Bioarchaeology is one of the most exciting areas of archaeological science and biomolecules (e.g. DNA, proteins, lipids) are at the forefront of this research. This module provides hands-on practical experience in the collection, analysis and interpretation of biomolecular data (stable isotopes, proteins) to understand diet in past societies using collagen extracted from archaeological bones. Students have said how much they enjoy this module for its varied classes, especially the lab work with real archaeological material, and the enthusiasm of the module leader.

The Practical Skills modules seek to introduce you to a range of skills in various diverse areas of archaeological practice and are designed to allow you to gain experience in a 'hands-on' manner.
This specific module aims to:
To introduce the intellectual context and working methods of the study of biomolecules from archaeological deposits such as bones and pottery residues.
To provide an introduction to good laboratory practice
To provide laboratory experience in collagen extraction for stable isotope analysis and ZooMS
To introduce how we analyse and interpret results from stable isotope analysis and ZooMS
To encourage a questioning approach to the collection and analysis of a specific class of archaeological data
By the end of the module, students should be able to:
This is an optional module, part of the suite of Spring Term practical modules. It has a companion Team Project which will run in the Summer Term.
In this module, students learn how to extract and analyse collagen from archaeological bones safely in the laboratory using GLP (Good Laboratory Practice). Two different biomolecular techniques are applied - ZooMS to determine the species of the bone and carbon and nitrogen stable isotope analysis to investigate diet. This module will be taught through lectures (including an introductory lecture on pottery residue analysis) and practical sessions in a wet chemistry lab (collagen extraction) and a computer lab (data analysis and interpretation).
Through the term, students will be also expected to develop their skills in critiquing recent papers in biomolecular archaeology, and begin to explore data (students will conduct their own data analysis in the co-requisite module the following term so it is important that they understand good practice). Students keep a lab notebook during term and a computer practical test will assess their laboratory skills in addition to their understanding of collagen extraction, stable isotopes and zooms.

Formative: The marker will share written feedback with you in a timetabled one-to-one meeting and you will have the opportunity to ask further questions about how to improve your work before your summative assessment. If you are unable to attend the feedback session, your tutor will share the formative feedback with you digitally.
Summative: Written feedback sheets will be uploaded to your e:vision account (your personal University of York online services account) within 20 working days of the submission deadline, along with your overall mark for the module. If you have any questions about your mark and/or your written feedback, you will be able to sign up for office hours with the marker.
