BBC Life On Earth Disc 2: Victors of the Dry Land (1979)

Reptiles developed a dry skin and a waterproof covering for their eggs. So equipped, they were able to colonise the driest lands. As they spread across the continents, so they evolved into a multitude of species. Dinosaurs dominated the world. Although they disappeared sixty-five million years ago, their relatives - snakes and lizards - still rule the hot deserts of the world.

Peter's DVD rating:
David Attenborough examines the reptiles. One minor error: he asserts that reptiles were the first creatures to develop real thirsts; making the common assumption that aquatic organisms don't have to drink, but in fact all marine fishes have to drink constantly in their hypertonic environment. Attenborough's explanation of the extinction of the dinosaurs is also dated; the Chicxulub impact crater that supports a meteorite cause of the extinction has not yet been discovered.

Peter's DVD rating: 4.5 stars
