RESUMO

The peopling of the Americas and human interaction with the Pleistocene megafauna in South America remain hotly debated. The Santa Elina rock shelter in Central Brazil shows evidence of successive human settlements from around the last glacial maximum (LGM) to the Early Holocene. Two Pleistocene archaeological layers include rich lithic industry associated with remains of the extinct giant ground sloth Glossotherium phoenesis. The remains include thousands of osteoderms (i.e. dermal bones), three of which were human-modified. In this study, we perform a traceological analysis of these artefacts by optical microscopy, non-destructive scanning electron microscopy, UV/visible photoluminescence and synchrotron-based microtomography. We also describe the spatial association between the giant sloth bone remains and stone tools and provide a Bayesian age model that confirms the timing of this association in two time horizons of the Pleistocene in Santa Elina. The conclusion from our traceological study is that the three giant sloth osteoderms were intentionally modified into artefacts before fossilization of the bones. This provides additional evidence for the contemporaneity of humans and megafauna, and for the human manufacturing of personal artefacts on bone remains of ground sloths, around the LGM in Central Brazil.

RESUMO

OBJECTIVE: This article evaluates the prevalence of lesions in a modern osteological collection of guanacos (Lama guanicoe) and discusses the potential of paleopathological data to assess human intervention and environmental stress. MATERIALS: A modern osteological collection of guanacos (NISP = 862) from north-western Córdoba, Central Argentina. METHODS: The prevalence of pathological specimens per skeletal element and the pathological index (Bartosiewicz et al., 1997) was used. The prevalence of arthropathies, trauma and infections was quantified. Additionally, thorn lesions in the autopodium were recorded. RESULTS: 11.03 % of the specimens presented pathological changes and the mean pathological index was 0.01. Degenerative lesions were the most prevalent type (10.34 %), followed by traumatic (0.81 %) and infectious pathologies (0.12 %). Thorn lesions (2.55 %) were recorded especially in metapodials. CONCLUSIONS: Guanacos are exposed to the development of degenerative lesions, mainly in the autopodium and vertebrae. These lesions are probably common in camelids and should not be used to argue human management. Traumatic and infectious lesions are less frequent. SIGNIFICANCE: This work provides baseline information for the paleopathological study of South American camelids and contributes to the characterization of a regionally endangered species. LIMITATIONS: The nature of the faunal assemblage did not allow for direct correlations between pathologies and individual variables such as sex or age. SUGGESTIONS FOR FURTHER RESEARCH: The comparison of our results with other wild and domesticated modern populations would be valuable to expand the baseline information for paleopathological studies. The use of quantitative methods is encouraged for future comparative and diachronic studies.

RESUMO

South Brazil's archaeological coastal sites (shellmounds and middens) show a diverse collection of shark faunal remains, some of which belong to species considered rare nowadays for the region. However, shark archaeological remains identification in this region has been historically insufficient and prone to mistakes. This study identified shark fauna and estimated body size (total length) present at two archaeological sites: Rio do Meio (1220-977 Cal B.P.) and Enseada II (4286-3783 Cal B.P.), located in Santa Catarina, South of Brazil. Here, 1600 teeth and 3588 vertebrae were analysed and identified. We showed higher historical shark species richness than previously reported for South Brazil in historical and archaeological studies. In total, we identified at least 15 species of sharks (11 species and four identifications at the genus level). The presence of juvenile shark remains adds to the evidence of pre-colonial fishing impacts in local shark populations. The consistent recovery of adults and juveniles of Carcharias taurus points to a possible nursery area on the mouth of Babitonga bay. The high teeth frequency (43%) of C. taurus suggests the South Brazil coastline was once home to abundant populations of this critically endangered species. Furthermore, we discuss the presence of rare species nowadays, suggesting a possible historical residency for adult populations of Carcharodon carcharias based on the presence of juveniles and young-of-the-year on archaeological sites. The occurrence of Negaprion brevirostris, a tropical species, might have been facilitated by ocean current variations.

