Investigating food plant dynamics in household features from the Amerindian site El Flaco (11th to 15th century), Dominican Republic: macrobotanical and phytolith remains speaks out

El Flaco is an Amerindian site located in the northwestern part of the Dominican Republic and has been excavated by the ERC-synergy research project NEXUS 1492. El Flaco is a precolonial hamlet which was occupied between the 10th and 15th centuries AD. One of the goals of the NEXUS 1492 project is to gain new information about the human plant dynamics of the site. One way of investigating this is to conduct paleoethnobotanical analysis on hearth features in which food plants, fuel plants, and plant foods were processed, cooked, and consumed in different ways. The research described in this thesis consists of macrobotanical and phytolith analyses of five hearth features from El Flaco. The main aim of this research is to investigate which plant foods could have been part of the diet of the former inhabitants of El Flaco. With the macrobotanical analysis, only one taxon could be identified, which is Portulaca spp. This taxon is edible, but since it is a highly invasive plant, it was...Show moreEl Flaco is an Amerindian site located in the northwestern part of the Dominican Republic and has been excavated by the ERC-synergy research project NEXUS 1492.

The main aim of this research is to investigate which plant foods could have been part of the diet of the former inhabitants of El Flaco. With the macrobotanical analysis, only one taxon could be identified, which is Portulaca spp. This taxon is edible, but since it is a highly invasive plant, it was likely accidentally charred and not consumed. The results of the phytolith analysis showed that five taxonomic groups (six taxa) were likely consumed: Marantaceae/Cannaceae, Annonaceae, Cucurbitales (wild), Cucurbita spp. (domesticated), and Zea mays.Show less
