Souvenir shops in South Africa are full of lamps made out of ostrich eggs. The eggs are so big and strong that you can carve and cut intricate designs into their shells. The egg's contents are emptied through a hole and a bulb can be inserted instead, casting pretty shadows on walls and ceilings. The results are a big draw for modern tourists, but ostrich eggs have a long history of being used as art in South Africa. The latest finds show that people were carvings symbolic patterns into these eggs as early as 60,000 years ago.
Pierre-Jean Texier from the University of Bordeaux discovered a set of 270 eggshell fragments from Howieson Poort Shelter, a South African cave that has been a rich source of archaeological finds. Judging by their patterns, the fragments must have come from at least 25 separate eggs, although probably many more.
