Sauroposeidon
The press release in 1999 immediately garnered international media attention, which led to many (inaccurate) news reports of "the largest dinosaur ever!". While "Sauroposeidon" likely represents the tallest known dinosaur taxon, it does not hold records for either the longest or most massive. "Patagotitan" or "Argentinosaurus" make better candidates for the title "World's Largest Dinosaur" (presuming to ignore, as is conventional, "Amphicoelias"), though incomplete fossil evidence makes exact rankings impossible.
Dinosaur 13
The film depicts events that began in 1990, when American paleontologist Sue Hendrickson working with Pete Larson and his Black Hills Institute of Geological Research team discovered the largest and most complete "Tyrannosaurus rex" skeleton ever found (nicknamed "Sue") while digging in the badlands near Faith, South Dakota. The skeleton was seized from the institute by the federal government, followed by a 10-year-long battle with the FBI, the National Park Service, the Bureau of Indian Affairs, and Maurice Williams, the landowner on whose property the bones were discovered. Pete Larson also spent 18 months in prison, on unrelated charges of international money laundering and trading fossils on the black market.
