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.
在中国,一组研究员最近发现新品种的恐龙,而且牠可能是现代鸟类与恐龙最古老的链接,古生物学家在中国辽宁发现1亿2500万年前的化石。这个古代生物长约三英尺,有羽毛覆盖,而且具有一嘴牙。

The new species has been named Jianianhualong tengi. Scientists
announced its discovery in a study published on May 2 in Nature
Communications.
这个新品种被命名为Jianianhualong
tengi。科学家在一篇于5月2号发表于《Nature
Communications》(国际排名第3的混合型期刊)的研究宣告其发现。

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,该科下都是与现代鸟类类似的恐龙。研究人员不确定Jianianhualong
tengi是否可以飞行。但是保存完整的化石遗迹指出它具有不对称的、或说其中一边比较长的羽毛。这是动物演化出飞行的关键。

“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关联的,但是某些不能飞的品种也具有不对称羽毛,而他们的外观是羽毛演化上的重要事件。」该研究的作者写道。

The Jacobin pigeons is one of approximately 350 breeds of domesticated
pigeon around the world. Most such breeds descend from the wild rock
pigeon (Columbia
livia)。雅各布鸽属全球家鸽大约350个品种中的一种。这种品种的鸽子大多起源于野鸽(其学名为Columbia
livia)。

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年发现Archaeopteryx,其为另一种似鸟恐龙,时首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.
但是根据新研究,Jianianhualong
tengi是最早具有不对称伤齿龙羽毛的,代表恐龙可能在原本所知的时间点前就具有类似鸟类的特征。

A male greater bird ofparadise (Paradisaea apoda) poses in the hope of
attracting a female in the Aru Islands of Indonesia. This courtship
display happens on treetop branches the birds havestripped of their
leaves, leaving a clear space in which to put on displays in the early
morning
light。在印度尼西亚的阿鲁群岛上,一只雄性大极乐鸟(学名为Paradisaea
apoda)正为吸引一只雌性大极乐鸟而大摆造型。鸟儿会将树梢上的枝叶去除,给它们的求爱舞留出空地。于是在清早的晨曦中,这场求爱秀就这么上演了。

“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.”
「羽毛的不对称对鸟类的飞行很重要是广受认同的。」徐星,共同参与这次的研究的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征在鸟类以外也广泛存在。」

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.
科学家将开始研究Jianianhualong tengi
以了解更多有关它如何使用他的羽毛并试图决定他是否能飞。这项调查对科学家对有羽毛的恐龙的想法造成具大的冲击。有些人相信无法飞行的有羽恐龙用羽毛来协助他们在地上移动。另一个潜在的用途可能是羽毛是用以增加对配偶的吸引力。

An adult male Wilson’s bird of paradise (Cicinnurus respublica) shows
off modified, wirelike tail feathers shaped like sickles. It’s because
of this distinctive feature that this species, along with two related
species, are called
“sickletails”。一只成年雄性威氏极乐鸟(学名为Cicinnurus
respublica)向我们炫耀了它弯若镰刀、犹如细丝的整洁尾羽。正是这种显著的特征,这种鸟类同与之相关的两种鸟类被称为“镰尾鸟”。

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.

“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.”
「我们期许有天某人或许会发现伤齿龙科不对称的羽毛,因为他们有着跟鸟类极为类似的骨骼。」研究的领导,来自香港大学的迈克皮特曼告诉富比士:「但这个某人是我们真的很棒。」
