The researchers also found that Shuvuuia had a very wide scleral ring -- tiny bones that circle the eyeball.

研究人员还发现鸟面龙有非常宽巩膜环——环绕眼球微小骨骼。

Most of it is that white stuff called the sclera, while the most anterior part is the transparent cornea.

大部分是被称为巩膜白色物质，而最前面部分是透明角膜。

In fact, research has shown that our surprisingly white scleras, the area that borders the iris, isn't just an accident.

I know icteric sclera, yellow eyes and yellow baby.

我知道黄疸巩膜，黄色眼睛和黄色婴儿。

In 2010, a group of researchers looked at a sample of eye bones, called scleral rings.

2010 年，组研究人员观察了眼骨样本，称为巩膜环。

Recycling of that heme group yields unconjugated bilirubin, which at high concentration can cause scleral icterus, jaundice, and bilirubin gall stones.

亚铁血红素循环利用会产生非结合胆红素，其浓度过高会导致巩膜黄染、黄疸与胆红素胆结石。

One interesting byproduct is that humans have relatively large white sclera and nearly black pupils and a dark iris.

有趣副产品是，人类拥有相对较大白色巩膜、近乎黑色瞳孔以及深色虹膜。

And along with the scleral rings, researchers have unearthed more fossil evidence that dinosaurs weren't entirely limited to daytime hours.

除了巩膜环，研究人员还发掘了更多化石证据，证明恐龙并不完全局限于白天。

The sclera covers everywhere except the very front of your eyeball, where it connects to the clear tissue that makes up your cornea.

巩膜覆盖除眼球最前面以外所有地方，与构成角膜透明组织相连。

It's so important that even dogs have evolved to have larger white sclera and more developed eyebrow muscles in order to show more of their sclera.

You don't see such prominent white sclera in any other primates, which means that the importance of nonverbal expressiveness and intent is especially important for human survival.

在其他灵长类动物中， 你看不到如此显著白色巩膜，这意非语言表达和意图重要性对于人类生存尤为关键。

Now, some dinosaurs also had scleral rings, and when they applied that same approach to 23 dinosaur fossils in 2011, the researchers found that plenty of them were most likely active at night—including hunters like Velociraptor.

现在，些恐龙也有巩膜环，当他们在 2011 年对 23 种恐龙化石采用同样方法时， 研究人员发现其中很多恐龙很可能在夜间活动——包括像迅猛龙这样猎手。
