我需要一篇有關暴龍的資料

請給我一些有關暴龍(T-rex)的資料!

而且是英文的! 不要太難 大概是小學四年級的程度

如果可以的話 請幫我整理成一篇演講稿 時間大概兩分鐘就可以了

要精簡一點喔

    暴龍(學名:Tyrannosaurus)又名霸王龍,模式種與目前唯一的有效種是雷克斯暴龍(Tyrannosaurus rex),或稱雷克斯龍,是一種大型的肉食性恐龍,身長約13公尺,臀部高度約4公尺,體重約6.8公噸。暴龍生存於白堊紀末期的馬斯垂克階最後300萬年,距今約6850萬年到6550萬年,是白堊紀-第三紀滅絕事件前最後的恐龍種群之一。化石分佈於北美洲的美國與加拿大西部,分佈範圍較其他暴龍科更廣。 暴龍的屬名在古希臘文中意為「暴君蜥蜴」,種小名在拉丁文中意為國王。有些科學家認為亞洲的勇士特暴龍(Tarbosaurus bataar)是暴龍屬的第二個有效種,而其他科學家則認為特暴龍是獨立的屬。除此之外,過去有許多暴龍科的種被歸類於暴龍屬,但目前多被認為是暴龍的異名,或被分類於其他屬。如同其他的暴龍科恐龍,暴龍是二足、肉食性恐龍,擁有大型頭顱骨,並藉由長而重的尾巴來保持平衡。相對於牠們大而強壯的後肢,暴龍的前肢非常小。長久以來,暴龍被認為只有兩根手指,但在2007年發現的一個完整的暴龍化石,顯示牠們可能具有三根手指。暴龍可能是種頂級掠食動物,以鴨嘴龍類與角龍下目恐龍為食,但有科學家認為暴龍是種食腐動物。雖然目前有其他獸腳亞目恐龍的體型與暴龍相當,或大於暴龍,暴龍仍是最大型的暴龍科動物,也是最著名的陸地掠食動物之一。目前已有超過30個雷克斯暴龍的標本被確認,包含數具完整度很高的化石。暴龍的大量化石材料,使科學家們有足夠的資料研究暴龍生理的各個層面,包括生長模式與生物力學。有些研究人員還在標本上發現了軟組織與蛋白質。但暴龍的食性、生理機能以及移動速度仍在爭論中。

    Tyrannosaurus (pronounced /tɨˌrænɵˈsɔrəs/ or /taɪˌrænɵˈsɔrəs/, meaning 'tyrant lizard') from the Greekwords τυράννος (tyrannos, meaning "tyrant") and σαύρος' (sauros, meaning "lizard"), is a genusof theropoddinosaur. The speciesTyrannosaurus rex ('rex' meaning 'king' in Latin), commonly abbreviated to T. rex, is a fixture in popular culture. It lived throughout what is now western North America, with a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formationsdating to the last two million years of the CretaceousPeriod, 67 to 65.5 million years ago.It was among the last non-aviandinosaurs to exist prior to the Cretaceous–Tertiary extinction event.Like other tyrannosaurids, Tyrannosaurus was a bipedalcarnivorewith a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small, though unusually powerful for their size, and bore two clawed digits. Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it was the largest known tyrannosaurid and one of the largest known land predators, measuring up to 12.8 m (42 ft) in length,up to 4 metres (13 ft) tall at the hips,and up to 6.8 metric tons (7.5 short tons) in weight.

    By far the largest carnivore in its environment, Tyrannosaurus rex may have been an apex predator, preying upon hadrosaurs and ceratopsians, although some experts have suggested it was primarily a scavenger.

    2010-09-22 22:38:22 補充:

    The debate over Tyrannosaurus as apex predator or scavenger is among the longest running debates in paleontology.More than 30 specimens of Tyrannosaurus rex have been identified, some of which are nearly complete skeletons.

    2010-09-22 22:38:48 補充:

    Soft tissue and proteins have been reported in at least one of these specimens. The abundance of fossil material has allowed significant research into many aspects of its biology, including life history and biomechanics.

    2010-09-22 22:40:02 補充:

    The feeding habits, physiology and potential speed of Tyrannosaurus rex are a few subjects of debate.

    2010-09-22 22:40:39 補充:

    Its taxonomy is also controversial, with some scientists considering Tarbosaurus bataar from Asia to represent a second species of Tyrannosaurus and others maintaining Tarbosaurus as a separate genus.

    2010-09-22 22:41:20 補充:

    Several other genera of North American tyrannosaurids have also been synonymized with Tyrannosaurus.

    因為字數超過,所以補充到意見,上面的英文把它接到我回打的英文後面
