The Devonian is a geologic period and system of the Paleozoic, spanning 60 million years from the end of the Silurian, 419.2 million years ago, to the beginning of the Carboniferous, 358.9 Mya. It is named after Devon, where rocks from this period were first studied; the first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, by the end of the period the first seed-bearing plants appeared. Various terrestrial arthropods became well-established. Fish reached substantial diversity during this time, leading the Devonian to be dubbed the "Age of Fishes." The first ray-finned and lobe-finned bony fish appeared, while the placoderms began dominating every known aquatic environment. The ancestors of all four-limbed vertebrates began adapting to walking on land, as their strong pectoral and pelvic fins evolved into legs.
In the oceans, primitive sharks became more numerous than in the Late Ordovician. The first ammonites, species of molluscs, appeared. Trilobites, the mollusc-like brachiopods and the great coral reefs, were still common; the Late Devonian extinction which started about 375 million years ago affected marine life, killing off all placodermi, all trilobites, save for a few species of the order Proetida. The palaeogeography was dominated by the supercontinent of Gondwana to the south, the continent of Siberia to the north, the early formation of the small continent of Euramerica in between; the period is named after Devon, a county in southwestern England, where a controversial argument in the 1830s over the age and structure of the rocks found distributed throughout the county was resolved by the definition of the Devonian period in the geological timescale. The Great Devonian Controversy was a long period of vigorous argument and counter-argument between the main protagonists of Roderick Murchison with Adam Sedgwick against Henry De la Beche supported by George Bellas Greenough.
Murchison and Sedgwick named the period they proposed as the Devonian System. While the rock beds that define the start and end of the Devonian period are well identified, the exact dates are uncertain. According to the International Commission on Stratigraphy, the Devonian extends from the end of the Silurian 419.2 Mya, to the beginning of the Carboniferous 358.9 Mya. In nineteenth-century texts the Devonian has been called the "Old Red Age", after the red and brown terrestrial deposits known in the United Kingdom as the Old Red Sandstone in which early fossil discoveries were found. Another common term is "Age of the Fishes", referring to the evolution of several major groups of fish that took place during the period. Older literature on the Anglo-Welsh basin divides it into the Downtonian, Dittonian and Farlovian stages, the latter three of which are placed in the Devonian; the Devonian has erroneously been characterised as a "greenhouse age", due to sampling bias: most of the early Devonian-age discoveries came from the strata of western Europe and eastern North America, which at the time straddled the Equator as part of the supercontinent of Euramerica where fossil signatures of widespread reefs indicate tropical climates that were warm and moderately humid but in fact the climate in the Devonian differed during its epochs and between geographic regions.
For example, during the Early Devonian, arid conditions were prevalent through much of the world including Siberia, North America, China, but Africa and South America had a warm temperate climate. In the Late Devonian, by contrast, arid conditions were less prevalent across the world and temperate climates were more common; the Devonian Period is formally broken into Early and Late subdivisions. The rocks corresponding to those epochs are referred to as belonging to the Lower and Upper parts of the Devonian System. Early DevonianThe Early Devonian lasted from 419.2 ± 2.8 to 393.3 ± 2.5 and began with the Lochkovian stage, which lasted until the Pragian. It spanned from 410.8 ± 2.8 to 407.6 ± 2.5, was followed by the Emsian, which lasted until the Middle Devonian began, 393.3± 2.7 million years ago. During this time, the first ammonoids appeared. Ammonoids during this time period differed little from their nautiloid counterparts; these ammonoids belong to the order Agoniatitida, which in epochs evolved to new ammonoid orders, for example Goniatitida and Clymeniida.
