Who ate the birds: the taphonomy of Sarakenos Cave,Greece

The taphonomic analysis of avian remains from Sarakenos Cave reveals that, contrary to previous suggestions, many bird bones excavated there represent food remains of the Eagle Owls rather than humans. The conclusion is based on the presence of traces of digestion, beak and claw punctures, and indirect evidence that includes relative preservation of particular elements, species composition, the lack of cut marks, and the absence of numerous traces of burning. Specimens with medullary bone and traces of digestion indicate that the owls killed breeding females in spring. Since it is unlikely that owls shared the cave with humans at the same time, it supports the notion based on archeological evidence that human groups did not inhabit it permanently.     

Stone Age exploitation of birds on the island of Gotland,Baltic Sea: a taphonomic study of the avifauna on the Neolithic site of Ajvide

We have conducted a detailed taphonomic study of the avifauna of the Pitted Ware culture site of Ajvide on the Island of Gotland in the Baltic Sea, in order to investigate the fowling patterns and the taphonomic history of the bird remains. We have investigated cultural as well as natural modifications on the bird bones, fragmentation and fracture patterns, and performed a systematic surface modification study. No specific area for the deposition of bird remains or specific bird species was identified. All major anatomical parts of birds are present in the assemblage, but there is a dominance of specimens from the wing elements. Traces of cultural modification were observed on the bones, including cut marks, burning, modification (implements, beads, raw material), and gnawing marks. The bone surface modifications and fracture analysis indicate that the majority of the bird bones at Ajvide did not lie on the soil surface for an extended period of time before being deposited in the soil. Dry fractures increase while fresh fractures decrease towards the upper levels of the stratigraphy, indicating more extensive post‐depositional destruction. This may partly be connected to modern agriculture, but also to later use of the settlement area as a burial ground. The Ajvide assemblage contains a variety of birds living in different biotopes. However, bird hunting was mainly focused on sea birds. Auks and ducks are the most common families in the assemblage. We find it likely that the Ajvide hunters conducted organised hunting expeditions to two nearby islands for the hunting of auks, while it was possible to hunt other birds such as ducks closer to the site. The presence of medullary bone and bones from subadult birds indicates a main hunting season in late spring and early summer. However, comparisons with modern migration patterns indicate that hunting may have occurred throughout the year. Of special palaeozoological interest is the find of gannet (Morus bassanus), which apparently in Neolithic times visited the Baltic area more regularly than today.

Comparative human and deer (Odocoileus virginianus) taphonomy at the Richards site,Ohio

The Richards site is attributed to the Philo phase of the Fort Ancient tradition of the Ohio Valley area. Human skeletal material from the site shows evidence of peri‐ and post‐mortem taphonomic changes, including cut marks, burning and fracturing. Previous analyses have discussed explanations for these changes, including secondary burial, ritual destruction and cannibalism. Researchers have theorised that, allowing for differences in anatomy among species, humans and animals butchered for the same purpose (consumption) will show similar patterns of taphonomic changes associated with butchery. The human remains at the Richards Site were disposed in general midden pits containing mixed cultural debris and faunal remains. White‐tailed deer (Odocoileus virginianus) constitutes approximately 60% of all the faunal bone, indicating that it was a major food resource. To test a cannibalism explanation, a comparative analysis of human‐induced taphonomy in human and deer skeletal remains was performed, using chi‐square and odds ratio tests. If humans were being used as a food resource, the pattern of butchery seen would mirror that of the deer. The analysis described here compares the patterns of treatment and disposal of human and deer skeletal elements at the Richards site, to test whether both species were used as food resources. Similar types of evidence for human‐induced taphonomic changes, including cutting, chopping, burning and breakage, can be seen in both species. However, results indicate that, in general, human remains show much more evidence of perimortem treatment than do deer remains. In fact, the common odds ratio for perimortem treatment in all bones is 3.25, indicating that a human bone is 3.25 times as likely as a deer bone to be affected by burning, cutting or chopping. This probably indicates that perimortem treatment of humans was greater than that necessary simply for butchering for consumption. Copyright © 2005 John Wiley & Sons, Ltd.     

