Precambrian Well Data In Nebraska, Including Rock Type And Surface Configuration, Marvin P. Carlson
Precambrian Well Data In Nebraska, Including Rock Type And Surface Configuration, Marvin P. Carlson
Conservation and Survey Division: Faculty and Staff Publications
This bulletin presents, in tabular form, information relating to the Precambrian surface and includes a configuration map of this surface in Nebraska. The data from all of the 1460 deep tests reaching the Precambrian as of January 1, 1966 are listed. It is anticipated that further studies utilizing this data will be made due to the important influence of the Precambrian surface on later sedimentation and structure and the possibility of minerals of economic importance being present in Precambrian rocks. Specific information for each well and samples, except as noted in the tabulation, are on file and available for study …
A Revision Of The Bees Of The Genus Andrena Of The Western Hemisphere. Part I. Callandrena. (Hymenoptera: Andrenidae), Wallace E. Laberge
A Revision Of The Bees Of The Genus Andrena Of The Western Hemisphere. Part I. Callandrena. (Hymenoptera: Andrenidae), Wallace E. Laberge
Bulletin of the University of Nebraska State Museum (1924–2023)
This paper is the first part of a monograph of the bee genus Andrena in the western hemisphere and treats the subgenus Callandrena. Available data regarding phylogeny, distribution, biology, and flower preferences are presented together with keys to separate the species, diagnoses and descriptions of the species and discussions of geographic variation when applicable. Seventy-nine species and one subspecies are recognized. Sixteen names are relegated to synonymy, one to homonymy and eight are removed from the subgenus Callandrena. The thirty-nine species new to science are: aerifera, aeripes, afimbriata, ardis, auripes, balsamorhizae, beameri, bilimeki, bullata, calvata, dreisbachorum, fulminea, fulminoides, …
A New Species Of Rhinoceros, Aphelops Kimballensis, From The Latest Pliocene Of Nebraska, Lloyd G. Tanner
A New Species Of Rhinoceros, Aphelops Kimballensis, From The Latest Pliocene Of Nebraska, Lloyd G. Tanner
Bulletin of the University of Nebraska State Museum (1924–2023)
An uncrushed skull and associated skeletal elements of a very large rhinoceros are the basis for the description of a new species of Aphelops from Frontier County, Nebraska. The major differences are: the skull is much larger in most dimensions than other Aphelops; it has an extremely elevated occipital region in comparison to Aphelops mutilus; the narial notch is retracted to a point perpendicular to the center of molar one; and the teeth are more hypsodont than any other species of this genus. The sediments which yielded the skull and skeletal parts are considered to be Kimballian in …

The Monotypic North American Subgenus Larandrena Of Andrena (Hymenoptera: Apoidea), D. W. Ribble
Bulletin of the University of Nebraska State Museum (1924–2023)
Larandrena contains a single species, A. miserabilis Cresson. This small, common Andrena is found throughout most of the United States and southern Canada in the spring. The subgeneric position, nomenclature, redescription. variation, notes on the biology, parasites, range, seasonal activity and plant host records are included. A. rniserabilis is thought to be an important pollinator of fruit trees.
Citellus Kimballensis, A New Late Pliocene Ground Squirrel, Douglas C. Kent
Citellus Kimballensis, A New Late Pliocene Ground Squirrel, Douglas C. Kent
Bulletin of the University of Nebraska State Museum (1924–2023)
A new fossil sciurid, Citellus kimballensis, is described. This new species was found in the Kimball Formation, uppermost Ogallala (very late Pliocene) at the University of Nebraska State Museum Collecting Locality Cn-1O1, northeast of Sidney, Cheyenne County, Nebraska. Characters of the dentition and skull of C. kimballensis are compared with those of other species of the genus, and with those of Cynomys.
The Brule-Gering (Oligocene-Miocene) Contact In The Wildcat Ridge Area Of Western Nebraska, C. Bertrand Schultz, Charles H. Falkenbach, Carl F. Vondra
The Brule-Gering (Oligocene-Miocene) Contact In The Wildcat Ridge Area Of Western Nebraska, C. Bertrand Schultz, Charles H. Falkenbach, Carl F. Vondra
Bulletin of the University of Nebraska State Museum (1924–2023)
The contact between the Brule Formation (Oligocene) and the Gering Formation (Miocene) can be readily distinguished in the Wildcat Ridge area, as elsewhere in western Nebraska. At the critical fossiliferous exposures at Castle Rock in Scotts Bluff County, the contact on the south face between the two formations is defined as 129 feet above the base of the "Upper Ash" bed, which corresponds to the upper portion of Darton's (1899, PI. C, Fig. D, following p. 754) "sandy phase" in the upper part of the Brule. Certain key beds in the Gering Formation can be traced laterally from a channel …

Revision Of The Classification Of The Pleistocene Deposits Of Nebraska, E. C. Reed, V. H. Dreeszen
Revision Of The Classification Of The Pleistocene Deposits Of Nebraska, E. C. Reed, V. H. Dreeszen
Conservation and Survey Division: Faculty and Staff Publications
The first major contribution of the Conservation and Survey Division to Pleistocene stratigraphy was that of A. L. Lugn (1935) who established a classification of the periglacial deposits of the state and related these deposits to the glacial stages. G. E. Condra and E. C. Reed (1950) used information aquired during the 1935-1950 period in making important revisions to Lugn's classifications. This report was a further revision based on studies made from 1950 to publication date (1965).
