Laurel is a city in Maryland, United States, located midway between Washington, D.C., and Baltimore on the banks of the Patuxent River, in northern Prince George's County. Its population was 30,060 at the 2020 census.

Largely residential today, the city maintains a historic district centered on its Main Street. The Department of Defense has a prominent presence in the Laurel area today, with the Fort Meade Army base, the NSA and Johns Hopkins' Applied Physics Laboratory all located nearby. Laurel Park, a thoroughbred horse racetrack, is located just outside the city limits. History Natural history Many dinosaur fossils from the Cretaceous Era are preserved in a park in Laurel.

City
A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agreed definition of the lower boundary for their size. In a narrower sense, a city can be defined as a permanent and Urban density, densely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, Public utilities, utilities, land use, Manufacturing, production of goods, and communication. Their density facilitates interaction between people, government organisations, government organizations, and businesses, sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution. Historically, city dwellers have been a small proportion of humanity overall, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patuxent River
The Patuxent River is a tributary of the Chesapeake Bay in the state of Maryland. There are three main river drainages for central Maryland: the Potomac River to the west passing through Washington, D.C., the Patapsco River to the northeast passing through Baltimore, and the Patuxent River between the two. The Patuxent drainage basin, watershed had a rapidly growing population of 590,769 in 2000.

Flowing in a generally southeastward direction, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astrodon
''Astrodon'' is a genus of large herbivorous sauropod dinosaur, measuring in length, in height and in body mass. It lived in what is now the eastern United States during the Early Cretaceous period, and fossils have been found in the Arundel Formation, which has been dated through palynomorphs to the Albian about 112 to 110 million years ago. Discovery and species Two dinosaur teeth were received in late November 1858 by chemist Philip Thomas Tyson from John D. Latchford. They had been found in Latchford's open iron ore pit in the Arundel Formation at Swampoodle near Muirkirk in Prince George's County, Maryland. Tyson let them be studied by the dentist Christopher Johnston, professor at the Baltimore Dental College, who cut one tooth in half and thereby discovered a characteristic star-formed cross-section. Johnston named ''Astrodon'' in 1859. However, he did not attach a specific epithet, so Joseph Leidy is credited with naming ''Astrodon johnstoni'' (the type species) ...

Dinosaur Park (Prince George's County, Maryland)
Dinosaur Park is a park located in the 13200 block of Mid-Atlantic Boulevard, near Laurel and Muirkirk, Maryland, and operated by the Prince George's County Department of Parks and Recreation. The park features a fenced area where visitors can join paleontologists and volunteers in searching for early Cretaceous fossils. The park also has an interpretive garden with plants and information signs. The park is in the approximate location of discoveries of '' Astrodon'' teeth and bones as early as the 19th century. In the 18th and 19th centuries, the clays of the Muirkirk Deposit in Prince George's County, Maryland were mined for siderite, or iron ore. Iron furnaces located throughout the region melted down siderite to produce iron and steel used in construction and manufacturing. In 1858, African-American miners working in open pit mines were the first to discover dinosaur fossils in Maryland. Among the first scientists to explore the Muirkirk Deposit was Maryland state geologist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 mya (unit), million years ago (Mya). It is the third and final period of the Mesozoic Era (geology), Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . The Cretaceous was a period with a relatively warm climate, resulting in high Sea level#Local and eustatic, eustatic sea levels that created numerous shallow Inland sea (geology), inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic gr ...

Thoroughbred Racing
Thoroughbred racing is a sport and industry involving the racing of Thoroughbred horses. It is governed by different national bodies. There are two forms of the sport – flat racing and jump racing, the latter known as National Hunt racing in the UK and steeplechasing in the US. Jump racing can be further divided into hurdling and steeplechasing. According to ''The Guardian'', the racing of Thoroughbreds has been steadily declining in popularity worldwide. Between 700 and 800 racehorses die in racing each year. Ownership and training of racehorses Traditionally, racehorses have been owned by wealthy individuals. It has become increasingly common in the last few decades for horses to be owned by syndicates or partnerships. Notable examples include the 2005 Epsom Derby winner Motivator, owned by the Royal Ascot Racing Club, 2003 Kentucky Derby winner Funny Cide, owned by a group of 10 partners organized as Sackatoga Stable, and 2008 Kentucky Derby winner Big Brown, owned b ...

Laurel Park (race Track)
Laurel Park, formerly Laurel Race Course, is an American thoroughbred racetrack located just outside Laurel, Maryland which opened in 1911. The track is miles in circumference. Its name was changed to "Laurel Race Course" for several decades until returning to the "Laurel Park" designation in 1994. In April 2024 the Maryland General Assembly approved a bill that would consolidate thoroughbred racing in Maryland to Pimlico Race Course in Baltimore. Laurel Park is expected to host the 2026 Preakness Stakes, and then permanently close for racing once renovations at Pimlico have been completed. History Laurel Park Racecourse opened October 2, 1911 under the direction of the Laurel Four County Fair. In 1914, New York businessmen and prominent horsemen, Philip J. Dwyer and James Butler purchased the track and appointed Matt Winn as the general manager. In 1918 the field was used by Army Engineers as a training camp before deployment to France. In 1946, a stable fire broke out with 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Applied Physics Laboratory
The Johns Hopkins University Applied Physics Laboratory (or simply Applied Physics Laboratory, or APL) is a not-for-profit university-affiliated research center (UARC) in Howard County, Maryland. It is affiliated with Johns Hopkins University and employs 8,700 people as of 2024. APL is the nation's largest UARC.

Fort George G
A fortification (also called a fort, fortress, fastness, or stronghold) is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin ("strong") and ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley Civilization were the first small cities to be fortified. In ancient Greece, large cyclopean stone walls fitted without mortar had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acted as a ...
