Planicoxa is a genus of advanced iguanodontian dinosaur from the Early Cretaceous of North America. It is known from the partial skeletons of several individual specimens. Its fossils were discovered in Utah, United States.
The type species for the genus is Planicoxa venenica, first described by Tony DiCroce and Kenneth Carpenter in 2001. Its discovery was made in the Poison Strip Sandstone Member of the Cedar Mountain Formation in Grand County, Utah, United States. The generic name, Planicoxa, which means “flat hip”, refers to the flat appearance of the ilium formed by horizontal folding over of the postacetabular process (rear portion of the ilium), the defining characteristic of the genus; venenica, the specific name, is Latin for “poison” in reference to the Poison Strip Sandstone Member of the Cedar Mountain Formation where the discovery was made.
