Lithostratigraphy And Correlation Of The Mississippian System In Nebraska, Marvin P. Carlson May 1963

Lithostratigraphy And Correlation Of The Mississippian System In Nebraska, Marvin P. Carlson

Conservation and Survey Division: Faculty and Staff Publications

The purpose of this study is to describe and correlate rocks of Mississippian age within the state of Nebraska. Shales, generally classified as "Chattanooga" and commonly referred to as Devonian or Mississippian in the northern Mid-Continent, have been included in this study, although these shales are more generally believed to be Devonian and not Mississippian by most stratigraphers and paleontologists at the present time. Since rocks of Mississippian age are present only in the subsurface of Nebraska, the basic information for this report is derived from the microscopic study of cuttings and cores from test wells drilled within the state.

The Bdellidae (Acarina) Of The Australian Realm, Warren T. Atyeo Jan 1963

The Bdellidae (Acarina) Of The Australian Realm, Warren T. Atyeo

Bulletin of the University of Nebraska State Museum (1924–2023)

Although primarily a systematic study, variations in the integumental striae and chaetotaxy of the legs are discussed. The genus Octobdellodes Atyeo, 1960 is synonymized with Bdellodes Oudemans, 1937 and the sugenus Cytobdella Mihelcic, 1958 is synonymized with Cyta von Heyden, 1826. The genus Bdellodes is divided into the subgenera Bdellodes and Hoploscirus Thor, 1937 (=Thoribdella Grandjean, 1938, new synonymy). Twenty-two species are now known to occur in New Zealand and the outlying islands. These include four known species: Bdella iconica, Bdellodes (Roploscirus) lapidaria, B. (R.) reticulata, and Cyta latirostris, and eighteen new species: Bdellodes (Bdellodes) harpax, B. (B.) oraria, …

A Middle Miocene Rhinoceros Quarry In Morrill County, Nebraska (With Notes On Hip Disease In Diceratherium), Robert M. Stecher, C. Bertrand Schultz, Lloyd G. Tanner Jan 1962

A Middle Miocene Rhinoceros Quarry In Morrill County, Nebraska (With Notes On Hip Disease In Diceratherium), Robert M. Stecher, C. Bertrand Schultz, Lloyd G. Tanner

Bulletin of the University of Nebraska State Museum (1924–2023)

Extensive deposits of fossil rhinoceros bones have been excavated from University of Nebraska State Museum collecting localities Mo-113, -114, -115, -116, and -118 some 8 1/2 to 9 1/2 miles north of Bridgeport, Morrill County, Nebraska. The fossils were associated with other faunal elements in the lower portion of the Marsland formation (middle Miocene) of the Hemingford group. The rhinoceros is considered to be Diceratherium niobrarensis Peterson, geologic variety. A pathologic right femur of D. niobrarensis provides evidence of hip disease in the medial Miocene rhinoceroses.


Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr. Jan 1962

Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.

Bulletin of the University of Nebraska State Museum (1924–2023)

Ten species of Recent mammals that formerly occurred in Nebraska have been extirpated there by European man. Surprisingly few specimens of the species concerned are preserved in museum collections. Perusal of a representative segment of the historical literature pertaining to Nebraska has revealed records of occurrence of most of the extirpated species that provide a basis for estimating the former distribution of each in the State.

Geologic And Ground-Water Reconnaissance Of The Loup River Drainage Basin Nebraska, R. T. Sniegocki, R. H. Langford Jan 1959

Geologic And Ground-Water Reconnaissance Of The Loup River Drainage Basin Nebraska, R. T. Sniegocki, R. H. Langford

United States Geological Survey: Publications

The Loup River and its tributaries drain an area of about 15,230 square miles in central Nebraska. The upper three-fifths of the drainage basin is in the Sand Hills region of Nebraska, and the lower two-fifths is in the loess plains and hills region. An eastward-thinning wedge of semiconsolidated and unconsolidated deposits of Tertiary and Quaternary age underlies the surficial dune sand and loess. These deposits, which are recharged by infiltrating precipitation, contain a tremendous volume of water at least 400 million acre-feet and annually discharge about 1.7 million acre-feet into streams. Although wells supply nearly all the water used …
