Daspletosaurus torosus
While very large by the standard of modern predators, Daspletosaurus was not the largest tyrannosaurid. Adults could reach a length of 8–9 meters (26–30 ft) from snout to tail. Mass estimates have centered on 2.5 t (2.5 long tons; 2.8 short tons), but have ranged between 1.8 and 3.8 t (1.8 and 3.7 long tons; 2.0 and 4.2 short tons). Daspletosaurus had a massive skull that could reach more than 1 meter (3.3 ft) in length. The bones were heavily constructed and some, including the nasal bones on top of the snout, were fused for strength. Large fenestrae (openings) in the skull reduced its weight. An adult Daspletosaurus was armed with about six dozen teeth that were very long but oval in cross section rather than blade-like. Unlike its other teeth, those in the premaxilla at the end of the upper jaw had a D-shaped cross section, an example of heterodonty always seen in tyrannosaurids. Unique skull features included the rough outer surface of the maxilla (upper jaw bone) and the pronounced crests around the eyes on the lacrimal, postorbital, and jugal bones. The orbit (eye socket) was a tall oval, somewhere in between the circular shape seen in Gorgosaurus and the 'keyhole' shape of Tyrannosaurus.
Deinocheirus mirificus
Deinocheirus is a genus of very large ornithomimosaurian dinosaur that lived in what is now southern Mongolia during the late Cretaceous period around 70 million years ago. The genus Deinocheirus contains one species, Deinocheirus mirificus. D. mirificus was long thought of as a very mysterious dinosaur, known only from a set of gigantic fossil arm bones. The discovery of more complete skeletons helped to solve this longstanding mystery, revealing a very strange, giant, bipedal omnivore. Deinocheirus mirificus was a large ornithomimosaurian, measuring up to 11 m (36 ft) long, and with an estimated upper weight of 6.358 t (6.258 long tons; 7.008 short tons). Though it had many of the typical skeletal features of its group, its overall appearance was very different from its relatives. While other ornithomimosaurians were light and fleet-footed, Deinocheirus had evolved to outsize its predators, and effectively became slower and bulkier.
