每当华夏发现新类型的恐龙!

A team of researchers in China recently found a new species of dinosaur,
and it might be the oldest link between dinosaurs and modern birds. The
paleontologists discovered the 125-million-year-old fossil in Lionaning,
China. The ancient animal was three-feet long, covered in feathers, and
sported a mouthful of teeth.
以炎黄,一组研究员最近发现新路的恐龙,而且牠可能是当代鸟类和恐龙最古老的链接,古生物学家在中华辽宁意识1亿2500万年前之化石。这个古代生物长约三英尺,有羽毛覆盖,而且富有同样嘴巴牙。

The new species has been named Jianianhualong tengi. Scientists
announced its discovery in a study published on May 2 in Nature
Communications.
斯新类型为命名为Jianianhualong
tengi。科学家于一如既往篇让5月2如泣如诉发表于《Nature
Communications》(国际排名第3之混合型期刊)的钻研揭示其发现。

Jianianhualong tengi is a type of troodontid, which is a family of
bird-like dinosaurs related to the modern-day birds. Researchers are
unsure if Jianianhualong tengi could fly. But the well-preserved
fossilized remains indicate that it had feathers that were not
symmetrical, or longer on one side than the other. This is a key element
in the evolution of animal flight.
Jianianhualong
tengi是一致栽伤齿龙科,该科下都是暨现代鸟类类似的恐龙。研究人口不确定Jianianhualong
tengi是否可飞行。但是保存完整的化石遗迹指出其有着不对称之、或说里面一头比较丰富的毛。这是动物演化出飞行之基本点。

“Asymmetrical feathers have been associated with flight capability, but
are also found in species that do not fly, and their appearance was a
major event in feather evolution,” the authors write in the study.
「不对称羽毛以及飞能力是生提到的,但是某些不克飞的门类为持有不对称羽毛,而她们之外观是毛演化上的要害事件。」该钻之撰稿人写道。

Paleontologists first discovered that dinosaurs sported feathers with
the 1861 discovery of the Archaeopteryx, a different type of bird-like
dinosaur.
古生物学家在1861年发觉Archaeopteryx,其也其他一样种似鸟恐龙,时首不行发现恐龙具有羽毛

But according to the new study, the Jianianhualong tengi “has the
earliest known asymmetrical troodontid feathers,” suggesting that
dinosaurs may have exhibited bird-like traits earlier than previously
believed.
不过依据新钻,Jianianhualong
tengi是极端早有不对称伤齿龙羽毛的,代表恐龙可能以原先所掌握的年华点前就颇具类似鸟类的特色。

“It is widely accepted that feather asymmetry is important for the
origin of bird flight,” Xu Xing, a paleontologist at the Chinese Academy
of Sciences who co-led this study, told National Geographic. “And now we
can demonstrate that this feature has a wide distribution outside the
bird family.”
「羽毛的非正常称针对鸟的宇航很重大是广受认同的。」徐星,共同参与这次的钻之中国科学院古生物学家,告诉国家地理:「现在我们可以指出这个特性于小鸟以外也普遍存在。」

Scientists will now study Jianianhualong tengi to learn more about how
it used its feathers and try to determine if it could fly or not. That
investigation could have a major impact on how scientists think about
feathered dinosaurs. Some believe that feathered dinosaurs that could
not fly used their plumage to help them get around on the ground.
Another potential use could have been to make them more attractive to
potential mates.
科学家将起来研究Jianianhualong tengi
以询问再多关于她怎么行使外的毛并准备操纵他是不是会飞。这项调研对科学家对来羽毛的恐龙的想法造成具特别的相撞。有些人深信不疑无法飞行之有羽恐龙用羽毛来助他们于地上走。另一个秘密的用或是毛是用以增加对配偶的吸引力。

Jianianhualong tengi and its asymmetrical feathers will help answer
those questions and likely pose new ones. Its discovery is a major
breakthrough, and it has researchers excited—especially the team that
found it.
Jianianhualong tengi
和其未对称的羽毛将协助解答这些题目,甚至能是出新的见。它的觉察是关键的突破,且一旦发现其的组织的研究员十分鼓劲。

“We expected that somebody might find asymmetrical feathers in a
troodontid someday because they have such similar skeletons to birds,”
study leader Michael Pittman from the University of Hong Kong told
Forbes. “But for it to be us was really wonderful.”
「我们期许有天有人想必会意识伤齿龙科不对称的羽毛,因为他们有与鸟类极为类似之骨骼。」研究之领导人员,来自香港大学的迈克皮特曼告诉富比士:「但以此某人是咱确实特别棒。」
