Las Superfamilias Sphaerioidea Deshayes, 1855 y Unionoidea Rafinesque, 1820 en yacimientos arqueológicos del sur de Iberia: implicaciones ecológicas

Abstract

This paper provides information on freshwater bivalve species of the Superfamily Sphaerioidea Deshayes, 1855 and Unionoidea Rafinesque, 1820 from seven archaeological sites in southern Iberia analyzed by the authors. All the information available in the literature on these species has been compiled, providing data from a further thirty-three localities. Overall, four species have been identified: Pisidium casertanum, Margaritifera margaritifera, Margaritifera auricularia, and Potomida littoralis in the sites studied directly, to which must be added the presence of Unio mancus, Unio delphinus and Unio tumidiformis as well as from collections deposited in museums. The specimens come from a chronocultural segment ranging from the Middle Palaeolithic to the Middle Ages. Furthermore, we provide information on the ecology and biology of the different species, as well as their relationship with other (interspecific) species within the ecosystem.
