Studies on Amerindian dogs: Taxonomic analysis of canid crania from the Northern Plains

Archaeological investigation of the economic role of domestic versus wild canids among late prehistoric and historic villagers in the Northern Plains has long been hindered by difficulties in reliably distinguishing between remains of different species, especially dogs (Canis familiaris) and wolves (Canis lupus). Taxonomic confusion is the result of deliberate human selection for large, strong dogs for use as draft animals, and occasional but probably consistent hybridization between dogs and wolves. Discriminant analysis is used to help identify 33 archaeological canid crania from the Northern Plains, many of which are taxonomically confusing. Reference samples for classification of these specimens consist of six groups of modern or archaeological dog, wolf and coyote (Canis latrans) crania from North America. Thirteen measurements are used. Analysis indicates that, relative to wolves, the dogs tend to have proportionally wide posterior cranial vaults, short snouts and palates, steeply rising foreheads, and small teeth. Although convincing evidence for dog—wolf hybrid specimens from recent Plains archaeological contexts is lacking, the identification of such specimens probably has little practical significance with regard to canid domestication in general. Compared to dogs, a greater proportion of specimens identified as wolves exhibit evidence of butchering.     

Neolithic dogs: A reappraisal based on evidence from the remains of a large canid deposited in a ritual feature

A canid skull and mandible, dated to the late neolithic, produced a series of measurements which indicate an animal significantly larger than any dog recovered from this period. The skull showed evidence of healed trauma with associated asymmetry. Metrical and morphological criteria have been applied to identify the remains as those of wolf Canis lupus, and the results of these tests are inconclusive. The possibility that the remains are of a large dog, Canis familiaris, is discussed, together with the implications that this may have for the archaeological consideration of this species.     

Osteometric Variation in Domestic Dogs (Canis familiaris) from the Kodiak Archipelago,Alaska

The research presented here is a re‐examination of domestic dog (Canis familiaris) remains from the Uyak site on Kodiak Island, Alaska. Previous analyses suggest there were two breeds of dog represented in this archaeological assemblage, primarily on the basis of dog cranial size. Here, we use a series of metric and nonmetric traits to test the argument that these ‘breeds’ actually represent a population of male and female dogs. On the basis of the results presented here, we argue the metric and nonmetric data produced by this study suggest that the dogs in this sample are male and female specimens, rather than two distinct breeds. The Uyak assemblage is the largest collection of domestic dog from Kodiak, and these results have the potential to contribute to our understanding of human–dog relationships in the archipelago.

Palaeolithic dog skulls at the Gravettian P?edmostí site, the Czech Republic

Whether or not the wolf was domesticated during the early Upper Palaeolithic remains a controversial issue. We carried out detailed analyses of the skull material from the Gravettian P?edmostí site, Czech Republic, to investigate the issue. Three complete skulls from P?edmostí were identified as Palaeolithic dogs, characterized by short skull lengths, short snouts, and wide palates and braincases relative to wolves. One complete skull could be assigned to the group of Pleistocene wolves. Three other skulls could not be assigned to a reference group; these might be remains from hybrids or captive wolves. Modifications by humans of the skull and canine remains from the large canids of P?edmostí indicate a specific relationship between humans and large canids.     

Disease: A Hitherto Unexplored Constraint on the Spread of Dogs (<Emphasis Type="Italic">Canis lupus familiaris</Emphasis>) in Pre-Columbian South America

Although debate continues, there is agreement that dogs (Canis lupus familiaris) were first domesticated in Eurasia, spreading from there to other parts of the world. However, while that expansion already extended as far as Europe, China, and North America by the early Holocene, dogs spread into (and south of) the tropics only much later. In South America, for example, the earliest well-attested instances of their presence do not reach back much beyond 3000 cal. BC, and dogs were still absent from large parts of the continent—Amazonia, the Gran Chaco, and much of the Southern Cone—at European contact. Previous explanations for these patterns have focused on cultural choice, the unsuitability of dogs for hunting certain kinds of tropical forest prey, and otherwise unspecified environmental hazards, while acknowledging that Neotropical lowland forests witness high rates of canine mortality. Building on previous work in sub-Saharan Africa (Mitchell in Archaeol Res Afr 50:92–135, 2015), and noting that the dog’s closest relatives, the grey wolf (C. lupus) and the coyote (C. latrans), were likewise absent from South and most of Central America in pre-Columbian times, this paper explores instead the possibility that infectious disease constrained the spread of dogs into Neotropical environments. Four diseases are considered, all likely to be native and/or endemic to South America: canine distemper, canine trypanosomiasis, canine rangeliosis, and canine visceral leishmaniasis caused by infection with Leishmania amazonensis and L. colombiensis. The paper concludes by suggesting ways in which the hypothesis that disease constrained the expansion of dogs into South America can be developed further.     

