Eight ostrich eggs believed to be more than 4,000 years old were found near a bonfire site in Israel.
A prehistoric campsite used by desert nomads was discovered beneath the sand dunes at Nitzana in the Negev region, the Israel Antiquities Authority reported.
The head of the excavations said that archaeologists also found stone tools and broken pieces of vessels, but eggs were really "a special discovery". Wild ostriches were common in this area throughout the 19th century.
"It's interesting because wild ostrich eggs are not uncommon in archaeological finds, but no bones were found. This may indicate that in the ancient period, people avoided catching ostriches and were satisfied with the eggs," said a representative from the Israeli institution.
The proximity of the eggs to the fire place indicates that they were collected and used as food. The eggs were crushed but well preserved due to being covered by sand as well as the dry climate which helped in their good condition.
These heavy birds have been found in archaeological sites at different times. They were not only used as a source of food (one ostrich egg is equivalent to 25 chicken eggs in terms of nutritional values), but also as means of transportation in funerals, in decorated objects with carvings and paintings or to hold water