This class of cephalopod molluscs would dominate the marine fauna until the beginning of the Mesozoic era. Middle DevonianThe Middle Devonian comprised two subdivisions: first the Eifelian, which gave way to the Givetian 387.7± 2.7 million years ago. During this time the jawless agnathan fishes began to decline in diversity in freshwater and marine environments due to drastic environmental changes and due to the increasing competition and diversity of jawed fishes; the shallow, oxygen-depleted waters of Devonian inland lakes, surrounded by primitive plants, provided the environment necessary for certain early fish to develop such essential characteristics as well developed lungs, the ability to crawl out of the water and onto the land for short periods of time. Late DevonianFinally, the Late Devonian started with the Frasnian, 382.7 ± 2.8 to 372.2 ± 2.5, during which the first forests took shape on land. The first tetrapods appeared in the fossil record in the ensuing Famennian subdivisi
Chillicothe is a city in and the county seat of Ross County, United States. Located along the Scioto River 45 miles south of Columbus, Chillicothe was the first and third capital of Ohio, it is the center of the Chillicothe Micropolitan Statistical Area. The population was 21,901 at the 2010 census. Chillicothe is a designated Tree City USA by the National Arbor Day Foundation; the region around Chillicothe was the center of the ancient Hopewell tradition, which flourished from 200 BC until 500 AD. This Amerindian culture had trade routes extending to the Rocky Mountains, they built earthen mounds for ceremonial and burial purposes throughout the Scioto and Ohio River valleys. Native Americans who inhabited the area through the time of European contact included Shawnees. Present-day Chillicothe is the most recent of seven locations in Ohio that bore the name, because it was applied to the main town wherever the Chalakatha settled. Other population centers named Chillicothe in Ohio at one time include: one located at present-day Piqua, in Miami County.
After the Treaty of Greenville in 1795 forced the Native Americans from most of Ohio, European settlers came to the area. Migrants from Virginia and Kentucky moved west along the Ohio River in search of land; the community Chillicothe was founded in 1796 by a party led by General Nathaniel Massie on his land grant. The town's name comes from the Shawnee Chala·ka·tha, meaning "principal town", because it was the chief settlement of that division of the Shawnee people. In 1798, Ross County became incorporated with Chillicothe as the county seat. Chillicothe was named the capital of the remnant Northwest Territory in 1800, when Indiana Territory was split off, the Northwest Territory was reduced to Ohio, eastern Michigan and a sliver of southeastern Indiana. In 1802 as Ohio moved toward statehood, the city hosted the Ohio Constitutional Convention, it served as the capital of Ohio from statehood in 1803 until 1810 again from 1812-1816. Ohio was a free state, early migrants to Chillicothe included free blacks, who came to a place with fewer restrictions than in the slave states.
They aided runaway slaves coming north. As tensions increased prior to the breakout of the American Civil War, the free black community at Chillicothe maintained stations and aid to support refugees on the Underground Railroad; the Ohio River was a border with the slave states of the South, with slaves crossing the river to freedom, up the Scioto River to get more distance from their former homes and slave hunters. White abolitionists aided the Underground Railroad as well. Chillicothe is located at 39°20′11″N 82°59′2″W, it lies within the ecoregion of the Western Allegheny Plateau. It lies between the Scioto Paint Creek near their confluence. According to the United States Census Bureau, the city has a total area of 10.60 square miles, of which 10.43 square miles is land and 0.17 square miles is water. The city is surrounded by farming communities, Chillicothe residents describe the area as the foothills of the Appalachians; as the only city in the area, Chillicothe is a hub for economic activity.
Malls, prisons and a college campus are among the largest employers, but the most notable employer in the area is a Pixelle paper mill, in operation for over 100 years. The mill can sometimes create noxious odors, which residents refer to as “the smell of money”; as of the census of 2010, there were 21,901 people, 9,420 households, 5,559 families residing in the city. The population density was 2,099.8 inhabitants per square mile. There were 10,600 housing units at an average density of 1,016.3 per square mile. The racial makeup of the city was 88.1% White, 7.2% African American, 0.3% Native American, 0.5% Asian, 0.5% from other races, 3.4% from two or more races. Hispanic or Latino of any race were 1.3% of the population. There were 9,420 households of which 27.5% had children under the age of 18 living with them, 39.1% were married couples living together, 14.9% had a female householder with no husband present, 5.0% had a male householder with no wife present, 41.0% were non-families. 34.6% of all households were made up of individuals and 14.3% had someone living alone, 65 years of age or older.
