Composition variations in archaeological human bone proteomes

The paper compares proteome composition and modification in different bone types from archaeological human skeletons, finding cortical bone better preserves proteins than trabecular bone and petrous bone has the most complex proteomes.

Archaeological preservation of amelogenesis pathways

The paper analyzes archaeological dental enamel proteomes to study the effects of amelogenesis on protein digestion and phosphorylation, and introduces a new marker for estimating genetic sex.

Identification and removal of contamination in palaeoproteomic analysis of dental enamel

The paper investigates contamination in palaeoproteomic analysis of dental enamel and finds that simple water or bleach washes before demineralization effectively remove contamination without harming endogenous proteins.

New methods on the block: Taxonomic identification of archaeological bones in resin-embedded sediments through palaeoproteomics

This paper demonstrates the successful retrieval of palaeoproteomic data from bone fragments in resin-impregnated sediment blocks, enabling microstratigraphic taxonomic identification of Pleistocene faunal remains.

Cleaning the Dead: Optimized decontamination enhances palaeoproteomic analyses of Pleistocene skeletal material

This study evaluates decontamination methods for ancient proteins, finding that a brief bleach wash effectively removes modern contamination without damaging endogenous proteins from Pleistocene specimens.

Ancient biomolecular analysis of 39 mammoth individuals from Kostenki 11-Ia elucidates Upper Palaeolithic human resource use

The paper analyzes biomolecular data from 39 mammoth individuals to understand Upper Palaeolithic human resource use, finding no sex-based foraging differences in Late Pleistocene megafauna.
