Dinosaur size
There were larger dinosaurs, but knowledge of them is based entirely on a small number of fragmentary fossils. Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive titanosaur "Argentinosaurus huinculensis", which is the largest dinosaur known from uncontroversial evidence, estimated to have been and long. Some of the longest sauropods were those with exceptionally long, whip-like tails, such as the "Diplodocus hallorum" (formerly "Seismosaurus") and the 33- to 35-metre-long (108–115 ft) "Supersaurus". The tallest was the "Brachiosaurus".
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.
