恐龙,动物之一,最成功的群体(在长寿方面)有过生活,成为许多不同的尺寸和形状的演变,与许多同样多样的生活模式。术语“恐龙”是1842年发明的描述这些“可怕的巨大爬行动物理查德欧文爵士,”特别是斑龙,禽龙,和林龙,仅有的三个当时已知恐龙。我们的生物,通常在为恐龙生活在中生代认为,从三叠纪晚期至白垩纪(约65万年前结束(大约2.25亿年前))。但我们现在知道,他们实际上今天的活鸟。 有些事情要记住对恐龙: ?并非一切都大,死是一种恐龙。很多时候,书上的通俗的(或电影制作)包括诸如猛犸,乳齿象,翼龙,蛇颈龙,鱼龙类动物,船帆支持的异齿龙。恐龙是一种特定的初龙小组,一组,还包括鳄鱼,翼龙类和鸟类。虽然翼龙的密切关系,他们不是真正的恐龙。更远亲恐龙的海洋爬行动物,其中包括蛇颈龙和鱼龙。猛犸和乳齿象是哺乳动物,并没有出现,直到数百万年后白垩纪结束。异齿龙既不是爬行动物,也不是哺乳动物,但基础synapsid,即早期的哺乳动物的祖先的亲戚。 ?并非所有的恐龙生活在同一时间。生活在不同时代不同的恐龙。尽管像金刚和侏罗纪公园,没有剑龙电影描绘见过一暴龙,因为暴龙没有在现场出现,直到80多万年后stegosaurs灭绝。也是一样迷惑龙(“雷龙”)?它的骨头早已由时间来一直暴龙化石。 ?恐龙没有灭绝。技术上。根据骨骼的功能,大多数人认为鸟类研究恐龙是恐龙。这起骇人听闻的实现使得即使是最小的一个合法的蜂鸟恐龙。因此,而不是指“恐龙”,是离散,最好是分批鸟称为“非禽类的恐龙”和鸟类的,那么,鸟,或“禽流恐龙的传统,已灭绝的动物。”这是不正确的说,恐龙的灭绝,因为他们离开住在鹦鹉,cassowaries形式的后裔,他们的好朋友?就像仍然脊椎动物尽管他们的祖先是长期寒武纪现代脊椎动物灭绝。 Dinosaurs, one of the most successful groups of animals (in terms of longevity) that have ever lived, evolved into many diverse sizes and shapes, with many equally diverse modes of living. The term "Dinosauria" was invented by Sir Richard Owen in 1842 to describe these "fearfully great reptiles," specifically Megalosaurus, Iguanodon, and Hylaeosaurus, the only three dinosaurs known at the time. The creatures that we normally think of as dinosaurs lived during the Mesozoic Era, from late in the Triassic period (about 225 million years ago) until the end of the Cretaceous (about 65 million years ago). But we now know that they actually live on today as the birds. Some things to keep in mind about dinosaurs: ? Not everything big and dead is a dinosaur. All too often, books written (or movies made) for a popular audience include animals such as mammoths, mastodons, pterosaurs, plesiosaurs, ichthyosaurs, and the sail-backed Dimetrodon. Dinosaurs are a specific subgroup of the archosaurs, a group that also includes crocodiles, pterosaurs, and birds. although pterosaurs are close relations, they are not true dinosaurs. Even more distantly related to dinosaurs are the marine reptiles, which include the plesiosaurs and ichthyosaurs. Mammoths and mastodons are mammals and did not appear until many millions of years after the close of the Cretaceous period. Dimetrodon is neither a reptile nor a mammal, but a basal synapsid, i.e., an early relative of the ancestors of mammals. ? Not all dinosaurs lived at the same time. Different dinosaurs lived at different times. Despite the portrayals in movies like King Kong and Jurassic Park, no Stegosaurus ever saw a Tyrannosaurus, because Tyrannosaurus didn't appear on the scene until 80 or so million years following the extinction of stegosaurs. The same goes for Apatosaurus ("Brontosaurus") ? it's bones were already well-fossilized by the time T. rex came along. ? Dinosaurs are not extinct. Technically. Based on features of the skeleton, most people studying dinosaurs consider birds to be dinosaurs. This shocking realization makes even the smallest hummingbird a legitimate dinosaur. So rather than refer to "dinosaurs" and birds as discrete, separate groups, it is best to refer to the traditional, extinct animals as "non-avian dinosaurs" and birds as, well, birds, or "avian dinosaurs." It is incorrect to say that dinosaurs are extinct, because they have left living descendants in the form of cockatoos, cassowaries, and their pals ? just like modern vertebrates are still vertebrates even though their Cambrian ancestors are long extinct.
