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.
Museum of the Rockies
Apart from housing one of the largest collections of dinosaur fossils in the world and the largest in the United States, the museum is also home to one of the world's largest "Tyrannosaurus" skulls (MOR 008) – narrowly surpassing that of the Chicago Field Museum's specimen, Sue. The museum's Siebel Dinosaur Complex, designed by curator Horner, is home to one of the first identified female dinosaurs, an ovulating "T. rex". Curator Horner, who served as an adviser to the "Jurassic Park" films, was one of the lead scientists involved in the 2005 discovery of soft tissue remains in the thigh bone of a "Tyrannosaurus", which were later brought to the museum. The museum has also been involved in a number of other finds, including a baby "Triceratops" in Jordan, Montana, in 2006, and "Yoshi's Trike" (MOR 3027), a large "Triceratops" specimen with 125 cm long horns, discovered in 2010.
