Tertiary Coniferous Woods Of Western North America, George F. Beck Aug 1945

Tertiary Coniferous Woods Of Western North America, George F. Beck

All Faculty Scholarship for the College of the Sciences

Almost four decades have elapsed since Platen (1908), the German paleobotanist, published his report upon the fossil woods of the western United States. Since then no over-all treatment of these materials has been attempted. although Platen overlooked the Pacific Northwest with its abundance of Tertiary petrified woods. The purpose of this paper is to bring knowledge of the western coniferous woods of the Tertiary up to date. In this effort the writer recognizes that much of this information has been accumulated incidentally in the study of the Russell Petrified Forest series of central Washington, and that it is not as …

Nyssa Woods Of The Pacific-Northwest Tertiary, George F. Beck Feb 1945

Nyssa Woods Of The Pacific-Northwest Tertiary, George F. Beck

All Faculty Scholarship for the College of the Sciences

The nyssa gums are one of the modern genera of trees most certainly present among the petrified woods and forests of the Pacific Northwest. Almost every collection from the mid-Tertiary of this region contains a few specimens of typical tupelo or sour gum. These are fine-grained woods which to the unaided eye may be mistaken for conifers.

Ancient Maples Of The Central Washington Region, George F. Beck Nov 1944

Ancient Maples Of The Central Washington Region, George F. Beck

All Faculty Scholarship for the College of the Sciences

When I began work on the petrified logs of the general Vantage area some 13 years ago, it became apparent at once that maple-like woods are commonplace in the main (Vantage) raft forest and slightly less abundant in two rooted units of the Yakima Canyon. So widely do these woods range throughout the structural variations found in modern maples that little success has attended the efforts to assign them to nominal species. The extremes can readily be established but few hints exist as to the boundaries between them.

Two Newly Discovered Conifers, George F. Beck Apr 1944

Two Newly Discovered Conifers, George F. Beck

All Faculty Scholarship for the College of the Sciences

Two genera of coniferous wood, apparently not listed among the Tertiary woods of the western states, have been recognized in the Percy Train collections from Rainbow Ridge, northwestern Nevada. These two, Tsuga (hemlock) and Chamaecyparis (cedar) bring up to 14 the genera of coniferous wood more or less certainly identified from the period and area in question.

Status Of Tertiary Woods Of The Western States Representing The Juglandaceae, George F. Beck Apr 1944

Status Of Tertiary Woods Of The Western States Representing The Juglandaceae, George F. Beck

All Faculty Scholarship for the College of the Sciences

For many years there has been uncertainty concerning the generic status of some fossil leaves belonging without question to the walnut family as a whole. A review of the woods of Juglandaceae as they have appeared in Tertiary horizons of the western states has suggested which genera are present, and in what proportions their leaves (or other remains) might be expected to appear.

A Review Of The Daimonelix Problem, C. Bertrand Schultz Mar 1942

A Review Of The Daimonelix Problem, C. Bertrand Schultz

University Studies (University of Nebraska) (1888–1984)

THE first paleontological expedition of the University of Nebraska State Museum was organized in the summer of 1891 and was led by Erwin H. Barbour, now Director Emeritus of the Museum. The most important and interesting discoveries made during the season were some very peculiar spiral fossils called by the field party "Devil's Corkscrews," or Daimonelix,l which were found in the Miocene deposits near Harrison in Sioux County, Nebraska. During the fifty years that have intervened scientists have tried to determine the origin of these strange forms. Several controversies arose, and although various theories have been proposed, none as yet …

A New Fossil Bovid From Nebraska With Notice Of A New Bison Quarry In Texas, C. Bertrand Schultz Jan 1941

A New Fossil Bovid From Nebraska With Notice Of A New Bison Quarry In Texas, C. Bertrand Schultz

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

An interesting and unique bovid skull was reported to the staff of the University of Nebraska State Museum in 1938 by Mr. Alvin McReynolds of Nehawka, Nebraska. The specimen was found in 1933 in a ravine north of Nehawka by Messrs. Merritt and Harold Dodson, brothers. Although the skull was not in place, it appears to have been washed out of a nearby Pleistocene clay deposit by floodwaters. The specimen is well preserved and is of a dark brown, almost black color. In 1938 it was loaned to the Museum for study and photographing but was not obtained as a …

The Ancestral Ursid, Hemicyon, In Nebraska, Edwin H. Colbert

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

During the summer of 1928, a University of Nebraska State Museum field party, composed of Dr. A. L. Lugn and the writer, made a collection of upper Miocene and lower Pliocene mammals in Brown and Cherry counties, Nebraska. This collection was sponsored and made possible by the generosity of the late Hon. Charles H. Morrill.

A Shovel-Tusked Mastodon, Arnebelodon Fricki, From Kansas, Erwin Hinckley Barbour, Claude W. Hibbard Jan 1941

A Shovel-Tusked Mastodon, Arnebelodon Fricki, From Kansas, Erwin Hinckley Barbour, Claude W. Hibbard

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

Since the Amebelodontinae were first announced (Barbour 1927), a number of examples of the genus Amebelodon have presented themselves in various parts of Nebraska, Colorado, and in several places in Kansas. Thus its range has already been materially extended, many skeletal parts added, and the hope kindled that knowledge of this remarkable group of proboscideans is destined to be greatly enriched within the next few years. As may be seen in the accompanying lists of the known parts of Amebelodon preserved in various museums, there are already at hand the bones necessary for the assemblage of a nearly complete composite …

A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1941

A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

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

The genus Sphenophalos was described by John C. Merriam (1909, p. 319-30), who based his description on a fragmentary horn-core (Uni. of Calif. No. 11887) from the late Tertiary deposits near Thousand Creek in northern Humbolt county, Nevada. Knowledge of Sphenophalos, however, is still confined to this single, fragmented type horn-core (Frick 1937, p. 472) and other fragmental specimens (Furlong 1932, p. 27-36).

