The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

open access: yesIntegrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Hair Degradation Patterns in Aquatic and Soil Environments

open access: yesArchaeometry, EarlyView.
ABSTRACT Hair is a biological material that can provide information in archaeology and forensics. Previous studies have mainly examined changes occurring post‐mortem. In this study, we focused on hair pulled out ante‐mortem. The aim of the study was to identify patterns in the degradation of hair in water and soil.

Methodological Concerns and Interpretation of Archaeometric Data in Recent Provenance Claims Concerning the Riace Bronzes

open access: yesArchaeometry, EarlyView.
ABSTRACT Recent claims proposing a Syracusan provenance for the Riace Bronzes rely on selective petrographic, geochemical, and taphonomic evidence that raises crucial methodological questions. This paper critically reassesses the analytical premises and inferential logic underlying these claims, showing that they bypass established protocols in ceramic

The Early Upper Palaeolithic open‐air site of Friedrichsdorf‐Seulberg, Germany, in the context of the northern central European Aurignacian

open access: yesBoreas, EarlyView.
Our knowledge of the Early Upper Palaeolithic occupation in northern central Europe is very limited, and recent research at the open‐air site of Friedrichsdorf‐Seulberg in Hesse, Germany, provides important new information on the Aurignacian. The site is rather small (26.5 m2) and spatial analysis identified a central hearth with two associated ...

Early to Mid‐Holocene molluscan community dynamics in Billefjorden, central Svalbard: the interplay of local geomorphology and regional climate

open access: yesBoreas, EarlyView.
The postglacial evolution of High Arctic coastal environments is recorded in the rich fossiliferous archives of raised marine terraces. This study employs a multi‐proxy approach combining molluscan community analysis, taphonomy and sedimentology to reconstruct the Early to Mid‐Holocene environmental dynamics of the Mimerdalen embayment in the ...

On Taphonomy of art : An origin of art [PDF]

open access: yes
The discovery of Parietal art at Chauvet, France, in 1994, for long time, has shocked the academic world of specialists for prehistoric arts. Above all, the absolute date of pigments used for confronting rhinoceros, for example, about 32,000 BP, is ...
