Dale Russell

Dale A. Russell (April 2, 1947) is a Canadian geologist/palaeontologist, currently Research Professor at The Department of Marine Earth and Atmospheric Sciences (MEAS) of North Carolina State University. Dinosaurs he has described include Daspletosaurus and he was the first paleontologist to suggest an extraterrestrial cause (supernova, comet, asteroid) for the extinction of the dinosaurs. He is also credited with inventing the controversial dinosauroid thought experiment. Russell's dinosauroid was criticized as being too antropomorphic.
