Paleontology dating methods
Radiographs revealed a skull with the cranium and mandible disarticulated within the plastic matrix (Figure 1).
The disarticulation suggested that the cranium and mandible were most likely skeletonized at the time of their immersion into the liquid plastic.
Standard 14C dating is based on the work of Nobel Laureate Willard Frank Libby (1908-1980) (Libby 1946), which was inspired by the research of a cosmic-ray physicist, Serge A. Although Libby initially kept his findings secret because he thought the idea was too ludicrous to gain financial support, 14C dating has ultimately revolutionized archeology, geology, geophysics, and other branches of science (Taylor 2000).
The radiocarbon dating method recognizes that living plants and animals maintain amounts of the carbon isotope 14C, which are close to atmospheric levels.
Numerous teeth were missing both ante- and postmortem.
The recovered objects were taken to the local medical examiner to have the skull removed from the plastic matrix and to be analyzed.In particular, application of the Lamendin technique (Lamendin et al.1992; Prince and Ubelaker 2002) for age estimation from characteristics of single rooted teeth to the right maxillary canine indicated an age at death greater than 50 years.To clarify time since death, radiocarbon analysis was conducted.The results were compared using the modern bomb curve.
