NON-AVIAN DINOSAUR EGGSHELL CALCITE CONTAINS ANCIENT, ENDOGENOUS AMINO ACIDS

E. T. Saitta, J. Vinther, M. K. Crisp, G. D. Abbott, T. G. Kaye, M. Pittman, I. Bull, I. Fletcher, X. Chen, M. J. Collins, J. Sakalauskaite, M. Mackie, F. Dal Bello, M. R. Dickinson, M. A. Stevenson, , K. E. H. Penkman

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.

Enamel proteins reveal biological sex and genetic variability within southern African Paranthropus

P. P. Madupe, C. Koenig, I. Patramanis, P. L. Rüther, N. Hlazo, M. Mackie, M. Tawane, J. Krueger, A. J. Taurozzi, G. B. Troche, J. Kibii, R. Pickering, M. R. Dickinson, Y. Sahle, D. Kgotleng, , E. Cappellini

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.

Survival of mineral-bound peptides into the Miocene

B. Demarchi, M. Mackie, Z. Li, T. Deng, M. J. Collins, J. Clarke

This study shows that peptide sequences from ostrich eggshells survived for 6.5-9 million years, extending the known preservation of ancient proteins to the Miocene.
