American Tertiary mollusks of the genus Clementia
W. P. Woodring
1927, Professional Paper 147-C
Aside from its value as an aid in determining the age of Tertiary beds, the chief interest of the genus Clementia lies in the anomalous features of its present and former distribution. An attempt is made in this paper to trace its geologic history, to point out its paleobiologic significance,...

An early Eocene florule from central Texas
Edward Wilber Berry
1925, Professional Paper 132-E
In 1916 I described a florule collected by Alexander Deussen and L. W. Stephenson at the town of Earle, in Bexar County, Tex. This florule was tentatively considered of Midway age by these geologists, and examination of the fossil plants tended to confirm this assignment, particularly because of their lack...
Correlation of the Eocene formations in Mississippi and Alabama
Wythe Cooke
1925, Professional Paper 140-E
During Eocene time the site of the boundary between the States of Mississippi and Alabama fell within the transition zone between the Mississippi embayment and the open Gulf of Mexico. That different types of deposition proceeded simultaneously within these two regions may be inferred from the different facies which...
