Sinankylosaurus zhuchengensis Sinankylosaurus

Sinankylosaurus (meaning “Chinese fused lizard”) is a dubious dinosaur genus known from the Late Cretaceous Hongtuya Formation of China. The genus contains a single species, Sinankylosaurus zhuchengensis, known from a partial right ilium (a pelvic bone). This specimen was originally described as belonging to an ankylosaur, although later research has disputed this identification, noting the lack of anatomical characters uniting Sinankylosaurus with this group.
