Camels Of The Columbia Plateau, George F. Beck Mar 1937

Camels Of The Columbia Plateau, George F. Beck

All Faculty Scholarship for the College of the Sciences

However foreign they may seem to us the camels are one of our oldest American stocks. Our Western plains once supported large herds of them, humped and humpless, large and small, giraffe-necked and normal-necked. For some 35 million years, from Oligocene to the Pliocene, the camels were confined to North America and it was not until recently, geologically speaking that we shared the race with the Old World.

Determination Of Fossil Woods (Part Ii-The Oaks), George F. Beck Feb 1937

Determination Of Fossil Woods (Part Ii-The Oaks), George F. Beck

All Faculty Scholarship for the College of the Sciences

The oaks, unlike the sacred ginkgo or temple tree, are thriving throughout the northern hemisphere today. Not only is the oak an entirely familiar and abundant element in existing landscapes, but its history goes back into the centuries and ages. Its leaves and woods are generously represented in fossil forests as far back as the early Tertiary and closely allied forms penetrate as far back as the Cretaceous.

Wood Occurring In The Ginkgo And Associated Petrified Forest (No. 1-The Gingko), George F. Beck Dec 1936

Wood Occurring In The Ginkgo And Associated Petrified Forest (No. 1-The Gingko), George F. Beck

All Faculty Scholarship for the College of the Sciences

The most interesting single fossil tree, but at the same time the most difficult to determine in the Ginkgo Petrified Forest (Washington), is the tree after which this unusual petrified forest takes its name. The ginkgo is not only the world's oldest and most remarkable living tree, but it has long been regarded as holding the most striking fossil record of any living thing, plant or animal.

Grinding Thin Sections For Determining Petrified Woods, George F. Beck Dec 1936

Grinding Thin Sections For Determining Petrified Woods, George F. Beck

All Faculty Scholarship for the College of the Sciences

The collector and student of petrified woods cannot long be satisfied to merely place these colorful and interesting specimens in the cabinet with the mere label, "petrified wood." Frequently determining the types of wood which once thrived in a given area is of importance to give a clue to climatic conditions of past geological ages. The collector should at least be qualified to recognize the more common woods and distinguish one family of trees from another.

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.

Fossil Bearing Basalts (More Particularly The Yakima Basalt Of Central Washington), George F. Beck Nov 1935

Fossil Bearing Basalts (More Particularly The Yakima Basalt Of Central Washington), George F. Beck

All Faculty Scholarship for the College of the Sciences

Such an overwhelming majority of the floral and faunal remains of the earth's crust have been yielded by rocks of sedimentary origin that generalized statements concerning the occurrence of fossils often neglect their more rare appearance in metamorphic and igneous rocks. In fact there is the temptation, after volcanic tuffs have been excluded as more or less sedimentary, to venture the positive assertion that by their very character igneous rocks are incapable of recording the presence of the life which may have existed at the time of their extrusion. As a result, most that has been written concerning fossil floras …

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 Jan 1935

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.

Gnathabelodon Thorpei, Gen. Et Sp. Nov. A New Mud-Grubbing Mastodon, Erwin Hinckley Barbour, George F. Sternberg

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

In February, 1932, while opening a gravel pit to get material for highway construction, the skull, tusks, and mandible of a new longirostral mastodont were found by Robert Arnold on his ranch, Sec. 24, T. 12 S., R. 22 W., 1 1/2 miles due east of Ogallah, Trego County, western Kansas. This point is located about 20 miles west and three miles north of Hays, the seat of the Fort Hays Kansas State College, in the museum of which the above mentioned specimen is mounted and exhibited. When unexpectedly exposed by Mr. Arnold and his associates, the great skull was …

Arrowhead Making In The Ginkgo Petrified Forest, George F. Beck Dec 1934

Arrowhead Making In The Ginkgo Petrified Forest, George F. Beck

All Faculty Scholarship for the College of the Sciences

In a sense we must give the Indians credit for being the original discoverers of these fossil forests of Central Washington. Not that I have been able to run down any legends or traditions regarding fossil logs or any certainty that the Indians recognized them as trees in stone. My opinion is that they could not have failed to recognize them as trees. Be that as it may, they long ago took recognition of the fact that certain logs were to be prized as the source of flint for their arrow-heads.

Hampton Tusk Of Mastodon, Emmett J. Cable Oct 1934

Hampton Tusk Of Mastodon, Emmett J. Cable

Mastodon Tusk Background Material

On September 23, last, there was unearthed a large tusk in a gravel pit on the farm of W. S. Heuermann, section 21, Reeve township, Franklin County, about four miles south of the town of Hampton, Iowa. While loading gravel, one of the workmen noticed something sticking out of the gravels that resembled a horn. Upon closer examination it was found to be a giant tusk, the largest of its kind, according to the best information available, ever found. The tusk was complete before it was broken by the workmen. The length was 11 feet, 7½ inches, while the circumference, …

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 May 1934

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. …
