Neolithic bones to contemporary ones and from the textural characterization at a nanometrical level, that two of the archaeological bones were boiled and that they were boiled for less than 6 hours.
