Graveyard of the Giant Beasts

Which giant animal was the apex predator 58 million years ago?

Sixty-five million years ago, a giant meteor hit the earth causing a global catastrophe that destroyed an estimated three quarters of the plants and animal species on the planet, including the mighty dinosaurs. Little was known about the survivors who lived in this post-apocalyptic world until a mining operation in Cerrejon, Northern Colombia —  excavating coal cut from deep within the earth’s crust — exposed an important layer in the earth’s geological history laid down more than 10 million years after the extinction of the dinosaurs.

Giant crocodiles and enormous snakes, living side by side. Scientific analysis will help put together a picture of this hostile prehistoric world to discover the strongest predator in this land filled with giants.

Secrets of the Dead: Graveyard of the Giant Beasts premieres Wednesday, November 2 at 10 p.m. on PBS (check local listings).
