“…In Mexico, salvage archaeology is a national priority, since this modality makes it possible to recover information that otherwise would be lost (Carballal Staedtler and Moguel Cos 2007:24). Therefore, there has also been research on mixed urban context materials recovered during salvage operations from Tlatelolco (Charlton et al 1995; Otis Charlton 1995), the Templo Mayor (Fournier 1998), the ex-Convento of San Jerónimo (Fournier 1990; Juárez Cossío 1989; Hernández Aranda 1980) (all in Mexico City), and the Palacio de Cortés and the Zócalo in Cuernavaca (Charlton et al 1987; Fournier and Charlton 2011), all of which show both the usefulness and the limitations of such collections, particularly for broad sweeping studies evaluating patterns of distribution and consumption through time and between different areas at the same time period (for example, Fournier 1990).…”
