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.
Amphibian
The smallest amphibian (and vertebrate) in the world is a microhylid frog from New Guinea ("Paedophryne amauensis") first discovered in 2012. It has an average length of and is part of a genus that contains four of the world's ten smallest frog species. The largest living amphibian is the Chinese giant salamander ("Andrias davidianus") but this is a great deal smaller than the largest amphibian that ever existed—the extinct "Prionosuchus", a crocodile-like temnospondyl dating to 270 million years ago from the middle Permian of Brazil! The largest frog is the African Goliath frog ("Conraua goliath"), which can reach and weigh .