Survival of a multiple skull trauma: the case of an early neolithic individual from the LBK enclosure at Herxheim (Southwest Germany)

The Early Neolithic enclosure of Herxheim yielded the human remains of more than 450 individuals mainly represented by cranial vaults and numerous fractured cranial and postcranial bones. The skulls were shaped post‐mortem into skull caps by intentional separation of the cranial base and facial bones. One of these calottes revealed four ante‐mortem traumatic lesions and additional cut marks.The defects of this individual were analysed in detail to obtain information on the chronology and consequences of the traumata and manipulations and their probable intention. Four marks could be attributed to at least two violent incidents because of their different stages in the healing process. There is no evidence of cranial surgery, but the individual may have received some medical treatment and social care to survive the injuries without complications. The peri‐mortem cut marks and the post‐mortem intentional shaping of the skull cap, however, can be seen as typical for the treatment of the Herxheim dead and cannot be attributed to violent conflicts. The results support the evidence gained from preliminary examinations of the Herxheim human remains and suggest a more complex view of the final phase of the Linear Pottery Culture (LBK) in southwest Germany.

Quantitative micromorphological analyses of cut marks produced by ancient and modern handaxes

In this study, we analyse the three-dimensional micromorphology of cut marks on fossil mammal remains from a ∼0.5 million year old Acheulean butchery site at Boxgrove (West Sussex, southern England), and make comparisons with cut marks inflicted during the experimental butchery of a roe deer (Capreolus caproelus) using a replica handaxe. Morphological attributes of the cut marks were measured using an Alicona imaging microscope, a novel optical technique that generates three-dimensional virtual reconstructions of surface features. The study shows that high-resolution measurements of cut marks can shed light on aspects of butchery techniques, tool use and the behavioural repertoire of Lower Palaeolithic hominins. Differences between the experimental cut marks and those on the Boxgrove large mammal bones suggest variation in the angle of the cuts and greater forces used in the butchery of the larger (rhinoceros-sized) carcasses at Boxgrove. Tool-edge characteristics may account for some of these differences, but the greater robusticity of the Boxgrove hominins (attributed to Homo heidelbergensis) may be a factor in the greater forces indicated by some of the cut marks on the Boxgrove specimens.     

The domestic fowl and other birds from the Roman site of Mons Claudianus,Egypt

At the Roman quarry settlement of Mons Claudianus in the Eastern Desert of Egypt extreme aridity has preserved large amounts of organic matter. Amongst the faunal remains were several hundred bird bones, together with feathers and egg shell. The majority of the bird bones have been identified as domestic fowl Gallus gallus. Other species are rare: they include a few passage migrants and resident species. Finds of spurred tarsometatarsi and bones with medullary deposits indicate that both male and female domestic fowl are represented. It is likely that they were transported to the site from the Nile valley alive; some may have been kept at the settlement. Cut marks suggest that some at least were eaten, but the birds may have been used for different purposes, both secular and ritual. © 1997 John Wiley & Sons, Ltd.     

Cut marks on the Middle Pleistocene elephant carcass of Áridos 2 (Madrid,Spain)

Áridos 1 and Áridos 2 (Madrid, Spain) are two Middle Pleistocene sites belonging to the isotopic stages 9–11. Both places contain partial carcasses of Elephas (Paleoxodon) antiquus associated to Acheulian stone tools. In this work, the taphonomic study of the elephant remains of Áridos 2 is presented. This study has documented several cut marks on different bones, which indicate bulk flesh and viscerae extraction by Middle Pleistocene hominins. Several arguments are provided to support that at least some of the cut marks were made with handaxes, further suggesting that some of these artifacts were butchering tools in this stage of human evolution. Although cut marks on elephant carcasses have been documented at some Middle Pleistocene sites, very few have been published in detail to allow consideration of their status as hominin-imparted marks. By doing so, the present study provides more evidence of large carcass exploitation by hominins during this period.     

Fowling during the Gravettian: the avifauna of Pavlov I, the Czech Republic

This is the first article that describes in detail the bird remains from the Gravettian mega-site Pavlov I in the Czech Republic. More than 1000 bird bones represent at least 19 taxa, of which the most numerous are tetraonids including black grouse (Tetrao tetrix), willow grouse (Lagopus lagopus) and ptarmigan (Lagopus muta), and ravens (Corvus corax). The archaeological and biological contexts indicate that most birds were hunted by people in the vicinity of the site, possibly with the help of knotted nets made from plant fibres. We suggest that ravens were killed while feeding on carcasses and/or food remains that may have been disposed of intentionally, and feathers may have been used for arrow fletching. Human-modified bones indicate that birds were used not only for food but also as raw material for tools and decoration. Although mammals were certainly more important in the subsistence of the Gravettian people, it is clear that birds played a role in their culture. The location of Pavlov I enlarges the explanatory scope of the Broad Spectrum Revolution hypothesis to include higher latitudes north of the Mediterranean.     

