Brachiosaurus very obvious characteristics of the ordinary dinosaur foreleg mostly short, the type of dinosaur Brachiosaurus foreleg on longer; particularly their long neck. Overall appearance gives a sense of asymmetry; arm as long as not commensurate with the proportion of the body.
No sooner had more than the long neck surprising is the size of the body when the Brachiosaurus Gengzi elevation can be said to be foot-long dinosaur in the largest category.
Brachiosaurus is great, in fact than it is to have a huge dinosaur fossil, which is super-long, who is about 25 to 30 meters. Long compared to the super-huge, and that is serious Lung, 30 meters or more in length and weighing more than 130 tons. Both the dragon was that the family is like Brachiosaurus Unfortunately, the only body part found bones, otherwise may not Brachiosaurus history of the largest land animal has.
As Brachiosaurus body of too stupid, we all think that the past it was difficult living on the land.
Sequelae may be too heavy weight Zhenbushao, for instance, in the wet muddy ground, may not take steps on the sink; fall Once off guard, not Shuaipocaiguai stomach. So people held that Brachiosaurus usually live in the water, the buoyancy of water on the weight and only show his head in the water breathing. This kind of thinking and Brachiosaurus in the nostrils long coincides precisely on the head.
However, according to experts and scholars on the Brachiosaurus bones detailed survey has found that, Brachiosaurus physique, it is very suitable for living in the dry land. Also found that if Brachiosaurus live in the water, the lungs will be broken hydraulic pressure, Brachiosaurus will be unable to breathe and death.
腕龍類的特徵極為明顯,普通恐龍的前腳大多較短,腕龍類的恐龍前腳就較長;牠們的頸部尤其長。整體外型給人有不對稱之感;就像手臂特別長,如身體的比例不相稱。
比前腳及頸長更令人驚奇的是身體的大小;當腕龍把頸子抬高,可說是龍腳類恐龍中最大的。
腕龍雖然巨大,事實上曾出現比牠還要巨大的恐龍化石,那就是超級龍,身長約二十五~三十公尺。而比超龍還要巨大的,就是特大龍,身長三十公尺以上,體重超過一百三十噸。這兩種龍被認為是腕龍的族類,可惜只發現身體的部分骨頭,要不然腕龍可就不是歷史上陸地的最大動物了。
由於腕龍的身體太過於笨量,因此以往大家都認為牠很難在陸地上生活。
體重太重的後遺症可真不少,比如說,在泥濘的濕地上,可能沒走幾步就沈下去了;一不小心摔倒,肚子不摔破才怪。所以人們才認為,腕龍通常是生活在水中,靠水的浮力減輕體重,只露出頭部在水面呼吸。這種想法和腕龍的鼻孔長在頭頂上正好相吻合。
但是,根據專家學者對腕龍骨頭的詳細調查,卻明白發現,腕龍的體型,實在非常適合生活在乾燥的陸地上。同時也發現,如果腕龍生活在水中,肺部將被水壓壓破,腕龍將因無法呼吸而死亡。
