ABSTRACT The fragmentary skeleton of a new Late Cretaceous avialan theropod from Patagonia is described. Patagonykus puertai possesses caudal trunk vertebrae that are slightly convex caudally. The last sacral centrum is ball-shaped caudally, a condition that is also found in the caudal vertebrae. Caudal synsacral vertebrae are keeled ventrally.
