拉乌拉芒康龙是一种
恐龙,开始时被列为爬行类的一目,但现在根据其骨盘构造的不同,可区分为蜥臀目(saurischia)和鸟臀目(Ornithischia)两目。过去所说的禽龙是根据R·欧文(R.Owen1912年)命名的。从三叠纪到白垩纪非常繁盛,白垩纪末绝灭。
恐龙类dinosaurs简介
曾分布于6个大陆,适应各种环境,有肉食性的和草食性的。前肢比后肢短,多数只用后肢步行,但其中也有四肢步行的。侏罗纪以后出现了颈尾均长的巨大的类型(载域龙,Atloantosaurus体长30米以上,体重约50吨),牙齿深埋于齿槽内,并局限在颚骨的周缘。脊椎骨有双凹型、平凹型、后四型的区别,但其后代几乎都为后凹型。有的种类与鸟相近,骨中空,如霸王龙(Ty-rranosaurus),雷龙(Brontosaurus),禽龙(Ig-uanodon),剑龙(stegosaurus),钩龙(Ankylo-saurus),三角龙(Triceratops)等都是。在南库页岛产的日本龙(Nipponosaurus)是属于草食龙,是鸭嘴龙类之一种。日本长畸县高岛煤矿内有类似的小残片发现。
种类概要
许多的古生物学家相信恐龙形成单一的爬行动物族群,即恐龙类(Dinosauria)。它们与其它爬行动物最大区别在於它们的站立姿态与行进方式。恐龙具有全然直立的姿势,其四肢构建在其体躯的正下方位置。这样的架构要比那些其它种类的爬行动物,像是鳄类(其四肢向外侧伸展方式),在走路与奔跑上更有效益,更为方便。恐龙和其它灭绝的爬行动物能够明显的区分,主要是根据其腰带(骨盘构造)与四肢的骨骼学特徵,这些在演化上的发展,能够让恐龙得以站立奔走。
在传统上,恐龙被分类成两个族群:根据其髋骨(腰带)的构造,分为蜥臀类(像蜥蜴似的髋骨)与鸟臀类(像鸟类的髋骨)。最近,第三类的恐龙族群,慢龙类(Segnosaurischia)被提出,也是根据了腰带的构造而分类的。
在蜥臀类中,其腰带非常类似於现生的爬行动物,其髋骨系统中,耻骨伸前前方,而坐骨则伸向体躯的後方。在鸟臀类中,则具有较为复杂的腰带构造。其中髋骨系统中,耻骨已经转向体躯的後方,而与坐骨呈平行排列,与现生鸟类有些类似。同时鸟臀类在下颌骨也发展出了前齿骨。慢龙类(意即缓慢的,具蜥蜴腰带构造的,恐龙)则具有一种非常奇特的腰带构造,称之为後腰型(opisthopubic);其髂骨彼此相当的宽阔而分隔,其中前段非常深而长,而其尖端外外伸展成将近90度垂直位置。
慢龙类具有一个相当硕长的脖子,头颅相对的很小,而腰带特异,其耻骨与坐骨几近平行,甚而接合在一起。除了这个特殊的腰带构造而外,在其它骨骼构造上也有不同之处:颈椎与背椎都非常轻巧,而颈椎非常硕长其神经棘很短,小的头骨上,于上颌有纤细的牙齿排列。四肢具有四趾,每一趾都有长爪,均指向前方伸展。
