Sand Fulgurites From Nebraska Their Structure And Formative Factors, Abram E. Anderson
Sand Fulgurites From Nebraska Their Structure And Formative Factors, Abram E. Anderson
Bulletin of the University of Nebraska State Museum (1924–2023)
So much has been written during the past century on the origin, structure and occurrence of fulgurites, or lightning tubes, found in many parts of the world that it would seem as though little remains to be added to the literature on the subject; but the discovery of a considerable number of unusually large and complete specimens in Holt and Stanton Counties, Nebraska, which exhibit remarkable definition of the particular features that have occasioned so much controversy regarding their formative processes, has added an important type to the representatives of this phenomenon and afforded clearer interpretation of the origin of …
Skeletal Parts Of The Columbian Mammoth Elephas Maibeni, Sp. Nov., Erwin Hinckley Barbour
Skeletal Parts Of The Columbian Mammoth Elephas Maibeni, Sp. Nov., Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
The skeletal parts of Elephas columbi are said to be unknown, although teeth, jaws, and skulls are common enough. Columbi is a mammoth of southern adaptation, hence its parts are found from Nebraska southward. Elephas columbi occurs abundantly throughout the State and many examples are preserved in the Nebraska State Museum, as will be seen in an accompanying list.
Tetrabelodon Abell, Sp. Nov., Erwin Hinckley Barbour
Tetrabelodon Abell, Sp. Nov., Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
Brown County, Nebraska, which has been so prolific of long-jawed mastodons, has yielded another form which seems to be new and which may throw light on certain small tusks that occur where Tetrabelodon bones abound. Heretofore, we have considered these to be embryonic, but they show apparent wear, and in other respects they are enigmatic, and at best, atypical. Tetrabelodon tusks proper, however young, are typical, and are obviously tusks in miniature. The tusks in doubt are of varying lengths and about the diameter of one's thumb, but taper backwards, are worn to a bluntly oblique point, and are slightly …
Hackberry Conglomerate A New Nebraska Rock, Erwin Hinckey Barbour
Hackberry Conglomerate A New Nebraska Rock, Erwin Hinckey Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
In the cabinets of the Nebraska State Museum are several excellent rock specimens, which at first sight pass for pisolite, which they simulate. Scrutiny shows that they are hackberry seeds in sand, cemented by lime and clay into a firm, compact rock. The term hackberry conglomerate seems apropos.
Notes On Nebraska Fulgurites, Erwin Hinckley Barbour
Notes On Nebraska Fulgurites, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
Some six or eight years ago the writer contemplated a study of Nebraska fulgurites, both in the field and in the laboratory. In the meantime however, it proves to be superfluous for, after supplying Mr. A. E. Anderson, of the American Museum of Natural History, with certain material and data he proceeded in a masterful way on a technical inquiry, and it is with pleasure that, although delayed in publication, his findings follow in Bulletin 7 of the Nebraska State Museum. The present paper will deal as briefly as possible with the mode of occurrence and gross structure.

Manganese Fulgurites, Harold J. Cook
Manganese Fulgurites, Harold J. Cook
Bulletin of the University of Nebraska State Museum (1924–2023)
During August, 1924, while doing reconnaisance work near the head of Chugwater Creek, Wyoming, on the ranch of Mr. J. L. Jordon, the writer's attention was called to some unusual and interesting specimens found in a limited area, perhaps an acre or so, on the slope of the small butte flanking the Chugwater Valley. The hills of the region are of Tertiary age, the particular spot under consideration being Oligocene, the Brule stage, or Oreodon beds.
An American Fossil Giraffe Giraffa Nebrascensis, Sp. Nov., W. D. Matthew, E. H. Barbour
An American Fossil Giraffe Giraffa Nebrascensis, Sp. Nov., W. D. Matthew, E. H. Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
A fragment of the lower jaw of a large fossil mammal with two well-worn teeth was dug up in June 1918, at a depth of 20 feet, while digging a cess pool at Bradshaw, York County, Nebraska.
Elephas Scotti A New Primitive Mammoth From Nebraska, Erwin Hinckley Barbour
Elephas Scotti A New Primitive Mammoth From Nebraska, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
On February 18,1922, the mandible of an unusually primitive mammoth was secured for the palaeontological collections of Mr. Hector Maiben by Mr. E. T. Engle. The specimen was found in Aftonian gravel on the farm of Mr. E. J. Hartman, five miles south of Staplehurst, Seward County, Nebraska. It is numbered 18-2-22 in the accession book of the Nebraska State' Museum.

