. Expedition from the American Museum of Natural History under Dr. Barnum Brown, in the Edmonton badlands of the Red Deer River, 1912. The fossil hunters wear nets for protection against mosquitoes. , No. 18547. Soon the scow was floating between badland exposures of the Edmonton formation. Brown, used to the extensive badlands of South Dakota and Montana, thought of the vaHey as a canyon. Before the short season ended the scow was piled with specimens wrapped in the plaster and burlap casings, the first from Canada to be collected in this manner. In 1911 Brown continued his prospecting of the upper or Edmonton part of the Red Deer section with an equally successful field season. The first part of the summer of 1912 was also spent here, before moving south to the Steveville area. Among the finds made during these two and a half field seasons were the skeleton of a new duck-billed dinosaur {Saurolophus osborni), the skull of a new horned dinosaur {Anchiceratops ornatus), the incomplete skeleton of another new, and unusually small, "horned" dinosaur {Leptoceratops gracilis), partial skeletons of armoured dinosaurs (Ankylosaurus), skulls of the flesh-eating dinosaur {Albertosaurus sarco- phagus), and an incomplete skeleton of a plesiosaur {Leurospondylus uldmus), geologically the youngest member of the group discovered up to that time. Later in the summer of 1912 Brown transferred his operations to the lower or Steveville-Deadlodge Canyon area. Here he must have found the much wider badlands more to his liking. He continued working here each summer until 1915, and gathered an even more impressive collection than that obtained in 1910 and 1911. Highlights of this included two skeletons of the hooded duck-billed dinosaur {Corythosaurus casuarius), skeletons of a small duck-billed dinosaur C'Procheneosaurus''), the incomplete skull of 14
