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.
Eurypterid
The eurypterids include the largest known arthopods ever to have lived. The largest, "Jaekelopterus", reached in length. Eurypterids were not uniformly large and most species were less than long; the smallest eurypterids, "Alkenopterus" and "Eocarcinosoma", were only long. Eurypterid fossils have been recovered from every continent. A majority of fossils are from fossil sites in North America and Europe because the group lived primarily in the waters around and within the ancient supercontinent of Euramerica. Only a handful of eurypterid groups spread beyond the confines of Euramerica and a few genera, such as "Adelophthalmus" and "Pterygotus", achieved a cosmopolitan distribution with fossils being found worldwide.
