South Dakota to Nebraska
Geological Society of America Special Paper 325 1998 Lithostratigraphic revision and correlation of the lower part of the White River Group: South Dakota to Nebraska Dennis O. Terry, Jr. Department of Geology, University of Nebraska—Lincoln, Lincoln, Nebraska 68588-0340 ABSTRACT Lithologic correlations between type areas of the White River Group in Nebraska and South Dakota have resulted in a revised lithostratigraphy for the lower part of the White River Group. The following pedostratigraphic and lithostratigraphic units, from oldest to youngest, are newly recognized in northwestern Nebraska and can be correlated with units in the Big Badlands of South Dakota: the Yellow Mounds Pale- osol Equivalent, Interior and Weta Paleosol Equivalents, Chamberlain Pass Forma- tion, and Peanut Peak Member of the Chadron Formation. The term “Interior Paleosol Complex,” used for the brightly colored zone at the base of the White River Group in northwestern Nebraska, is abandoned in favor of a two-part division. The lower part is related to the Yellow Mounds Paleosol Series of South Dakota and rep- resents the pedogenically modified Cretaceous Pierre Shale. The upper part is com- posed of the unconformably overlying, pedogenically modified overbank mudstone facies of the Chamberlain Pass Formation (which contains the Interior and Weta Paleosol Series in South Dakota). Greenish-white channel sandstones at the base of the Chadron Formation in Nebraska (previously correlated to the Ahearn Member of the Chadron Formation in South Dakota) herein are correlated to the channel sand- stone facies of the Chamberlain Pass Formation in South Dakota. The Chamberlain Pass Formation is unconformably overlain by the Chadron Formation in South Dakota and Nebraska. -

It was becoming more arid, the tropical forests were disappearing from the northern latitudes, and there was an increase in seasonality. Research of the Chadronian (37- 33.7mya) in the Great Plains region of North America has documented the persistence of several mammalian taxa (e.g. primates) that are extinct in other parts of North America. -
Rodents (Mammalia) from the Pilgrim Creek Local Fauna, Wyoming: a Mixed Eocene and Oligocene Assemblage (Duchesnean to Whitneyan)

Korth Rochester Institute of Vertebrate Paleontology, 265 Carling Road, Rochester, New York 14610 <[email protected]> ABSTRACT Previously, only the non-eomyid rodents from the Pilgrim Creek fauna of Wyoming have been described (Sutton and Black, 1975; Korth, 1981; Korth and Emry, 2013). This fauna has been considered as Chadronian in age since its first description. Twenty-seven species of rodents are recognized here from this fauna. There is a predominance of Chadronian species (13 taxa); however, the presence of three species known elsewhere from the Duchesnean (“Leptotomus” guildayi, Metanoiamys korthi, Griphomys cf. alecer), four from the Orellan (“Prosciurus” sp., cf. relictus, Eumys elegans, “Scottimus” viduus, Protosciurus sp., cf. P. mengi), and two from the Whitneyan (Leptodontomys douglassi, Ansomys sp., cf. A. cyanotephrus,) demonstrates that the fauna is clearly mixed with elements from four different horizons. INTRODUCTION either earlier or later horizons, demonstrating the evident mixing of faunas. Over 40 years ago, Sutton and Black (1975) _________________________________________ identified 11 species of rodents from the Pilgrim Creek fauna of Wyoming (Table 1). However, TABLE 1. Previously identified rodents from the Pilgrim Creek specimens of the family Eomyidae were not local fauna, Wyoming (Sutton and Black, 1975). described or listed. The locality from which the Ischyromyidae fossils were collected is in the Teton National Forest Ischyromys cf. veterior in Jackson County, Wyoming along Pilgrim Creek Cylindrodontidae (Sutton and Black, 1975). -

