tyrannosaursCOCA¹²⁷⁴⁰⁰BNC²³⁶²¹³⁺¹ 基本例句 n.暴龙类恐龙,霸王龙原型tyrannosaur的三单 But in the past year half a dozen new tyrannosaur species have been described, and during the past decade the known diversity of tyrannosaurs has more than doubled. 过去的一年里,发现了六个新霸王龙物种。而在过去的十年里所知道的霸王龙种类是之前的两倍多。 yeeyan Even as study of other tyrannosaurs proceeds at paleontologically breakneck pace, much is being learned about T. rex and its Asian counterpart, Tarbosaurs. 在对其他暴龙的研究取得了飞速进展的同时,古生物学家们对雷克斯暴龙和亚洲特暴龙的认识也上了一个新台阶。 yeeyan “These things didn't all form a smooth, gradual transition from small, older tyrannosaurs to big, more recent tyrannosaurs, ” said Brusatte. “从小型古暴龙向大型晚期暴龙的进化并不是一个平滑渐变的转变过程,”布鲁塞特说。 yeeyan Juvenile tyrannosaurs looked and behaved differently than adults did, so it's no wonder that paleontologists at first thought they belonged to an entirely new species. 幼年暴龙在外观和行为上都有别于成年暴龙,所以也难怪古生物学家当初会认为他们属于一个全新的物种了。 yeeyan Researchers now believe that tyrannosaurs spent almost all of their time on Earth as small, flighty predators like Raptorex. 研究人员现在认为,霸王龙在地球上进化过程中几乎多大多数时间就像 Raptorex一样,是一种体型小而轻快的食肉动物。 yeeyan Researchers studying tyrannosaurs have had a leg up over those working on other dinosaurs—and even some extant animals—given T. rex's wide popularity. 研究霸王龙的科研人员在研究其他种类的恐龙,甚至是在研究一些现存的动物上很占优势,这也就使得霸王龙广受欢迎。 yeeyan The finding has stunned palaeontologists because the skeleton resembles the larger tyrannosaurs in every respect except its size. 这一发现震惊了全世界的古生物学家,因为除了体型之外,它的骨架与霸王龙在任何方面都极为相似。 yeeyan The thinking has been that as tyrannosaurs developed to a truly giant size, they needed to modify their entire skeleton so they could function as predators. 之前的想法一直是,在霸王龙形成庞大体型的进化过程中,它们需要调整全身骨骼的大小,以便能够适应食肉动物的行动。 yeeyan Tyrannosaurs were the largest land- living meat eating animals that ever lived. 霸王龙是陆地上生存过的最大的肉食动物。8875 |