Elephants and subsistence. Evidence of the human exploitation of extremely large mammal bones from the Middle Palaeolithic site of PRERESA (Madrid, Spain)

The archaeological site at PRERESA (Madrid, Spain) has been dated to 84 ± 5.6 ka by optically stimulated luminescence (OSL) (MIS 5a). An area 255 m² was excavated and 754 lithic pieces were recovered, as well as a large amount of micro and macro vertebrate remains, including proboscidean bones. The aim of this paper is to outline the results of the taphonomic study of these remains. The identification of cut marks on a number of the bones recovered strengthens the theory that the exploitation of extremely large mammals was more than just a marginal practice before the Upper Palaeolithic. Additionally, the identification of green-bone fractures and percussion marks confirm for the first time, that the bone marrow of these taxa was also consumed. Few other cases of this practice have been identified, firstly because obtaining this substance would not be an easy matter, and secondly because similar nutritional needs can also be met by the consumption of brain matter, which is easier to acquire.     

Raptors in towns: towards an ecological model

A survey was undertaken of the occurrence of bones of raptorial birds in Roman and medieval nucleated settlements in northwestern Europe, and the results were compared with a series of a priori predictions as to which species were the most likely to have colonized such settings. The comparison showed that Haliaeetus albicilla, Buteo buteo and Milvus milvus were recovered relatively frequently, and that these three were amongst the species predicted to be the most successful urban scavengers. It is suggested that Buteo lagopus and Milvus migrans are underrecorded, and that records of Aquila pomarina might be expected in the circum-Baltic region. Accipiter species are inherently unlikely urban birds because of their hunting and feeding behaviour, and the numerous records, especially of Accipiter gentilis are argued to be birds kept for hawking. This would be consistent with the observation that Accipiter spp. are commonly found as whole or partial skeletons. The general agreement of observations with expectations is taken to validate the underlying premise that refuse constituted a major environmental factor in Roman and medieval towns. © 1997 John Wiley & Sons, Ltd.     

Micro-photogrammetric and morphometric differentiation of cut marks on bones using metal knives,quartzite, and flint flakes

In a previous article, we presented an innovative method to analyze cut marks produced with metal tools on animal bones from a metrical and tridimensional perspective (Maté-González et al. 2015). Such analysis developed a low-cost alternative technique to traditional microscopic methods for the tridimensional reconstruction of marks, using their measurements and sections. This article presents the results of an experimental study to test this photogrammetric and morphometric method for differentiating cut marks generated with metal, flint, and quartzite flakes. The results indicate statistically significant differences among cut marks produced by these three types of raw material. These results encourage the application of this method to archeological assemblages in order to establish a link between carcass processing and lithic reduction sequences on different raw materials and also to define the kind of tools used during butchery.     

New Equations for the Size Reconstruction of Sturgeon from Isolated Cranial and Pectoral Girdle Bones

Measurements on cranial and pectoral girdle bones of 56 museum specimens of modern sturgeon (Acipenser sturio and A. oxyrinchus) were used for the establishment of regression equations allowing back‐calculation of size from isolated sturgeon remains. Different curve fittings (power, linear, logarithmic and exponential fit) were modeled to retain the most accurate regression. These were then applied to archaeological sturgeon remains (A. sturio/A. oxyrinchus) from Vlaardingen, a Dutch late Neolithic settlement. The back‐calculated lengths obtained on the archaeological remains all stayed within the known size ranges of the two species and allowed making inferences on the possible place of capture of the fish.

