A New Giant Camel, Titanotylopus Nebraskensis, Gen. Et Sp. Nov., Erwin H. Barbour, C. Bertrand Schultz May 1934

A New Giant Camel, Titanotylopus Nebraskensis, Gen. Et Sp. Nov., Erwin H. Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

The purpose of this bulletin is to figure and describe a .amel brought to light in the field season of 1933, which seems to be the giant of all camels found in the State. The specimen consists of the right ramus with the symphysial portion. The mandible is 26% inches long, or about the length of one's outstretched arm to the finger tips. This jaw is nine inches longer than that of Camelops kansanus. Such an extraordinary jaw indicates a camel nearly twice as large as Alticamelus altus. In reference to its unusual size we are proposing for it the …

A New Rhinoceros Mount, Trigonias Osborni, Erwin H. Barbour May 1934

A New Rhinoceros Mount, Trigonias Osborni, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

On February 9, 1934, a pair of rhinoceroses, Trigonias osborni, was installed in the Founder's Room in Morrill Hall, the Nebraska State Museum. They are figured and accorded brief consideration here in order to maintain the printed records of such acquisitions in the Nebraska State Museum. The two skeletons, carefully posed, were put in the south wall case to be associated with a pair of Diceratherium from Morrill County. and the mounted skeletons of two Brown County Te leo ceras. In this gallery two long built-in wall cases insure ample facilities for the proper installation of six rhinoceroses, for each …

A New Ovibovine, Symbos Convexifrons, Sp. Nov., Erwin H. Barbour Feb 1934

A New Ovibovine, Symbos Convexifrons, Sp. Nov., Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

In Bulletin 25, entitled The Musk-oxen of Nebraska, the writer figured and briefly catalogued the ovibovines of this State as known at that date. In the meantime an interesting new form unlike that of any species falling within our experience presents itself from the Pleistocene of Cherry County, Nebraska. The new specimen cannot be assigned a place in any of the four following genera: Preptoceras, Euceratherium, Ovibos, or Bootherium, but may possibly be referable to the genus Symbos, to which we are assigning it provisionally. It is so unlike Symbos, however, that it may be a distinct genus. …

The Nebraska Meteor And Meteorite Of August 8, 1933, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1934

The Nebraska Meteor And Meteorite Of August 8, 1933, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

At approximately 10:30 a. m., mountain standard time, on August 8, 1933, a large meteor, traveling in a westerly direction, exploded over the panhandle of Nebraska. The phenomenon was witnessed by many citizens throughout the region, and by a number of students from the University of Nebraska, who were engaged at the time in palaeontological field work in northwestern Nebraska .

The Geology And Mammalian Fauna Of The Pleistocene Of Nebraska Part I Outline Of Pleistocene Geology Of Nebraska Part Ii The Pleistocene Mammals Of Nebraska, A. L. Lugn, C. Bertrand Schultz Jan 1934

The Geology And Mammalian Fauna Of The Pleistocene Of Nebraska Part I Outline Of Pleistocene Geology Of Nebraska Part Ii The Pleistocene Mammals Of Nebraska, A. L. Lugn, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

The object of the present paper is to provide a suitable brief statement of the present state of knowledge of the Pleistocene geology of Nebraska, for an adequate understanding of the Pleistocene Mammal list, by Mr. C. Bertrand Schultz, which forms Part II of this report. The "outline" is necessarily brief and does not contain many detailed sections, nor lengthy discussions of controversial points. It is lacking in adequate detailed descriptions of new formations and may not be entirely convincing to many readers. The only excuse which the writer can offer for the shortcomings of the following pages is the …

The Mandible Of Platybeldon Barnumbrowni, Erwin Hinckley Barbour Jan 1932

The Mandible Of Platybeldon Barnumbrowni, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

Platybelodon barnumbrowni was described originally as Torynobelodon barnumbrowni.1 The Nebraska State Museum was visited and this unique specimen studied by Dr. Henry Fairfield Osborn and Dr. Walter Granger, August seventeenth and eighteenth, nineteen hundred and thirty-two. It is the opinion of both that this specimen belongs properly to their Mongolian genus Platybelodon. With certain reservations the writer wishes to defer instantly to their judgment, which is based on unequalled experience. It is perfectly apparent that this form makes a close approach to the remarkable Platybelodons found by Granger and Andrews in the Gobi Desert of Mongolia, later figured and …

