在中华意识新类型的恐龙

By admin in 必赢网址是多少 on 2019年1月14日

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.
在华夏,一组探究员目前发觉新品类的恐龙,而且牠可能是当代鸟类与恐龙最古老的链接,古生物学家在炎黄河北发现1亿2500万年前的化石。这么些后梁生物长约三英尺,有羽毛覆盖,而且拥有一嘴牙。

The new species has been named Jianianhualong tengi. Scientists
announced its discovery in a study published on May 2 in Nature
Communications.
以此新品类被命名为Jianianhualong
tengi。数学家在一篇于十月2号发布于《Nature
Communications》(国际名次第3的混合型期刊)的钻研发布其发现。

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是一种伤齿龙科,该科下都是与当代鸟类类似的恐龙。研讨人士不确定Jianianhualong
tengi是否可以飞行。可是保存完好的化石遗迹提议它抱有不对称的、或说里面一头相比较长的羽绒。那是动物衍变出飞行的根本。

“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.
「不对称羽毛跟飞行能力是有提到的,不过某些不可能飞的连串也具备不对称羽毛,而她们的外观是羽毛衍变上的要紧事件。」该探究的撰稿人写道。

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年意识Archaeopteryx,其为另一种似鸟恐龙,时第一次发现恐龙具有羽毛

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.
然而按照新探讨,Jianianhualong
tengi是最早有所不对称伤齿龙羽毛的,代表恐龙可能在原本所知的时刻点前就具备类似鸟类的性状。

“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.”
「羽毛的非正常称对小鸟的航空很关键是广受认可的。」徐星,共同参加这一次的钻研的中国科高校古生物学家,告诉国家地理:「现在我们得以指出那个特性在小鸟以外也普遍存在。」

必赢网址是多少,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.
地理学家将上马切磋Jianianhualong tengi
以询问更多关于它什么采用他的羽绒并意欲操纵她是不是能飞。这项调查对数学家对有羽毛的恐龙的想法造成具大的相撞。有些人依赖不能飞行的有羽恐龙用羽毛来帮衬他们在地上移动。另一个暧昧的用途可能是羽毛是用于增添对配偶的重力。

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.

和其不对称的羽毛将帮扶解答这一个问题,甚至能是出现的观点。它的觉察是紧要的突破,且使发现它的集体的探讨员异常鼓劲。

“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.”
「大家期许有天某人唯恐会发觉伤齿龙科不对称的羽绒,因为他们所有跟鸟类极为类似的骨骼。」研讨的集团主,来自香江大学的Mike皮特曼告诉富比士:「但以此某人是大家真的很棒。」
