Dr. Kenneth Lacovara has unearthed some of the largest dinosaurs ever to walk our planet, including the super-massive Dreadnoughtus, which at 65 tons weighs more than seven T. rex. In his quest to understand these titanic creatures that strain the human imagination, Lacovara blends exploration in remote locations across the globe with the latest imaging and modeling techniques from engineering to medicine.
He joined us to talk about his TED book "Why Dinosaurs Matter."
