Professor David Bruce Weishampel (born November 16, 1952) is an American palaeontologist in the Center for Functional Anatomy and Evolution at Johns Hopkins University School of Medicine. Weishampel received his Ph.D. in Geology from the University of Pennsylvania in 1981. His research focuses include dinosaur systematics, European dinosaurs of the Late Cretaceous, jaw mechanics and herbivory, cladistics and heterochrony and the history of evolutionary biology. Weishampel's best known published work is The Dinosauria University of California Press; 2nd edition (December 1, 2004). He consulted for Jurassic Park and is a good friend of Steven Spielberg. He has received an Academy Scientific and Technical Award.
