00:00:37 Beneath the earth we know...

00:01:23 mostly farmland today.

00:04:14 As if from nowhere, the distant past returns.

00:05:28 Yeah, it looks like Hesperornis.

00:07:17 She gives birth to a male...

00:08:32 a bird that can't fly and has a beak full of sharp teeth.

00:10:17 and get a face full of ink.

00:11:28 in the Triassic period...

00:12:26 and unaware of the huge predators in the sea beyond.
