Investigaciones arqueobotánicas en Mesoamérica y Centroamérica

A brief summary of published archaeobotanical studies and references to plant remains from archaeological sites in Mesoamerica and Central America is provided. followed by a discussion of the reasons for which this discipline has not developed significantly during the past 20 years in this area. It is concluded that the maior deterents to archaeobotanical research are the lack of sufficient trained personnel and the lack of any coherent concept of methods and goals to guide research

Aspectos ecológicos del desarrollo y la decadencia de Teotihuacan

Estudios recientes enfocados a aspectos ecológicos para la interpretación del desarrollo y caída de Teotihuacan hacen hincapié en la importancia que tuvo la simbiosis económica y la agricultura intensiva, especialmente en el uso de irrigación de cultivos.\ua

A geoarchaeological investigation of the Street of the Dead at the Tlajinga district, Teotihuacan, Mexico.

Archaeological investigations undertaken by the Proyecto Arqueológico Tlajinga Teotihuacán are focused on understanding urban expansion and household economies in this southern district of the city. Our geoarchaeological research addresses similar topics through examination of relevant microstratigraphic and botanical signatures as well as those relevant to reconstructing paleoenvironment. We investigated four different contexts at Tlajinga: the southern extension of the Street of the Dead, an obsidian working area outside Compound 17:S3E1, anthropogenic and natural layers below Compound 18:S3E1, and a soil profile at the San Lorenzo river. We employed micromorphological, pollen, and phytolith analyses as well as standard soil analytics to study the various deposits in these contexts. Our analysis demonstrates artificial lowering of the tepetate for continuing the axis of the Street of the Dead, microdebitage from obsidian working outside Compound 17:S3E1, and the preservation of in situ burning activities at Compound 18:S3E1. Further, we reconstruct alluvial infilling of the Street of the Dead with pedogenetic overprinting and present further evidence on the occurrence and variability of the Black San Pablo Paleosol and its agricultural significance

Algunas consideraciones sobre el uso prehispánico de recursos vegetales en la Cuenca del Alto Lerma

En este artículo se presentan algunos resultados del análisis de restos macrobotánicos recuperados de excavaciones en 6 sitios de 3 macrozonas en la cuenca del Alto Lerma: zona lacustre, plano aluvial y piedemonte. La identificación de algunas plantas dio como resultado que hubo una relativa continuidad en su uso en las 3 macrozonas. Dichos resultados proveen datos que dan base para la formulación de las hipótesis concernientes a la adaptación humana y la explotación de recursos
