Zhuchengosaurus maximus

For thirty four years Shantungosaurus reigned supreme as the largest known ornithiscian and biggest hadrosaur then—BAM!—along came Zhuchengosaurus maximus and knocked its crown off. If you're going to be stealing thunder you really need to be over sixteen meters long and as heavy as three elephants, but several notable similarities between the two, as well as their discovery in the exact same area, was always likely to raise the odd issue.

Known from the remains of several individuals including skull bones, limb bones, and vertebrae found in Shandong, China, Zhuchengosaurus was revisited by Ji, Wang and Liu in 2011 who came to the conclusion that its supposedly unique features were merely growth-related and it simply represents an older specimen of Shantungosaurus. Funnily enough, no sooner had they published their results than Zhao Xijin, Wang Kebai and Li Dunjing named an even bigger saurolophine Huaxiaosaurus, and that was found in exactly the same area too.
Etymology
Zhuchengosaurus combines "Zhucheng" (a City close to its discovery in China's Shandong Province) with the Greek "sauros" (lizard).
The species epithet, maximus, refers to its great size. It's Latin, you know?
