Dale Russell
Dale Alan Russell was an American-Canadian geologist and palaeontologist. He was Research Professor at the Department of Marine Earth and Atmospheric Sciences at North Carolina State University and Senior Paleontologist at the North Carolina Museum of Natural Sciences. Dinosaurs he has described include Daspletosaurus and Dromiceiomimus, and he was amongst the first paleontologists to consider an extraterrestrial cause for the Cretaceous–Paleogene extinction event.
In 1982, Russell created the "dinosauroid" thought experiment, which speculated an evolutionary path for Troodon if it had not gone extinct in the Cretaceous–Paleogene extinction event 66 million years ago, and had instead evolved into an intelligent being. Russell commissioned a model of his dinosauroid by artist Ron Sequin, and the concept became popular. Various later anthropologists have continued Russell's speculations about intelligent Troodon-like dinosaurs, though they often find his original idea too anthropomorphic.
