“…Evidence for the presence of oyster shells was found in several sites along the Red Sea coast, whether in Marina Gawasis, Wadi al-Jarf, or Ain Sukhna, during the old kingdom (about 2613-2181 BC), the middle kingdom (2040-1782 BC), the new kingdom (about 1570-1069 BC), and the late period (525-332 BC), indicating the continued use of oysters until the end of the Ptolemaic period [16]. Large quantities of shells, snails, mussels, and fish were found in the Ptolemaic layers, indicating that these mollusks were used as food and a source of meat in these areas at the time [16]. Most oyster shells retained signs of burns on their outer surfaces, indicating that they were placed directly on the burning coals, as a method used today by "El-Ababda nomads", especially with a species of these shells known as Strombus tricorn, more than other kinds [16].…”
