Bone collagen from subtropical Australia is preserved for more than 50,000 years

Communications Earth & Environment, 2023
Ancient protein studies have demonstrated their utility for looking at a wide range of evolutionary and historical questions. The majority of palaeoproteomics studies to date have been restricted to high latitudes with relatively temperate environments ...

Reconstructing Asian faunal introductions to eastern Africa from multi-proxy biomolecular and archaeological datasets.

PLoS ONE, 2017
Human-mediated biological exchange has had global social and ecological impacts. In sub-Saharan Africa, several domestic and commensal animals were introduced from Asia in the pre-modern period; however, the timing and nature of these introductions ...

Discrepancies between High-Resolution Native and Glycopeptide-Centric Mass Spectrometric Approaches: A Case Study into the Glycosylation of Erythropoietin Variants [PDF]

, 2021
Glycosylation represents a critical quality attribute modulating a myriad of physiochemical properties and effector functions of biotherapeutics. Furthermore, a rising landscape of glycosylated biotherapeutics including biosimilars, biobetters, and ...

Integrating ZooMS and Zooarchaeology to Assess the Châtelperronian and Carnivore Occupations at Cassenade (Dordogne, France)

PaleoAnthropology
Archaeological animal bone assemblages are often highly fragmented, meaning that for over 70% of the recovered bone fragments we do not know what animal (or human) species they belonged to.

Towards a Deeper Integration of ZooMS and Zooarchaeology at Palaeolithic Sites: Current Challenges and Future Directions

PaleoAnthropology
Advances in biomolecular methods, in particular the study of ancient proteins (palaeoproteomics), have revolutionised how we can taxonomically identify archaeological bone fragments. Alongside traditional zooarchaeological assignments based on the visual

The Early Upper Palaeolithic in British caves: problems and potential Le Paléolithique supérieur ancien dans les grottes de Grande‐Bretagne : problèmes et potentiels

Journal of the Royal Anthropological Institute, EarlyView.
Recent years have seen landmark progress in our understanding of early Homo sapiens occupation of Europe, owing to new excavations and the application of new analytical methods. Research on British sites, however, continues to lag. This is because of limitations inherent in existing cave collections, and limited options for new fieldwork at known sites.

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

Boreas, 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 ...
