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.
Aegirocassis
Aegirocassis is an extinct genus of anomalocarid arthropod belonging to the family Hurdiidae that lived 480 million years ago during the early Ordovician. It is known by a single species, Aegirocassis benmoulai. A fossil of "A. benmoulai" from the Fezouata biota, Morocco was discovered by and named after Mohamed Ben Moula, a fossil collector who recognized its rare characteristics and brought it to the notice of a professional paleontologist, Peter Van Roy, at the Ghent University in Belgium. 
Van Roy initiated scientific study of the fossil, the earliest known of a "giant" filter-feeder discovered to date. "Aegirocassis" is considered to have evolved from early predatory anomalocarids. At the time of its existence, "A. benmoulai" was possibly the largest animal in the world. The length was described as exceeding in the scientific journal "Nature".
