STEVE BRUSATTE, a paleontologist on the faculty of the School of GeoSciences at the University of Edinburgh in Scotland, served as the expert reviewer for this atlas. He grew up in the midwestern United States and has a B.S. in Geophysical Sciences from the University of Chicago, M.Sc. in Paleobiology from the University of Bristol, and Ph.D. in Earth and Environmental Sciences from Columbia University in New York. He has written more than 150 peer-reviewed scientific papers during his 15 years of research in the field, named and described over a dozen new species of dinosaurs and mammals, and led groundbreaking studies on how dinosaurs rose to dominance and eventually went extinct, and were then replaced by mammals. Among his particular research interests are the evolutionary transition between dinosaurs and birds and the rise of placental mammals. He is also a noted specialist on the anatomy, genealogy, and evolution of the carnivorous dinosaurs like Tyrannosaurus and Velociraptor. His 2018 book, The Rise and Fall of the Dinosaurs, was a New York Times best seller, and he is the science consultant for the Jurassic World film franchise.
