GermaDn ing in the shallow water and muddy bot- toms of streams and ponds. It is also shown by webbing between the toes, revealed in several cases where skin impressions of these animals have been preserved. The central type is Hadrosaunis (had-ro- sawr-us) or Trachodon (TRAK-o-don), found in various parts of western North America and in the eastern portion of the continent, too. Indeed, as already mentioned the first dinosaur skeleton to be found and described in North America was a Hadrosaunis skele- ton, discovered not in the wilds of the west- ern badlands, but in the town of Haddon- field, New Jersey, a suburb of Philadelphia. A glance will show that Trachodon was a camptosanr grown large, in which the skull was flattened, especially in front, to form the broad "duck bill" so characteristic of these dinosaurs. In late Cretaceous times there were nu- merous evolutionary variants of this central hadrosaurian theme, developments charac- terized for the most part by peculiar and bizarre modifications of the skull. One of these was Kritosaurus (kritt-o-SAWR-us). An- other was Corythosaurus (kor-ith-o-SAWR- us). Another was Lambeosaurus (lamb-e-o- sawr-us). Another was Parasaurolophus (par-a-sawr-AH-lof-us). Suffice it at this point to note the strange and wonderful lengths to which evolution carried these fascinating dinosaurs. On page 87 we refer further to the significance of the peculiar skull structure of the several types of hadrosaurian dinosaurs. A very peculiar group of ornithopod di- nosaurs was that of the troodonts (tro-o- dahnts), small to medium-size dinosaurs, in which the body seemingly was rather simi- lar to the body of other ornithopods, but in which the head wa