A Preliminary Report On The Nebraska State Museum, Erwin H. Barbour
A Preliminary Report On The Nebraska State Museum, Erwin H. Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
The Nebraska State Museum has been established a sufficient number of years to make it widely known throughout the state, both by reputation and by personal visits. Incident to a growing clientele and an expanding correspondence, it is expedient that a concise circular letter be issued in bulletin form. Such a pamphlet can be promptly forwarded to inquirers and will offer obvious advantages over individual replies.

Report On The Work Of The Morrill Geological Expeditions Of The University Of Nebraska, Carrie Adeline Barbour
Report On The Work Of The Morrill Geological Expeditions Of The University Of Nebraska, Carrie Adeline Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
Through the generosity of the Hon. Charles H. Morrill, of Lincoln, the expeditions sent out from the University of Nebraska, known as the Morrill Geological Expeditions, have become a permanent organization of the University. Therefore, it is but a fitting mark of respect that reports of these expeditions be given to the Nebraska Academy of Science from time to time in order that they may become matters of record. Introductory to this work, a private geological excursion was undertaken in June of 1891, by Mr. Erwin Hinckley Barbour in the interest of the University of Nebraska. At this time the …
Report On The Initial Work Of The State Geological Survey Of Nebraska, Erwin Hinckley Barbour
Report On The Initial Work Of The State Geological Survey Of Nebraska, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
IN a State such as Nebraska where there is no 'mineral'--a term which in the west has come to mean gold and silver-bearing--it is difficult to convince the masses that there is the least possible economic importance in a State geological survey.
If 'mineral' did occur, apathy could much more easily be overcome, and the appeals for a survey would find more willing and receptive ears. But something stronger than apathy is encountered in the prejudice which has been engendered against a State survey by men who have sought heretofore to establish such for the evident purpose of holding office, …
Notice Of The Occurrence Of Nyctale Richardsoni, Richardson's Owl, In Nebraska, Erwin Hinckley Barbour
Notice Of The Occurrence Of Nyctale Richardsoni, Richardson's Owl, In Nebraska, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
THE occurrence in this region of Richardson's owl, Nyctale Richardsoni, seems to be entirely established by the recent capture of one in Lincoln. This is a long distance below its southern limit, and its appearance is something of a surprise.
A New Habitat Of The Black-Throated Rock Swift, Micropus Melanoleucus, Erwin Hinckley Barbour
A New Habitat Of The Black-Throated Rock Swift, Micropus Melanoleucus, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
As curator of the museum, I have just procured for the State University of Nebraska a set of bird-skins prepared during the past summer, among which are five skins that must be of interest to ornithologists. They verify the discovery made by Professor Lawrence Bruner of the University of Nebraska, that the White-throated Rock Swift builds and breeds in the precipitous bluffs around Squaw Canon, Sioux Co., Nebraska, and, what is more likely, throughout the Pine Ridge regions, as Professor Bruner has observed them also at Crow Butte, near Crawford, Nebraska.

The Aerosphere As A Network Connector Of Organisms And Their Diseases, Jeremy D. Ross, Eli S. Bridge, Diann J. Prosser, John Y. Takekawa
The Aerosphere As A Network Connector Of Organisms And Their Diseases, Jeremy D. Ross, Eli S. Bridge, Diann J. Prosser, John Y. Takekawa
United States Geological Survey: Staff Publications
Aeroecological processes, especially powered flight of animals, can rapidly connect biological communities across the globe. This can have profound consequences for evolutionary diversification, energy and nutrient transfers, and the spread of infectious diseases. The latter is of particular consequence for human populations, since migratory birds are known to host diseases which have a history of transmission into domestic poultry or even jumping to human hosts. In this chapter, we present a scenario under which a highly pathogenic avian influenza (HPAI) strain enters North America from East Asia via postmolting waterfowl migration. We use an agent-based model (ABM) to simulate the …
