Bayesian classification for dating archaeological sites via projectile points

2021

Dating is a key element for archaeologists. We propose a Bayesian approach to provide chronology to sites that have neither radiocarbon dating nor clear stratigraphy and whose only information comes from lithic arrowheads. This classifier is based on the Dirichlet-multinomial inferential process and posterior predictive distributions. The procedure is applied to predict the period of a set of undated sites located in the east of the Iberian Peninsula during the IVth and IIIrd millennium cal. BC.

A special body: Exposure ritual of a Bronze Age seated cadaver from the cemetery of Humanejos (Parla, Madrid, Spain)

2020

Abstract Seated positions are extraordinarily exceptional in prehistoric graves and despite the increasing number of new cases its social meaning remains uncertain. This paper presents a new finding of a Bronze Age seated burial discovered in the prehistoric cemetery of Humanejos (Parla). Such a unique burial is carefully analyzed in the context of the IInd millennium cal BC burial rituals. Firstly, the different phases of the inhumation were described through an archaeothanatological approach, which showed that the body was originally bound in a sitting position and then the upper part, which was exposed, naturally collapsed after the decomposition process. Furthermore, the biological feat…

The Chronology of Archaeological Assemblages Based on Automatic Bayesian Procedure: Eastern Iberia as Study Case

2021

The purpose of this work is to show an automatic Bayesian procedure to obtain accurate chronological information of archaeological assemblages characterized by palimpsest or neither radiocarbon dates and whose temporal information comes only from bifacial flint arrowheads.In this work, a classification based on the Dirichlet-multinomial inferential process and its posterior predictive probability distribution are applied. Its purpose is to predict the chronological period of archaeological assemblages (levels or sites) based on the predictive probability distribution of each bifacial flint arrowhead types defined in the Eastern Iberia during the 4th and 3rd millennium cal BC. The results of…
