The paper analyzes amino acids in non-avian dinosaur eggshells, finding evidence of endogenous proteins preserved through closed-system processes, but also indicating complete hydrolysis of most amino acids.

This study uses enamel proteomics to determine biological sex and assess intraspecific variation in Paranthropus robustus from South Africa, supporting the idea that morphological variation may reflect taxonomic diversity.

This paper introduces a new method for enamel amino acid racemization dating using a closed system approach, showing its potential for relative dating of mammalian remains beyond current methods.
