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.
Dinosaur
There were larger dinosaurs, but knowledge of them is based entirely on a small number of fragmentary fossils. Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive "Argentinosaurus", which may have weighed to  kilograms (90 to 110 short tons) and reached length of ; some of the longest were the long "Diplodocus hallorum" (formerly "Seismosaurus"), the long "Supersaurus" and long "Patagotitan"; and the tallest, the tall "Sauroposeidon", which could have reached a sixth-floor window. The heaviest and longest dinosaur may have been "Amphicoelias fragillimus", known only from a now lost partial vertebral neural arch described in 1878. Extrapolating from the illustration of this bone, the animal may have been long and weighed kg ( lb). However, as no further evidence of sauropods of this size has been found, and the discoverer, Edward Cope, had made typographic errors before, it is likely to have been an extreme overestimation.
