Alaskan Moose - Alces alces gigas
The Alaska moose (Alces alces gigas) or giant moose or Alaskan moose is a subspecies of moose that ranges from Alaska to western Yukon. The Alaska moose is the largest North American subspecies of moose. Alaska moose inhabit boreal forests and mixed deciduous forests throughout most of Alaska and most of Western Yukon. Like all moose species, the Alaska moose is usually solitary but sometimes will form small herds. Typically, they only come into contact with other moose for mating or competition for mates. During mating season, in autumn and winter, male Alaska moose become very aggressive and prone to attacking when startled. Male Alaska moose can stand over 2.1 m (6.9 ft) at the shoulder, and weigh over 634.5 kg (1,399 lb). The antlers on average have a span of 1.8 m (5.9 ft). Female Alaska moose stand on average 1.8 m (5.9 ft) at the shoulder and can weigh close to 478 kg (1,054 lb). The largest Alaska moose was shot in western Yukon in September 1897; it weighed 820 kg (1,808 lb), and was 2.33 m (7.6 ft) tall at the shoulder. Alaska moose with the Chukotka moose, matches the extinct Irish elk as the largest deer of all time.
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.
