Understanding people through the foods eaten has proven a formidable method to uncover subsistence patterns and infer lifestyle of the earliest inhabitants of an area. With previously examined paleodiet from East Okeechobee Area, Tatham Mound, and Fort Center, particular areas of Florida’s prehistory have begun to resurrect thorough the eye of the scientist. When we understand the foods consumed, we also corroborate that with the environment where the individual resided. Reconstructing foods...
Show moreUnderstanding people through the foods eaten has proven a formidable method to uncover subsistence patterns and infer lifestyle of the earliest inhabitants of an area. With previously examined paleodiet from East Okeechobee Area, Tatham Mound, and Fort Center, particular areas of Florida’s prehistory have begun to resurrect thorough the eye of the scientist. When we understand the foods consumed, we also corroborate that with the environment where the individual resided. Reconstructing foods eaten not only helps researchers understand the ecology of the habitat, but also the social structure of the group the person belonged to. The conglomeration of these factors enables investigators to understand the people, culture, and environment of a region when photographs and written records are unavailable and unaccountable. Using the stable isotopes of carbon, nitrogen, and oxygen, a molecular analysis of the collagen and apatite of bones and tooth enamel signifies the quantities and qualities of proteins and carbohydrates eaten by an individual. This method will be utilized and highlighted in the paleodietary analysis of two sites from the inland zone of southeastern Florida. Two South Florida archaeological sites were discovered housing human remains in the early 1970s. Markham Park and Lauderhill Mound are the two sites used for this analysis. Because of the pottery sherds associated in chronological stratigraphic layers, the date range for each site has been shown to differ by about 500 years. This is significant to assess if the diet compares or contrasts throughout the different time periods.

When unidentified skeletal remains are found, researchers utilize a number of methods to apportion details for a biological profile. While these practices are used and professed through generations of students, they also require a reevaluation of the methods. This project estimates the ancestry and sex of nine unknown skeletal individuals through two different mechanisms.

Show moreWhen unidentified skeletal remains are found, researchers utilize a number of methods to apportion details for a biological profile. While these practices are used and professed through generations of students, they also require a reevaluation of the methods. This project estimates the ancestry and sex of nine unknown skeletal individuals through two different mechanisms. Modified biological profiles were completed through two different methodologies: anthroscopic traits (Buikstra and Ubelaker 1994; White et al. 2012) and geometric morphometrics using 3D-ID (Slice and Ross 2009). The results serve two purposes: (1) to provide ancestry and sex (2) to compare two methodologies through outcomes and repeatability of results. Intra-observer error testing was conducted on both methods. All outputs resulted in low intra-rater reliability, highlighting the repeatability error in one observer’s collection methods. These results conclude and encourage the reevaluation and standardization of the procedures and comparison groups used to assess ancestry and sex.
