Dinosaur city
Zhucheng has been an important site for dinosaur excavation since 1960. The local community is known to use calcium rich fossils for traditional village remedies used to treat muscle cramps and other minor ailments. The world's largest hadrosaurid fossil was found in Zhucheng in the 1980s and is on display in the local museum. Scientists have collected more than 50 MT of fossils since 1960. The city has also been a place for smuggling of dinosaur bones; in January 2008, Australia returned hundreds of kilograms of Chinese dinosaur fossils, including dinosaur fossil eggs. These fossils were recovered during a sting operation carried out on warehouses and cargo containers.

The ceratopsian Zhuchengceratops (2010), sauropod Zhuchengtitan (2017) and theropod Zhuchengtyrannus (2011) have been described from deposits near and named after Zhucheng.

2008 discovery
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 Late Cretaceous just prior to the Cretaceous–Paleogene extinction event. The findings also include the remains of a 20 m 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.

According to Professor Zhao Xijin, a palaeontologist in charge of the excavations from the Institute of Vertebrate Paleontology and Paleoanthropology, "This group of fossilised dinosaurs is currently the largest ever discovered in the world... in terms of area."

Such a high concentration of fossil bones in such a small area is significant for the theories of extinction of dinosaurs. A detailed scientific journal on the fossils is expected to be published later in 2009. Excavations are currently suspended for the winter but will resume when the weather gets warmer. Scientists believe a volcanic eruption may have killed the dinosaurs, and a subsequent flood carried the fossils to Zhucheng, which may have been a wetland covered in grass.

The local authorities in Shandong are making plans to set up a fossil park in the area.
