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.
Timeline of United States discoveries
Torosaurus was a herbivorous dinosaur that lived during the Late Cretaceous Period about 70 million years ago in what is now North America. Torosaurus had an enormous head that measured 8 feet (2.5 m) in length. Its skull is one of the largest know up to date, no other land animal has ever had a skull larger than Torosaurus. Torosaurus frill made up about one-half the total skull length. The first fossils of Torosaurus were discovered in 1889, in Wyoming by John Bell Hatcher. The American paleontologist Othniel Charles Marsh would later name the specimen "Torosaurus latus", in recognition of the bull-like size of its skull and its large eyebrow horns. Ever since, the specimen has been in display at the Peabody Museum in New Haven, Connecticut.
