  • Geology of Part of the Townsend Valley Broadwater and Jefferson
    Geology of Part of the Townsend Valley Broadwater and Jefferson » Counties,x Montana GEOLOGICAL SURVEY BULLETIN 1042-N CONTRIBUTIONS TO ECONOMIC GEOLOGY GEOLOGY OF PART OF THE TOWNSEND VALLEY BROADWATER AND JEFFERSON COUNTIES, MONTANA By V. L. FREEMAN, E. T. RUPPEL, and M. R. KLEPPER ABSTRACT The Townsend Valley, a broad intermontane basin in west-central Montana, extends from Toston to Canyon Ferry. The area described in this report includes that part of the valley west of longitude 111° 30' W. and south of latitude 46° 30' N. and the low hills west and south of the valley. The Missouri River enters the area near Townsend and flows northward through the northern half of the area. Three perennial tributaries and a number of intermittent streams flow across the area and into the river from the west. The hilly parts of the area are underlain mainly by folded sedimentary rocks ranging in age from Precambrian to Cretaceous. The broad pediment in the southwestern part is underlain mainly by folded andesitic volcanic rocks of Upper Cretaceous age and a relatively thin sequence of gently deformed tuffaceous rocks of Tertiary age. The remainder of the area is underlain by a thick sequence of Tertiary tuffaceous rocks that is partly blanketed by late Tertiary and Quater­ nary unconsolidated deposits. Two units of Precambrian age, 13 of Paleozoic age, 7 of Mesozoic age, and several of Cenozoic tuffaceous rock and gravel were mapped. Rocks of the Belt series of Precambrian age comprise a thick sequence of silt- stone, sandstone, shale, and subordinate limestone divisible into the Greyson shale, the Spokane shale, and the basal part of the Empire shale, which was mapped with the underlying Spokane shale.

  • Unit-V Evolution of Horse
    UNIT-V EVOLUTION OF HORSE Horses (Equus) are odd-toed hooped mammals belong- ing to the order Perissodactyla. Horse evolution is a straight line evolution and is a suitable example for orthogenesis. It started from Eocene period. The entire evolutionary sequence of horse history is recorded in North America. " Place of Origin The place of origin of horse is North America. From here, horses migrated to Europe and Asia. By the end of Pleis- tocene period, horses became extinct in the motherland (N. America). The horses now living in N. America are the de- scendants of migrants from other continents. Time of Origin The horse evolution started some 58 million years ago, m the beginning of Eocene period of Coenozoic era. The modem horse Equus originated in Pleistocene period about 2 million years ago. Evolutionary Trends The fossils of horses that lived in different periods, show that the body parts exhibited progressive changes towards a particular direction. These directional changes are called evo- lutionary trends. The evolutionary trends of horse evolution are summarized below: 1. Increase in size. 2. Increase in the length of limbs. 3. Increase in the length of the neck. 4. Increase in the length of preorbital region (face). 5. Increase in the length and size of III digit. 6. Increase in the size and complexity of brain. 7. Molarization of premolars. Olfactory bulb Hyracotherium Mesohippus Equus Fig.: Evolution of brain in horse. 8. Development of high crowns in premolars and molars. 9. Change of plantigrade gait to unguligrade gait. 10. Formation of diastema. 11. Disappearance of lateral digits.

  • Skeleton of the Oligocene (30 Million-Year-Old) Horse, Mesohippus, Is a Featured Exhibit at the New North Dakota Cowboy Hall of Fame in Medora
    Skeleton of the Oligocene (30 million-year-old) horse, Mesohippus, is a featured exhibit at the new North Dakota Cowboy Hall of Fame in Medora By John W. Hoganson Developers of the recently opened North Dakota Cowboy Hall of Fame contacted me about having a fossil exhibit in the new Hall in Medora. Of course, what would be more appropriate than an exhibit interpreting the evolution of the horse? Most people are under the false impression that horses did not inhabit North America until they were introduced by the Spaniards during the early days of conquest. But horses are indigenous to North America. Fossil remains of the earliest horse, referred to as Hyracotherium (or sometimes Eohippus), have been recovered from early Eocene (about 50 million years old) rocks in North America. In fact, they were some of the most abundant mammals that lived during that time. The fossil record of horses in North Dakota extends back to the Oligocene, about 30 million years ago, when the diminutive horse, Mesohippus roamed western North Dakota. Mesohippus was tiny, about the size of a sheep. The adults were only about 20 inches tall at the shoulder. They also had three toes on each foot compared to the modern horse Equus that has one. Mesohippus was also probably more of a browsing herbivore compared to the modern grazing horse. We have found many Mesohippus fossils in North Dakota but no complete skeletons. Consequently, the Mesohippus skeleton on exhibit at the Cowboy Hall of Fame is an exact cast replica. We have also found the remains of 50,000-year-old horses in North Dakota indicating that horses lived here during the last Ice Age.

