The manos and metates of Santa Rita Corozal, Belize are analyzed to compare traditional maize-grinding types to the overall assemblage. A reciprocal, back-and-forth grinding motion is the most efficient way to process large amounts of maize. However, rotary movements are also associated with some ground stone implements. The number of flat and trough metates and two handed manos are compared to the rotary-motion basin and concave type metates and one-handed manos to determine predominance and distribution. Flat is the predominant type and, together with the trough type, these grinding stones make up the majority of metates at the site. Manos are highly fragmented, but the two-handed variety is more common among those fragments able to be identified. While this would at first glance support a fully maize dependent subsistence, the presence of two additional non-reciprocal motion metate types and the fact that the trough metates are clustered in one sector of the site suggest that, in addition to maize, significant processing of other foods also occurred in association with these grinding stones.

The focus of this thesis is an analysis of a sample of dentition collected from the Postclassic Maya site of Santa Rita Corozal in Northern Belize. The goal of this study is to determine what the presence (or absence) of Linear Enamel Hypoplasia (LEH) can demonstrate about the general health (i.e. stress, disease, nutrition, and weaning age) and social status of a single subset of the Late Postclassic (900-1500 CE) Maya living at Santa Rita Corozal. Specifically, this thesis focuses on dentition of thirteen individuals from a large Postclassic platform group. The sample consists of sub-adult and adult female dentition from individuals that are associated with the same relative time period (Late Postclassic). The question being addressed in this thesis is: why has LEH presented in these individuals? These samples will also be compared to other studies involving LEH throughout the Maya area, in both similar and dissimilar environments. The preponderance of female and sub-adult remains also makes this platform group a very interesting topic of study for LEH in the Maya area, as it is unusual to find a concentrated area of individuals such as these. iv Importantly, the results of this study show that there is no significant relationship between general levels of stress and the overall status of an individual. Measurements collected from the LEH affected teeth demonstrate that all of the LEH episodes occurred before the age of 6. The mean age for the teeth sampled that show signs of LEH is 3.5 years, which is consistent with theories pertaining to the weaning age of the Maya during concomitant time periods. However, the size of this sample precludes any concrete conclusions about weaning ages and stress in general among the Maya at Santa Rita Corozal. It is also possible that these events are related to larger issues such as regional droughts or water-born disease.

Obsidian is one of the most common materials preserved in the archaeological record of Mesoamerica. Because of this and obsidian's unique chemical properties, it has become one of the most common means by which to explain ancient exchange and production. Northern Belize has largely been absent from discussions of Postclassic Mesoamerican economies. The limited amount of obsidian research that has been done is unable to draw comparisons to the region's primary site during this period, Santa Rita Corozal. This thesis remedies this by exploring the importation, production, and distribution of obsidian at the Postclassic Maya primary center of Santa Rita Corozal, Belize. Through the application of the lithic technology approach and the use of pXRF (portable X-ray fluorescence) spectrometry, it is possible to establish the sources of obsidian being exploited, the stage of reduction of obsidian imports, the major obsidian industry, and obsidian distribution for Santa Rita Corozal's Postclassic Period.

Chert tool production and exchange has long been studied for the Maya Preclassic to Terminal Classic Periods of Northern Belize (1000 B.C.-A.D. 950). It is increasingly clear that lithic systems of production and exchange were an integral part of the economic environment for this region, yet lithic research pertaining to the Maya Postclassic Period (A.D. 950-1530) is not well represented in the general literature. A recent examination of 110 chert, chalcedony, and obsidian small side-notched projectile points and point preforms, as well as 2,163 pieces of associated production debitage from two Late Postclassic households at Santa Rita Corozal, Belize, has yielded the identification of two lithic craft production areas. Examination of the complete lithic collection from these residences, as well as an additional 176 projectile points located throughout the site, reveals the need for new models of lithic production and exchange for this region during the Postclassic Period.
