In 1997 Sotheby's secured a still-unequalled record of $8.4 million for a complete Tyrannosaurus Rex skeleton known as 'Sue,' which now resides in Chicago's Field Museum. Now Sotheby's Paris will bring to auction for the first time ever an Allosaurus above), which at over 30 feet (10 metres) long was the Tyranosaurus Rex of the Jurassic Period. It is joined by: a complete skeleton of a Plesiosaurus; a carnivorous fish; sparkling giant crystals; and a Prehistoric Woolly Rhinoceros. These quasi-mythical creatures have fascinated mankind since the 16th century, with connoisseurs and collectors vying to add them to their collections. Twentieth-century artists saw in them new sources of inspiration and experimentation. Over the past decade, France has held several auctions of these vanished giants, giving collectors the chance to make their childhood dreams come true by adding to their cabinet of curiosities, or collecting them as works of art.
