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.
Zhucheng
On 31 December 2008, palaeontologists from the Institute of Vertebrate Paleontology and Paleoanthropology of Chinese Academy of Sciences announced they have unearthed 7,600 dinosaur fossils since March 2008 around Zhucheng. The latest sites to be discovered are near the towns of Longdu, Shunwang, Jiayue and Zhigou. The palaeontologists believe they have found one of the biggest sites of dinosaur remains from a massive excavation pit. The fossilized bones date to the late Cretaceous period just prior to the Cretaceous–Paleogene extinction event. The findings also include the remains of a 20-meter (66 ft) hadrosaurid, a record size for the duck-billed dinosaur. A fossilized skull of a large ceratopsian was also found along with bones which belong to club-tailed ankylosaurs.
