Sue (dinosaur)
Sue is the nickname given to FMNH PR 2081, which is the largest, most extensive and best preserved "Tyrannosaurus rex" specimen ever found, at over 90% recovered by bulk. It was discovered in August 1990, by Sue Hendrickson, an explorer and fossil collector, and was named after her. After ownership disputes were settled, the fossil was auctioned in October 1997, for US $8.3 million, the highest amount ever paid for a dinosaur fossil, and is now a permanent feature at the Field Museum of Natural History in Chicago, Illinois.
Crystal skull
The "Smithsonian Skull", Catalogue No. A562841-0 in the collections of the Department of Anthropology, National Museum of Natural History, was mailed to the Smithsonian Institution anonymously in 1992, and was claimed to be an Aztec object by its donor and was purportedly from the collection of Porfirio Diaz. It is the largest of the skulls, weighing and is high. It was carved using carborundum, a modern abrasive. It has been displayed as a modern fake at the National Museum of Natural History.
