Summary Description:
Monagrillo (He-5) is a well-known archaeological site in tropical America. It is located near the marine shore of Parita Bay, a mangrove-fringed embayment, which is the most north-westerly portion of the much larger Panama Bay in the Pacific Ocean. Today it is a small elevated area ensconced within a fishing village and about 2 km inland from the active marine shore. It is in a very precarious conservation environment. It is known in local parlance as the “cerrito de conchas” on the outskirts of the expanding village of Boca de Parita, which is actually a few kilometers eastward from the town of Monagrillo. When the site was first used as a human settlement about 5000 years ago, it was located right on the active shore. From that moment on, riverine sedimentation coupled with aeolian (wind-blown) deposition gradually edged the active shore eastwards through the process of coastal progradation. Sediment core data obtained in 1979 show that, by about 3000 years ago (950 BCE), the ancient cluster of dwellings was surrounded by Rhizophora mangroves rendering the location barely habitable. Monagrillo was first located in 1948 by Gordon R. Willey and Charles R. McGimsey on a brief survey of coastal sites in Herrera Province during a Smithsonian-National Geographic project centered on sites further inland with mounds and polychrome ceramics (“Coclé), and directed by Matthew Stirling. Willey and McGimsey noted that the plain and monochrome pottery, decorated occasionally with incised and red-zoned designs, was radically different from the painted wares already described at sites in the adjoining region (now known as Gran Coclé) during the period of polychrome ceramics development). Radiocarbon chronology was not available at that time. Nevertheless, they proposed that the Monagrillo ware was older than other regional pottery complexes since it stood out as technologically and morphologically very different. Also, some of the grinding-stones were very similar to others found by McGimsey at Cerro Mangote across the Santa María River in Coclé Province. This site did not have pottery in the deepest strata and was classified as Preceramic. These archaeologists returned the dry season of 1952. They made a contour map, and excavated a much larger area with long trenches and some 3x3 m and 3x2 m pits. The strata were recovered with 10 cm and 50 cm levels irrespective of the complex stratigraphy. Sieves were used only once. For this reason, the numbers of vertebrate remains recovered was very low (261 elements). Shells collected as column samples, however, were analyzed quite thoroughly by Robert Greengo. Their vertical fluctuations in the mounded area were related appositely by the archaeologists to their interpretation of the site’s position vis-à-vis the marine shore. They used air photographs to reinforce their proposal, which has stood the test of more recent geomorphological work. After the excavations had terminated, careful profile drawings were made. The finds from Monagrillo were presented by Willey and McGImsey in a monograph: Willey, Gordon R. and C.R. McGimsey, III,1954. The Monagrillo Culture of Panama. Papers of the Peabody Museum of Archaeology and Ethnology 49(2). Harvard University Press, Cambridge. In the 1975, Olga Linares and Tony Ranere re-visited Monagrillo where they excavated two pits (4 m2 and 1.5 m2). They added ten radiocarbon dates to the one analyzed by Edward Deevey in 1959 )from a 1954 charcoal sample): 2140 ± 70 BC (2880 [2610] 2460 cal BP). They referred the beginning of the human occupation on a sand-bar subject to wave action to ~3000 BC. Intermittent occupation ensued until ca.1950 cal BC followed by a span of more frequent or denser use up to cal. 1500 BC when the enlarging high tidal flat (“albina” [not “alvina”]) began to make life uncomfortable (the trade wind in this area of Panama is extremely strong for four months, desiccates the landscape quickly and creates an increasingly dusty and salt-laden atmosphere as the albina expands. Fumie Iizuka returned briefly to Monagrillo in search of intact sediments for her instrumental study of Monagrillo pottery, but did not find reliably intact sediments. When first studied in 1948-52, Willey and McGimsey surmised that Monagrillo’s inhabitants were primarily shellfish-gathers who also collected wild plant foods, hunted deer and peccary, and occasionally fished. They admitted that some agriculture may have been practiced, but in an “incipient” way. The 1975 tests produced frequent carbonized fragments of the American oil pam (Elaeis oleifera) and the wine palm (Acrocomia mexicana). The former species clusters near seasonal freshwater swamps. Maize and manioc starch was found on Monagrillo’s edge-ground cobbles while at the nearby site of Zapotal )(Pr-32), considerably larger than Monagrillo (He-5), starch grains from arrowroot, two American yams and pepper (Capsicum) were reported in addition to maize and manioc . Ranere and Linares used nested sieves with mesh size down to window-screen (2 mm) which resulted predictably in the recovery of a very large sample of fish remains. These were analyzed by Richard Cooke in the 1970s (for a summary of the ten most frequent fish species, see Cooke, R.G, 1992. Prehistoric near-shore and littoral fishing in the eastern tropical Pacific: an ichthyological evaluation. World Archaeology 6: 1-49); a detailed list of the fish taxa recovered over 1/8” mesh [3.2 mm) is available). For her Temple U. Master’s Thesis, Patricia Hansell analyzed mollusc remains from a 0.3 m2 column sample. She found a relationship between taxa and sedimentation processes that was broadly similar to the one proposed by Greengo: decreases in the decline of clams (Tivela byronensis) from a high-energy marine edge environmental overlapping with increases in oysters (Ostrea) as the albina grew seawards and a saline lagoon formed alongside the site. Monagrillo was likely to have been primarily a fishing village, which may have served inland sites such as Zapotal and the Cueva de los Ladrones with salted and dried fish. It can be considered a precursor of later sites such as the Vampiros shelters at the mouth of the Santa María River in Coclé province.