A New Oreodont Slab, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1932

A New Oreodont Slab, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

A slab of pale, reddish-brown sandstone, exhibiting the articulated skeletons of two oreodonts, has been placed on display in the west corridor on the first floor of Morrill Hall. Apparently, a female and well-grown young one lay down together and perished, perhaps from disease, or from chilling winds. They must have been buried quickly, for all of the bones are present, are in perfect condition, and are in articulation, especially in the old one. In the adult the articulation is complete from the ungual phalanges of the two forefeet to the terminal caudal, even though in the figure the skeleton …

The Mounted Skeleton Of Bison Occidentalis, And Associated Dart-Points, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1932

The Mounted Skeleton Of Bison Occidentalis, And Associated Dart-Points, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

A composite skeleton of Bison occidentalis was mounted and installed in its case on the lower floor of Morrill Hall, on April 22, 1932. The skeleton in itself is attractive because of its size and excellent preservation, and is rendered additionally interesting by two dart-points, one found under the scapula, and the other under the ribs.

The Scottsbluff Bison Quarry And Its Artifacts, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1932

The Scottsbluff Bison Quarry And Its Artifacts, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

The association of artifacts with extinct bison bones in a quarry near Grand Island, Hall County Nebraska,1 and from one in Custer County, Nebraska, have already been reported.2 In the meantime, continued search has been rewarded, and a large bed of fossil bison with associated flint implements found. The discovery, if not of actual consequence, at least adds something to the accumulating evidence that Pleistocene man in America may have been a reality.

Association Of Artifacts And Extinct Mammals In Nebraska, Bertrand Schultz Jan 1932

Association Of Artifacts And Extinct Mammals In Nebraska, Bertrand Schultz

Bulletin of the University of Nebraska State Museum

During the past four years the Nebraska State Museum, under the directorship of Dr. Erwin Hinckley Barbour, has been making even more extensive palaeontological collections throughout Nebraska than heretofore. As work progresses, especially with fossil bison and mammoth, there is increasing evidence that man appeared in Nebraska much earlier than is generally believed. Two occurrences of artifacts associated with fossil bones will constitute the main theme of this paper.

The Articulated Skeleton Of Eubelodon Morrilli, Erwin Hinckley Barbour Jan 1932

The Articulated Skeleton Of Eubelodon Morrilli, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

The mounted sketleton of Eubelodon morrilli was installed in the west wall case of Elephant Hall December 31, 1931, and has attracted the attention and favorable comments of citizens and other guests. It should be explained that the case in which it is displayed is ten feet deep, sixteen feet high, and extends the length of the hall. Altogether it is a large and impressive mount which reflects credit upon its preparators, and is an important and instructive addition to the Morrill Palaeontological Collections. The pose is spirited and interesting, and the action is all that can be expected of …

Association Of An Arrow Point With Bison Occidentals In Nebraska, F. G. Meserve, Erwin H. Barbour Jan 1932

Association Of An Arrow Point With Bison Occidentals In Nebraska, F. G. Meserve, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

Of late, anthropological literature relative to the association of man and extinct mammals, especially bison and mammoth, has received many contributions from various and widely separated sources. Naturally the question has arisen whether man's advent in America is somewhat earlier than has been generally admitted, or whether certain extinct animals have persisted longer than has been realized. The issue is one of such importance and interest that even minor contributions seem desirable. It is well understood by all that the evidence, when submitted, will be properly weighed, and that conservative judges may rule out much or all of the testimony. …

The Articulated Skeleton Of Titanotherium, Erwin H. Barbour Jan 1932

The Articulated Skeleton Of Titanotherium, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

The skeleton of a titanotherium, stored since 1894, was installed in the west corridor of Morrill Hall, April 28, 1931. In the meantime the specimen has been visited by many citizens, women's clubs, and especially by delegations of school children, boy scouts, and like organizations, from various parts of the State and elsewhere. Repeated requests for a popular report on this particular specimen actuates the writing of this leaflet. Titanotheres were by far the largest creatures of Oligocene time in Nebraska. In point of size they are called gigantic, elephantine, and titanic. The titans of Greek mythology were giants, and …

The American Mastodon With Mandibular Tusks, Erwin H. Barbour Mar 1931

The American Mastodon With Mandibular Tusks, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

