THE SCOTTSBLUFF BISON QUARRY AND ITS ARTIFACTS

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

A NEW OREODONT SLAB

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 is somewhat obscured in the pelvic region by the overlying hind quarters of the young animal. The left foreleg is hidden by the skull. The sternal ribs, as well as the ribs, are in place. The bones are firm, and of ivory whiteness, and show up well against the brownish sandstone. This fine specimen was found in the Gering formation (Lower Miocene) near Birdcage Gap, Morrill County, Nebraska, by the field parties operating there in September 1931, and was dug out later by Mr. and Mrs. C. Bertrand Schultz, students in the University of Nebraska, and assistants in the museum. By them it was later prepared for exhibition

PALAEONTOLOGIC AND GEOLOGIC CONSIDERATION OF EARLY MAN IN NEBRASKA

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

THE MOUNTED SKELETON OF BISON OCCIDENTALIS, AND ASSOCIATED DART-POINTS

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

\u3ci\u3eParabos dodsoni\u3c/i\u3e Barbour and Schultz: A Correction

A Bos-like animal, Parabos dodsoni, was recently described by Barbour and Schultz (1941, A New Fossil Bovid from Nebraska , Bull. Univ. Nebr. State Museum, Vol. II, No. 7, pp. 63-66, Figs. 24-27, December) as a new genus and species from the Pleistocene of Nebraska. Attention has been called to the writers by Dr. E. H. Colbert of the American Museum of Natural History that the name Parabos is preoccupied. Parabos was introduced as a generic name by C. Arambourg and J. Piveteau (1929, Note preliminaire sur un Ruminant du Pliocene inferieur du Roussillon, C. R. Bull. Soc. Geol. de France, 4th Ser., XXIX, pp. 144-146). Unfortunately the reference was missed by the present writers as well as by the editors of the Zoological Record (1929-1939). The writers propose the name Platycerabos to replace Parabos for the new American bovid. The corrected designation would thus be Platycerabos dodsoni (Barbour and Schultz). The occurrence of a Bos-like form from the Pleistocene of North America is unique. It has long been thought that the migration of true bovines from Asia to North America during the Pleistocene was limited to Bison, but the discovery of Platycerabos dodsoni has altered this belief

A NEW GIANT CAMEL, TITANOTYLOPUS NEBRASKENSIS, gen. et sp. nov.

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\u27s 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 name Titanotylopus nebraskensis. The teeth are very brachyodont, and the incisors are not spatulate. The dental formula of T-itanotylopus nebraskensis reads as follows: i 3, c 1, p 2, m 3. The third incisor was practically aborted as indicated by the small and very shallow alveolus crowded close to the base of the canine. The first left incisor has the enamel preserved on the inner side. It measures but 19 mm. in height. It should be noted that in Pliauchenia the cheek teeth are subbrachyodont to hypsodont; in M egatylopus they are more or less hypsodont; and in Titanotylopus they are distinctly brachyodont. Obviously premolars 1 and 2 have long been missing in this genus for not a vestige of them has been left. Such an assemblage of characters seems well beyond the realm of mere variation, and we find no ready escape from making this a new genus. So few genera of camels are reported as yet from the Pleistocene that Titanotylopus deserves the more attention. This unusual specimen was secured during the first week in September, 1933, by Frank Crabill (Class of 1935), a member of the Morrill Palaeontological Expedition of 1933, but was found, collected, and donated by Mr. and Mrs. S. E. Jensen of Red Cloud who found it in a small pit about eight miles northwest of Red Cloud, Webster County, Nebraska. The exact location of this pit is the N.W.1,4, Sec. 17, T. 2 N., R. 11 W. The jaw was found 33 feet below the surface in Pleistocene gravel of supposed Kansan age, and is accessioned 1-6-9-33, the Nebraska State Museum. The specimen consists of the right ramus of the mandible together with the symphysis intact, the dentition being complete but damaged by exposure

THE NEBRASKA METEOR AND METEORITE OF AUGUST 8, 1933

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

A New Giant Camel \u3ci\u3eGIGANTOCAMELUS FRICKI\u3c/i\u3e, gen. et sp. nov.

A lower Pleistocene deposit containing fossil vertebrates near Broadwater, Morrill county, Nebraska, has been reported upon by the writers, beginning three years ago. Five fossil quarries have been opened since the site was discovered in 1936

Palaeogene glendonites from Denmark

Pristinely preserved mineral pseudomorphs called glendonites, up to 1.6 m long, from the Palaeogene strata of Denmark allow detailed crystallographic characterisation and add to the understanding of the transformation of the precursor mineral, ikaite (CaCO3 center dot 6H(2)O), to calcite, which constitutes the glendonite. We describe Danish pseudomorphs after ikaite from two localities and formations: the Early Eocene Fur Formation and the Late Oligocene Brejning Formation. This detailed study highlights that key aspects such as morphology and mode of occurrence of these ancient glendonites are identical to those of their parent mineral ikaite, when it grows in marine sediments. Systematic distortion of the angles in glendonite and marine sedimentary ikaite relative to the ideal ikaite symmetry may arise due to the incorporation of organic matter into the crystal structure, and we demonstrate the similarity between modern and ancient ikaite formation zones in the marine sedimentary realm with respect to organic matter
