AI Article Synopsis

  • The Taguatagua 3 site in Central Chile, from the late Pleistocene, reveals important insights into early hunter-gatherer mobility and settlement patterns in southern South America.
  • Dating indicates human occupation occurred about 12,440-12,550 cal yr BP, primarily related to gomphothere hunting, along with other activities like hide preparation and food processing.
  • The site served as a crucial temporary camp during the dry season, highlighting the Tagua Tagua lake as a key resource hub for hunter-gatherers in the region.

Article Abstract

We present the results of the excavations and analyses of the diverse and exceptional archaeological assemblage of Taguatagua 3, a new late Pleistocene site located in the ancient Tagua Tagua lake in Central Chile (34°S). The anthropogenic context is constrained in a coherently dated stratigraphic deposit which adds new information about the mobility, subsistence strategies, and settlement of the early hunter-gatherers of southern South America. The age model constructed, as well as radiocarbon dates obtained directly from a combustion structure, indicate that the human occupation occurred over a brief time span around 12,440-12,550 cal yr BP. Considering taphonomic, geoarchaeological, lithic, archaeobotanical, and zooarchaeological evidence, as well as the spatial distribution combined with ethnographic data, we interpret Taguatagua 3 as a logistic and temporary camp associated mainly with gomphothere hunting and butchering. Nevertheless, several other activities were carried out here as well, such as hide and/or bone preparation, small vertebrate and plant processing and consumption, and red ochre grinding. Botanical and eggshell remains suggest that the anthropic occupation occurred during the dry season. Considering the contemporaneous sites recorded in the basin, we conclude that the ancient Tagua Tagua lake was a key location along the region's early hunter-gatherer mobility circuits. In this context, it acted as a recurrent hunting/scavenging place during the Late Pleistocene due to its abundant, diverse, and predictable resources.

Introduction: is a freshwater turtle species endemic to northeastern Thailand and Lao PDR. While is relatively common and widespread in Thailand, its population size and demographic trends remain largely unknown, as direct population estimates are lacking. This species faces significant threats from consumption, exploitation, and trade.

Late Pleistocene onset of mutualistic human/canid ( spp.) relationships in subarctic Alaska.

Large canids (wolves, dogs, and coyote) and people form a close relationship in northern (subarctic and arctic) socioecological systems. Here, we document the antiquity of this bond and the multiple ways it manifested in interior Alaska, a region key to understanding the peopling of the Americas and early northern lifeways. We compile original and existing genomic, isotopic, and osteological canid data from archaeological, paleontological, and modern sites.

The genus is endemic to South Africa but has never undergone a phylogeographic review. This study aims to unravel the phylogeographic patterns and history of the many species which occur in the greater Karoo region. A fossil-calibrated phylogeny was produced based on three gene regions (CO1, 16S and EF-1ɣ) for (Cor-k-lid trapdoor spiders) specimens collected in the Karoo region, to infer dates of origin and diversification.

Article Synopsis
  • - The study examines potential bone disease in an extinct primate from late Pleistocene Brazil using skull and post cranial remains from a museum collection.
  • - Radiographic and CT imaging revealed pathological changes like cortical thickening and sclerosis, suggesting the presence of metabolic bone disease similar to Paget's disease.
  • - The findings represent a unique case of metabolic bone disease in a New World monkey, although limitations due to lack of comparative skeletal materials necessitate careful interpretation of the results.
