The study carried out by the Universitat Jaume I, the Municipal Archaeological Museum of Cartagena, the Provincial Council of Castellón and the University of Barcelona confirms that its use during the Mesolithic period was greater than previously thought.
New discoveries and material reviews by an inter-institutional research team have confirmed that the economic context at the end of the transition between the Pleistocene and the Holocene on the Mediterranean coast were richer, more complex and more varied than was previously thought. The exploitation of marine resources was not limited to the harvesting of molluscs, but also included fishing, although not many remains have been preserved, probably because the preservation of these types of materials is more delicate or because of the eating habits of ancient human populations.
Until a few years ago, little was known about the characteristics of the economy of hunter-gatherer groups in the Mediterranean during the transition from the Pleistocene (the glacial era, the Palaeolithic) to the Holocene (post-glacial, the time we live in today). Most of the studies carried out in the Iberian Peninsula suggested that the sites of marine exploitation were located particularly in the Cantabrian and Atlantic area, but the new data and studies provided by the research team can change this paradigm.
The research and analysis work, whose conclusions have been published in The Journal of Island and Coastal Archaeology, has involved Dídac Román, doctoral researcher of excellence of the GenT Plan of the Valencian Regional Government in the Department of History, Geography and Art at the Universitat Jaume I and the Pre-EINA research group; Miguel Martínez Andreu from the Municipal Archaeological Museum of Cartagena; Gustau Aguilella from the Archaeological and Prehistoric Research Service of the Castellón Provincial Council and Josep Maria Fullola and Jordi Nadal from the Prehistoric Studies and Research Seminar (SERP) of the University of Barcelona.
Data collected during the research confirm that the use of marine resources during the late Palaeolithic and Mesolithic on the Iberian Mediterranean coast was clearly more common than was previously thought with the data available at the time. The difference regarding the presence of less evidence than in the case of the Cantabrian and Atlantic coasts, where there are more hunter-gatherer-fisherman sites catalogued, could be due to different reasons: greater richness and diversity of life due to the cold marine currents, more abundant in nutrients; presence of tides and other environmental factors and better preservation of the sites over time thanks to a coastal platform and a steeper coastline that protected them from the progressive flooding of the environment with the melting of the poles during the Holocene.