RESUMO

In the Greater Antilles, certain animal taxa that have long been theorized to have been managed by indigenous peoples prior to AD1492, the main candidates being a group of endemic caviomorph rodents known as hutias (Capromyinae). This isotopic study investigates the paleodiets of several species of endemic rodents from three late precolonial sites in the northern Dominican Republic: El Flaco (cal. ad 990-1452), El Carril (cal. ad 1030-1262), and La Entrada (cal. ad 840-900) to assess whether human influence over animal diets can be determined. We examined bone collagen carbon (δ13Cco) and nitrogen (δ15N) and tooth enamel carbon (δ13Cen) isotope values of three species of hutias, Isolobodon portoricensis, Isolobodon montanus, and Plagiodontia aedium, alongside edible rat (Brotomys sp.), and domestic guinea pig (Cavia porcellus). To estimate dietary source contributions, we employed a Bayesian dietary mixing model (FRUITS v.3.0) and ran three different permutations to assess the relative contributions of C3 or C4/CAM plants. The addition of an extra 79 wild C3 and 40 wild C4/CAM plant species' isotope values from published sources to an established isotopic foodweb for the Caribbean region enabled us to discriminate between wild and domestic C3 and C4/CAM plant food sources in two of these models. Our results provide evidence of the significant consumption of domestic C4/CAM plants by some animals. This likely represents maize (Zea mays) consumption, which is known to have been ubiquitously cultivated by indigenous peoples in the region. This is particularly the case for I. portoricensis, as FRUITS modeling suggests that a few individuals consumed C4/CAM plants well beyond their expected natural diets as determined from feeding studies of extant hutia species. This may indicate human influence over endemic rodent diets due to niche construction activities such as horticultural practices and may reflect either opportunistic feeding on human produce or the purposeful supplementation of hutia diets by humans.

RESUMO

Mirinaba cadeadensis Lange de Morretes, 1952 is restricted to the Paraná state, and found at the municipalities of Morretes, São José dos Pinhais, Paranaguá, Matinhos, and Guaratuba, associated to the Serra do Mar mountains. In this paper, we report the first record of this species in an anthropogenic shell mound. Two shells of M. cadeadensis were located in the internal stratigraphic layers of the Boguaçu shell mound. This is also the first shell mound record for Mirinaba.

RESUMO

The Lesser Antillean island chain in the eastern Caribbean formerly supported a diverse rodent fauna including multiple endemic genera of oryzomyine rice rats. The Caribbean rice rats are now all extinct, with most island populations known only from Holocene palaeontological and zooarchaeological material and with many remaining taxonomically undescribed. Rice rat material is reported from several pre-Columbian Ceramic Age (late Holocene) archaeological sites on the Grenada Bank, including sites on Grenada and Carriacou, but the taxonomic identity and diversity of the Grenada Bank rice rats has remained uncertain. We provide a morphology-based description of rice rats from Grenada and Carriacou, and analyze their phylogenetic and biogeographical affinities to other Caribbean and mainland Neotropical oryzomyines. We recognize two taxa from the Grenada Bank: we describe the new species Megalomys camerhogne from Pearls (Grenada), representing the largest-bodied member of the extinct endemic Caribbean genus Megalomys, and we refer smaller-bodied oryzomyine material from Pearls and Sabazan (Carriacou) to the widespread extant Neotropical species Zygodontomys brevicauda. Body size variation within Megalomys correlates with island bank area and might thus reflect historical rather than modern biogeography. Zygodontomys specimens from the Grenada Bank fall within the upper end of size variation in extant populations and may constitute an example of 'island gigantism', but it is possible that occurrence of this widespread species on the Grenada Bank might reflect prehistoric human-mediated translocation. We predict further endemic Caribbean rice rat taxa remain to be discovered, including a possible species of Megalomys on the neighbouring island of St. Vincent.

RESUMO

Raw isotope data of collagen (δ13Ccollagen and δ15Ncollagen) and carbonate (δ13Ccarbonate and δ18Ocarbonate) of bone, enamel, and dentine of 101 faunal samples from Parita Bay, Panama are presented. These samples were taken from four archeological sites that span a long termporal range beginning with early hamlet agriculture period marked by the introduction of agricultre (circa 6000 BCE), and extending into the time of Spanish contact (1521 CE). The collection represents twelve faunal species of secondary browsers (deer), potentially captive or habituated birds (waterfowl, parrots, guan, among others), and carnivores (ocelot and domesticated dog). One modern deer specimen was also taken to link archeological baselines with known modern environmental data. This data complements our argument, presented in the article "Domesticated landscapes of the Neotropics: Isotope signatures of human-animal relationships in pre-Columbian Panama" [1], that stable isotope analysis can be a useful proxy to document degrees to which human-plant/animal co-habitation has created anthropogenic ecosystems in the Neotropics.

