Species identification of skeletal remains is a central duty in forensic anthropology. This process can be made difficult or impossible due to taphonomic changes, including burning, that lead to fragmented or distorted remains. This study employs histomorphological and histomorphometric methods, such as measuring osteon area and circularity, to determine if species differentiation is possible in skeletal remains burned at 600°C and 700°C. The right femora, ulnae, and sixth ribs were obtained from a cow, white-tailed deer, dog, human, pig, and raccoon (all species n=1) for analysis. Control groups were compared with eperimental groups burned in a controlled environment to discern skeletal histological changes due to burning. Qualitative assessments and descriptive statistics were collected and analyzed. At 600°C, histomorphological variables (eg. cement lines, osteocyte lacunae, etc.) remained visible and histmorphometry could be measured. At 700°C, only degraded endosteal cement lines and Haversian canals were present, preventing the accurate usage of histomorphometry. This study reaffirms the utility of these methods in remains burned at temperatures of up to 600°C by detecting differences in histomorphology and osteon geometry between human and nonhuman samples.
