Name: Planicoxa.
Phonetic: Plan-e-coks-ah.
Named By: Tony DiCroce‭ & ‬Kenneth Carpenter‭ ‬-‭ ‬2001.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Dinosauria,‭ ‬Ornithischia,‭ ‬Ornithopoda,‭ ‬Iguanodontia,‭ ‬Ankylopollexia.
Species: P.‭ ‬venenica‭ (‬type‭)‬.
Diet: Herbivore.
Size: Estimated about‭ ‬6‭ ‬meters long.

Time period: Barremian of the Cretaceous.
Fossil representation: Remains of several individuals.

       A medium sized iguanodontid,‭ ‬dinosaur from the early Cretaceous of the USA,‭ ‬Planicoxa is established upon the partial remains of several individuals.‭ ‬As an iguanodontid,‭ ‬Planicoxa would have been a primarily quadrupedal dinosaur,‭ ‬though one with the capability to rear up and walk on just its hind legs when it needed to.‭ ‬Planicoxa would have also likely had a hardened keratinous beak to the front of its mouth so that it could easily crop mouthfuls of vegetation from plants.‭ ‬A second species of Planicoxa created from fossils previously assigned to Camptosaurus and named P.‭ ‬depressa,‭ ‬has now been removed and used to establish the genus Osmakasaurus in‭ ‬2011.
       Hailing from the Cedar Mountain Formation,‭ ‬Planicoxa may have been hunted by the larger predators of the time like Utahraptor and the huge Acrocanthosaurus.‭ ‬Smaller predators such as Deinonychus may have also posed a threat,‭ ‬especially if some of the theories about pack hunting dinosaurs are correct.
