Stellasaurus ancellae Skiphosoura Length 72mmStellasaurus ancellae was a centrosaurine ceratopsid dinosaur from the Late Cretaceous of North America, known from remains recovered from the Two Medicine Formation in Montana, United States. Formally described in 2020 by Wilson, Ryan, and Evans, this taxon represents a particularly interesting form within the evolution of Campanian centrosaurines, as it combines anatomical traits seen in forms such as Styracosaurus, Einiosaurus, and Achelousaurus.
