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.
Carnegie Museum of Natural History
The museum gained prominence in 1899 when its scientists unearthed the fossils of "Diplodocus carnegii". Today its dinosaur collection includes the world's largest collection of Jurassic dinosaurs and its "Dinosaurs in Their Time" exhibition offers the third largest collection of mounted, displayed dinosaurs in the United States (behind the Smithsonian's National Museum of Natural History and the American Museum of Natural History). Notable specimens include one of the world's only fossils of a juvenile "Apatosaurus", the world's first specimen of a "Tyrannosaurus rex", and a recently identified species of oviraptorosaur named "Anzu wyliei".