Slicing Cut Marks on Animal Bones: Diagnostics for Identifying Stone Tool Type and Raw Material

Abstract

Butchering implements leave identifying signatures on bones. From these signatures, it is possible to distinguish the different raw materials and types of chipped stone butchering tools. The results of recent experiments enable us to distinguish the different types of raw materials and tools used in the butchering process, in particular those implements that produce slicing cut marks. Three types of chipped stone tools (blades,flakes, and side scrapers) and raw materials (flint, obsidian, and quartzite), as well as issues relevant to lithic production and use were examined and tested. Silicone molds of cut marks produced by each of the instruments were made and subjected to analysis in light optical and scanning electron microscopes under various levels of magnification. The criteria used for distinguishing tool type, raw material, type of production and use characteristics of the respective cutting instruments are presented, as well as a discussion of the application of the experimental results to the Early Bronze Age I site of Afridar, Israel. The data from Afridar indicate that almost all of the butchering marks on animal bones from the site were made by stone tools, in particular haphazardly-made flakes.     

Preservation of bird bones: erosion versus digestion by owls

Surface damage to bird bones from pellets of three species of owls (S. aluco, A. otus and B. bubo) was compared with that of bird bones exposed to weathering and soil corrosion (Záskogo Cave in the Western Balkan Mountains, Bulgaria and Ciemna Cave, southern Poland). Scanning electron microscopy and light microscope examinations indicate that the effects of weathering of bird bones (extensive pitting and flaking away on whole bones, holes with sharp edges, depressions with rough bottoms and sharp edges of breakage) are distinguishable from those of digestion (rounding of hole edges on articular ends and sometimes on shafts, rounding of breakage). However, soil corrosion may produce similar rounding to that of digestion, which may hamper taphonomic interpretations of fossil assemblages. Two stages of weathering in bird bone are distinguished. Generally, the kind of damage done to bird bones is similar to that done to mammalian remains. Taphonomic studies of fossil bird remains should take into account a combination of features, including surface damage, fragmentation and possible chemical alterations of bone tissues. © 1997 John Wiley & Sons, Ltd.     

Analyzing cut marks: lessons from artiodactyl remains in the northwestern United States

Analyses and interpretations of the human behavioral significance of frequencies of cut-marked mammal bones have been ongoing for at least 50 years. Many of these studies focus on determining the so-called “butchering pattern.” Few analysts comment on the tremendous range of variation in frequencies and anatomical distributions of cut marks across multiple assemblages of remains of a taxon. Such variation is evident even when faunal remains are associated with technologically, temporally, and environmentally similar cultures. This kind of variation is illustrated with frequencies of cut marked bone specimens comprising major limb joints of two artiodactyl genera from two sites in the northwestern United States. Three hypotheses are tested. The first and second hypotheses (one per genus) predict that the frequencies of cut-marked remains of a taxon from one site will match those frequencies evident on the remains of the same taxon at the other site. Both hypotheses are falsified. The third hypothesis is that remains of the larger taxon at each site will display more cut marks than the remains of the smaller taxon at each site. This hypothesis is statistically falsified at one site but not the other. Refutation of the hypotheses suggests that well-founded interpretations of frequencies of cut-marked remains may require unique kinds of contextual data.     

Shell tool use by early members of Homo erectus in Sangiran,central Java,Indonesia: cut mark evidence

Sangiran has been known as a source of fossil Homo erectus but is better known for the absence of archaeological tools. Cut mark analysis of Pleistocene mammalian fossils documents 18 cut marks inflicted by tools of thick clamshell flakes on two bovid bones created during butchery at the Pucangan Formation in Sangiran between 1.6 and 1.5 million years ago. These cut marks document the use of the first tools in Sangiran and the oldest evidence of shell tool use in the world.     

The Red Fox (Vulpes vulpes) as an Accumulator of Bones in Cave‐like Environments

Identifying the behavioural patterns of bone collecting animals is a crucial aspect of taphonomic studies. Although many studies have established criteria for identifying animal‐collected or animal‐modified bones, very few papers describe the distinguishing features of fox‐made bone assemblages. The bone assemblage collected in an inactive underground stone mine in Potok‐Senderki (Poland) is diagnostic of a red fox (Vulpes vulpes) den. This site provides an ideal opportunity to develop an understanding of the bone collecting behaviour of red foxes in cave‐like environments. This study showed that bones collected by red foxes are concentrated in clusters. The bones represent a broad spectrum of local fox prey species, with most bones showing the marks of gnawing. Each cluster may contain from <10 to >100 bones. Furthermore, the long axes of the bones in clusters frequently show specific orientation. The analysis of bones at this site might make an important contribution towards the establishment of baseline criteria for the identification and evaluation of fox‐accumulated bone assemblages.

