Resumo

A new small theropod dinosaur, documented by an incomplete skeleton and three frontals, is described from the Judith River Formation (Upper Cretaceous: Campanian) of south-central Alberta. It is distinguished from both Stenonychosaurus and Dromaeosaurus by the structure of the frontal and by the marginal dentition. It resembles Stenonychosaurus in the structure of the frontal and the Dromaeosauridae in the shape of the endocranial cavity and other skeletal features. The material is referred to a new genus and species of the Dromaeosauridae.