Mastodons and mammoths, represented by their relics, are so frequently exposed by shovel, plow, road grader, dredge, and rains, that they have become household words. They are plainly the commonest and best-known vertebrate fossils. They were fortuitously entombed, and are now accidently found. Their relics, though numerous, never represent the grand total that lived. Indeed, it was a rare individual that fell where circumstances favored rapid interment and consequent preservation; the grand majority fell in the open where their bones suffered rapid and complete decay. The American mastodon occupies a position between the long-jawed, long-skulled, four-tusked ancestor called Palaeomastodon, and …

A Morning's Consignment Of Proboscidean Freight, Erwin Hinckley Barbour Jan 1931

A Morning's Consignment Of Proboscidean Freight, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

In the accompanying cut the array of great tusks outlined through their rough crates may lack attractiveness, nevertheless the assemblage is quite out of the ordinary, and seems worth recording in bulletin form. In all museums, and like institutions, freight and express deliveries are matters of daily routine; however, the morning's freight shown in the cut is unique. Herein is represented the more showy portion of the proboscidean freight received at the Nebraska State Museum in a single consignment, in the field season of 1930. The other boxes of mammoth skulls, jaws, and bones, received at the same time, are …

The Giant Beaver, Castoroides, And The Common Beaver, Castor, In Nebraska, Erwin Hinckley Barbour Jan 1931

The Giant Beaver, Castoroides, And The Common Beaver, Castor, In Nebraska, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

Respecting the giant beaver, Castoroides, in Nebraska, four occurrences can be reported. Of rodents in general the dawn. was in the early Eocene, at which time there were in existence certain squirrel-like members of the order. Rodents are a persistent group, and are among the smallest, most distinctive, most numerous and widely distributed orders of terrestrial mammals. No other order boasts of so many species, the number being between nine hundred and one thousand. In spite of wide divergencies and modifications adapting them to various modes of life, such as climbing, burrowing, swimming, flying, leaping, and running, there is remarkable …

The Milford Mastodon, Mastodon Moodie I, Sp. Nov. A Preliminary Report, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

In developing the hydro-electric plant of the Iowa and Nebraska Light and Power Company, a number of dams were thrown across the Blue River and its branches. One of these, known as Dam No.7, was built across the West Blue, about nine miles southwest of Milford, Seward county, Nebraska. This dam raised the water well above the ordinary river level, and flooded fifteen or twenty acres of valley land. The impounded water soaked into, and washed against, the base of a twenty-foot bank of cross-bedded sand, until some time during the winter of 1931, a portion of the bank near …

A New Crinoid Slab, A Bit Of Mississipian Sea Bottom, Erwin Hinckley Barbour Jan 1931

A New Crinoid Slab, A Bit Of Mississipian Sea Bottom, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

Crinoids are popularly known as stone-lilies, featherstars, and sea-lilies. The word lily is a misnomer, and many, misled by the name and by the lily-like form, associate crinoids with the plant kingdom. The name, feather-star, seems explicit for it refers to the feathery arms surrounding the cup or calyx, and expresses relationship to the starfishes and their kind. The cup is attached to a stem, and the stem is anchored to the ocean floor by so-called roots, which are really hold-fasts, or anchors. These features may be seen in the diagram at the end.

A New Amebelodont, Torynobelodon Barnumbrowni, Sp. Nov. A Preliminary Report, Erwin Hinckley Barbour Jan 1931

A New Amebelodont, Torynobelodon Barnumbrowni, Sp. Nov. A Preliminary Report, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

The subfamily of longirostrine mastodonts known as the Amebelodontinae have been so recently discovered and described that as yet they; are little known by the citizens of this state. They are most briefly and directly described as shovel-tusked mastodons. The first one found, namely Amebelodon fricki, was secured in April 1927, and was published June 1927. In the meantime, many other examples of Amebelodonts have been added to the Morrill Palaeontological Collections of the Nebraska State Museum. The exact number cannot be stated until the material shipped in from the field during the current season is unpacked, cleaned, and identified. …

Evidence Of Dinosaurs In Nebraska, Erwin Hinckley Barbour Jan 1931

Evidence Of Dinosaurs In Nebraska, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

Nebraska has long been a collecting ground famous for its fossil mammals, but as yet no dinosaurian bones have been reported, nor have they been expected. The distal end of a finely preserved femur, however, has recently been brought to light, supposedly occurring in position in the Dakota formation of eastern Nebraska. It was discovered, collected, and donated by Mr. J. B. White, (University of Nebraska, Law, class of 1899) on his farm two miles south of Decatur, in northeastern Burt County, near the Missouri River. It was found in undoubted Dakota sand associated with many leaf impressions. This is …