Trace fossils on penguin bones from the Miocene of Chubut,southern Argentina

Several traces of biological interaction were found on penguin bones from the basal levels (Aquitanian) of the Miocene Gaiman Formation in the lower Chubut valley of the Provincia del Chubut, Argentina. The fossil-bearing beds were deposited in littoral to sublittoral environments within sediments of mostly pyroclastic origin. We interpret many traces to have been produced by predators and/or scavengers while the penguins were still in a breeding area. Many bones show cracking marks due to aerial exposure. The material is disarticulated as is usual in recent breeding areas. Potential predators were coeval terrestrial mammals, most probably marsupial carnivores. After a marine transgression, these bones were buried or exposed on the sea bottom where they could be colonized by algae, sponges, cnidarians, and other benthic organisms. We identified sponge borings in several bones. Other traces are interpreted to have been produced by echinoderms feeding on sponges or algae. No evidence of other invertebrate predators such as muricid or naticid gastropods, or decapods was found. Finally, other traces appear to have been generated by shark and possibly teleostean vertebrates feeding on epibionts. One coracoid is interpreted to have been marked by a shark that is common in the Gaiman Formation, the carcharhiniform Galeocerdo aduncus. From an ethological (Seilacherian) classification, traces on bones from the Gaiman Formation include Domichnia (sponge perforations), Praedichnia (terrestrial marsupials, sharks, teleosteans) and Pasichnia (echinoderms). Remarkably, remains of marine organisms with skeletons made of calcium carbonate are very poorly preserved in the Gaiman Formation. Only large oysters, sparse shell fragments, skeletal moulds, and bioturbation is evident. The fossil assemblage is mainly composed of phosphatic (e.g. teeth, bones, crustacean parts) and siliceous (sponge spicules, diatoms) remains.     

The molecular palaeoecology of geese: identification of archaeological goose remains using ancient DNA analysis

The remains of six species of geese are commonly recovered from archaeological sites in Britain dating from the Saxon and later periods. However, identification of this material to species level is hampered by a lack of morphological variation and a large overlap in size. To address this issue we obtained DNA sequence data for a section of the mitochondrial cytochrome b gene from modern samples of each species, and successfully identified several DNA markers for Branta species. No markers were found within the cytochrome b gene for the genus Anser. Ancient DNA techniques were then used to recover DNA from goose bones excavated from two archaeological sites. The DNA sequences enabled identification of Barnacle goose (Branta leucopsis) from one site and confirmed the presence of Anser species at another. © 1998 John Wiley & Sons, Ltd.     

Prehistoric Butchery and Consumption of Birds in the Kingdom of Tonga,South Pacific

We evaluate the preservational attributes (element frequency, breakage, burning, cut-marks, rodent gnawing, and age) of ca. 500 bird bones from three prehistoric archaeological sites on the Polynesian islands of Foa and Lifuka in the Ha‘apai Group, Kingdom of Tonga. Two of the sites lie in calcareous beach sands whereas the third is the refuse infilling of a well. Although differing in age, all three sites are unequivocally cultural in origin, as evidenced by rich artifact assemblages and various sedimentological features (pits, hearths, etc.) that reflect human activities. The sites also contain bones from a diverse assemblage of marine fish, marine and terrestrial reptiles (sea turtles, iguanas), and terrestrial mammals (fruit bats, rats, pigs, dogs). We find no evidence for deposition of bones (bird or otherwise) in these Tongan sites by non-human agents. This is expected given that we are unaware of any non-human species or geological process that would concentrate the bones of fishes, reptiles, birds, and mammals on a beach ridge or in a well in Tonga. This is especially the case since the species range from very small to very large, and represent marine, fresh water, coastal, and forested habitats. Nevertheless, clear evidence of cultural involvement cannot be discerned on most individual bones, whether bird or non-bird. Furthermore, most taphonomic attributes (element frequency, breakage, burning, and cut-marks) of bones of a domesticated species (the chicken, Gallus gallus) resemble those found on bones of indigenous landbirds. We believe that all bones in any zooarchaeological assemblage should be evaluated carefully to determine who or what was responsible for their deposition. We see no reason, however, why bird bones should be held to some standard higher than those applied to the bones of other taxa, as some have suggested.
