A large reconstructed Elephant Bird Egg (Aepyomis Maximus)
A large flightless bird from the Island of Madagascar, thought to have become extinct in the 17th century. Growing up to 11ft. (3.35m) in height, is was probably the heaviest bird to have existed. It is possibly the source of the "Roc" in Sinbad's tales and from the journeys of Marco Polo, and although reported in the 1650's, no European sighting are recorded. Sub fossilised eggs are occasionally found, especially in the Southern part of the island, although whole examples are rare.