The average household size was 2.25 and the average family size was 2.87. The median age in the city was 41.5 years. 21.8% of residents were under the age of 18. The gender makeup of the city was 47.6% male and 52.4% female. As of the census of 2000, there were 21,796 people, 9,481 households, 5,754 families residing in the city; the population density was 2,283.7 people per square mile. There were 10,303 housing units at an average density of 1,079.5 per square mile. The racial makeup of the city was 89.21% White, 7.51% African American, 0.34% Native American, 0.56% Asian, 0.04% Pacific Islander, 0.35% from other races, 2.00% from two or more races. Hispanic or Latino of any race were 0.84% of the population. There were 9,481 households out of which 25.8% had children under the age of 18
Hopewell Culture National Historical Park
Hopewell Culture National Historical Park is a United States national historical park with earthworks and burial mounds from the Hopewell culture, indigenous peoples who flourished from about 200 BC to AD 500. The park is composed of six separate sites in Ross County, including the former Mound City Group National Monument; the park includes archaeological resources of the Hopewell culture. It is administered by the United States Department of the Interior's National Park Service. In 2008, the Department of the Interior included Hopewell Culture National Historical Park as part of the Hopewell Ceremonial Earthworks, one of 14 sites on its tentative list from which the United States makes nominations for the UNESCO World Heritage Sites. From about 200 BC to AD 500, the Ohio River Valley was a central area of the prehistoric Hopewell culture; the term Hopewell culture is applied to a broad network of beliefs and practices among different Native American peoples who inhabited a large portion of eastern North America.
The culture is characterized by its construction of enclosures made of earthen walls built in geometric patterns, mounds of various shapes. Visible remnants of Hopewell culture are concentrated in the Scioto River valley near present-day Chillicothe, Ohio; the most striking Hopewell sites contain earthworks in the form of squares and other geometric shapes. Many of these sites were built to a monumental scale, with earthen walls up to 12 feet high outlining geometric figures more than 1,000 feet across. Conical and loaf-shaped earthen mounds up to 30 feet high are found in association with the geometric earthworks; the people who built them had a detailed knowledge of the local soils, they combined different types to provide the most stability to the works. It required the organized labor of thousands of man hours, as people carried the earth in handwoven baskets. Mound City, located on Ohio Highway 104 4 miles north of Chillicothe along the Scioto River, is a group of 23 earthen mounds constructed by the Hopewell culture.
Each mound within the group covered the remains of a charnel house. After the Hopewell people cremated the dead, they burned the charnel house, they constructed a mound over the remains. They placed artifacts, such as copper figures, projectile points and pipes in the mounds. European Americans first mapped the site in the 1840s; the archaeologists Ephraim George Squier and Edwin Hamilton Davis were the first excavators of the site and amassed a large collection of Mound artifacts, now preserved at the British Museum. Much of it was destroyed during World War I when the United States Army constructed a military training base, Camp Sherman, on the site. After the war, they razed the camp; the Ohio Historical Society conducted an archaeological excavation of the site from 1920–1922, followed by reconstruction of the mounds. In 1923, the Department of Interior declared the Mound City Group a National Monument, to be administered by the Federal government. In 1992, Mound City Group was expanded as Hopewell Culture National Historic Park.
Its definition included remnants of four other nearby mound systems. Two Ross County sites open to the public. Seip Earthworks is located 17 miles west of Chillicothe on U. S. Route 50. Hopewell Mound Group is the site of the 1891 excavation on the land of Mordecai Hopewell. Hopeton Earthworks located across the Scioto River from Mound City and High Bank Works, closed to the public; the Ohio Historical Society maintains a number of mound systems and elaborate earthworks in the southern Ohio area, including the National Historic Landmarks of Fort Ancient, Newark Earthworks, Serpent Mound. Fifteen mound complexes earlier identified in the county have been lost to agriculture or urban development; the national park contains nationally significant archaeological resources, including large earthwork and mound complexes. These provide insight into the sophisticated and complex social, ceremonial and economic life of the Hopewell people; the park visitor's center features museum exhibits with artifacts excavated from the Mound City Group, an orientation film, book sales area, self-guided and guided tours.

A glacial period is an interval of time within an ice age, marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods; the last glacial period ended about 15,000 years ago. The Holocene epoch is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Within the Quaternary, there have been a number of interglacials; the last glacial period was the most recent glacial period within the Quaternary Ice Age, occurring in the Pleistocene epoch, which began about 110,000 years ago and ended about 15,000 years ago. The glaciations that occurred during this glacial period covered many areas of the Northern Hemisphere and have different names, depending on their geographic distributions: Wisconsin, Midlandian, Würm, Dali, Taibai Luojishan, Tianchi Qomolangma, Llanquihue; the glacial advance reached its maximum extent about 18,000 BP. In Europe, the ice sheet reached Northern Germany.
