Hadrosaur (duckbilled dinosaur) ungual (toe claw) cast from Mid-Land Scientific Service of Canada. The original specimen was recovered from the Upper Cretaceous Judith River Formation of Red Deer RiverValley, Alberta, Canada.
Below, postcards showing out-dated interpretations of crested hadrosaurs — the first, of a life-sized statue or Corythosaurus at “Prehistoric Parks” in Drumheller, Alberta, Canada; the other, one of a series of prehistoric-animal postcards, this one showing Parasaurolophus.