RESUMO

Fish skeletal remains recovered from two archaeological sites dated in the Middle Holocene of Tierra del Fuego (Argentina) were analysed to describe habitat use patterns by hake in the past and predict changes in a warmer world. Mitochondrial DNA was successfully extracted and amplified from 42 out of 45 first vertebra from ancient hake and phylogenetic analysis assigned all haplotypes to Argentine hake (Merluccius hubbsi). According to osteometry, the Argentine hake recovered from the archaeological site were likely adults ranging 37.2-58.1 cm in standard length. C and N stable isotope analysis showed that currently Argentine hake use foraging grounds deeper than those of Patagonian blenny and pink cusk-eel. Argentine hake, however, had a much broader isotopic niche during the Middle Holocene, when a large part of the population foraged much shallower than contemporary pink cusk-eel. The overall evidence suggests the presence of large numbers of Argentine hake onshore Tierra del Fuego during the Middle Holocene, which allowed exploitation by hunter-gatherer-fisher groups devoid of fishing technology. Interestingly, average SST off Tierra del Fuego during the Middle Holocene was higher than currently (11 °C vs 7 °C) and matched SST in the current southernmost onshore spawning aggregations, at latitude 47 °S. This indicates that increasing SST resulting from global warming will likely result into an increased abundance of adult Argentine hake onshore Tierra del Fuego, as during the Middle Holocene. Furthermore, stable isotope ratios from mollusc shells confirmed a much higher marine primary productivity during the Middle Holocene off Tierra del Fuego.

RESUMO

Recently, Pareja et al. (Primates, 61:159-168,  https://doi.org/10.1007/s10329-019-00778-1 2020) published a report suggesting that the monkeys represented by Minoans in Room 6 of Building Complex Beta at Akrotiri, Thera (present-day Greece) allegedly represented Hanuman or gray langurs (Semnopithecus spp.). This conjecture was based only on the posture of the tail, as it might be reminiscent of those observed in these Asian monkeys. In order to examine this hypothesis, we performed a thorough analysis of tail postures in both langurs and vervet monkeys (Chlorocebus spp.), a detailed description of body and facial characteristics of the Minoan painted monkeys, and an exhaustive review of the current evidence regarding Minoan archeoprimatological frescos and portable objects as well as proposed cultural and trading contacts between the Bronze Age Aegean, Egypt, the Levant, Near East, and the Indus River Valley. Our findings show that their assumption is unfounded and that the monkeys depicted on the walls of the referred fresco, as well as others related frescoes from Thera and Crete, are of African origin and more specifically belong to Chlorocebus spp. and Papio spp. In all cases, hopefully Pareja et al. (2020) and this reply will serve to stimulate further archeoprimatological studies.

RESUMO

This study uses a multiisotope (carbon, nitrogen, oxygen, and strontium) approach to examine early animal management in the Maya region. An analysis of faunal specimens across almost 2,000 years (1000 BC to AD 950) at the site of Ceibal, Guatemala, reveals the earliest evidence for live-traded dogs and possible captive-reared taxa in the Americas. These animals may have been procured for ceremonial functions based on their location in the monumental site core, suggesting that animal management and trade began in the Maya area to promote special events, activities that were critical in the development of state society. Isotopic evidence for animal captivity at Ceibal reveals that animal management played a greater role in Maya communities than previously believed.

RESUMO

Stable isotope ratios of C and N in the bone tissue of three different skeletal elements (angular, cleithrum and vertebra) of three fish species from different evolutionary lineages (Clupeiformes, Atheriniformes and Notothenioidei) were determined before (δ13 Cbulk and δ15 Nbulk ) and after demineralization and delipidation (δ13 Cdml and δ15 Ndml ). One of the species had cellular bone and the other two had acellular bone. Results revealed that δ15 N and δ13 C values from different skeletal elements were interchangeable in species with acellular bone, but caution was needed in species with cellular bone, as δ15 N values varied among skeletal elements. Furthermore, δ15 Nbulk values were significantly lower than δ15 Ndml values in the three species, thus suggesting that they are not comparable. This difference is probably because δ15 Nbulk refers to total bone protein and δ15 Ndml to collagen only.

RESUMO

Abstract Middens are archaeological sites dating between 8,000 and 1,000 years before present and are commonly found on the Brazilian coast. Data were collected from 68 middens allowing an inventory of 142 fish species, most of them recorded in no more than five sites. Conversely, Micropogonias furnieri and Pogonias cromis had the highest frequencies of occurrence. The biogeographic, ecological and economic data showed that most of the identified fish are widely distributed in the Western Atlantic (59.72%) and inhabit estuarine environments (53.99%), while most species have a demersal habit (35.92%) and exhibit oceanic migratory behaviour (28.87%). Lastly, the surveyed fish are predominantly carnivorous (72.54%) with some commercial value (96.48%). Chi-squared tests comparing midden inventory and current ichthyofauna checklists failed to show significant differences between them (p > 0.99). Thus, the results indicate that zoo-archaeological fish remains are key evidence of Holocene biodiversity and may help the establishment of more complete baselines.

