The Taphonomic Factors On Human Remains Inside Chullpas: Marcajirca, Peru, Samantha Lauren Lininger

Masters Theses

This study explored the taphonomic factors that contributed to the preservation of human skeletal remains inside ancient above-ground tomb in Marcajirca, Peru. This study incorporated one hundred and eighteen bones from three chullpas. Five taphonomic factors were examined: bone type, plant activity, root presence, weathering, and cultural factors. Surface layers inside each chullpa were analyzed using Geographic Information System (GIS) software. Chi-square tests were employed to investigate preservation and taphonomic factors. The results from the statistical tests indicated that there was a significant difference in the taphonomic factors on different bone types. Chullpa 6 was significant because it was unique …

Raccoon Scavenging And The Taphonomic Effects On Early Human Decomposition And Pmi Estimation, Jacob K. Smith

Masters Theses

Forensic investigators must consider the effects of numerous taphonomic variables when estimating the postmortem interval (PMI) in forensic cases, such as temperature and insect activity. Efforts to quantify the decomposition process have been made. Megyesi et al. (2005) modified the categories and stages of decomposition presented by Galloway et al. (1989), and introduced a total body scoring system that uses accumulated degree-days to estimate PMI. However, none of these systems include the potential effects of animal scavenging. Galloway et al. (1989) stated that carnivorous activity occurs mainly during advanced decomposition and mummification. Haglund et al. (1989) specifically investigated canid scavenging …

Studies In Taphonomy: Bone And Soft Tissue Modifications By Postmortem Scavengers, Jennifer Ann Synstelien

Doctoral Dissertations

This study documented animal scavengers at the University of Tennessee’s Anthropology Research Facility. Remotely-captured digital video and still photography equipment was stationed at the outdoor human decomposition facility intermittently from September 2003 through October 2009. The primary scavengers of corpses were identified as the northern raccoon (Procyon lotor), Virginia opossum (Didelphis virginiana), brown rat (Rattus norvegicus), and white-footed mouse (Peromyscus leucopus); and the primary scavenger of skeletal remains was the eastern gray squirrel (Sciurus carolinensis). Among these species, the raccoon was the dominant scavenger and is the focus of this report.

The Preservation And Persistence Of Human Dna In Soil During Cadaver Decomposition, Alexandra Leah Emmons

Masters Theses

Recent decades have seen a marked increase in the amount of research concerning the impact of human cadaveric decomposition on the grave soil environment; however, despite such advances, the fate of important biological correlates in grave soil, including human DNA, have remained relatively understudied. This study redresses the current lack of knowledge regarding the preservation and persistence of human DNA in the soil during cadaveric decomposition, with the purpose of enhancing forensic identification efforts including the detection of primary burial sites. This study assessed the preservation (i.e., presence or absence) of human nuclear and mitochondrial DNA and evaluated the quantity …

A Descriptive Study Of Forensic Implications Of Raccoon Scavenging In Maine, Ashley Hannigan

Honors College

This thesis is a case study of winter raccoon scavenging in Maine. The data used for my analysis came from a National Institute of Justice funded project on Regional Taphonomy done by Marcella Sorg from 2007 to 2012 (Sorg, 2013). I analyzed the photographic and videographic data from one pig cadaver site and identified raccoon scavenging “events.” This term is used to describe any period of time that one or more raccoons are scavenging. These events were then analyzed to investigate possible associations between scavenging behaviors and environmental variables, although none were positively identified. I adapted a method of describing …

Parasitology In An Archaeological Context: Analysis Of Medieval Burials In Nivelles, Belgium, S. E. Rácz, Elisa Pucu De Araujo, E. Jensen, C. Mostek, Johnica J. Morrow, M. L. Van Hove, R. Bianucci, D. Willems, F. Heller, Adauto Araujo, Karl Reinhard

Coprolites were recovered from three burials near the Grand Place of Nivelles, Belgium. These remains yielded evidence of geohelminth parasitism. The evidence contributes to studies of differential parasite egg preservation related to the taphonomic conditions within the three burials. Using coprolite analysis techniques, parasite egg concentrations were quantified for each burial. Coprolites from the individual in Burial 122 were abnormally large and abundant, indicating an intestinal blockage. Additionally, this individual hosted an extremely high number of parasites evinced by the calculated parasite egg concentrations (Trichuris trichiura = 1,577,679 total eggs; Ascaris lumbricoides = 202,350 total eggs). Statistical analyses revealed …

Curatorial Implications Of Ophyra Capensis (Order Diptera, Family Muscidae) Puparia Recovered From The Body Of The Blessed Antonio Patrizi, Monticiano, Italy (Middle Ages), Johnica J. Morrow, Diesel A. Baldwin, Leon G. Higley, Dario Piombino-Mascali, Karl J. Reinhard

Karl Reinhard Publications

The discovery of dipteran remains on mummified individuals can lead to either cause for curatorial concern or to a better understanding of the individual’s post-mortem environment. The present study analyzed insect remains associated with the body of a unique medieval mummy of religious significance, that of the Blessed Antonio Patrizi da Monticiano. A total of 79 puparia were examined and all were identified as Ophyra capensis (Diptera: Muscidae). Additionally, a desiccated moth (Lepidoptera: Tineidae) was encountered. Puparia of O. capensis would be associated with normal decomposition shortly after the death of the mummified individual, and not an infestation beginning during …

An Evaluation Of Geophysical Methods In The Detection Of Toddler-Sized Burials During The First Six Months Of Burials, Paul Sullivan Martin

Electronic Theses and Dissertations

Geophysical survey has become a major tool in the search for clandestine graves associated with missing person cases. However, relatively little research has been done to evaluate the efficacy of different instruments. Ground-penetrating Radar (GPR), magnetometry, resistivity, conductivity, and susceptibility survey data were collected over the first six months of interment at approximately 30-day intervals for two research plots: an open grassy area and a wooded area. Each area contained five pig burials representing toddler-size (less than 50 pounds) remains and two areas of disturbance or false burials to serve as control graves. The resultant imagery was evaluated in terms …
