NEW DINOSAURS FOR THE AMERICAN MUSEUM 



By \V. D. Matthew 



FOR the past three summers the Museum has ha<^l an expedition in 

 Alberta, Canada, searching for dinosaurs in the Cretaceous forma- 

 tions of the Red Deer River. This expetUtion in charge of Mr. 

 Barnum Brown, associate curator of fossil reptiles, lias secured a fine series 

 of specimens including a number of more or less complete skeletons of 

 dinosaurs, some of them new, others related to the Cretaceous dinosaurs of 

 Wyoming and Montana. The collection is already large and will be doubled 

 by the results of this season's work; its preparation and study will not be 

 completed for some time to come. The specimens of the following list have 

 been placed on exhibition on the fourth floor in the case opposite the 

 elevator. 



1. Alheriosaurus skull, hind limb and part of tail. This was a great carnivorous dino- 

 saur related to the Tyrannosaunts and more distantly to the AUonaurua and intermediate 

 between the two in size. 



2. Small ceratopsian Cnew). This is related to the huge horned dinosaurs, but is quite 

 a small animal. A fragmentary skeleton was secured of which the fore limb and tail have 

 been placed on exhibition, the rest being very much broken up. 



3. Crested dinosaxir Sauralophus (new). A complete articulated skeleton, of which the 

 sktill and jaws are placed on e.xliibition. It is related to the -duck-bill dinosaurs but had a 

 crest along the back and a great bony spine at the Ijack of the skull. 



4. Skulls and end of tail of armored dinosaurs. These are perhaps the most remarkable 

 of Mr. Brown's discoveries. The whole body was covered with heavy armor-plates, con.soli- 

 dated on the skull and the tip of the tail into a solid bony mass. This group of dinosaiu-s 

 has become known to science only within the last few years, chiefly through Mr. Brown's 

 explorations and studies. The specimens secured will probably enable us to restore the 

 entire skeleton of the largest of the group, Ankylosaurus. 



The novel methods adopted by Mr. Brown to explore this formation 

 ■v\'ere outlined by him in the Journal for December, 1911. The friendly 

 attitude of the Canadian Geological Survey, to whose fiekl parties we owe 

 our first knowledge of the fossil riches of this territory, has been of material 

 assistance. 



A PEOPLE'S MUSEUM OF EUROPE 



By waiter (irdin/cr 



OF the natural history museums of Europe there is one which should 

 be of especial interest to members and friends of the American 

 Museum, because in the relations existing between the nmscuni 

 and the public it seems more nearly to approach our own than any other 

 institution of its kind. This is the Museum of the Senckenberg Natural 

 History Society of Frankfurt-am-Main, Germany. In some respects it is 

 unique among natural history museums. The American Museum, like 

 the British Museum and our National INIuseum, has a two-fold object, 

 scientific research and public instruction. University museums here and
