Lyrics

How can you tell? By looking at various features of the hip bones and hind limb bones, and also the arms, the arms in this animal are still very short. Whereas the animals walk on all fours, the forearms seem to get much longer and nearly the same length as the hind legs. Excellent. So this is a new species discovered at this quarry? That's right. And what kind of information does it give with regards to the evolution of these dinosaurs then? It tells us a lot more about how the locomotion in these animals evolved, how they walked. It tells us a bit more potentially about how they may have increased in body size because larger animals tend to walk on all fours. So it gives us a nice window on the evolution of this group and the origin of these gigantic Sauropods. So this is it, a new species of dinosaur discovered here in South Africa, it's been named Aardonyx Celestae. This species helps to fill in another gap in our understanding of how dinosaurs that walked on two legs eventually became the four-legged goliaths that are icons of the Jurassic.
你是怎么确定的? 通过观察股骨和后肢骨的各种特征,还有前肢骨,这只恐龙的前肢依旧短小,而其他四肢行走的恐龙前肢就变得更长一些,几乎与后肢等长。 真厉害,那么这是在这一区域发现的新物种喽? 没错 这对研究恐龙的进化提供了什么信息呢? 我们分析出进化过程中栖息地的变迁,以及动物行走方式的改变,也可以推断出恐龙的体型增大了。因为大型动物往往四肢着地行走,它为我们打开一扇奥妙之窗,揭示了大型蜥脚目恐龙的起源与进化过程,而这种于南非发现的新物种恐龙,被命名为地爪龙。它为我们填补了进化过程的一环,展示了两肢行走的恐龙,是如何演化成四肢行走的巨兽成为侏罗纪的标志。