Occipital perforations in a late neolithic probable aurochs (Bos primigenius bojanus) cranium from Letchworth,Hertfordshire, UK

An example of ante‐mortem occipital perforations in the cranium of a probable aurochs (Bos primigenius) cow from a late Neolithic archaeological site at Letchworth, Hertfordshire is presented. This is the second reported occurrence thus far of cranial perforations in a wild bovid and lends support to a congenital cause of the condition in archaeological domestic cattle skulls.

Canidae volume bone mineral density values: an application to sites in western Canada

We present volume bone mineral density values from five different canid species: domestic dog (Canis familiaris), wolf (Canis lupus), coyote (Canis latrans), red fox (Vulpes vulpes) and swift fox (Vulpes velox). We use these density values to investigate Canidae remains from four archaeological sites in western Canada and show the importance of explicitly stating assumptions made about the original composition of the deposited faunal assemblage as this influences whether correlations are found between density and percent survivorship (%MAU).     

Studies on Amerindian dogs, 3: Prehistoric wolf/dog hybrids from the northwestern plains

Discriminant function analysis is an invaluable statistical tool for the taxonomic identification of hybrids between various extant species of Canis in the eastern United States. This technique has recently been applied to the taxonomic identification of canid skulls from several Wyoming archaeological sites. Analysis indicates most canid remains, originally identified as wolf (Canis lupus), to be wolf/dog hybrids exhibiting constant and continual backbreeding to the local wolf populations. The spatial and temporal extent of the form is discussed.     

Body Mass Estimates in Dogs and North American Gray Wolves Using Limb Element Dimensions

Body mass is a key biometric that is useful in interpreting many aspects of an animal's life history. For many species, including dogs and wolves, methods for estimating body mass are not well developed. This paper assesses the utility of using limb dimensions to predict body mass in dogs and North American wolves. Regression analyses are utilized here to explore the correlations between limb dimensions and body masses of modern dogs and wolves, all of known body mass at death. These analyses reveal that a number of limb end dimensions are correlated with body mass in both dogs and wolves. Regression formulae generated through the analyses appear to allow body masses to be predicted with relatively small margins of error, often less than 10%. Formulae are calculated for groups with and without juveniles. In some cases, the dimensions of the juvenile specimens plot distinctly from those of adults, indicating that regression formulae specifically for juvenile canids may be needed. The strength of the limb dimension correlations is then compared with that of regression formulae for dog and wolf cranio‐mandibular dimensions. For the dogs, the cranio‐mandibular dimensions appear to slightly out‐perform the limb element dimensions in predicting body mass. The wolf limb dimensions, however, always appear to provide better predictions of body mass than do the skull dimensions. The newly developed regression formulae are applied to several Middle Holocene dog skeletons from Siberia for which previous body mass estimates are available, the latter based on cranial dimensions. These two sets of estimates are then compared. The overall results of our study indicate the need for further research, particularly with larger sample sizes, including more juvenile specimens. We also argue that work on body size estimation in single dog breeds may be warranted in some cases. Copyright © 2016 John Wiley & Sons, Ltd.     

Wild or domesticated? An ancient DNA approach to canid species identification in South Africa's Western Cape Province

The fragmentary remains typical of archaeological fauna can prove impossible to identify when confronted with closely related sympatric species. In southern Africa domesticated dogs (Canis familiaris) and black-backed jackals (Canis mesomelas) pose just such a problem, rendering difficult an accurate assessment of the timing of arrival of domesticated dogs in the region. Contextual evidence has suggested that canid remains from four Later Stone Age archaeological sites were likely to be domesticated dogs rather than jackals, and were subjected to ancient DNA analyses to determine species. Every tested specimen proved to derive from black-backed jackals. These data provide not only an unexpected window on southern African prehistory, but also highlight the value in applying ancient DNA techniques to archaeological species identification.     

