Acknowledgements

I would like to thank Dr. John Southon, the director of the UCI Keck-CCAMS Lab, for giving me the opportunity to get the headrest dated, which has allowed for the majority of my research to go through.

Thank you to Dr. Lynn Swartz Dodd for the photos as well as continued help in my quest in finding helpful information for the headrest.

Many thanks to Milan Medakovic and the Academic Research Funding Board at the University of Southern California for their help in paying for the dating done at the UCI facilities.
