Palaeoloxodon - Palaeoloxodon Namadicus
Palaeoloxodon namadicus or the Asian straight-tusked elephant, was a species of prehistoric elephant that ranged throughout Pleistocene Asia, from India to Japan. Some authorities regard it to be a subspecies of Palaeoloxodon antiquus, the European straight-tusked elephant, due to extreme similarities of the tusks. Several studies have attempted to estimate the size of the Asian straight-tusked elephants, as well as other prehistoric proboscideans, usually using comparisons of thigh bone length and knowledge of relative growth rates to estimate the size of incomplete skeletons. One partial skeleton found in India in 1905 had thigh bones that likely measured 165 centimetres (5.41 ft) when complete, suggesting a total shoulder height of 4.5 metres (14.8 ft) for this individual elephant. Two partial thigh bones were found in the 19th century and would have measured 160 cm (5.2 ft) when complete. A fragment from the same locality was said to be almost a quarter larger; volumetric analysis then yields a size estimate of 5.2 metres (17.1 ft) tall at the shoulder and 22 tonnes (24.3 short tons) in weight.
Shantungosaurus - Shantungosaurus Giganteus
Shantungosaurus is a genus of very large saurolophine hadrosaurid dinosaur found in the Late Cretaceous Wangshi Group of the Shandong Peninsula in China, containing a single species, Shantungosaurus giganteus. Shantungosaurus giganteus is one of the largest known ornithischians. The type skull is 1.63 metres (5.3 ft) long, and the composite skeleton mounted at the Geological Institute of China in Beijing measures 14.7 metres (48 ft) in length. Another mounted skeleton, originally referred to as Zhuchengosaurus maximus, measures 16.6 metres (54 ft) in length. The largest individuals may have weighed as much as 16 tonnes (18 short tons). Like all hadrosaurs its beak was toothless, but its jaws were packed with around 1,500 tiny chewing teeth. A large hole near its nostrils may have been covered by a loose flap of skin, which could be inflated to make sounds.
