Biography

Dr. Matt Lamanna is the Mary R. Dawson Curator of Vertebrate Paleontology and the principal dinosaur researcher at Carnegie Museum of Natural History in Pittsburgh. Originally from the Finger Lakes region of upstate New York, he received his B.Sc. from Hobart College in 1997 and his M.Sc. and Ph.D. from the University of Pennsylvania in 1999 and 2004. Within the past 26 years, he has directed or co-directed field expeditions to Antarctica, Argentina, Australia, China, Croatia, Egypt, Greenland, and the western United States that have resulted in the discovery of more than 20 new species of dinosaurs and other fossil animals from the Cretaceous Period, the third and final time period of the Age of Dinosaurs; indeed, he is one of only a handful of people to have found dinosaur fossils on all seven continents. Lamanna served as chief scientific advisor to Carnegie Museum of Natural History’s $36M Dinosaurs in Their Time exhibition and has appeared on television programs for PBS (NOVA), the Discovery Channel, the History Channel, A&E, the Science Channel, and more.
