DEPARTMENT OF VERTEBRATE PALAZONTOLOGY; FIELD 
EXPEDITIONS OF 1906. 
HE Department of Vertebrate Paleontology had three 
expeditions in the field last summer. ‘The first, under 
Mr. Barnum Brown, continued the hunt for dinosaurs 
in the Upper Cretaceous deposits of Montana. A fine 
skeleton of the Duck-billed Dinosaur Claosaurus and 
several less complete specimens of these strange look- 
ing animals were secured. ‘The Museum now possesses two mounta- 
ble skeletons and an excellent skull, representing three distinct kinds 
of Duck-billed Dinosaurs, besides many less complete specimens. Mr. 
Brown also discovered remains of a large dinosaur which appears to be 
entirely new to science and of a small species related to the Bird-catch- 
ing Dinosaur of the Jurassic period. The remarkable variety of 
dinosaurs from the Upper Cretaceous, most of them of huge size and 
bizarre appearance, is a great incentive towards continuing the search 
for them with especial vigor. It is hoped that the final results will 
enable the Museum to fill an entire exhibition hall with the dinosaurs 
of this period. In addition to the dinosaur remains a few specimens 
of the minute and very rare Upper Cretaceous mammals were secured. 
The second expedition, under Mr. Walter Granger, continued the 
exploration of the Kocene formations of Wyoming, working this year 
principally in the Washakie Basin. A number of fine specimens were 
obtained of the characteristic large mammals of this formation, the 
Kobasileus, largest and last of the uintathere race, Amynodon, the first 
of the rhinoceroses, Achanodon, a gigantic pig-like animal, Patriofelis, 
a large and powerful carnivore, and of the Eocene ancestors of the 
‘Titanotheres, besides skulls and skeletons of several of the smaller
