Text-fig. 10.—A possible hunting set of Hell Creek theropods, drawn to scale. A, Tyrannosaurus rex. B, Albertosaurus lancensis. C, the Jordan theropod. D, Saurornithoides mongoliensis. S. mongoliensis is not present in the Hell Creek, but is used to represent those saurornithoidids and dromaeosaurids present and represented by isolated teeth. A fifth form, Paronychodon lacustris, also represented only by isolated teeth has not been included but was probably intermediate between the saurornithoidids and the Jordan theropod. in A new Theropod Dinosaur from the Upper Cretaceous of Central Montana