The role of canids in ritual and domestic contexts: new ancient DNA insights from complex hunter–gatherer sites in prehistoric Central California

This study explores the interrelationship between the genus Canis and hunter–gatherers through a case study of prehistoric Native Americans in the San Francisco Bay-Sacramento Delta area. A distinctive aspect of the region's prehistoric record is the interment of canids, variously classified as coyotes, dogs, and wolves. Since these species are difficult to distinguish based solely on morphology, ancient DNA analysis was employed to distinguish species. The DNA study results, the first on canids from archaeological sites in California, are entirely represented by domesticated dogs (including both interments and disarticulated samples from midden deposits). These results, buttressed by stable isotope analyses, provide new insight into the complex interrelationship between humans and canids in both ritual and prosaic contexts, and reveal a more prominent role for dogs than previously envisioned.     

Stable isotope analysis of dog,fox, and human diets at a Late Holocene Chumash village (CA-SRI-2) on Santa Rosa Island,California

Stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope analyses of dog (Canis familiaris), island fox (Urocyon littoralis), and human bone collagen from CA-SRI-2 (AD 130–1830) on Santa Rosa Island, California provide a proxy of diet and the relationships between humans and these animals. Carbon isotopic signatures indicate that Native Americans and their dogs at CA-SRI-2 subsisted almost exclusively on marine resources, while the island fox ate primarily terrestrial foods. Nitrogen isotopes and archaeofaunal remains indicate that humans and dogs also ate higher trophic level foods, including finfishes, marine mammals, and seabirds with smaller amounts of shellfish. The CA-SRI-2 island foxes appear to have eaten higher amounts of terrestrial foods, similar to the diets observed in modern fox populations. These data generally confirm the commensal relationship assumed to exist between domesticated dogs and people, but the carbon isotopic composition of dogs is enriched ∼2‰ compared to humans. We hypothesize that the difference in carbon isotopes between dogs and humans may have resulted from a higher consumption of C3 plants with lower δ¹³C values by humans, or less likely from the ingestion by dogs of significant amounts of bone collagen, which is enriched by ∼4‰ over associated muscle.     

Early Domestic Dogs in North America and Their Origins

Abstract

Archaeologists have contributed much new information relating to types of domestic dogs that were present in pre-Columbian North America. Questions yet to be answered are: Where did the basal stock for these early Western Hemisphere dogs originate? What were they like morphologically? Some reported early canids, particularly those from late Pleistocene deposits, are subject to question as to their domestic role. These and related problems are discussed.     

A double dog burial from San Nicolas Island, California, USA: osteology, context, and significance

Recent archaeological excavations on San Nicolas Island, located off the coast of southern California, revealed the remains of a double dog burial interred sometime during the 13th and 14th centuries. Two carefully laid to rest and possibly sacrificed juvenile, female domestic dogs (Canis familiaris) between the ages of 1 and 6 months were found within a Native American village. Digestive tract residues include burned and unburned fish and marine mammal bone that suggest scavenging behavior or direct feeding by humans. Breed classifications place it between the Short-Nosed Indian dog and the Plains-Indian dog, likely representing a cross between those and other varieties of North American dogs. Comparisons with other dog burials from archaeological sites across southern California suggest commonalities and possible cultural linkages.     

On some remains of dog (Canis familiaris) from the Mesolithic shell-middens of Muge,Portugal

The dog has a unique relationship with humans. This is demonstrated by the number of breeds that exist today and the important role that dogs play in human society. The archaeological record also shows that this relationship began long ago when groups of hunter–gatherers domesticated the wolf probably in several parts of the globe.     

Carnivores and their prey in the Wezmeh Cave (Kermanshah,Iran): a Late Pleistocene refuge in the Zagros

Wezmeh Cave is located on the northeastern edge of the Islamabad plain, a high intermontane valley in the western‐central Zagros. In 1999 a disturbed but large faunal assemblage was recovered from this site. The abundant and extremely diverse faunal spectra present at Wezmeh Cave has highlighted the importance of this assemblage. Carnivore remains constitute the bulk of the assemblage; red fox (Vulpes vulpes) has the highest number of identified specimens followed by spotted hyena (Crocuta crocuta), brown bear (Ursus arctos), wolf (Canis lupus), felids (lion, leopard, lynx/caracal and wildcat), mustelids (badger, polecat, marten) and viverrids (mongoose). Artiodactyls (bovid, cervid, suid), equids, rhinoceros (Dicerorhinus sp.) and small animals (Cape hare, porcupine, tortoise, snake, birds) are also present. According to U‐series dating, the site was occupied from around 70 ka BP through to sub‐recent periods by carnivores. Amongst this rich assemblage, a human fossil tooth was also found and dated by non‐invasive spectrometry gamma dating to 20–25 ka BP. A preliminary zooarchaeological and taphonomic study shows that Wezmeh Cave was used by multiple carnivore species, a unique phenomenon in the Zagros Mountains in particular and southwest Asia in general.

