Some American Cretaceous fish scales, with notes on the classification and distribution of Cretaceous fishes
T.D.A. Cockerell
1919, Professional Paper 120-I
Fish remains are extremely abundant in several Cretaceous formations of the Rocky Mountains and Great Plains, but except in the Niobrara formation of Kansas, a fish skeleton well enough preserved for description or identification is the greatest rarity. The fishes are represented by separate scales, in some places associated...
Relations of late Paleozoic and early Mesozoic formations of southwestern Montana and adjacent parts of Wyoming
D. Dale Condit
1919, Professional Paper 120-F
The object of this paper is twofold - to present evidence found in southwestern Montana concerning the great Jurassic base-leveling and its bearing on the solution of certain stratigraphic problems involving late Paleozoic, Triassic, and Jurassic formations, and to set forth the relations of those formations to beds in western...

A contribution to the geology of northeastern Texas and southern Oklahoma
Lloyd William Stephenson
1919, Professional Paper 120-H
The region in central and northeastern Texas and southern Oklahoma known as the Black and Grand prairies abounds in features of interest to physiographers, geologists, and paleontologists, and the pioneer investigators of this region must have experienced renewed satisfaction in each day's exploration. The reports of Joseph A. Taff,...
Geology and ore deposits of the Tintic mining district, Utah
Waldemar Lindgren, G. F. Loughlin, V. C. Heikes
1919, Professional Paper 107
Tintic, Park City, and Bingham have always been the three great silver-lead producing districts of Utah. Of late years Bingham has also become one of the most prominent copper districts of the world, and Tintic has likewise entered the ranks of the great copper camps....
New graphic methods for determining the depth and thickness of strata and the projection of dip
Harold S. Palmer
1919, Professional Paper 120-G
Geologists, both in the field and in the office, frequently encounter trigonometric problems the solution of which, though simple enough, is somewhat laborious by the use of trigonometric and logarithmic tables. Charts, tables, and diagrams of various types for facilitating the computations have been published, and a new method may...
Some American Jurassic ammonites of the genera Quenstedticeras, Cardioceras, and Amoeboceras, family Cardioceratida

The species cordiforme Meek and Hayden, distans Whitfield, canadense Whiteaves, and dubium Hyatt (probably including whitneyi J. P. Smith), variously assigned to the genera Amaltheus, Quenstediceras, Amoeboceras, and Cardioceras, and subtumidum Whitfield and Hovey, assigned to Aegoceras, include all the previously described species of Jurassic ammonites that are considered in...

Geology of northeastern Montana
Arthur J. Collier
1919, Professional Paper 120-B
A large region in northeastern Montana has never been thoroughly explored by geologists, owing to the fact that it is a part of the Great Plains and the belief that it is too monotonous and uninteresting to tempt anyone to turn aside from the pronounced geologic features a little farther...
Baked shale and slag formed by the burning of coal beds
G. Sherburne Rogers
1918, Professional Paper 108-A
The baking and reddening of large masses of strata caused by the burning of coal beds is a striking feature of the landscape in most of the great western coal-bearing areas. The general character and broader effects of the burning have been described by many writers, but the fact that...

The Flaxville gravel and its relation to other terrace gravels of the northern Great Plains
Arthur J. Collier, W. T. Thom Jr.
1918, Professional Paper 108-J
In Nebraska and South Dakota there are widespread deposits of gravel and other material, largely superficial and generally uninitiated, known as the White River, Arikaree, Ogalalla, and other formations, which range in age from Oligocene to Pleistocene. West of these deposits, on the flanks of the Rocky Mountains, are several...
