Nebraska Fossils Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

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: Faculty and Staff Publications

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: Faculty and Staff Publications

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.

The Round Ligament Of Nebraska Proboscideans, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

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

Conservation and Survey Division: Faculty and Staff Publications

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

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

Conservation and Survey Division: Faculty and Staff Publications

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: Faculty and Staff Publications

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.

Notice Of Jelly Fishes In The Carboniferous Of Nebraska, Medusina Walcotti, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

In visiting the quarries of the State, certain quadripartite objects suggesting the form of jelly fishes have long attracted the writer's attention. They are large and coarse, and were assumed to be imitative concretions. However, the total number observed seems to strengthen the probability that they are of organic origin. In the fall of 1913, while conducting a field class through the Burlington Quarries, located about two miles northwest of South Bend, they were noted again in a new locality, and three specimens were obtained. Two of these were unusual examples, and showed sufficient structure to identify them with the …

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

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 …

Two New Fossil Dogs Of The Genus Cynarctus From Nebraska, Erwin H. Barbour, Harold J. Cook

Conservation and Survey Division: Faculty and Staff Publications

The genus Cynarctus was founded by Dr. W. D. Matthew on a nearly complete pair of lower jaws from the Pawnee Creek Beds (Middle Miocene) of Colorado, found in 1901. Since that time no new material pertaining to this genus has been reported. Dr. Matthew referred the genus to the subfamily Amphicyoninae, and to a position intermediate between the primitive bear Ursavus, and the Canidae, with primitive characters retained from its Oligocene ancestors.

Cement Manufacture In Nebraska, Erwin Hinckley Barbour

Conservation and Survey Division: Faculty and Staff Publications

It is the purpose of this paper to briefly review the history of cement manufacture in the State, to call attention to certain promising exposures of cement rock, and to report upon the first modern cement mill in Nebraska. Not that this State has been slow in recognizing cement as one of the most important modern constructional materials; or slow to recognize the need of developing its natural resources; but due rather to a combination of circumstances. For at least twenty years, many Nebraskans have had in mind the importance of establishing cement plants in this State. Furthermore encouraging inducements …
