A 20+ Ma old enamel proteome from Canada's High Arctic reveals diversification of Rhinocerotidae in the middle Eocene-Oligocene

This paper retrieves ancient enamel protein sequences from a 21-24 Ma rhinocerotid, providing new phylogenetic insights into Rhinocerotidae diversification during the middle Eocene-Oligocene.

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

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

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

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.

Early Pleistocene enamel proteome sequences from Dmanisi resolve Stephanorhinus phylogeny.

This study uses Early Pleistocene dental enamel proteome sequences to resolve the phylogeny of Stephanorhinus, showing it is paraphyletic and requiring systematic revision.
