史前系列：极地寻龙 (下) Ancient Earth: Dinosaurs of the Frozen Continent
第二集，勘探行动持续推进。我们将揭晓：1990年代「南极暴龙」冰冠龙（Cryolophosaurus）与长达7米的草食性动物——冰川龙（Glacialisaurus）的重大发现，如何让这片曾被视为生命荒漠的冰原大陆，重新点燃世人的探索热情；并呈现新证据，指出坚韧的原始哺乳动物水龙兽（Lystrosaurus）可能透过休眠熬过极地黑暗寒冬与剧毒气候剧变；最终揭示六千六百万年前，小行星撞击地球后，南极恐龙与史前生物的真正命运归宿。
In the second of two episodes, the expedition continues apace. We find out how the great discovery in the 1990s of the Cryolophosaurus, dubbed the T-Rex of Antarctica, and a 25-foot-long plant eater, the Glacialisaurus, lead to a renewed interest in a continent that was once thought to be largely devoid of life. And reveal how new evidence that a tough proto-mammal, Lystrosaurus, may have hibernated to survive dark polar winters and toxic climate upheaval; and, ultimately, reveal what happened to the Antarctic dinosaurs and prehistoric creatures after the infamous asteroid struck the earth 66 million years ago.
