Spending $45,000 on a single egg sounds like a cracked idea -- unless it's the largest egg in existence.
The supersized egg is 12 inches by 8 inches and belongs to the Elephant Bird, a giant bird that lived on Madagascar before going extinct sometime between the 13th and 17th centuries, KXAN-TV reported.
The completely fossilized egg, discovered by archeologists in the late 1800s or early 1900s, is being put upfor auction on April 24 by Christie's Auction House. It's been appraised at $45,000, but experts say it could sell for even more than that.
"It's very rare to find one that's complete. To see one in such perfect condition is a real treat," James Hyslop, a Scientific Specialist at Christie's, said according to the Independent.
The Elephant Bird stood up to 11 feet high and resembled a heavily-built ostrich. Its egg is 120 times bigger than a chicken egg.
"In fact, the egg is the largest egg ever laid by any animal. They are bigger than dinosaur eggs," Hyslop said, according to
For the record, the largest egg laid by a living bird weighed in five pounds and 11.35 ounces, according to Guinness. That egg was laid by an ostrich on a farm in Borlänge, Sweden in May 2008.
