How big is 暴龙?
7 米!
这只恐龙已经灭绝了, 牠以前有 7 米长! 但暴龙是猎食者或腐食性动物还备受争议. 虽然 暴龙很大, 但还不是最大的! 再拉远一点看看最大的恐龙!
长颈鹿
长颈鹿是最大的陆地哺乳类, 令人难以置信的 6 米高! 光是牠的脖子大概就占了身高的一 半. 成年长颈鹿太高, 因此捕食者猎杀牠的唯一方式就是推倒牠!
巨大仙人掌
很可惜, 并不是每棵巨大仙人掌都会长到 14 米高, 有些可能只有五米高. 有些没有手臂的 就称作矛状仙人掌.巨大仙人掌的手臂要花上 75 年才能长完全, 不过人类只要花不到 20 年.
大象
大象是最大的陆生动物, 但现在也仅存叁种. 牠们可以重达八吨, 那大概是一般人体重的 100 倍!
阿波罗登月小艇
这个东西有 15 万吨重! 好重! 它曾经登陆月球. 它启发了电动玩具 "Lunar Lander", 那 个实在不简单. 我每次玩都玩到没燃料!
Maip
A genus of large theropod dinosaur from the Late Cretaceous (approximately 70 million years ago) discovered in modern-day Patagonia. Named Maip macrothorax, it was a member of the megaraptorid family and measured around 33 feet (10 meters) long, and 11.4 feet (3.5 meters) wide. Maip was a fast predator, with large claws on its hands, slender legs, and a probable covering of protofeathers.
Tyrannosaurus
One of the most famous and fearsome dinosaurs, T. rex lived during the Late Cretaceous (around 68–66 million years ago). As an apex predator, it measured up to 40 feet (12 meters) in length, stood about 13–15 feet (4–5 meters) tall at the hips, and weighed between 9–14 tons. It had powerful jaws lined with teeth capable of crushing bone, a robust skull, and tiny but functional arms. Its diet included large prey like hadrosaurs and ceratopsians.
