The Mandible Of Amebelodon Fricki, Erwin H. Barbour
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.

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 Morphology, Life History, And Control Of Some Common Species Of Oniscoidea Found In South Dakota, M. T. Fredricksen
The Morphology, Life History, And Control Of Some Common Species Of Oniscoidea Found In South Dakota, M. T. Fredricksen
Electronic Theses and Dissertations
Since practically no work has been done upon the life history and development of the common pill bugs or sow bugs, it is the aim of this paper to record the investigations of the life history and development as carried on by the author. The morphology was added in order to give the reader a definite idea of the organization and structure of these species.
A Systematic Treatise Of The Coccidae (Scale Insects) Of Brookings County, South Dakota, Merrill K. Riley
A Systematic Treatise Of The Coccidae (Scale Insects) Of Brookings County, South Dakota, Merrill K. Riley
Electronic Theses and Dissertations
It is the purpose of this paper to present in an introductory manner a systematic treatise of the scale insects of South Dakota, by making an intensive study of all species represented in Brookings County. It can be asserted that this paper is a complete treatise of all species present, but a thorough attempt was made to obtain specimens of all existing species. This treatise involves only the species now present, though at times other forms have been reported. Notes have been included giving the plants, location, and abundance.
The Mandibular Tusks Of Amebelodon Fricki, Erwin H. Barbour
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 …
