Blaire van Valkenburgh
This week we explore the extraordinary and remarkable feats of super-strength herbivores as well as research into obesity.
Valkenburgh uncovers Pleistocene-era teeth and examines them to determine exactly how these giant predators survived.
Thousands of years ago, the only animals capable of hunting giant herbivores were equally gigantic carnivores. Get an up close and personal look at these crazy beasts!