In the last 650,000 years, there were, on average, seven cycles of glacial retreat. Since orbital variations are predictable, computer models that relate orbital variations to climate can predict future climate possibilities. Work by Berger and Loutre suggests; the amount of heat trapping gases emitted into Earth's Oceans and atmosphere will prevent the next glacial period, which otherwise would begin in around 1,000 years, more glacial cycles
Circleville is a city in and the county seat of Pickaway County, United States, along the Scioto River 25 miles south of Columbus. The population was 13,314 at the 2010 census; the city is best-known today as the host of the Circleville Pumpkin Show, an annual festival held since 1903. The city's name is derived from its original layout created in 1810 within the 1,100 ft diameter of a circle of a Hopewell tradition earthwork dating to the early centuries of the Common Era; the county courthouse was built in the center of the innermost circle. By the late 1830s, for numerous reasons residents decided to gain authorization from the state legislature to change the layout to a standard grid, accomplished by the mid-1850s. All traces of the Hopewell earthwork were destroyed in Circleville, although hundreds of other monuments may be found in the Ohio Valley. By the mid-18th century, the Lenape were pushed west from Pennsylvania by European settlers flowing into the colony; the Lenape were given permission by the Wyandot people to settle in the Ohio country.
One of their settlements was Maguck, built by 1750 on the banks of the Scioto River. Modern Circleville was built to the north of this site; the frontier explorer Christopher Gist was the first recorded European visitor to the Circleville area. Gist reached Maguck, the small Lenape village of about 10 families on the east bank of the Scioto River, on January 20, 1751, he wrote. Between the time of establishment of the United States and of the city's settlement, the land was owned by the US federal government, as opposed to other land in the county, part of the Virginia Military District. On January 12, 1810, Pickaway County was established by order of the Ohio General Assembly. On February 19 of that year, the assembly appointed David Bradford, George Jackson, Hohn Pollock to choose the location for the county seat; the men inspected numerous sites. At the time, the Hopewell fortifications were still intact, were selected for the site. An 1880 history of the county presumes that the men thought the site location would spur the preservation and maintenance of the Hopewell mounds.
The group was given a director on July 25 to oversee them, with Daniel Dreisbach appointed. Dreisbach was to purchase the land, determine lots, distribute them. At the time, the land was owned by Zeiger Jr. and Samuel Watt. Circleville was founded by European-American settlers during 1810, as people relocated westward after the American Revolutionary War; the first sale of property in the new town was followed with a celebration: a barbecue, the manufacture of a several-hundred-pound wheel of cheese, drawn to the barbecue on a sled. A competition for the honor of constructing the first house took place. By 1827, the town had 725 people in 102 individual houses, a courthouse, government office building, a private and public school, one church, nine stores, three pharmacies, three groceries, a market house. All were built except the jail, built in stone; the settlement was formally incorporated as the town of Circleville in 1814, it was made a city on March 25, 1853. Dissatisfaction among residents rose over Circleville's layout, however.
Some believed the design was "childish sentimentalism", others complained that the lots were too irregular and inconvenient, that a circular plan wasted space that could become profitable. As well, the space around the central courthouse was unpresentable. People from the countryside would hitch their horses around the courthouse, which would draw hogs and domestic animals to the area and surrounding city. In March 1837 at the request of the town, the Ohio General Assembly authorized the town to make the alterations, given the consent of all property owners in the circle. In March 1838, after no activity, the assembly authorized alterations to any quarter of the circle given consent from property owners in the quarter; the "Circleville Squaring Company" was created to convert the town plan into a squared grid, as was typical of other platted towns. That month, the southeast corner was the first to be altered, followed by the northwest quarter in September 1838; the northeast corner was only squared in 1849, the final quarter, the southwest, was altered in 1856.
