First evidence of hippopotamus ivory exchange networks in north-eastern Iberian Peninsula: The object of Bòbila Madurell (Barcelona, Spain)

Abstract

This study examines a Late Neolithic-Chalcolithic ivory object (Véraza facies) found at the Bòbila Madurell settlement (Sant Quirze del Vallès, Barcelona, Spain). The main objective was to date the object and determine the provenance of the raw material. The radiocarbon analysis places it in the second quarter of the 3rd millennium BC. FTIR analysis identified it as hippopotamus ivory, marking the first and currently the oldest discovery in north-eastern Iberia. While most Iberian ivory is attributed to Asian or African proboscideans, hippopotamus ivory is known in southern Iberia during the Chalcolithic and Early Bronze Age, reflecting emerging trade networks from the Near East and Africa. Though the object is fractured, the archaeological context, together with morphological and residue analyses, suggests a possible use in textile work.
