Hans-Dieter Sues is a German-born paleontologist who is Senior Scientist and Curator of Vertebrate Paleontology at the National Museum of Natural History of the Smithsonian Institution in Washington, DC. He received his education at Johannes Gutenberg-Universität Mainz (University of Mainz), University of Alberta, and Harvard University (Ph.D., 1984). Before assuming his present position, Sues worked at the Royal Ontario Museum and the University of Toronto and at the Carnegie Museum of Natural History in Pittsburgh. He is interested in the diversity, paleoecology, and evolutionary history of Mesozoic tetrapods, especially archosaurian reptiles and cynodont therapsids, and the history of biology and paleontology. Sues has discovered a number of new dinosaurs and other extinct terrestrial vertebrates in Mesozoic continental strata around the world. He has authored or co-authored over 100 articles and book chapters on vertebrate paleontology and paleoecology. Sues has edited Evolution of Herbivory in Terrestrial Vertebrates (Cambridge Univ. Press, 2000) and co-edited Terrestrial Ecosystems through Time (with A. K. Behrensmeyer et al.; Univ. of Chicago Press, 1992), In the Shadow of the Dinosaurs: Early Mesozoic Tetrapods (with N. C. Fraser; Cambridge Univ. Press, 1994), and Major Transitions in Vertebrate Evolution (with J. S. Anderson; Indiana Univ. Press, 2007). He is also active in promoting the value of natural history collections for addressing major questions in current science. Sues was elected a Fellow of the Royal Society of Canada in 2003 and a Fellow of the American Association for the Advancement of Science in 1998. The pachycephalosaur Hanssuesia is named for him.
