Marilyn Masson is an Associate Professor in Anthropology at the University at Albany –SUNY. Her research focuses on ancient economies of the Maya area, with recent emphases on household archaeology and the urban organization of Mayapán, the largest Maya political capital of the Postclassic Period. She is the author/editor of three books, including In the Realm of Nachan Kan (2000), Ancient Civilizations of Mesoamerica (2000, with Michael E. Smith), and Ancient Maya Political Economies (2002, with David A. Freidel). She has served as Principal Investigator on two major archaeological research projects, including the Belize Postclassic Project (1996-2002) and the Economic Foundations of Mayapan Project, which is co-directed by Carlos Peraza Lope and Timothy S. Hare (2001-present, supported by the National Science Foundation and the National Geographic Society). Currently, Masson’s collaborative research at Mayapán examines occupational heterogeneity, affluence, and modes of governance within the city’s neighborhoods. Marilyn received her doctoral degree at the University of Texas – Austin in 1993. She is a zooarchaeologist and lithic analyst and is also interested in the archaeology of religion. Her forthcoming book, “Ancient Urban Life at Mayapan,” Yucatan (University of Colorado Press, co-authored with Carlos Peraza Lope) documents greater complexity and integration in the political, social, and religious life of this political capital, and presents evidence for urban planning and administration.

He also directs the Kentucky Center for Geospatial Education, Research, and Outreach and manages the Kentucky Height Modernization Program.


Dr. Bradley Russell directed the three year Mayapán Periphery Project, documenting roughly 2 km2 of previously unrecorded terrain located outside of the massive fortifications which ring much of the site.  The study involved extensive mapping, excavation and soil sampling aimed at establishing the chronology and function of all features detected.  The new data suggest that some 17,000 people were present at the site, rather than the 12,000 person population estimate that has been widely used since 1962.  The estimated site size more than doubled from 4.2 sq km to between 8.8 sq km (map) and 10.1 sq km (map).  The site-wide spatial distribution and function of, residential settlement zones, economic production activities, the road system, administrative architecture and ritual architecture are all explored in detail.  The study identified key settlement zones and segregated economic production zones for agricultural produce, livestock and large scale lime plaster production located outside of the site’s fortifications.  This work contributes to the anthropological study of ancient urbanism and adds to a very robust and growing data set on the site’s overall organization.  The results of this work were published in 2008 as his doctoral dissertation, Postclassic Maya Settlement on the Rural Urban Fringe of Mayapán, Yucatán, Mexico and are available online at no cost at:

Stan Serafin, Project Bioarchaeologist

Stan Serafin

In 2003, I began analyzing the human skeletal remains from Mayapan excavated by the Carnegie Institution of Washington, Cliff Brown, Proyecto Mayapan, and the Economic Foundations of Mayapan Project for my dissertation, which I completed in 2010 in the Department of Anthropology at Tulane University. I found relatively high frequencies of healed cranial trauma in males, several cases of perimortem depressed cranial fractures, penetrating rib wounds and trophy-taking, and an embedded arrow head, lending support to colonial accounts of frequent warfare and social strife. Dental metric and nonmetric analyses demonstrated a relatively heterogeneous population compared to Classic period sites of the southern lowlands. Ongoing research is addressing nutritional and disease stress in different sectors of the population.

I have been part of the Proyecto Económico de Mayapan through multiple seasons; initially as a laboratory analyst in 2004, then as a suboperation co-director at the H-15 zona de entierros in 2008, and returned during a brief analytical season in February of 2010 to analyze materials from the 2009 field season. I also participated in the Proyecto Mayapan 2005. Most of my publications and conference presentations, including my master's paper and resulting article, have focused on the local metalworking industry at Mayapan. Other publications and presentations on Mayapan materials focused on lithic and shell debitage as specialized craft industries. I also pursue topics such as household craft production and craft specialization, exchange networks at multiple scales, and the spatial organization of urban economies in my doctoral dissertation, focused on the sites of Moxviquil and Huitepec, located in highland Chiapas near the modern city of San Cristóbal de Las Casas.


I first visited Mayapán in 1990. I went to study the houselot walls as I was working to formulate my doctoral dissertation research. At the time, the site was largely overgrown and even a little difficult to find. I returned the next year to excavate and stayed for two years, living in the nearby village of Telchaquillo. I later came down and helped out, intermittently, for a couple of seasons during Marilyn Masson’s SUNY Albany project. In the interim, Carlos Peraza of México’s National Institute of Anthropology and History excavated many of the monumental structures in the site center, and the government built a big new road to the site. In 2005, I directed a preliminary archaeological survey of the area around Mayapán to study the settlement patterns. Although I haven’t worked at Mayapán for several years now, I still return to visit my godchildren and compadres in Telchaquillo. I am currently Associate Professor Anthropology at Florida Atlantic University, in Boca Raton, Florida.

I have been working at Mayapán in association with the PEMY project since 2009. In 2009 I analyzed ceramic standardization of three of the most common ceramic wares found within the site. The data from that season is the basis for my University at Albany Master’s paper entitled: Standardization and Diversity of Pottery Wares at Mayapán. I am currently continuing research at Mayapán for my dissertation research. My dissertation will examine the local and regional environment and the distribution and management of agricultural resources and resources for specialized production at Mayapán.
