Alamosaurus
Alamosaurus (; meaning "Ojo Alamo lizard") is a genus of titanosaurian sauropod dinosaurs, containing a single known species, Alamosaurus sanjuanensis, from the late Cretaceous Period of what is now southern North America. Isolated vertebrae and limb bones indicate that it reached sizes comparable to "Argentinosaurus" and "Puertasaurus", which would make it the largest dinosaur known from North America. Its fossils have been recovered from a variety of rock formations spanning the Maastrichtian age of the late Cretaceous period. Specimens of a juvenile "Alamosaurus sanjuanensis" have been recovered from only a few meters below the Cretaceous-Paleogene boundary in Texas, making it among the last surviving non-avian dinosaur species.
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.