The work involved destroying, moving, or constructing buildings and repaving roads, more. Due to these changes, no traces of the original earthworks remain, beside a section of elevated ground at the corner of Pickaway and Franklin streets; the only drawings of Circleville before its squaring were made by G. F. Wittich, he made sketches of the courthouse, the circle, other buildings in 1836, used those and information from residents to create a map around 1860, which he made a watercolor of in 1870. A history of the county makes note that the citizens of Circleville regret the rare circular layout of the town was changed. During April 1967, Bingman's Drug Store and several neighboring buildings on West Main Street in downtown Circleville were destroyed when Lee Holbrook, the husband of a drug store employee, brought a wooden box containing bundled dynamite to the store and it detonated during a struggle with the store's staff. Holbrook and four store employees died in ensuing fire. Holbrook's wife was not at the store.
On October 13, 1999, an F-3 tornado hit the city, set off by a squall line moving through the region. The tornado touched down on the north side of town, doing substantial damage to a barber's shop and a masonry building. A furniture store was damaged with a hole in its roof, where it was reported
Dublin is a city in Franklin and Union counties in the U. S. state of Ohio. The population was 41,751 at the 2010 census. Dublin is a suburb of Ohio; each year in late May or early June, the city hosts the Memorial Tournament, a stop on golf's PGA Tour. There are several other golf courses in Dublin; the Riviera Golf Club was home to the American-Italian Golf Association. Tartan Fields Golf Club hosted the LPGA's Wendy's Championship for Children from 2002 through 2006. Dublin has a public golf course financed by the Muirfield association, as well as the Jack Nicklaus-designed The Country Club of Muirfield Village. Other annual events include the July 4 music event and The July 4 Parade, a St. Patrick's Day parade, the Dublin Irish Festival, the largest 3-day Irish festival in the world. Although its earliest settlements date back to 1802, the village that became Dublin did not begin to take shape until the arrival of the Sells family from Huntingdon, Pennsylvania. Brothers Peter and Benjamin Sells purchased 400 acres of land on the west bank of the Scioto River as a gift for their brother John.
In 1808, John Sells brought his family to the region, by 1810 he had begun to survey lots for the new village with his partner, an Irish gentleman named John Shields. According to historians, Shields is responsible for naming the town after his birthplace: "If I have the honor conferred upon me to name your village, with the brightness of the morn, the beaming of the sun on the hills and dales surrounding this beautiful valley, it would give me great pleasure to name your new town after my birthplace, Ireland." By 1833, Dublin contained only one store. In 1970, Dublin was still a small town with only 681 residents. However, the construction of Interstate 270 facilitated a population boom, spearheaded by the acquisition of major corporate headquarters such as Ashland Inc and Wendy's International. In addition, the growth of the Muirfield Village Golf Club and its residential subdivision attracted numerous affluent citizens to the growing suburb. Dublin was declared a city in 1987, after reaching a population of 5,000 residents.
As part of this boom Dublin expanded its area, annexing parts of Washington, Perry and Jerome townships. Dublin is located at 40°6′33″N 83°8′25″W. According to the United States Census Bureau, the city has a total area of 24.80 square miles, of which 24.44 square miles is land and 0.36 square miles is water. The Scioto River passes through Dublin. In this area the river and its tributaries cut deep gorges through the limestone bedrock, the riverbed is stony; some of these tributaries feature waterfalls. Located on the Glaciated Allegheny Plateau, Dublin has flat topography. There are numerous ravines surrounding the tributaries of the Scioto River, which make for steep cliffs in some areas. Elevations range from 780 feet above sea level where the Scioto River leaves the city at Hayden Run Road, while the high point is 1000 feet at Glacier Ridge Metro Park. Being a modern American suburb, the city is accessed by car. In addition to Interstate 270, U. S. Highway 33, State Route 161, State Route 745 pass through the city.
There is a 77-mile network of bike trails. Long term plans include expanding the trails further, as well as connecting them to the regional trail system to facilitate travel to downtown Columbus. COTA provides limited service in the southeast part of the city. Routes 56 and 58 provide express service from the commercial areas around Frantz and Rings Roads to Downtown Columbus during rush hour periods. Dublin is home to the headquarters of a number of companies, including Cardinal Health, IGS Energy, Stanley Steemer, Wendy's and Online Computer Library Center. Pacer International, a larger intermodal logistics provider, was headquartered in Dublin until its acquisition by XPO Logistics on March 31, 2014.
