This dissertation focuses on the development of radiocarbon dating residues from stone artefacts.
Methods used for this study comprised of microscopic residue and use wear analyses, including Scanning Electron Microscope Energy Dispersive X-ray (SEM-EDX) observations.
Experimental studies evaluated contaminant cleaning from stone tools and residue extraction methods.
We study the pottery and how it changes over the broad sweep, some 3,000 years.
There are people who are experts in all these different periods of pottery or Egyptian ceramics.
Chances are, right now, you have a Gregorian calendar stuck to your wall.
This calendar, with the months January through December, is a business standard used in many places round the world to define the year: one which hearkens back to Christian and Roman Imperial precedents.
Rarely do we have people from thousands of years ago who are writing, who are signing confessions.
So there's no one easy way that we know what the date of the pyramids happens to be. The pyramids are surrounded by cemeteries of other tombs. Sometimes we find organic materials, like fragments of reed, and wood, wooden coffins.
But other timekeeping methods exist and are still used in the modern world, circumventing the easy processing of dates and history between cultures.
Throughout history, time has been defined in a variety of ways: by everything from the current ruler, or empire, or not defined at all.
While radiocarbon dating of blood residues had been previously reported, dating accuracy required further substantiation.
