ngandong tiger
The Ngandong tiger (Panthera tigris soloensis) is an extinct subspecies of tiger which lived in what is now the Sundaland region of Indonesia during the Pleistocene epoch.
Fossils of P. t. soloensis have been found primarily in the village of Ngandong, hence the common name. Only seven fossils are known, making study of the animal difficult.
Most likely “Ngandong tiger’’ (also known as Pleistocene tiger) is not a separate species, but rather the “early version” of the same tigers we see today.
The reason for its large size was most likely due to the presence of larger competitors like the giant hyena and also as food supply was greater, and so the tigers themselves were bigger.
The tiger was as long as the American lion measuring up to 8.5 feet without tail and 13.5 feet with the tail but was much heavier. It could have measured in excess of 4 feet at the shoulder.
Some fragmentary remains (including massive jaws and fangs) have been found in Russia, China and Java, suggesting that these “Cave tigers” could reach up to 490 Kgs (1080lbs) in weight, being worthy contenders for the title of largest cat ever.
Grizzly Bear - Ursus arctos horribilis
The grizzly bear (Ursus arctos horribilis), also known as the silvertip bear, the grizzly, or the North American brown bear, is a subspecies of brown bear (Ursus arctos) that generally lives in the uplands of western North America. This subspecies is thought to descend from Ussuri brown bears which crossed to Alaska from eastern Russia 100,000 years ago, though they did not move south until 13,000 years ago. Except for cubs and females, grizzlies are normally solitary, active animals, but in coastal areas, the grizzly congregates alongside streams, lakes, rivers, and ponds during the salmon spawn. Every other year, females (sows) produce one to four young (commonly two) which are small and weigh only about 500 grams (1 lb). A sow is protective of her offspring and will attack if she thinks she or her cubs are threatened. The word "grizzly" in its name refers to "grizzled" or grey hairs in its fur, but when naturalist George Ord formally named the bear in 1815, he misunderstood the word as "grisly", to produce its biological Latin specific or subspecific name "horribilis". Most adult female grizzlies weigh 130–200 kilograms (290–440 lb), while adult males weigh 180–360 kilograms (400–790 lb), averaging 134 kg (295 lb) and 220 kg (485 lb), respectfully. The average total length in this subspecies is 198 centimetres (6.50 ft), with an average shoulder height of 102 centimetres (3.35 ft) d hindfoot length of 28 centimetres (11 in). Newborn bears may weigh less than 500 grams (1 lb). In the Yukon River area, mature female grizzlies can weigh as little as 100 kilograms (220 lb). On the other hand, an occasional huge male grizzly has been recorded which greatly exceeds ordinary size, with weights reported up to 680 kilograms (1,500 lb). Although variable from blond to nearly black, grizzly bear fur is typically brown in color with white tips. A pronounced hump appears on their shoulders; the hump is a good way to distinguish a black bear from a grizzly bear, as black bears do not have this hump.
