KOKKELS UIT DE BAAI VAN SOÚRPI (GRIEKENLAND); INDICATOREN VOOR ZEEMILIEU EN BEVOLKINGSDRUK
Samenvatting
Mediterranean lagoonal cockles, Cerastoderma glaucum, from the Middle Bronze Age site of Magoúla Pavlína have much thicker valves than cockles of the same size from the Hellenistic town of New Halos and from slightly later dwellings near the southeast gate of the by then destroyed town of New Halos. The cockles from the large Hellenistic town of New Halos are significantly smaller (p) than the cockles from the Magaula Pavlína site and the later dwellings near the southeast gate. The thicker Middle Bronze Age valves must be due to a difference in environment: a lagoon, the optimum habitat of the species, in the Middle Bronze Age, as against estuaries and perhaps remnants of the former lagoon in the Hellenistic period. The difference in average size is explained by differences in the exploitation of the cockles: for the inhabitants of the large town of New Halos also smaller cockles were harvested.
