On the Pacific shore of the Mexican state of Colima, waves and tides have washed onto the sand more than ninety objects created long before the arrival of Europeans. Residents of the village of Playa Tecuanillo in the municipality of Tecomán noticed ceramic bowls, fragments of female figurines and animal bones, after which they contacted the National Institute of Anthropology and History.
Specialists from the INAH center in Colima immediately launched rescue operations. Together with fishermen, local authorities and residents, they collected 38 artifacts during the first surveys in June 2026, and a further 66 objects were handed over by the residents themselves. Among the finds are nine intact bowls, sixteen fragments of anthropomorphic figurines, forty-seven potsherds and one possible bead.
Preliminary assessments date the materials to the period from the Middle Preclassic (1200–400 BCE) to the Postclassic (900–1521 CE). According to experts, the items belong to the cultures of western Mexico and are linked to the regions of central and north-central Mesoamerica. Later, dog bones and a thin-walled bowl dating to the Armería phase (500–1100 CE) were also found.
The reason the artifacts appeared on the surface is the constant erosion of the coastal strip. Strong waves, tides and hurricanes wash away the sand deposits that for centuries hid traces of ancient settlements. Similar finds had already been recorded in December 2025, when fishermen reported an eroded surface with materials from the Ortices, Comala, Colima and Armería phases.
All the objects have been handed over for storage to the INAH center in Colima. Research continues there, which should clarify the origin of the finds and provide new information about the lives of the people who inhabited the Colima coast in pre-Columbian times. Discoveries like these show how fragile the balance is between natural processes and the preservation of cultural heritage.
Each new fragment of pottery or bone becomes part of a mosaic from which scholars reconstruct a picture of ancient trade routes, rituals and everyday life. At the same time, the growing activity of the ocean is a reminder that many monuments may disappear before they can be studied.
The timely involvement of local residents and the institute's prompt work make it possible to preserve at least some of this evidence for future generations.
