A New Rhinoceros From The Nebraska Miocene, Lloyd G. Tanner

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

A new species of rhinoceros, Menoceras marslandensis, is here proposed. It is based upon a nearly complete skull from the upper part of the Marsland Formation, Hemingford Group (Miocene), of Box Butte County, Nebraska. The new species was probably derived from Menoceras arikarense (Barbour), collected from the Agate Springs Quarries (Arikaree Group, Harrison Formation) of Sioux County, Nebraska, with which both Diceratherium niobrarensis Peterson and D. cooki Peterson are likely synonymous. From Menoceras arikarense, the presumed ancestral stock, Menoceras marslandensis differs in possessing the following characters: (1) very long, fused but slightly cleft, nasals, with flattened, rugose areas …

Two Feather Mite Genera (Analgoidea, Proctophyllodidae) From Birds Of The Families Oxyruncidae And Pipridae (Passeriformes, Tyranni), Warren T. Atyeo, J. Gaud

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

The genus Hemipterodectes Berla is redefined and the type species, H. squalocauda is figured. A new genus, Diproctophyllodes (type species, Proctophyllodes (Alloptes) dielytra Trouessert, 1885) is described; D. exquisita (Berla), 1959 is synomized with D. dielytra; and D. oxyrunci, new species, is described.

Biometrical Study Of Morphology And Development Of The Pennsylvanian Trilobite Ameura Sangamonensis (Meek And Worthen), Roger K. Pabian, J. A. Fagerstrom

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

Biometrical study of morphology and development in a sample of 100 cranidia, 94 pygidia, 26 free cheeks, and 9 complete specimens of the trilobite Ameura sangamonensis (Meek and Worthen) from the Bonner Springs Shale (Pennsylvanian; Missouri Series) in eastern Nebraska indicates that the dominant growth pattern was isometric. Evidence supporting this conclusion consists of rectilinear size relations among eight pairs of cranidial dimensions, three pairs of pygidial dimensions, and three pairs of dimensions of the free cheeks. Qualitative changes in pygidial morphology during development include a progressive decrease in prominence of the border, increasing width of the posterior border relative …

New Genera Related To The Genus Brephosceles Hull, 1934 (Acarina: Proctophyllodidae), Paul C. Peterson, Warren T. Atyeo

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

Five new genera are described; these and the included species are (type species listed first): Dichobrephosceles with Dermaleichus actitidis Canestrini, 1878 (=Brephosceles dolichocaulus Gaud and Mouchet, 1957, new synonymy), D. eroliae, new species (ex: Erolia alpina, England); Homeobrephosceles with Proctophyllodes (A lloptes) discosurus Trouessart, 1886, Brephosceles orthothrix Gaud and Mouchet, 1957; Onychalloptes with Proctophyllodes (Alloptes) microphaeton Trouessart, 1885, Alloptes minutus Trouessart, 1899; Aramolichus with Aramolichus foliatus, new species (ex: Aramus guarauna, Bolivia); Psilobrephosceles with Dermalichus ortygometrae Canestrini, 1878. Species included in the genus Brephosceles (s.s.) are listed; species transferred to Brephosceles are: Proctophyllodes (Pterocolus) fiagellifer discursus Trouessart, 1885; Pterocolus lambda …

Stratigraphy Of Chugwater Group (Triassic) East Side Of Bighorn Mountains, Wyoming And Montana, Robert C. Mclellan

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The Chugwater Group (Triassic), on the east side of the Bighorn Mountains of Wyoming and Montana, forms a narrow outcrop band of hogbacks. Four redbed formations are included in the Chugwater. From base to top they are: 1) Red Peak, 2) Crow Mountain, 3) Jelm, and 4) Popo Agie. The Chugwater is disconformably underlain by t];ie Goose Egg Formation (Permian) and unconformably overlain, from south to north, by the Sundance, Gypsum Spring, and Piper Formations of Jurassic Age.

The rocks of the Chugwater, in order of abundance, are: siltstone, sandstone, claystone, conglomerate, limestone, dolomite, and gypsum. Binocular microscope studies were …

Urban Geology—A Need And A Challenge, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Urban land uses are rapidly converting open land into intensively used land. Generally, in planning those uses, a comprehensive study has included everything except an evaluation of the land in three dimensions. Geologists are eminently well equipped to supply the missing data, but they must also be aware of the needs of the urban community and the kinds of information needed by planners if they are to write reports usable by planners. Urban and environmental geology is a newly expanding field in the use of geologic data to help solve some urban problems in the planning stage. It is likely …

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 …
