"Troodon"s size ranged widely. In general, individuals that lived further north were larger than those that lived in more southern areas. "Troodons" in Alaska were especially large, up to 12 feet long, 5 feet tall, and weighing up to 175 pounds. Meanwhile, "Troodons" that lived in more southern locations were only around 7 feet long, 3 feet tall, and weighed up to 50 pounds, about the size of a "Velociraptor". Very likely "Troodon" had feathers, but no fossil evidence for feathers has yet been found.
