During the Iron Age, funerary culture in Western Europe is characterised by a combination of unique practices. Cremation necropolis is the most common funerary treatment, which cohabitated with exhibition of decapitated skulls, and perinate burials in urban contexts. Regarding the latter, many questions remain to be answered; were the perinatal individuals buried within urban contexts deliberately selected as it is likely there are not enough to represent all of theindividuals who would have likely died at this age. The archaeological site of Alorda Park (Calafell, Catalonia) was occupied from the 6th to 2nd century BC. Three phases deeply remodelled the settlement that transformed it from a typical rounded plan settlement to a fortified and squared plan one. All these changes caused stratigraphic alterations thus, most of the excavated individuals (MNI=17) are only partially preserved. From them, only 7 have been exhumated in situ, six of them in the chieftain’s house and belonging the last phase. Here, we present a perinate, individual ALP’01 S.08, who presents several anatomical anomalies: cervical ribs and a supernumerary tooth germ fused to the germ of the left mandibular lateral deciduous incisor. This individual is analysed through a multidisciplinary approach to better understand the reasons of the specific funeral practice it underwent. Indeed, ALP’01 S.08 is very well preserved and was found under a paved street. An analysis of the double fused incisor germ using synchrotron microtomography (scan resolution: 3μm) and virtual histology techniques has shown an accentuated line compatible with the neonatal line, confirming that ALP’01 S.08 survived beyond birth. The paleo-genetic analysis have allowed to determine the sex and a micro-CT (μCT) scan analysis of the bones presenting paleopathological signs allows us to propose a complex differential diagnosis including syndromes with congenital, micro-nutrient defiency or as the result of environmental factors affecting development.< Réduire