Hoganson, J.W., 2009. Corridor of Time Prehistoric Life of North
Corridor of Time Prehistoric Life of North Dakota Exhibit at the North Dakota Heritage Center Completed by John W. Hoganson Introduction In 1989, legislation was passed that directed the North Dakota and a laboratory specialist, a laboratory for preparation of Geological Survey to establish a public repository for North fossils, and a fossil storage area. The NDGS paleontology staff, Dakota fossils. Shortly thereafter, the Geological Survey signed now housed at the Heritage Center, consists of John Hoganson, a Memorandum of Agreement with the State Historical Society State Paleontologist, and paleontologists Jeff Person and Becky of North Dakota which provided space in the North Dakota Gould. This arrangement has allowed the Geological Survey, in Heritage Center for development of this North Dakota State collaboration with the State Historical Society of North Dakota, Fossil Collection, including offices for the curator of the collection to create prehistoric life of North Dakota exhibits at the Heritage Center and displays of North Dakota fossils at over 20 other museums and interpretive centers around the state. The first of the Heritage Center prehistoric life exhibits was the restoration of the Highgate Mastodon skeleton in the First People exhibit area (fig. 1). Mastodons were huge, elephant- like mammals that roamed North America at the end of the last Ice Age about 11,000 years ago. This exhibit was completed in 1992 and was the first restored skeleton of a prehistoric animal ever displayed in North Dakota. The mastodon exhibit was, and still is, a major attraction in the Heritage Center. Because of its popularity, it was decided that additional prehistoric life displays should be included in the Heritage Center exhibit plans. -

They first inhabited Mongolia then spread into Eurasia and North America, while in North America they preferred flood plains and woodlands.

The New Adaption Gallery
Introduction In 1991, a group of Heritage Center staff began meeting informally after work to discuss a Heritage Center expansion. This “committee” was formalized in 1992 by Jim Sperry, Superintendent of the State Historical Society of North Dakota, and became known as the Space Planning About Center Expansion (SPACE) committee. The committee consisted of several Historical Society staff and John Hoganson representing the North Dakota Geological Survey. Ultimately, some of the SPACE committee ideas were rejected primarily because of anticipated high cost such as a planetarium, arboretum, and day care center but many of the ideas have become reality in the new Heritage Center expansion. In 2009, the state legislature appropriated $40 million for a $52 million Heritage Center expansion. The State Historical Society of North Dakota Foundation was given the task to raise the difference. On November 23, 2010 groundbreaking for the expansion took place. Planning for three new galleries began in earnest: the Governor’s Gallery (for large, temporary, travelling exhibits), Innovation Gallery: Early Peoples, and Adaptation Gallery: Geologic Time.

Paludicola 8(2):75-90 March 2011 © by the Rochester Institute of Vertebrate Paleontology RODENTS FROM THE CHADRONIAN (LATEST EOCENE) MEDICINE POLE HILLS LOCAL FAUNA, NORTH DAKOTA. PART 1. EUTYPOMYIDAE, CYLINDRODONTIDAE AND PIPESTONEOMYS Allen J. Kihm Department of Geosciences, Minot State University, 500 University Ave W, Minot, ND 58707 <[email protected]> ABSTRACT The Medicine Pole Hills local fauna is a large Chadronian fauna composed of more than 4600 mammal specimens, mostly isolated teeth, derived from a limited sequence of mudball conglomerates and sandstones. The producing layer probably represents an early stage of deposition of the Chadron Formation in North Dakota, but it may not be related to any of the named members of the formation. The material described includes Eutypomys parvus, Cylindrodon collinus, Pseudocylindrodon neglectus, Ardynomys saskatchewensis and Pipestoneomys sp. The samples of E. parvus and A. saskatchewensis include teeth not previously described for these taxa. The assemblage has the greatest commonality to the middle Chadronian Calf Creek local fauna of southern Saskatchewan. This similarity does not necessarily indicate a middle Chadronian age for the Medicine Pole Hills local fauna. The lack of late early Chadronian localities with large samples of rodents may exaggerate the apparent differences between these faunas and the Medicine Pole Hills sample. The Calf Creek and Medicine Pole Hills local faunas may represent an intermediate stage between the McCarty’s Mountain and Pipestone Springs faunas of Montana. The Medicine Pole Hills fauna may be somewhat older than the Calf Creek local fauna based on the occurrence of Leptomeryx yoderi. INTRODUCTION (Murphy et al., 1993), but continuing studies of the geology, particularly the heavy minerals, suggest this This is the third in a series of papers that describe correlation is poorly supported (Webster and Kihm, the mammals of the Medicine Pole Hills local fauna of 2009).
