Grey Wolf (pack of 2) - Canis lupus
The Grey Wolf (Canis lupus) is the largest wild canid, males averaging between 70 and 110 pounds depending on subspecies. The Wolf has a specialized body that has made it one of the world's most efficient hunters. Its powerful neck is a very important adaptation: it has to be strong to support the wolf's large head and is crucial for bringing down prey. The skull is 31cm (12 inches) long and is armed with an impressive array of large canines and carnassial teeth which, when coupled with huge jaw muscles that are evident from the large sagittal crest and wide zygomatic arches, give it an incredible biteforce that is strong enough to break the bones of prey and even crack the femur of moose. Wolves primarily feed on medium to large sized ungulates (up to the size of bison 10–15 times larger than themselves), though they are not fussy eaters. Medium and small sized animals that may supplement the diet of wolves include marmots, beaver, hares, badgers, foxes, weasels, ground squirrels, mice, hamsters, voles and other rodents, as well as insectivores.
Deinonychus antirrhopus
Based on the few fully mature specimens, Deinonychus could reach 4 metres (13 ft) in length, with a a weight of 111 kg (244 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.
