For over a century this was one of the few dating methods available to archaeologists, but unfortunately it could not offer specific dates.

Another early dating method was ‘typology’, defined as the classification of artefacts according to their physical characteristics.

Thus the converging micro-topographical examinations and hydrogen profiles of the samples surfaces indicate that the skull is probably not a pre-Columbian artefact but has been carved in the 18th or 19th century.

Although development of radiometric methods led to the first breakthroughs in establishing an absolute time scale, other absolute methods have limited applications.In addition, the ERDA method carried out with an external beam presented here provides a new and simple approach for the nondestructive authentication of quartz-based archaeological artefacts by QHD.
