How big is 暴龍?
7 米!
這隻恐龍已經滅絕了, 牠以前有 7 米長! 但暴龍是獵食者或腐食性動物還備受爭議. 雖然 暴龍很大, 但還不是最大的! 再拉遠一點看看最大的恐龍!
長頸鹿
長頸鹿是最大的陸地哺乳類, 令人難以置信的 6 米高! 光是牠的脖子大概就占了身高的一 半. 成年長頸鹿太高, 因此捕食者獵殺牠的唯一方式就是推倒牠!
巨大仙人掌
很可惜, 並不是每棵巨大仙人掌都會長到 14 米高, 有些可能只有五米高. 有些沒有手臂的 就稱作矛狀仙人掌.巨大仙人掌的手臂要花上 75 年才能長完全, 不過人類只要花不到 20 年.
大象
大象是最大的陸生動物, 但現在也僅存三種. 牠們可以重達八噸, 那大概是一般人體重的 100 倍!
阿波羅登月小艇
這個東西有 15 萬噸重! 好重! 它曾經登陸月球. 它啟發了電動玩具 "Lunar Lander", 那 個實在不簡單. 我每次玩都玩到沒燃料!
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.
