Past Research Projects

Plants and Mortuary Offerings at Palenque, Chiapas, Mexico

Éloi Bérubé examined the residues of plants in ceramic vessels recovered from burials at the site of Palenque, Chiapas, Mexico. Bérubé identified phytoliths and starch grains extracted from those vessels to provide an understanding of plants possibly placed along with the vessels as offerings. These data have allowed for a better understanding of mortuary practices at the site of Palenque.

Ethnoecology, Resilience, and Cuisine at the Crossroads: Proyecto Arqueológico Río Amarillo-Copán (PARAC), Copan, Honduras

Shanti Morell-Hart studied changes in human-environmental transformations over time, comparing cuisines from several ancient communities within and near the Copán area of Northwestern Honduras.  She recovered a rich archaeobotanical data set that included both microbotanical and macrobotanical residues recovered from bulk flotation samples and extracted from artifacts.  She addressed evidence of human resilience during times of social and climatological stress.  She also explored the dynamic overlap between northern and southern societies, where Northwestern Honduras served as a sort of regional crossroads.

Diet, Food Security, and Sociopolitical Change in the Classic Maya Usumacinta Basin

Meghan Macleod studied dietary trends as they relate to the sociopolitical environment and food security of Classic period (350-950 CE) Maya populations in the Usumacinta Basin. In the field in Chiapas, she extracted microbotanical samples from human teeth and floated macrobotanical samples in search of evidence of plant food consumption. 

Agricultural Practices and Human-Environmental Relations at Motul de San José

Sophie Reilly investigated questions surrounding agricultural practices and human-environmental relations at the Maya site Motul de San José. Reilly employed phytolith analysis of soil samples excavated from various sectors throughout the site.  She traced the sectors that may have been used for agriculture and which plant species people may have been cultivating. This research has contributed to knowledge about how people at Motul de San José interacted with their environment, furthering research about daily life in the Classic Maya Period.

Mixtec Foodways During the Early Colonial Period: Analysis of food residues and interpretation of practices

For his MA thesis, Éloi Bérubé studied shifts in foodways between the Postclassic period (900–1521 AD) and the Early Colonial period (1521–1600) at the site of San Miguel de Achiutla, Oaxaca.  He assessed to what extent the Mixtecs resisted, accepted or negotiated Spanish cultural elements in their own daily and ritual lifeways. At the MPERF, he extracted macrobotanical residues from bulk flotation samples, and phytolith and starch grain residues from artifacts. He compared the foods consumed during the Early Colonial period at Achiutla to those that were consumed before Spanish Contact.

Foodways and Ceramic Craft in the Late Formative Titicaca Basin

In her M.A. thesis, Sophie Reilly researched foodways of the Late Formative period (200 BC-300 AD) in the Lake Titicaca basin of highland Bolivia. She studied both the plant remains of food as well as the ceramic vessels in which food was prepared, stored, and consumed. In another McMaster lab, the Lab for Interdisciplinary Research on Archaeological Ceramics (LIRAC), Reilly studied ceramic attributes to learn about the technological choices that potters made while producing these vessels. In the MPERF, Reilly recovered microbotanical residues from the ceramic sherds to identify the plants that were present in the ceramic vessels. By studying both ceramics and food remains, Reilly explored the daily practices that went into preparing meals in the Late Formative Period.

Pleistocene and Early Holocene Social Landscapes in the South-Central Andes: A Paleoethnobotanical Contribution

Brett Furlotte investigated past landscape engagements as they related to subsistence practices and social organization at the Cuncaicha rockshelter, a multi-component archaeological site with Pleistocene and early Holocene dated cultural deposits in the Pucuncho Basin of southern Peru.  In the MPERF, he began to look for plant-related activities, including fuel, medicine, craft, and food and consumption. He initiated analyses in macrobotanical evidence of charred unidentified woody shrubs and grasses, parenchymous tissues indicative of starchy roots and tubers, and starch grain and phytolith residues recovered from sediments.

Storage and Pilgrimage at the Cerro del Convento Rock Shelter: Proyecto Arqueologico Nejapa Tavela (PANT), Oaxaca, Mexico

In this project, Shanti Morell-Hart and Éloi Bérubé investigated macrobotanical remains associated with a specialized feature in the rock shelter of the Cerro del Convento site, in the Sierra Sur region of Oaxaca. Examining the well-preserved macrobotanical remains helped to assess whether the rock shelter served as a functional storage space for agricultural goods, a temporary dry shelter and sleeping space for farmers working in their fields, or a sacred space that was a destination for pilgrimage and making petitions.

Paleoethnobotany, foodways, and offerings in the Mixteca de la Costa, Oaxaca, Mexico: Research on the archaeological sites of La Consentida and Cerro de la Virgen

Éloi Bérubé used paleoethnobotanical methods to analyze plant uses at two archaeological sites. The samples collected at La Consentida by Dr. Guy Hepp and his team came from different contexts, including grave goods. By identifying phytoliths and starch grains from artifacts dating from the Early Formative period, Bérubé illuminated plant uses in everyday lives and in the ritual and sacred realm. Éloi Bérubé also studied artifacts left as offerings at the Terminal Formative site of Cerro de la Virgen, where he examined the use of plants in sacred rituals. This research helped to indicate the potential for further paleoethnobotanical analysis on the site.
