Text-fig. 9.—Anterior portion of maxilla of the Jordan theropod (stippled) compared with the corresponding region of the maxillae of other tyrannosaurs. All reproduced to equal length from anterior end of maxilla to anterior margin of antorbital recess (this length in the actual specimens differs by less than 15 percent). A, Juvenile Tyrannosaurus rex. B, Albertosaurus lancensis. C, Juvenile Albertosaurus libratus (AMNH 5664).

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
