Nebraska Fossils Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division

This paper must not be mistaken for a report on the fossils of Nebraska. It is merely a circular letter to correspondents describing and figuring those fossils only which occasion frequent comment. In two recent papers of the Survey consideration was given to the common minerals and rocks of Nebraska, and it seems opportune to briefly discuss our fossils in a like manner. Probably no other State can boast of such a well-preserved and varied fauna.

Nebraska Rocks Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division

This leaflet it intended to serve as an answer to correspondents who make inquiry about the rocks of Nebraska¹. Unfortunately for those interested in such matters, the rocks of the State are few in number, and are deeply buried from view by sand and soil, so there are thousands of square miles in which even a pebble is a rarity. That our rocks are level and undisturbed is practically true. Still there are some surprisingly interesting folds and faults.

Nebraska Minerals Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division

The Minerals, Rocks, and Fossils of Nebraska, which Excite Common Inquiry, are treated brefly in leaflets numbered 37, 37a, 37b, respectively. These are intended to serve as circular letters to correspondents. Possibly they may prove to be acceptable and helpful in a measure to teachers and others who conduct parties of school children on field excursions.

A New Saber-Toothed Cat From Nebraska, Erwin H. Barbour, Harold J. Cook

Conservation and Survey Division

During the field season of 1913, while exploring the Pliocene beds of Brown County, Mr. A. C. Whitford, a Fellow in the Department of Geology, University of Nebraska, discovered the mandible of a new machaerodont cat. His work in this region was in the interest of the Nebraska Geological Survey and the Morrill Geological Expeditions.¹

Nebraska Green Quartzite An Import Ant Future Industry, Erwin H. Barbour

Conservation and Survey Division

ln southern Harlan and Franklin counties, there occur many acres of green quartzite which must be of commercial consequence when made available. It is a neglected resource upon which important industries are sure to be based. With the development of this bed in view, the Nebraska Geological Survey has examined this area. and through this leaflet wishes to place the results before possible investors.

The Round Ligament Of Nebraska Proboscideans, Erwin H. Barbour

Conservation and Survey Division

Comparisons of the acetabula of various mastodons and mammoths common to Nebraska show conclusively that absence of the round ligament is not a characteristic of the proboscidea, as generally accepted. From the specimens in our collections, there is evidence that the ligament was not on! y present, but was uncommonly large and well developed in the earlier Nebraska proboscideans. Examination of material collected since 1891, and preserved in the cabinets of the Nebraska State Museum. and the Morrill Geological Collections, makes it apparent that all Nebraska proboscideans had round ligaments, though perhaps the latest survivors did not.

A Phenomenon Of The Kansan Drift In Nebraska, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

Among the minor phenomena of the glacial drift in Nebraska there is one which, though rarely observed by the public, is of interest and should be commended to the attention of naturalists. The reference here is to certain large, well-defined masses or blocks of such materials as sand, gravel, and coarse pebbles, which occur imbedded in the drift clays along with glacial bowlders, and which presumably have been similarly transported and deposited. These masses or blocks vary widely in color, texture, and kind. They also vary from the glacial matrix in which they are found and are the more striking …

Bulletin No. 134 - The Nitric Nitrogen Content In The Country Rock, Robert Stewart, William Peterson

UAES Bulletins

In many arid sections of Western America there have been reported marked accumulations of nitrates in the cultivated soil. Hilgard,(1) who was the first to observe these accumulations, believed that the nitrates are being formed at the present time by the rapid nitrification of the organic matter contained in the soil. In Colorado there has been considerable trouble with orchards dying; the death of the trees in some cases has been attributed to the excessive accumulations of nitrates in the cultivated soil. These accumulations are due, according to Dr. Headden,(2) to the fixation of atmospheric nitrogen by bacteria now at …

Plant Tissue In The Carboniferous Shales Of Nebraska, Erwin H. Barbour

Conservation and Survey Division

While exploring the newly discovered Eurypterid beds,¹ just one mile south of Peru, Nebraska. November 8, 1912, the writer found unusual amounts of actual plant tissue of Carboniferous age. It seems incredible that it should have been preserved through such a lapse of time. Only the most resistant tissue could have endured. When freshly cleaved, the Eurypterid shales reveal innumerable bits and patches of it, mostly bright red in color.

A New Longisrostral Mastodon From Cherry County, Nebraska, Erwin H. Barbour

Conservation and Survey Division

During the season of 1914, field work in the fossil regions was pushed less vigorously than usual owing to lack of funds. Nevertheless some interesting and valuable material was obtained by the Nebraska Geological Survey, notably the great mandible of a new longirostral mastodon from Cherry County, together with associated tusk and bones.

A New Longisrostral Mastodon From Cherry County, Nebraska, E. H. Barbour

Conservation and Survey Division

During the season of 1914, field work in the fossil regions was pushed less vigorously than usual owing to lack of funds. N evertheless some interesting and valuable material was obtained by the N ebraska Geological Survey, notably the great mandible of a new longirostral mastodon from Cherry County, together with associated tusk and bones.

The mastodon constituting the basis of this paper was found in the exposnres bordering the Snake River in section 33, range 30 west, and township 32 north. The talus slope was strewn with fragments of the tusk and bone of a mastodon. This led the …
