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.
American Museum of Natural History
Most of the museum's collections of mammalian and dinosaur fossils remain hidden from public view. They are kept in numerous storage areas located deep within the museum complex. Among these, the most significant storage facility is the ten story Childs Frick Building which stands within an inner courtyard of the museum. During construction of the Frick, giant cranes were employed to lift steel beams directly from the street, over the roof, and into the courtyard, in order to ensure that the classic museum façade remained undisturbed. The predicted great weight of the fossil bones led designers to add special steel reinforcement to the building's framework, as it now houses the largest collection of fossil mammals and dinosaurs in the world. These collections occupy the basement and lower seven floors of the Frick Building, while the top three floors contain laboratories and offices. It is inside this particular building that many of the museum's intensive research programs into vertebrate paleontology are carried out.
