  • 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.

  • 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.

With all fixtures locked down, one cricket fan lets his mind wander to what might have been. Vasant Raji, India’s oldest first-class cricketer, passed away recently. He was 100 years old.

EARLY PLIOCENE (LATEST HEMPHILLIAN) HORSES FROM THE YEPÓMERA LOCAL FAUNA, CHIHUAHUA, MEXICO Bruce J. MacFadden* ABSTRACT The latest Hemphillian (Hh4) is characterized by a distinctive equid assemblage, four spe- cies of which are widespread in North America. One of the largest collections of Hh4 equids is from Yepómera, located in Chihuahua, Mexico. Although Yepómera is actually a series of sub-localities, the equids are morphologically similar from each of these and therefore can be considered as a local faunal assemblage of four sympatric species. The distinctive dental patterns, size of the cheek teeth, and (in most cases) metapodial dimensions, make these horses readily distinguishable in the field. Yepómera equids include the monodactyl Astrohippus stockii and Dinohippus mexicanus, and tridactyl Neohipparion eurystyle and Nannippus aztecus. Yepómera is the type locality for the species A. stockii and D. mexica- nus, both described by Lance in 1950. Neohipparion eurystyle and the genus Neohipparion and A. stockii and the genus Astrohippus become extinct at the end of Hh4. Nannippus aztecus is a sister taxon of later Nannippus and D. mexicanus is the sister taxon of Equus, the equid genera that survived in North America during the Plio-Pleistocene. With hypsodonty indices between 2.6 and 3.7, all of the Yepómera horse species have high-crowned teeth, traditionally interpreted as a grazing adaptation.

    Florida Fossil Horse Newsletter Volume 2 Number 3 3rd Quarter--September 1993 What's Inside? Fossil Skeletons and Mother Lodes George Gaylord Simpson Mammal Tooth Structure Horse Phylogeny Member Profile Book Review Idaho State Fossil Fossil Skeletons and Mother Lodes For those who have collected old bones and teeth from Florida, you can attest to the fact that although fossil mammals are indeed plentiful, they are usually found disarticulated; the skeletons are almost never found in tact. Localities throughout the world that do preserve complete skeletons are indeed rare and these have been called Lagerstätten, a German term roughly meaning "mother lode." Steve Gould once noted that ".Lagerstätten are rare, but their contributions to our knowledge of life's history is disproportionate to their frequency." Why is this so? For invertebrates, soft- bodied organisms may be preserved thus giving insight into various fossil groups not normally fossilized (see Book Review below). For vertebrates the same can be true. At the fabulous Eocene Messel in Germany, carbonized impressions of stomach contents of palaeotheres (close relatives of horses, see chart on page 6) indicate that they were eating grapes, and that bats were eating butterflies. For other Lagerstätten containing vertebrates, the Scientific value is in the completeness of the skeleton. These entire specimens allow paleontologists to decipher the anatomy and biology of these extinct organisms. The western U. S. has several examples of extraordinary localities with complete fossil skeletons that can be considered Lagerstätten. During our trip out west on our way to Salt Lake City, we had the opportunity to visit some of these truly extraordinary fossil sites.

  • Evolution of Horse
    EVOLUTION OF HORSE Horses are one of the oldest forms of mammals. Evolution of horse dates back to Eocene epoch, more million than 50 million years ago. Primary centre of evolution were Great Plains of North America, from where species migrated to Europe and Asia from time to time. Horses became extinct in North America by the end of Pleistocene epoch but their offshoots in Europe and Asia flourished. Evolution of horse was triggered by a change in the climate and vegetation during lower coenozoic period, when grasslands in most parts of the world replaced forests. The main modifications in the body of horses can be outlined as follows: · 1. Increase in the size and height of the body from a small, rabbit-like animal to 6 feet tall grassland animal. 2. Gradual enlargement and better development of the third digit (median digit) and reduction of the other lateral digits. 3. Lengthening of the limbs and perfection of the hoof for fast running in open grasslands. 4. Reduction of ulna bone in the fore leg and fibula in the hind leg and strengthening of radius and tibia. 5. Change from digitigrade to unguligrade locomotion for fast running. 6. Elongation of the preorbital or facial region of the skull and migration of eyes to the top of head. 7. Modification of teeth from brachydont (low-crowned) to hypsodont (high crowned) to withstand tougher food (grass). 8. Increase in the size and complexity of the brain for superior intelligence. 9. Reduction in pectoral girdle and disappearance of the weak clavicle. 10. Body became streamlined, muscles tight, without loose fat, for long and sustained running.

This unique series combines aspects of the expanding study of sport in the global society, providing comprehensiveness and comparison under one editorial umbrella. It is particularly timely, with studies in the political, cultural, anthropological, ethnographic, social, economic, geographical and aesthetic elements of sport proliferating in institutions of higher education. Eric Hobsbawm once called sport one of the most significant practices of the late nineteenth century. Its significance was even more marked in the late twentieth century and will continue to grow in importance into the new millennium as the world develops into a ‘global village’ sharing the English language, technology and sport.
