CHETUMAL, MEXICO.- A group of 14 small shell pendants discovered in funerary contexts along sections of the Maya Train project is offering archaeologists new clues about trade, technology and religious beliefs in the ancient Maya world.
The pendants, found in Campeche and Yucatán, depict frogs and toads and measure only between 2 and 4 centimeters. Despite their small size, researchers say they may help reveal how raw materials circulated across southeastern Mexico, where certain species were found, and how objects connected to water and fertility were used in ritual life.
The pieces were recovered during archaeological salvage work carried out by Mexico’s National Institute of Anthropology and History (INAH) and are now being studied at the Zooarchaeology Laboratory in Chetumal, Quintana Roo.
According to archaeologist María Elodia Acevedo Chin, the objects come from the archaeological sites of Sacamuy, Dzitbalché, Xiol, Kimbilá and Kanab and date to the Late Classic period, roughly AD 650 to 900.
For the Maya, frogs and toads carried powerful symbolic associations. Their close connection with water and rainfall made them important figures in ceremonies related to agriculture, fertility and renewal. They were also linked to the underworld and to ideas of rebirth.
"These objects not only had aesthetic value, but also embodied the sacred bond between human beings, nature and the spiritual world," Acevedo Chin said.
The choice of shell was itself significant. In ancient Mesoamerica, shell was prized both for its visual qualities and for its association with water. It could serve as a marker of social status, appear in ritual settings and be fashioned into jewelry, ornaments and musical instruments.
The pendants were carefully polished and decorated using grooved and incised techniques. Each has two conical perforations near the lower part of the body, suggesting they were designed to be suspended or worn.
Researchers have also identified two different ways of representing the animals’ heads. Some examples feature circular depressions for the eyes along with an incised mouth, while others show only the circular eye markings.
One particularly intriguing detail is the face-down position in which the animals are shown. Archaeologists believe this may echo an image in folio 17 of the Madrid Codex, where frogs or toads appear in association with falling rain.
The exact funerary significance of the pendants is still under investigation. Researchers do not yet know whether they were buried with adults or children, although similar objects found elsewhere in the region have been associated with child burials. That has led to the possibility that some may have been placed as offerings for deceased children.
Mexico’s Secretary of Culture, Claudia Curiel de Icaza, said the discovery demonstrates how even very small archaeological objects can reveal broader patterns of life in the past.
"Pieces measuring only a few centimeters can provide information about exchange routes, technical knowledge and the way ancient Maya communities understood their relationship with nature," she said.
The collection forms part of a broader group of shell materials recovered from different archaeological settings across the Maya region. Researchers hope continued study will clarify not only how the pendants were made and distributed, but also how long their symbolism persisted among communities in southeastern Mexico.
For Acevedo Chin, the discovery offers another opportunity to reconsider the connections linking trade, ritual practice and the natural world in ancient Maya society, while opening the way for further research into zoomorphic pendants throughout the region.
