White Rhinoceros - Ceratotherium simum
The White Rhinoceros or Square-lipped rhinoceros (Ceratotherium simum) is one of the five species of rhinoceros that still exist. It has a wide mouth used for grazing and is the most social of all rhino species. The White Rhino consists of two subspecies: the Southern White Rhino, with an estimated 17,460 wild-living animals at the end of 2007 (IUCN 2008), and the much rarer Northern White Rhino. The northern species has very few remaining, all in captivity. The White Rhinoceros is the largest of the five species of rhinoceros and the world's largest land mammal after the three species of elephant. It has a massive body and large head, a short neck and broad chest. The head and body length is 3.7 to 4 m (12 to 13 ft) in males and 3.4 to 3.65 m (11 to 12.0 ft) in females, with the tail adding another 70 cm (28 in) and the shoulder height is 1.7 to 1.85 m (5 ft 7 in to 6 ft 0.8 in) in the male and 1.6 to 1.77 m (5 ft 3 in to 5 ft 10 in) in the female. Weight in this animal typically ranges from 1,360 to 3,630 kg (3,000 to 8,000 lb). The male, averaging 2,300 kg (5,100 lb) is slightly heavier than the female, at an average of 1,700 kg (3,700 lb). The largest recorded White Rhinoceros was about 4,500 kg (9,900 lb). On its snout it has two horn-like growths, one behind the other. These are made of solid keratin, in which they differ from the horns of bovids (cattle and their relatives), which are keratin with a bony core, and deer antlers, which are solid bone. The front horn is larger and averages 90 cm (35 in) in length, reaching as much as 150 cm (59 in). The White Rhinoceros also has a noticeable hump on the back of its neck. Each of the four stumpy feet has three toes. The color of the body ranges from yellowish brown to slate grey. Its only hair is the ear fringes and tail bristles. White Rhinos have a distinctive broad, straight mouth which is used for grazing. Its ears can move independently to pick up sounds but it depends most of all on smell. The olfactory passages which are responsible for smell are larger than their entire brain. The white rhinoceros has the widest set nostrils of any land based animal.
allosaurus fragilis
Allosaurus is a genus of carnivorous theropod dinosaur that lived 155 to 150 million years ago during the late Jurassic period (Kimmeridgian to early Tithonian). Allosaurus was a typical large theropod, having a massive skull on a short neck, a long tail and reduced forelimbs. Allosaurus fragilis, the best-known species, had an average length of 8.5 m (28 ft), with the largest definitive Allosaurus specimen (AMNH 680) estimated at 9.7 meters (32 feet) long, and an estimated weight of 2.3 metric tons (2.5 short tons). As with dinosaurs in general, weight estimates are debatable, and since 1980 have ranged between 1,500 kilograms (3,300 pounds), 1,000 to 4,000 kg (2,200 to 8,800 lb), and 1,010 kilograms (2,230 pounds) for modal adult weight (not maximum). Using the subadult specimen nicknamed "Big Al", researchers using computer modelling arrived at a best estimate of 1,500 kilograms (3,300 lb) for the individual, but by varying parameters they found a range from approximately 1,400 kilograms (3,100 lb) to approximately 2,000 kilograms (4,400 lb).
