Taphonomie des ensembles lithiques du Paléolithique moyen en contexte loessique

Les Nouvelles de l’Archéologie, 2009
The periglacial climatic environment affected most of the European Palaeolithic settlements. The dynamic processes, especially produced by frost, have altered distinctive morphology and spatial distribution of lithic artefacts. The possible similarity of

Lions as Bone Accumulators? Exploring Multi‐Predator Contributions to the Olduvai Carnivore Site (OCS) (Tanzania) Through AI and Metric Analyses

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Lions (Panthera leo) are apex predators with a well‐documented influence on ecological dynamics, yet their potential role as bone‐accumulating agents remains poorly understood and often debated. Previous taphonomic studies have largely attributed bone accumulations in African savannah ecosystems to other carnivores, such as spotted hyenas ...

Rebuilding Earth’s first skeletal animals: the original morphology of Corumbella (Ediacaran, Brazil)

Royal Society Open Science
The evolutionary onset of animal biomineralization in the late Ediacaran (ca 555–538 Ma) is marked by the global appearance of enigmatic tubular fossils with unresolved phylogenetic relationships.

Trace fossils associated with Burgess Shale non-biomineralized carapaces: bringing taphonomic and ecological controls into focus [PDF]

Royal Society Open Science, 2019
The association of trace fossils and non-biomineralized carapaces has been reported from Cambrian Lagerstätten worldwide, but the abundance, ichnodiversity, taphonomy and ecological significance of such associations have yet to be fully investigated. Two

Evidence of microbial activity from a shallow water whale fall (Voghera, northern Italy) [PDF]

, 2012
The fossil bones, associated carbonate cements and enclosing concretion of a Miocene mysticete from inner shelf deposits (Monte Vallassa Formation, northern Italy) were analyzed for evidence of microbial activity. Optical and scanning electron microscopy,

Sharp Force Trauma and Chop Mark Identification Bias: Experimental Evidence on the Effects of Bone Morphology, Cortical Thickness, and Ax Material

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Sharp force trauma (SFT) is the main criterion used to identify chop mark butchery in zooarchaeology, yet its reliability as a diagnostic feature has not been systematically tested. Chop marks reflect both cutting and fracturing processes and exhibit characteristics of both sharp and blunt trauma.

Porcupine gnaw marks on a Late Pliocene bone from the Upper Siwaliks exposed near Village Khetpurali (Haryana, India)

Anais da Academia Brasileira de Ciências, 2019
Abstract:Bone accumulation by porcupines at archaeological sites is well known. However, in paleontological sites such a taphonomical occurrence is rather rare. We here report porcupine (Hystrix sp.) gnaw marks on an unidentified bone fragment, dated to ~

Using microstructures and composition to decipher the alterations of rodent teeth in modern regurgitation pellets—a good news-bad news story

, 2020
Rodent accumulations are widely used for palaeoenvironmental reconstructions. But these accumulations are created through the activity of predators (carnivorous mammals, birds of prey), the predation and digestion of which modify the preservation of ...

Hidden Insights: Comprehensive Radiological Analysis of Four Skeletal Populations From 13th–19th Century Southern Finland Reveals Neoplastic and Other Lesions Invisible on Bone Surfaces

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This study aims to identify lesions confined to the internal structures of bones. A radiographic analysis was performed on 219 archaeological, historical period skeletons from southern Finland. Although the study examines nearly all preserved skeletal elements using plain radiographs, it does not incorporate computed tomography.
