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.
Coryphodon
Since the first fossil was found in Wyoming, the taxonomy of "Coryphodon" and its family have been in disarray — five described genera have been synonymized with "Coryphodon" and thirty-five proposed species have been declared invalid.
"Coryphodon" evolved from the Late Paleocene "C. proterus", one of the largest species found and the only one known from the Clarkforkian NALMA. The body size then decreased until "C. eocaenus" appears at the Clarkforkian-Wasatchian transition (55.4 Ma, near the PETM), from where "Coryphodon" evolved into the large species "C. radians". "C. radians" in its turn evolved into two contemporaneous species that appear in the Early Eocene, the small "C. armatus" and the very large "C. lobatus". These changes in size are thought to be linked to global climate change, with the size minimum in the "Coryphodon" lineage occurring shortly after Paleocene-Eocene boundary.