The Pipy Concretions Of The Arikaree, C. Bertrand Schultz Jan 1941

The Pipy Concretions Of The Arikaree, C. Bertrand Schultz

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

The pipy concretions of the Arikaree (lower Miocene) of Nebraska and adjacent states were first described by Nelson Horatio Darton (1899, p. 743) as "characteristic layers of hard, fine-grained, dark-gray concretions, often consisting of aggregations of long, irregular, cylindrical masses" (see Figures 30, 32, 34, and 35). The individual pipes vary in diameter from a few inches to several feet, and in length from a few inches to a hundred yards or more. Tests demonstrate that pipy concretions are composed of sand cemented by calcium carbonate. When dipped in acid the cement is dissolved and the concretion is reduced to …

The White River Oligocene Rodent Diplolophus, Erwin Hinckley Barbour, Thompson M. Stout Jan 1939

The White River Oligocene Rodent Diplolophus, Erwin Hinckley Barbour, Thompson M. Stout

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

The rich and varied nature of the mammalian faunas of the White River Oligocene has been recognized for many years, but the exact geologic succession is only now becoming known. In these faunal assemblages the rodents and lagomorphs appear to have been important elements, perhaps numerically as abundant in the Oligocene as are these same groups at present.

Report Of Progress Of The Nebraska State Museum, Erwin H. Barbour Jan 1938

Report Of Progress Of The Nebraska State Museum, Erwin H. Barbour

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

The history and development of the Nebraska State Museum since 1891 have been summarized in a preliminary manner up to 1925 in the first number of Volume I of the Bulletin of the Nebraska State Museum.1 Since 1927, the collections of the Nebraska State Museum, The University of Nebraska, have been housed in a new building, Morrill Hall, on the city campus of The University of Nebraska. It now seems fitting to report upon the exceptional progress of the past few years, and to acknowledge the fine cooperation of those who have helped to make it possible.

Spruce In The Western Miocene, George F. Beck Nov 1936

Spruce In The Western Miocene, George F. Beck

All Faculty Scholarship for the College of the Sciences

One of the real surprises in store for us as we began to section specimens of petrified wood from the Vantage and certain other horizons in Central Washington, was the prevalence of a spruce type hardly hinted at in the leaf lists as published for the various sediments of Yakima time (upper miocene?).

Palaeontologic And Geologic Consideration Of Early Man In Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1936

Palaeontologic And Geologic Consideration Of Early Man In Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

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

There has been much discussion recently relative to the geologic age of Yuma and Folsom artifacts. The writers submit the following palaeontological and geological data which may aid in a better interpretation of the subject. This paper deals with three localities in Nebraska where Yuma and Folsom implements have been found with extinct mammals; namely, the Scottsbluff Bison Quarry, the Sand Hill blow-out sites, and the Sioux County artifact sites.

Exotic Ancient Forests Of Washington, George F. Beck Apr 1935

Exotic Ancient Forests Of Washington, George F. Beck

All Faculty Scholarship for the College of the Sciences

The greatest fossil forest in the world is located within easy driving distance of the University of Washington campus in the State of Washington, near the Columbia River, east of the city of Ellensburg. Mr. George F. Beck, a member of the faculty of the Ellensburg State Normal School, and a former graduate student of the College of Forestry of the University of Washington, discovered this forest, which is now known as the Ginkgo Forest State Park. Aside from its importance from a scientific point of view, this "petrified forest," which contains a greater variety of species than any other …

A New Fossil Peccary, Prosthennops Niobrarensis, From Brown County, Nebraska, Edwin H. Colbert Jan 1935

A New Fossil Peccary, Prosthennops Niobrarensis, From Brown County, Nebraska, Edwin H. Colbert

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

During the summer of 1929, the writer, accompanied by Mr. Paul O. McGrew of the University of Nebraska, discovered during the course of excavations for fossil vertebrates in northern Brown County, Nebraska, a fairly complete peccary skull referable to the genus Prosthennops. This skull, due to its several unusual characters, as well as to its fair degree of completeness, would seem to warrant a special and a rather detailed description. Consequently the specimen has been kindly turned over to me by Dr. E. H. Barbour, Director of the Nebraska State Museum, not only for the purpose of the present …

A New Miocene Dog, Mesocyon Geringensis, Sp. Nov., Erwin Hinckley Barbour, C. Bertrand Schultz

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

A field party from the Nebraska State Museum consisting of Messrs. E. L. Blue, Frank Crabill, Loren Eiseley, and C. Bertrand Schultz, on August 28, 1931, was fortunate in finding the remains of a new Mesocyon. This specimen, number 4-28-8-31, the Nebraska State Museum, was found in the Gering formation (lower Miocene), fifteen feet above the Brule, 400 feet west of the road in Redington Gap, near the center of the S. 1/2, sec. 14, T. 19 N., R. 52 W., west of Bridgeport, Morrill County, Nebraska.

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 (1924–2023)

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

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

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 (1924–2023)

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 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 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 (1924–2023)

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 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 (1924–2023)

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 (1924–2023)

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.
