Periosteal changes on the upper limb bones as the indicator of taphonomic processes (Pohansko, 2nd church)
Salavová, Šárka ; Sládek, Vladimír (advisor) ; Pankowská, Anna (referee)
The preservation of the bones and their appearance depends on the conditions in which the individual was buried. The aim of the diploma thesis was to explore protocols, quantify periosteal changes and try to interpret them. For quantification, we chose the upper limb - the cingulum membri superioris and pars libera membri superioris without the skeleton of the hand (ossa manus). We examined skeletal remains of 55 individuals (25 women, 30 men) from the burial site at the 2nd church in Pohansko. The burial site dates back to the Great Moravia period (the end of the 9th and beginning of the 10th century). We recorded periosteal changes in images that we digitized in InkScape. In InkScape, we localized periosteal changes, and using ImageCalculator, we found the area of percentage of periosteal changes on the bone surface. We observed two types of periosteal changes: bone damage (for example absence of periosteal surface, exposed spongiosis) and color changes (for example orange, black or green discoloration). By digitizing protocols and processing them in InkScape, we analyzed the areas of occurrence for individual periosteal changes and, using ImageCalculator, we found the most common area of periosteal changes. The most frequent bone damage was the absence of the periosteal surface and the most...
