Thomas R Holtz

PeerJ Author & Reviewer

Summary

Thomas R. Holtz, Jr. is Principal Lecturer in Vertebrate Paleontology at the Department of Geology, University of Maryland, College Park. His research focuses on the origin, evolution, adaptations, and behavior of carnivorous dinosaurs, and especially of tyrannosauroids (Tyrannosaurus rex and its kin). He received his Bachelors in Earth & Planetary Geology at Johns Hopkins in 1987 and his Ph.D. from the Department of Geology & Geophysics at Yale in 1992. He is also a Research Associate of the Department of Paleobiology of the Smithsonian Institution National Museum of Natural History and serves on the Scientific Council of Maryland Academy of Science (which operates the Maryland Science Center (Baltimore, MD)).

In addition to his dinosaur research, Holtz has been active in scientific outreach. He has been a consultant on museum exhibits around the world, and on numerous documentaries. He is the author of the award-winning Dinosaurs: The Most Complete, Up-To-Date Encyclopedia for Dinosaur Lovers of All Ages (Random House). He was co-editor of the 2014 2nd Edition of The Complete Dinosaur (Indiana Univ. Press) and is in the midst of co-editing the 3rd Edition.

He received the 2018-2019 Provost’s Excellence in Teaching Award for Professional Track Faculty.
