Looking to start your own Jurassic Park? Sorry, but you wont find any dino DNA here. What you will find, however, is a one-of-a-kind Tyrannosaurs Skeleton ($950,000+; Auction). 75 percent complete overall — with an 80 percent complete skull — this massive fossil is 24 feet long, 8 feet tall, and is mounted elegantly on a gray-painted armature. The perfect piece to sit underneath your "When Dinosaurs Ruled the Earth" banner.
