Paraná Delta comprises a large wetland macrosystem (Malvarez 1999). Its current geomorphologicalconfiguration was established after the last transgressive mid-Holocene event c. 6000 14C yr BP (Cavallottoet al. 2005). In this environment, a high ecological heterogeneity, with diverse and abundant tropical andtemperate biota, was developed. These features were important factors to the human colonization (Castiñeiraet al. 2017) registered at least from circa 2000 14C yr BP according to several dates performed in LATYRArgentinalaboratories. Dates proceed from various archaeological localities and were obtained from humanand faunal remains, mollusk shells, charcoal and organic matter samples. The archaeological contexts fromthis dates is related with Goya Malabrigo (Politis y Bonomo 2012) archaeological entity, associated with thesouthernmost spread of agriculture and earth engineering (Bonomo et al. 2011, Castiñeira et al. 2017). Thedates compiled in this work were essential to model the strategies involved in the settlement pattern andfunerary practices of Parana Delta prehispanic populations (Castro y Castiñeira 2018, Scabuzzo y Van Rap2017). In this contribution we systematize this chronological dataset in order to analyze the chronologicalrange associated to the delta human occupation process. We also explore the temporal relations with earthmound building and earth-mound linked burial practices. At the moment we consider a continuous occupationof the area without significate gaps in the sequence. However the disparity between mound building earlydates and human burial data should be more deeply explored.
