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] |

Eucastor
''Eucastor'' is an extinct genus (biology), genus of beaver-grouped rodents. Based on the available evidence of the Foramen, foramina, ''Eucastor'' most likely is closely related to Beaver, ''Castor'', but not in its direct lineage.

Midwestern United States
The Midwestern United States, also referred to as the Midwest or the American Midwest, is one of four census regions of the United States Census Bureau (also known as "Region 2"). It occupies the northern central part of the United States. It was officially named the North Central Region by the Census Bureau until 1984. It is between the Northeastern United States and the Western United States, with Canada to the north and the Southern United States to the south. The Census Bureau's definition consists of 12 states in the north central United States: Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin. The region generally lies on the broad Interior Plain between the states occupying the Appalachian Mountain range and the states occupying the Rocky Mountain range. Major rivers in the region include, from east to west, the Ohio River, the Upper Mississippi River, and the Missouri River. ...

Giant Pleistocene Beaver, Castoroides Ohioensis
In folklore, giants (from Ancient Greek: '' gigas'', cognate giga-) are beings of human-like appearance, but are at times prodigious in size and strength or bear an otherwise notable appearance. The word ''giant'' is first attested in 1297 from Robert of Gloucester's chronicle. It is derived from the ''Gigantes'' ( grc-gre, Γίγαντες) of Greek mythology. Fairy tales such as '' Jack the Giant Killer'' have formed the modern perception of giants as dimwitted ogres, sometimes said to eat humans, while other giants tend to eat the livestock. The antagonist in ''Jack and the Beanstalk'' is often described as a giant. In some more recent portrayals, like those of Jonathan Swift and Roald Dahl, some giants are both intelligent and friendly. Literary and cultural analysis Giants appear in the folklore of cultures worldwide as they represent a relatively simple concept. Representing the human body enlarged to the point of being monstrous, giants evoke terror and remind human ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wyandot County, Ohio
Wyandot County is a county located in the northwestern part of the U.S. state of Ohio. As of the 2020 census, the population was 21,900. Its county seat is Upper Sandusky. It was named for the Wyandot Indians, who lived here before and after European encounter. Their autonym is variously translated from their language as "around the plains" and "dwellers on the peninsula". The county was organized by the state legislature from parts of Crawford, Marion, Hardin and Hancock counties on February 3, 1845. History Geography According to the U.S. Census Bureau, the county has a total area of , of which is land and (0.2%) is water. Adjacent counties * Seneca County (north) * Crawford County (east) * Marion County (south) * Hardin County (southwest) * Hancock County (northwest) Demographics 2000 census As of the census of 2000, there were 22,908 people, 8,882 households, and 6,270 families living in the county.

Sheriden Cave
Sheridan Cave is a Paleo-Indian archaeological site from the late Ice age in Wyandot County, Ohio. Glacial deposits sealed off the cave more than 10,000 years ago. Sheriden Cave is a karst sinkhole on a dolomite ridge that crosses Hancock and Wyandot Counties. It is associated with the Indian Trail Caverns that opened in 1927. Sheriden Cave was discovered in 1989. The cave is unique because in addition to stone tools, there were also bone tools, remains of extinct animals, and organic matter found in the cave. Radiocarbon dating of artifacts indicate that they were used 11,000 and 12,000 years ago. Excavation By 1995, the opening to the cave was exposed by a bulldozer. There was an initial study of the site due to the paleontological remains, but a 1995 discovery found evidence of human occupation of the cave. Kenneth Tankersley of Kent State University led the excavation of the site, with his colleagues and the support of the National Science Foundation, beginning about 1997 an ...

Stag Moose
''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.

Arctodus
''Arctodus'' is an extinct genus of short-faced bear that inhabited North America during the Pleistocene (~2.5 Mya until 12,000 years ago). There are two recognized species: the lesser short-faced bear (''Arctodus pristinus'') and the giant short-faced bear (''Arctodus simus''). Both species are relatively rare in the fossil record- ''A. pristinus'' was largely restricted to the Early Pleistocene of the eastern United States, whereas ''A. simus'' had a cosmopolitan range, with most finds being from the Late Pleistocene of the US, Mexico and Canada. ''A. simus'' evolved from ''A. pristinus'', but both species likely overlapped in the Middle Pleistocene. Of these species, ''A. simus'' was larger, is known from more complete remains, and is considered one of the most charismatic of North America's megafauna. Today considered to be an enormous omnivore, ''Arctodus simus'' is believed to be one of the largest known terrestrial mammalian carnivorans that has ever existed. However, ''Arct ...

Flat-headed Peccary
''Platygonus compressus'', the flat-headed peccary, is an extinct mammal species from the Tayassuidae family, that lived in North-America during the Pleistocene. It was first described in 1848 by John L. Leconte. Description The flat-headed peccary was about 75 cm (29.5 in) in shoulderheight and about 30 kg (66.1 lb) in weight. Other sources have estimated it to be similar in size to the European Wild Boar. Sizes differ between the place they have been found. Fossil skulls suggest a small brain, but a good sense of smell and sight. It has been suggested that the nasal cavity provided filtration for cold, dry and dusty air. ''Platygonus compressus'' had elongated limbs, a short humerus, broad and erect thoracic vertebrae and a large scapula. Therefore it has been suggested that this species may have been fleeter on foot than modern peccary species. Otherwise they probably appeared very similar to their closest living relative, the Chacoan peccary. Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beaver
Beavers are large, semiaquatic rodents in the genus ''Castor'' native to the temperate Northern Hemisphere. There are two extant species: the North American beaver (''Castor canadensis'') and the Eurasian beaver (''C. fiber''). Beavers are the second-largest living rodents after the capybaras. They have stout bodies with large heads, long chisel-like incisors, brown or gray fur, hand-like front feet, webbed back feet and flat, scaly tails. The two species differ in the shape of the skull and tail and fur color. Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges. Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams impound water and lodges serve as shelters. Their infrastructure creates wetlands used by many other species, and because of their effect on other organisms in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohio
Ohio () is a state in the Midwestern region of the United States. Of the fifty U.S. states, it is the 34th-largest by area, and with a population of nearly 11.8 million, is the seventh-most populous and tenth-most densely populated. The state's capital and largest city is Columbus, with the Columbus metro area, Greater Cincinnati, and Greater Cleveland being the largest metropolitan areas. Ohio is bordered by Lake Erie to the north, Pennsylvania to the east, West Virginia to the southeast, Kentucky to the southwest, Indiana to the west, and Michigan to the northwest. Ohio is historically known as the "Buckeye State" after its Ohio buckeye trees, and Ohioans are also known as "Buckeyes". Its state flag is the only non-rectangular flag of all the U.S. states. Ohio takes its name from the Ohio River, which in turn originated from the Seneca word ''ohiːyo'', meaning "good river", "great river", or "large creek". The state arose from the lands west of the Appalachian Mountai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
