Amino Acids and Proteins in Fossil Biominerals

AMINO ACIDS AND PROTEINS IN FOSSIL BIOMINERALS

An essential cross-disciplinary guide to the proteins that form biominerals and that are preserved in the fossil record

Amino Acids and Proteins in Fossil Biominerals is an authoritative guide to the patterns of survival and degradation of ancient biomolecules in the fossil record. The author brings together new research in biomineralization and ancient proteins to describe mechanisms of protein diagenesis.

The book draws on the author's experiences as well as current information from three research fields: geochemistry, archaeology and Quaternary sciences. The author examines the history of the study of ancient proteins, from the dating of Quaternary biominerals to the present advances in shotgun proteomics, and discusses their applications across archaeology, geology and evolutionary biology.

This important guide:

• Explores the main components of biominerals

• Describes the breakdown of proteins in fossils

• Reviews the applications of ancient protein studies

Written for students and researchers of biomolecular archaeology and palaeontology, Amino Acids and Proteins in Fossil Biominerals provides a cross-disciplinary guide to the proteins responsible for the formation of biominerals and to the survival of biomolecules in the archaeological and palaeontological record.

This book forms one volume of the popular New Analytical Methods in Earth and Environmental Science Series.
