Eusthenopteron, originally found in Quebec in the 1880s.

，最初 于 1880 年代在魁北克发现。

Well, we know that all three of our friends -- Eusthenopteron, Tiktaalik and Ichthyostega -- had gills.

好吧，我们知道我们的三个朋友——真翅目、提塔利克鱼和鱼石藻——都有鳃。

In Eusthenopteron, the spiracular tract opens up near the front of the skull, just like in most water-breathing fish with gills.

在 Eusthenopteron 中， 气孔在头骨前部附近打开，就像大多数带鳃的水肺鱼一样。

Even though its legs and hips were bigger than in Eusthenopteron, they weren't strong enough to bear the strain of walking on land.

尽管它的腿和臀部比东翼龙的大，但它们的力量不足以承受在陆地上行走的压力。

And for a long time, one of the few fossils that experts had to work with was a fish named Eusthenopteron, originally found in Quebec in the 1880s.

很长一段时间以来， 专家们必须研究的少数化石之一是一种名为 Eusthenopteron 的鱼，它最初于 1880 年代在魁北克发现。

So Eusthenopteron was maybe breathing air in addition to water, and since the hole was close to the front of the face, they probably used their gills to handle both.

所以 Eusthenopteron 可能除了水之外还在呼吸空气，而且由于洞靠近脸的前面，他们可能用鳃来处理这两者。

These hardy limbs could have helped Eusthenopteron move itself along in the shallows as it hunted other fish, but its fins probably weren't strong enough to let it walk on land.

这些强壮的四肢本可以帮助 Eusthenopteron 在捕食其他鱼类时在浅滩中移动，但它的鳍可能不够强壮， 无法让它在陆地上行走。
