A new ankylosaurian from the Late Cretaceous strata of Zhucheng, Shandong Province
-
Abstract
A new ankylosaurian dinosaur, Sinankylosaurus zhuchengensis gen.et sp.nov is described based on an almost complete right ilium recovered from the Upper Cretaceous Wangshi Group of Zangjiazhuang, Zhucheng, Shandong Province.It possesses the following characteristics: The length of preacetabular process is more than two-thirds of the whole ilium.The posterior (distal) of preacetabular process is wide, and the process of extending toward the proximal end is strongly constricted, with a wide gap between the anterior and posterior widths of preacetabular process.The discovery of this new ankylosaurian adds to the diversity of the Zhucheng dinosaur fauna and further demonstrates the similarity between the dinosaur assemblages of eastern Asia and those of North America.
