The Carboniferous is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period 358.9 million years ago (mya), to the beginning of the Permian Period, 298.9 mya. The name Carboniferous means "coal-bearing", from the Latin carbō ("coal") and ferō, and refers to the many coal beds formed globally during that time.
The Mississippian is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.9 to 323.2 million years ago. As with most other geochronologic units, the rock beds that define the Mississippian are well identified, but the exact start and end dates are uncertain by a few million years. The Mississippian is so named because rocks with this age are exposed in the Mississippi Valley.
The Pennsylvanian is, in the ICS geologic timescale, the younger of two subperiods of the Carboniferous Period. It lasted from roughly 323.2 million years ago to 298.9 million years ago. As with most other geochronologic units, the rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-producing beds of this age are widespread.
The Pennsylvanian is a 444-mile (715 km) daily daytime Amtrak train running between New York City and Pittsburgh via Philadelphia. The trains travel across the Appalachian Mountains, through Pennsylvania's capital Harrisburg, the Pennsylvania Dutch Country, suburban and central Philadelphia, and New Jersey en route to New York. The entire train ride takes about 9 hours total: 1.5 hours between New York and Philadelphia, 2 hours between Philadelphia and Harrisburg, and 5.5 hours between Harrisburg and Pittsburgh.
The Daily Pennsylvanian, Inc. is the independent student media organization of the University of Pennsylvania. The DP, Inc. publishes The Daily Pennsylvanian newspaper, 34th Street Magazine, and Under the Button, as well as five newsletters: The Daily Pennsylvanian, The Weekly Roundup, The Toast, Quaker Nation, and Penn, Unbuttoned.
The Altoona Transportation Center is an intermodal passenger facility in downtown Altoona, Pennsylvania. It is served by the daily Amtrak Pennsylvanian, Greyhound Lines intercity buses, and AMTRAN local bus service. The station was built in 1986, replacing a temporary station, which had in turn replaced the 1887-built Pennsylvania Railroad station in 1972.
The Gzhelian is an age in the ICS geologic timescale or a stage in the stratigraphic column. It is the youngest stage of the Pennsylvanian, the youngest subsystem of the Carboniferous. The Gzhelian lasted from 303.7 to 298.9 Ma. It follows the Kasimovian age/stage and is followed by the Asselian age/stage, the oldest subdivision of the Permian system.
Embolomeri is an order of tetrapods or stem-tetrapods, possibly members of Reptiliomorpha. Embolomeres first evolved in the Early Carboniferous (Mississippian) Period and were the largest and most successful predatory tetrapods of the Late Carboniferous (Pennsylvanian) Period. They were specialized semiaquatic predators with long bodies for eel-like undulatory swimming. Embolomeres are characterized by their vertebral centra, which are formed by two cylindrical segments, the pleurocentrum at the rear and intercentrum at the front. These segments are equal in size. Most other tetrapods have pleurocentra and intercentra which are drastically different in size and shape.
The Pennsylvanian Pottsville Formation is a mapped bedrock unit in Pennsylvania, western Maryland, West Virginia, Ohio, and Alabama. It is a major ridge-former in the Ridge-and-Valley Appalachians of the eastern United States. The Pottsville Formation is conspicuous at many sites along the Allegheny Front, the eastern escarpment of the Allegheny or Appalachian Plateau.
The Paradox Basin is an asymmetric foreland basin located mostly in southeast Utah and southwest Colorado, but extending into northeast Arizona and northwest New Mexico. The basin is a large elongate northwest to southeast oriented depression formed during the late Paleozoic Era. The basin is bordered on the east by the tectonically uplifted Uncompahgre Plateau, on the northwest by the San Rafael Swell and extends partway into the Monument Uplift to the west.
The Eugeneodontida, sometimes also called Eugeneodontiformes, is an extinct and poorly known order of cartilaginous fishes. They possessed "tooth-whorls" on the symphysis of either the lower or both jaws and pectoral fins supported by long radials. They probably lacked pelvic fins and anal fins. The palatoquadrate was either fused to the skull or reduced. Now determined to be within the Holocephali, their closest living relatives are ratfish. The eugeneodonts are named after paleontologist Eugene S. Richardson, Jr. The Eugeneodontida disappeared in the Early Triassic. The geologically youngest fossils of the group are known from the Sulphur Mountain Formation, Vardebukta Formation and Wordie Creek Formation (Greenland).
The Westphalian is a stage or age in the regional stratigraphy of northwest Europe, with an age between roughly 319 and 307.5 Ma. It is a subdivision of the Carboniferous system or period and the regional Silesian series. The Westphalian is named for the region of Westphalia in western Germany where strata of this age occur. The Coal Measures of England and Wales are also largely of Westphalian age, though they also extend into the succeeding Stephanian.

W. Gerard "Jerry" Oleksiak is a Democratic politician who served as the Secretary of the Pennsylvania Department of Labor and Industry under Governor Tom Wolf from 2017 until his retirement in December 2020.
The 1911 Lehigh Brown and White football team was an American football team that represented Lehigh University as an independent during the 1911 college football season. In its second and final season under head coach Howard R. Reiter, the team compiled a 5–5–1 record and outscored opponents by a total of 91 to 82. The team played its home games at Lehigh Field in South Bethlehem, Pennsylvania.
The 1920–21 Penn Quakers men's ice hockey season was the 9th season of play for the program.
Rick Chester Krajewski is an American politician who currently serves in the Pennsylvania House of Representatives representing the 188th legislative district. A member of the Democratic Party and the Democratic Socialists of America, Krajewski was first elected during the 2020 Pennsylvania House of Representatives election, when he primaried incumbent Democrat Jim Roebuck.
Patrick Dele-Cole is a Nigerian politician, journalist, historian, and diplomat who in 1976 became the managing director of the Daily Times. He was also a presidential candidate of the Social Democratic Party in the early 1990s and was Nigeria's ambassador to Argentina and Brazil.
Eobaphetes is an extinct genus of embolomere which likely lived in the Pennsylvanian of Kansas. The genus is based on several skull and jaw fragments of a single individual. They were originally described under the species Erpetosuchus kansasensis, but this was later changed to Eobaphetes kansasensis when it was determined that Erpetosuchus was preoccupied by a Triassic reptile.