The Musk-Oxen Of Nebraska, Erwin Hinckley Barbour Jan 1931

The Musk-Oxen Of Nebraska, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

The remains of no less than eight fossil musk-oxen are already known in Nebraska, of which one is preserved in the Museum at Hastings, Nebraska, and seven in the State Museum at Lincoln. This is a large number to be recorded in anyone state. As late as 1891 authors wrote that but two examples of musk-oxen were known in the United States, one from Kentucky, and one from Arkansas, if, indeed, they be valid species. Now that pioneer days are well behind this commonwealth, and that there is a growing sentiment for exploration and proper display of the State's resources, …

Amebelodon Sinclairi Sp Nov., Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

Amebelodonts are so new and so rare that even fragmentary facts relative to the group seem worth publishing. The specimen under consideration is a mandibular tusk found on the farm of Mr. A. S. Keith, Freedom, Frontier County, Nebraska, on the Morrill Geological Expedition of 1928, and is numbered 1-17-7-28, S. and L., the collectors being Bertrand Schultz and John LeMar, both of the class of 1931, the University of Nebraska. The formation was Late Pliocene or Pleistocene.

The Mandible Of Amebelodon Fricki, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

The type specimen of the genus Amebelodon is installed in the Nebraska State Museum, the University of Nebraska, Lincoln. It consists of a mandible with tusks and teeth, all of which are dense and perfect, barring minor cracks and breaks. One toe bone and part of a rib found associated with this mandible may belong to this animal. It was discovered by Mr. A. S. Keith on his farm near Freedom, Frontier County, Nebraska; was secured for the palaeontological collections of Hon. Charles H. Morrill by Mr. Phillip Orr, April 4, 1927; was briefly described and figured in a Museum …

Torynobelodon Loomisi, Gen Et. Sp. Nov., Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

The group of proboscideans which we have called the shovel-tuskers or Amebelodonts, was announced in June, 1927,1 following the discovery of Amebelodon fricki. In the field season of 1928, two additional species were found which are represented by mandibular tusks. One of these is a tip of a large and unique tusk, numbered 2-3-9-28, S. and L., the collectors being Bertrand Schultz and John LeMar, both of the class of 1931, the University of Nebraska. It was found within 200 to 300 yards of the spot on his farm where Mr. A. S. Keith, Freedom, Frontier County, Nebraska, found …

The Mandibular Tusks Of Amebelodon Fricki, Erwin H. Barbour Jan 1929

The Mandibular Tusks Of Amebelodon Fricki, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

The ponderous mandible of the great shovel-tusked mastodon, Amebelodon fricki, was figured and described before it was practicable to remove the plaster cinches. In the meantime, this rare specimen has lain on its sand table awaiting the time when sections and casts could be made before mounting it permanently. A rare specimen, especially if heavy, unwieldy, and fragile, is rarely dismantled for study after it is mounted and installed in its case. A gelatine cast of the alveoli has been made, and through the assistance of Mr. Murray Jerome Roper, a cast of the left mandibular tusk has just been …

Directory Of Certain Alumni The Department Of Geology And Geography The University Of Nebraska, E. F. Schramm

Bulletin of the University of Nebraska State Museum

In the Department of Geology and Geography, The University of Nebraska, there have been over 10,000 registrants between the years 1891 and 1926. So many inquiries have been received concerning alumni and their addresses that it seems advisable to publish this directory. The list is necessarily incomplete since many of the alumni have not informed the Department respecting their addresses and change of positions. Out of the total number of those who have pursued professional vocations the following have kept in close touch with the Department.

Archidiskodon Maibeni, Erwin H. Barbour Jan 1926

Archidiskodon Maibeni, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

Archidiskodon maibeni was first described in Bulletin 10 of the Nebraska State Museum under the title" Skeletal Parts of the Columbian Mammoth, Elephas Maibeni." * Dr. Henry Fairfield Osborn finds it expedient to found a new genus, Archidiskodon, to include the earlier and more primitive mammoths. Hence the change in the generic name. t'Mammoths and modern elephants have long been grouped together under 'the genus Elephas. Subdividing the genus does not necessarily do away with this convenient and rather familiar old arrangement.
