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 Ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arundel Formation
The Arundel Formation, also known as the Arundel Clay, is a clay-rich sedimentary rock formation, within the Potomac Group, found in Maryland of the United States of America. It is of Aptian age (Lower Cretaceous). This rock unit had been economically important as a source of iron ore, but is now more notable for its dinosaur fossils. It consists of clay lenses within depressions in the upper part of the Patuxent Formation that may represent oxbow swamp facies. It is named for Anne Arundel County, Maryland. Vertebrate paleofauna Dinosaurs Dinosaurs present include cf. ''Acrocanthosaurus'', the possible ornithischian ''Magulodon'', the poorly known theropods ''"Allosaurus" medius'', '' "Creosaurus" potens'', and ''"Coelurus" gracilis'', the ornithomimosaurian ''"Dryosaurus" grandis'', as well as another indeterminate ornithomimosaurian (though it most likely is ''Nedcolbertia''), the sauropod ''Astrodon'', the nodosaurid ''Priconodon'', a possible basal ceratopsian, and potential ...

Laurel, Maryland
Laurel is a city in Maryland, United States, located midway between Washington and Baltimore on the banks of the Patuxent River. While the city limits are entirely in northern Prince George's County, outlying developments extend into Anne Arundel, Montgomery and Howard counties. Founded as a mill town in the early 19th century, Laurel expanded local industry and was later able to become an early commuter town for Washington and Baltimore workers following the arrival of the Baltimore and Ohio Railroad in 1835. Largely residential today, the city maintains a historic district centered on its Main Street, highlighting its industrial past. The Department of Defense is 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 ar ...
