Deinonychus antirrhopus
Based on the few fully mature specimens, Deinonychus could reach 4 metres (13 ft) in length, with a a weight of 100 kg (220 lb). Its skull was equipped with powerful jaws lined with around sixty curved, blade-like teeth. Studies of the skull have progressed a great deal over the decades. Ostrom reconstructed the partial, imperfectly preserved, skulls that he had as triangular, broad, and fairly similar to Allosaurus. Additional Deinonychus skull material and closely related species found with good 3D preservation show that the palate was more vaulted than Ostrom thought, making the snout far narrower, while the jugals flared broadly, giving greater stereoscopic vision. The skull of Deinonychus was different from that of Velociraptor, however, in that it had a more robust skull roof like that of Dromaeosaurus, and did not have the depressed nasals of Velociraptor. Both the skull and the lower jaw had fenestrae (skull openings) which reduced the weight of the skull. In Deinonychus, the antorbital fenestra, a skull opening between the eye and nostril, was particularly large.
Moros intrepidus
Moros (meaning "impending doom") is a genus of tyrannosauroid theropod from the Late Cretaceous Cedar Mountain Formation of Utah. It contains a single species, M. intrepidus. The generic name is derived from the Greek Moros (an embodiment of impending doom), in reference to the establishment of the tyrannosauroid lineage in North America. The specific name is derived from the Latin word intrepidus ("intrepid"), referring to the hypothesized dispersal of tyrannosauroids throughout North America following Moros. Moros was a small-bodied, cursorial tyrannosauroid with an estimated weight of about 78 kg (172 lb) and a ~1.2-m limb length, M. intrepidus therefore ranks among the smallest Cretaceous tyrannosauroids. Moros represents the earliest known diagnostic tyrannosauroid material from the Cretaceous of North America by a margin of about 15 million years.
