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.
Titanoboa
By comparing the sizes and shapes of its fossilized vertebrae to those of extant snakes, researchers estimated that the largest individuals of "T. cerrejonensis" found had a total length around and weighed about .
In 2009, the fossils of 28 individuals of "T. cerrejonensis" were found in the Cerrejón Formation of the coal mines of Cerrejón in La Guajira, Colombia. Before this discovery, few fossils of Paleocene-epoch vertebrates had been found in ancient tropical environments of South America. The snake was discovered on an expedition by a team of international scientists led by Jonathan Bloch, a University of Florida vertebrate paleontologist, and Carlos Jaramillo, a paleobotanist from the Smithsonian Tropical Research Institute in Panama.
The name "Titanoboa" means "titanic boa". The species epithet "cerrejonensis" refers to the Cerrejón coal mine and the Cerrejón Formation, in which the fossils have been found.