Resumo Sambaquis são sítios arqueológicos, datando entre 8,000 e 1,000 anos antes do presente, encontrados na costa brasileira. Neste trabalho, dados ictiológicos referentes a 68 sambaquis da costa Sudeste do Brasil foram compilados e construído um inventário de referência no qual constam 142 espécies, a maioria das quais com registro em não mais que cinco sítios. Por outro lado, as espécies Micropogonias furnieri e Pogonias cromis apresentaram alta frequência de ocorrência nos sambaquis. Os dados biogeográficos, ecológicos e econômicos mostraram que a maioria das espécies registradas nos sambaquis são de ampla distribuição no Atlântico Ocidental (59.72%), habitam ambientes estuarinos (53.99%), tem um hábito demersal (35.92%) e comportamento oceânico migratório (28.87%). A maioria dos registros diz respeito a peixes carnívoros (72.54%) e com algum valor comercial (96.48%). A comparação da lista de ictiofauna registrada para os sambaquis com uma lista construída com base em inventários atuais de peixes para mesma região não mostrou diferenças significativas (teste de qui-quadrado, p> 0.99). Dessa forma, os resultados apresentados indicam que os vestígios de ictiofauna encontrados em sambaquis constituem uma amostra relevante da biodiversidade do Holoceno podendo ser muito úteis na construção de inventários de referências mais completos da fauna ictiológica da costa brasileira.

RESUMO

Three camelid metapodials with polydactyly (additional digits) were found at the Wari culture archaeological site (dated to the Middle Horizon) of Castillo de Huarmey. The anomalous bones were excavated among numerous remains, and presumably represent animals that were sacrificed within the principal mortuary mausoleum. The bones derive from at least two individuals. The etiology of the deformities remains unknown, but the most probable causes include low genetic diversity in the herd or unintended effect of selective breeding. The likelihood of impaired locomotion suggests birth and rearing within the site vicinity. The animals were juvenile, apparently killed around the age of sexual maturity, when they would have attained maximum body mass. Purposeful funerary proceedings with deformed animals suggest (at least) a locally developed camelid husbandry.

RESUMO

Artifacts made from rays (rostral teeth and spine) are very common in shell mounds on the coast of São Paulo, Brazil. The presence of the genus Pristis among the studied species of elasmobranch fishes in this shell mounds reinforces the hypothesis these animals occurred in southeastern Brazil, and were used by hunter-gatherers. I analyzed twelve rostral teeth of the genus Pristis from shell mounds. The teeth have artificial marks left from making arrows and harpoons. The basic function of the teeth found in these shell mounds was the production of tools and ornaments. From the analyzed teeth, ten (83%) were associated to the faunal remain and two (17%) were associated with burials, and they can be considered as ceremonial or votive elements. There had been no new records of occurrence of the genus Pristis on the coast of São Paulo State in Brazil, and there are a few studies on the use of their products in many ancient and contemporary human communities. This paper provide data about the distribution of rays of this genus in archaeological sites and the use of this resource by hunter-gatherers on the coast of São Paulo.

A utilização de pontas (dentes rostrais e ferrões) provenientes das raias é muito comum em sambaquis do litoral de São Paulo. A presença do gênero Pristis entre as espécies de elasmobrânquios estudadas reforça a hipótese da ocorrência destes animais no sudeste brasileiro e sua utilização pelos grupos de caçadores-coletores. Eu analisei 12 dentes rostrais do gênero Pristis. Os dentes possuem marcas artificiais provenientes do trabalho realizado para a confecção de flechas e arpões. As funções básicas destes dentes seriam somente a de produção de ferramentas. Dos dentes analisados, 10 (83%) estavam associados aos vestígios faunísticos e, dois (17%) estavam associados à sepultamentos, podendo ser considerados como elemento cerimonial ou votivo. Estes são novos registros de ocorrência do gênero Pristis para o Estado de São Paulo, além de demonstrar a utilização destes por comunidades passadas e contemporâneas. Este trabalho contribui com dados sobre a distribuição das raias deste gênero em sítios arqueológicos e o seu uso como fonte de recursos para os grupos de caçadores-coletores do litoral de São Paulo.
