Paris Monographs in American Archaeology 13 The site of Caseta in the Sayula Basin (Jalisco, Mexico) was discovered in 1992 and immediately became the focus for a rescue project because of its archaeological importance. Over the following seasons, the funerary assemblages took on an increased significance, representing as they did, finds from the Usmajac phase (300/400 BC) to the Amacueca (1100-1500 AD), and by way of their differences from the usual characteristic features of the vicinity. Analysis of this funerary material revealed socio-cultural as well as archaeo-biological insights into the populations over a relatively long period before the hispanicisation of the Sayula Basin. Chapters 1 & 2 are devoted to a general overview of the region and the site. Chapters 3-5 detail the finds. The cultural and biological nature of the finds are discussed in Chapters 6 & 7, while Chapters 8 & 9 concentrate on comparative studies and synthesis.
