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.
Krukowski Quarry
The most prominent fossils found at the quarry are scyphozoan medusae (true jellyfish) ranging in diameter from 50-70 centimeters, the largest jellyfish in the fossil record; these were initially discovered in 1998 by Dan Damrow, who published with paleontologist James Hagadorn. Paleontologists have also discovered slug- and mollusk-like climactichnites, as well as fossilized trackways of anthropods (including protichnites and diplichnites), and stromatolites including elephant skin, sand-chips, and domal sand stromatolites.