Both series were founded by Dr. Bryant Walker, Mr. Bradshaw H. Swales, and Dr. W. W. Newcomb. Occasionally the Museum publishes contributions outside of these series. Beginning in 1990 these are titled Special Publications and Circulars and each is sequentially numbered. All submitted manuscripts to any of the Museum’s publications receive external peer review. The Occasional Papers, begun in 1913, serve as a medium for original studies based principally upon the collections in the Museum. They are issued separately. When a sufficient number of pages has been printed to make a volume, a title page, table of contents, and an index are supplied to libraries and individuals on the mailing list for the series. The Miscellaneous Publications, initiated in 1916, include monographic studies, papers on field and museum techniques, and other contributions not within the scope of the Occasional Papers, and are published separately. Each number has a title page and, when necessary, a table of contents. A complete list of publications on Mammals, Birds, Reptiles and Amphibians, Fishes, I nsects, Mollusks, and other topics is available.

This species can cope with variations in substrate, especially in ice and snow environment. However, few detailed studies about reindeer hoof are available. Thus this article describes the results of studies on macro- and micro-structures of reindeer hoof. Material and Methods: The gross anatomy of the reindeer hooves was examined. Stereo microscope (SM) and a scanning electron microscope (SEM) were used to observe four key selected positions of reindeer hooves. Moreover, element contents of the three selected positions of reindeer hooves were analysed using the SEM equipped with energy dispersive spectroscope. Results: Hoof bone structures were similar to other artiodactyl animals. In the microscopic analysis, the surfaces of the ungula sphere and ungula sole presented irregular laminated structure. Ungula edge surfaces were smooth and ungula cusp surfaces had unique features. Aside from C, O, and N, reindeer hooves contained such elements as S, Si, Fe, Al, and Ca. The content of the elements in different parts varied. Ti was the particular element in the ungula sole, and ungula edge lacked Mg and S which other parts contained.

  • The European Fallow Deer (Dama Dama Dama)
    Heredity (2017) 119, 16–26 OPEN Official journal of the Genetics Society www.nature.com/hdy ORIGINAL ARTICLE Strong population structure in a species manipulated by humans since the Neolithic: the European fallow deer (Dama dama dama) KH Baker1, HWI Gray1, V Ramovs1, D Mertzanidou2,ÇAkın Pekşen3,4, CC Bilgin3, N Sykes5 and AR Hoelzel1 Species that have been translocated and otherwise manipulated by humans may show patterns of population structure that reflect those interactions. At the same time, natural processes shape populations, including behavioural characteristics like dispersal potential and breeding system. In Europe, a key factor is the geography and history of climate change through the Pleistocene. During glacial maxima throughout that period, species in Europe with temperate distributions were forced south, becoming distributed among the isolated peninsulas represented by Anatolia, Italy and Iberia. Understanding modern patterns of diversity depends on understanding these historical population dynamics. Traditionally, European fallow deer (Dama dama dama) are thought to have been restricted to refugia in Anatolia and possibly Sicily and the Balkans. However, the distribution of this species was also greatly influenced by human-mediated translocations. We focus on fallow deer to better understand the relative influence of these natural and anthropogenic processes. We compared modern fallow deer putative populations across a broad geographic range using microsatellite and mitochondrial DNA loci. The results revealed highly insular populations, depauperate of genetic variation and significantly differentiated from each other. This is consistent with the expectations of drift acting on populations founded by small numbers of individuals, and reflects known founder populations in the north.
