Abstract Accurate identification of bone surface modifications (BSM) is crucial for the taphonomic understanding archaeological and paleontological sites. Critical interpretations when humans started eating meat animal fat or they using stone tools, occupied new continents interacted with predatory guilds impinge on accurate identifications BSM. Until now, Plio-Pleistocene BSM have been contentious because high uncertainty in discriminating among agents. Recently, use machine learning...
Abstract Bone surface modifications are foundational to the correct identification of hominin butchery traces in archaeological record. Until present, no analytical technique existed that could provide objectivity, high accuracy, and an estimate probability multiple structurally-similar dissimilar marks. Here, we present a major methodological breakthrough incorporates these three elements using Artificial Intelligence (AI) through computer vision techniques, based on convolutional neural...
Abstract Humans are unique in their diet, physiology and socio-reproductive behavior compared to other primates. They also the ubiquitous adaptation all biomes habitats. From an evolutionary perspective, these trends seem have started about two million years ago, coinciding with emergence of encephalization, reduction dental apparatus, adoption a fully terrestrial lifestyle, resulting modern anatomical bauplan, focalization certain activities landscape, use stone tools, exit from Africa. It...
Taphonomic works aim at discovering how paleontological and archaeofaunal assemblages were formed. They also determining hominin fossils preserved or destroyed. Hominins other mammal carnivores have been co-evolving, least during the past two million years, their potential interactions determined evolution of human behavior. In order to understand all this, taxon-specific carnivore agency must be effectively identified in fossil record. Until now, taphonomists able determine, some degree,...
Human carnivory is atypical among primates. Unlike chimpanzees and bonobos, who are known to hunt smaller monkeys eat them immediately, human foragers often cooperate kill large animals transport a safe location be shared. While it that meat became an important part of the hominin diet around 2.6–2 Mya, whether intense cooperation food sharing developed in conjunction with regular intake remains unresolved. A widespread assumption early hominins acquired animal protein through...
Misiam is a modern wildebeest-dominated accumulation situated in steep ravine covered with dense vegetation at Olduvai Gorge (Tanzania). It interpreted here as leopard lair to which carcasses have been transported for several years. Felid-specific bone damage patterns, felid-typical skeletal part profiles, taxonomic specialization and the physical presence of leopards observed by authors show that can be specialized medium-sized carcass accumulators. Hyenas also intervened intervals...
Abstract The ability to control and direct fire is a major evolutionary step in the human story. development of aceramic cooking technologies less well understood as they rarely survive archaeological record. However, inferential evidence such fire-cracked rocks, earthen pits heated bones suggest variety methods were used prior invention ceramics. Yet there paucity experimental testing efficacy perishable organic containers tasks involving their use with heat. study presents results for...
Abstract Artificial intelligence algorithms have recently been applied to taphonomic questions with great success, outperforming previous methods of bone surface modification (BSM) identification. Following these new developments, here we try different deep learning model architectures, optimizers and activation functions assess if it is possible identify a stone tool’s raw material simply by looking at the cut marks that created on bone. The models correctly discerned between flint,...
Deep learning models are based on a combination of neural network architectures, optimization parameters and activation functions. All them provide exponential combinations whose computational fitness is difficult to pinpoint. The intricate resemblance the microscopic features that found in bone surface modifications make their differentiation challenging, determining baseline optimizers functions for modeling seems necessary economy. Here, we experiment with most resolutive (relu, swish,...
Studying bone surface modifications (BSMs) in neotaphonomic research is an important aid to reconstruct agency the archaeological and palaeontological record. The significance of correctly identifying BSMs has led extensive debates about adequate methodological interpretive frameworks identify taphonomic agents their bone-modifying patterns dynamic processes; especially those involving inter-agency interactions. Recent analytical innovations field have given rise more updated less biasing...
Este artículo analiza el estado actual de los estudios arqueológicos en cementerios prehistóricos e históricos estudiados Campo Montiel a partir la bibliografía existente. La revisión tiene como objeto poner relieve cómo se viene estudiando registro funerario esta comarca ciudadrealeña así conocer grado implantación análisis antropológicos, especialidad indudable valor para poder profundizar vida real las sociedades del pasado.

We present the discovery of a Middle Pleistocene fossil assemblage at Los Villares (Ruidera, Ciudad Real, Castilla-La Mancha), which has possible evidence associated human activity. The potential site been evaluated through multidisciplinary research including taxonomy, anatomy, deep learning, and direct dating remains. A surface study carried out in 2017, over very limited area (2 m2) on slope one Ruidera lakes led to more than 50 specimens, cranial (mainly teeth) postcranial This rich is...
