Dreadnoughtus is the biggest dinosaur ever found. Dr. Ken Lacovara (Rowan University) is the paleontologist who discovered it. He tells comedians Aparna Nancherla, Hari Kondabolu, and Maeve Higgins all about tiny headed dinos, breaking rocks, and how he once intimidated Harrison Ford. Recorded at the Franklin Institute as part of the 2016 Philadelphia Science Festival. Hosted by Chris Duffy. Produced by Pretty Good Friends.