A case of cranial trepanation in a Roman necropolis (Cassino,Italy, 3rd century BC)

The aim of this study was to investigate an individual from a Cassino necropolis of the 3^rd century BC. The inhumation shows a rectangular wound between the sagittal and lambdoid sutures of the cranium. Furthermore a series of pathological traces on the post‐cranial skeleton are present. The trepanation of the skull seems intentional: probably a healed surgical procedure to treat a sword wound. Copyright © 2007 John Wiley & Sons, Ltd.     

Raising Practices of Neolithic Livestock Evidenced by Stable Isotope Analysis in the Wei River Valley,North China

Although a patchwork of projects shows a process of agriculture intensification in North China during the Neolithic, the impact of cereal farming on animal husbandry and their mutual interaction remain cloudy. This study reports bone collagen δ¹³C and δ¹⁵N of humans and animals from Wayaogou (ca 6.5–6.0 kyrs bp ) and Dongying (ca 5.9–5.6 kyrs bp , 4.6–4.0 kyrs bp ) to explore temporal trend of livestock raising and particularly the importance of millet fodder to stock raising practices in the Wei River valley, North China. The isotopic evidence overall shows that millet products increased in human and domestic animal diets during the mentioned chronological span. δ¹³C values of pigs and dogs at Dongying are higher than those at Wayaogou, implying that the importance of millet nutrients increased to animal husbandry diachronically. Interestingly, δ¹³C results of domestic cattle of Dongying late phase (−14.1 ± 1.1‰, N = 5) are more enriched than Wayaogou wild Bos (−17.8 ± 0.3‰, N = 3), indicating that millet fodder had taken a significant place in early cattle husbandry. Besides, differences between Bos species of the two periods also imply that δ¹³C values of bone collagen constitute a potential indicator for tracing the origin of cattle husbandry in North China. In addition, domestic sheep at Dongying produced similar isotope data to wild ovicaprid at Wayaogou, suggesting that they possibly had grazed for the most in grassland and therefore experienced a different lifestyle from cattle.

A taphonomic study of the African wild dog (Lycaon pictus)

Carnivore taphonomy has been traditionally used for the interpretation of archaeological sites in order to discriminate human-generated or modified from non-anthropic bone assemblages. In most of this actualistic research, the focus has mainly been placed on hyenas and felids, neglecting other carnivores. This paper analyzes the taphonomic impact of the African wild dog (Lycaon pictus) on equid bones and compares it with the bone modification patterns produced by other canids, such as wolves (Canis lupus) in order to compare medium-/large-sized canid variability on bone modification patterns and elaborate a referential framework which could be feasibly applied to the zooarchaeological record to detect canid intervention on archaeological assemblages in the past.     

Eneolithic Cattle Burials from Aljmaš‐Podunavlje and Osijek‐Retfala,Croatia

Two single bovine burials and one mixed animal burial (containing bovine and canid skeletal remains) have been unearthed at two Baden culture sites, Aljmaš‐Podunavlje and Osijek‐Retfala located in Eastern Croatia. Zooarchaeological analysis attributed the faunal remains to domesticated cattle (Bos taurus) and in one case a dog (Canis familiaris). Almost complete and articulated skeletons of subadult or adult cows were found in all three examined features, while pit 59/60 from Aljmaš also contained a skull belonging to an adult‐domesticated cattle and a skeleton of a very young dog, 2–3 months old. All of the skeletons are well preserved and display no evidence of carcass processing indicating that the animals were buried intentionally. Consideration of the positions in which these animals were interred and their relationship with nearby deposits enables discussion of potential animal burial strategies and possible connections with certain ritual practices in which cows and in one case a dog played important roles. The described burials represent the southernmost known distribution of the rite discussed. Copyright © 2015 John Wiley & Sons, Ltd.
