Pleistocene Fossils In Michigan
Throughout the State of Michigan in the United States, many people have found the remains of Pleistocene mammals, almost exclusively mammoths and mastodons. Most of these fossils are found by farmers or construction workers, but most are now in the collection of the University of Michigan. The finding of vertebrate fossils in Michigan is quite rare, so it is best to turn over any specimens to a university or museum for proper cleaning and documentation. Many of these mastodon fossils are found in Southern Michigan, mostly around Ann Arbor. Most mammoth sites are in Northern Michigan. Pleistocene mammals of Michigan *Jefferson Mammoths, '' Mammuthus jeffersoni'' This species of Mammoth has been found throughout Michigan, and is believed to have eaten mostly grass based on the characteristics of its teeth. These animals were much like the horse, chewing their food from side to side. Specimens of this animal have been found with marks on their bones from what is believed to have been ...

Elephant
Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are the only surviving members of the family Elephantidae and the order Proboscidea. The order was formerly much more diverse during the Pleistocene, but most species became extinct during the Late Pleistocene epoch. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs. Elepha ...

Pleistocene United States
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Berrien County, Michigan
Berrien County is a county on the south line of Michigan, at the southwestern corner of the state. As of the 2020 Census, the population was 154,316. The county seat is St. Joseph. Berrien County is included in the Niles-Benton Harbor, MI Metropolitan Statistical Area, which is also included in the South Bend- Elkhart- Mishawaka, IN-MI Combined Statistical Area. History As one of the Cabinet counties, Berrien County was named for John M. Berrien of Georgia, US Attorney General (1829–1831) under US President Andrew Jackson. The county was founded in 1829, and was organized in 1831, before Michigan was accepted into the Union as a state. When Michigan Territory was established in 1805, the area of present Berrien County was included in the boundary of Wayne County. About 1780, New Jersey resident William Burnett established a trading post at the mouth of the St. Joseph River (present-day site of St. Joseph) to serve indigenous peoples and French Canadian residen ...

Antler
Antlers are extensions of an animal's skull found in members of the Cervidae (deer) family. Antlers are a single structure composed of bone, cartilage, fibrous tissue, skin, nerves, and blood vessels. They are generally found only on males, with the exception of reindeer/caribou. Antlers are shed and regrown each year and function primarily as objects of sexual attraction and as weapons. In contrast to antlers, horns—found on pronghorns and bovids, such as sheep, goats, bison and cattle—are two-part structures that usually do not shed. A horn's interior of bone is covered by an exterior sheath made of keratin (the same material as human fingernails and toenails). Etymology Antler comes from the Old French ''antoillier '' (see present French : "Andouiller", from'' ant-, ''meaning before,'' oeil, ''meaning eye and'' -ier'', a suffix indicating an action or state of being) possibly from some form of an unattested Latin word ''*anteocularis'', "before the eye ...

Cervalces Scotti
''Cervalces scotti'', the elk moose or stag-moose, is an extinct species of large deer that lived in North America during the Late Pleistocene epoch. It had palmate antlers that were more complex than those of a moose and a muzzle more closely resembling that of a typical deer. It is the only known North American member of the genus ''Cervalces''. Description It was as large as the moose, with an elk-like head, long legs, and palmate antlers that were more complex and heavily branching than the moose. ''Cervalces scotti'' reached in length and a weight of . The stag-moose resided in North America during an era with other megafauna such as the woolly mammoth, ground sloth, long horn bison, and saber toothed cat."Cervalces Scotti." Maxilla & Mandible. N.p., n.d. Web. 23 Oct. 2014. . The species became extinct approximately 11,500 years ago, toward the end of the most recent ice age, as part of a mass extinction of large North American mammals.

Skull
The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone. However two parts are more prominent: the cranium and the mandible. In humans, these two parts are the neurocranium and the viscerocranium ( facial skeleton) that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In humans these sensory structures are part of the facial skeleton. Functions of the skull include protection of the brain, fixing the distance between the eyes to allow stereoscopic vision, and fixing the position of the ears to enable sound localisation of the direction and distance of sounds. In some animals, such as horned ungulates (mammals with hooves), the skull also has a defensive function by providing the mount (on the ...

Castoroides Ohioensis
''Castoroides'' (Latin: "beaver" (castor), "like" (oides)), or giant beaver, is an extinct genus of enormous, bear-sized beavers that lived in North America during the Pleistocene. Two species are currently recognized, ''C. dilophidus'' in the Southeastern US and ''C. ohioensis'' in the rest of its range. ''C. leiseyorum'' was previously described from the Irvingtonian of Florida, but is now regarded as an invalid name. All specimens previously described as ''C. leiseyorum'' are considered to belong to ''C. dilophidus''. Description Species of ''Castoroides'' were much larger than modern beavers. Their average length was approximately , and they could grow as large as . The weight of the giant beaver could vary from to . This makes it the largest known rodent in North America during the Pleistocene and the largest known beaver. Recent analyses suggest that they weighed less, closer to , but this is disputable. The hind feet of the giant beaver were much larger than in modern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammut Americanum
A mastodon ( 'breast' + 'tooth') is any proboscidean belonging to the extinct genus ''Mammut'' (family Mammutidae). Mastodons inhabited North and Central America during the late Miocene or late Pliocene up to their extinction at the end of the Pleistocene 10,000 to 11,000 years ago. They lived in herds and were predominantly forest-dwelling animals. They generally had a browsing diet, distinct from that of the contemporary Columbian mammoth, which tended towards grazing. ''M. americanum'', the American mastodon, and ''M. pacificus'', the Pacific mastodon, are the youngest and best-known species of the genus. Mastodons disappeared from North America as part of a mass extinction of most of the Pleistocene megafauna, widely believed to have been caused by a combination of climate changes at the end of the Pleistocene and overexploitation by Paleo-Indians. History A Dutch tenant farmer found the first recorded remnant of ''Mammut'', a tooth some in weight, in the village of Cl ...
