Arkansaurus
''Arkansaurus'' (meaning "Arkansas lizard") is an extinct genus of ornithomimosaurian theropod dinosaur. It lived during the Albian and Aptian stages of the Early Cretaceous. The type and only species is ''Arkansaurus fridayi''. History In August 1972, Joe B. Friday, who owned a service station in Locksburg, Arkansas, noticed some vultures circling above his land. Checking his cows, he noticed that fossil bones were visible in a ditch near the road where some gravel had been removed recently for the reconstruction of Arkansas Highway 24. He removed them and for some months displayed the fossils in his station. At the time, nobody recognised them for dinosaur bones.McDonnold, Paul, 2014, "Them Dry Bones", ''Arkansas Life'', September 2014, pp 80–85 A geology professor at the University of Arkansas and former resident of the nearby town of Nashville, Doy Zachry Jr., took the bones to his colleague at the University of Arkansas, paleontologist Dr. James H. Quinn, to view. Quinn rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithomimosauria
Ornithomimosauria ("bird-mimic lizards") are theropod dinosaurs which bore a superficial resemblance to the modern-day ostrich. They were fast, omnivorous or herbivorous dinosaurs from the Cretaceous Period (geology), Period of Laurasia (now Asia, Europe and North America), as well as Africa and possibly Australia. The group first appeared in the Early Cretaceous and persisted until the Late Cretaceous. Primitive members of the group include ''Nqwebasaurus'', ''Pelecanimimus'', ''Shenzhousaurus'', ''Hexing'' and ''Deinocheirus'', the arms of which reached 2.4 m (8 feet) in length. More advanced species, members of the family Ornithomimidae, include ''Gallimimus'', ''Struthiomimus'', and ''Ornithomimus''. Some paleontologists, like Paul Sereno, consider the enigmatic Alvarezsauridae, alvarezsaurids to be close relatives of the ornithomimosaurs and place them together in the superfamily Ornithomimoidea (see classification below).

Trinity Group (geologic Formation)
The Trinity Group is a group (stratigraphy), group (sequence of rock strata) in the Lower Cretaceous lithostratigraphy of Texas, Arkansas, Mississippi, Louisiana and Oklahoma. It is named for the Trinity River (Texas), Trinity River of Texas. A stratigraphic column at the Mount Bonnell Fault location starts with the Lower Cretaceous Trinity Group overlain by the Edwards Group. Upper Cretaceous formation (geology), formations follow, starting with the Del Rio Clay, Buda Limestone, and then the Eagle Ford Group. Formations within the Trinity Group include the Hammett Formation, Cow Creek Formation, Hensel Formation, and Lower and Upper Glen Rose Formation. The Hammett and the lower portion of the Upper Glen Rose act as confining units (or aquitard) for the Middle Trinity Aquifer. The Upper Glen Rose contains the Upper Trinity Aquifer, which appears to have intra-aquifer groundwater flow with the Edwards Aquifer as water levels are at the same elevation.

Arkansas Museum Of Discovery
The Museum of Discovery, formerly the Arkansas Museum of Natural History and Antiquities, is located in downtown Little Rock, Arkansas. The museum is housed in a historic building in the River Market District (Little Rock, Arkansas), River Market District on the Arkansas River. The museum has a focus on STEM education, and all of the exhibits are interactive. It features a record-breaking musical bi-polar tesla coil, and also includes a large live animal collection. History Prolific writer and prohibitionist, Bernie Babcock, established the Arkansas Museum of Natural History and Antiquities in 1927 in response to criticism from H.L. Mencken that Arkansans were "bumpkins" who lacked cultural centers. Babcock first opened her museum in a downtown storefront on Main Street. Her museum had several sensational exhibits, such as the supposed head of a Chicago criminal and the King Crowley, now considered the greatest archaeological fake in Arkansas history. Her collection also includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tower Building Of The Little Rock Arsenal

Nomen Nudum
In taxonomy, a ''nomen nudum'' ('naked name'; plural ''nomina nuda'') is a designation which looks exactly like a scientific name of an organism, and may have originally been intended to be one, but it has not been published with an adequate description. This makes it a "bare" or "naked" name, which cannot be accepted as it stands. A largely equivalent but much less frequently used term is ''nomen tantum'' ("name only"). In zoology According to the rules of zoological nomenclature a ''nomen nudum'' is unavailable; the glossary of the ''International Code of Zoological Nomenclature'' gives this definition: And among the rules of that same Zoological Code: In botany According to the rules of botanical nomenclature a ''nomen nudum'' is not validly published. The glossary of the ''International Code of Nomenclature for algae, fungi, and plants'' gives this definition: The requirements for the diagnosis or description are covered by articles 32, 36, 41, 42, and 44.

Lockesburg, Arkansas
Lockesburg is a city in Sevier County, Arkansas, United States. The population was 739 at the 2010 census. History Though Lockesburg became the county seat on January 18, 1869, it was not incorporated until November 7, 1878. The land was donated by three members of a prominent local family--James, William, and Matthew Locke—and one Royal Appleton, for creation of a new county seat after an area of Sevier County was carved away to become part of newly created Little River County, and the existing county seat, Paraclifta, was no longer centrally located. The town’s growth was stunted when a major railroad bypassed the town for De Queen in 1897, along with a subsequent loss of county seat status to De Queen in 1905. But the timber industry served to boost the fortunes of the town in the Twentieth Century. Geography Lockesburg is located at (33.969852, -94.171034). According to the United States Census Bureau, the town has a total area of , all land. Demographics As of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

Nedcolbertia
''Nedcolbertia'' is a genus of theropod dinosaur from the Early Cretaceous Period of North America. Discovery and naming Three skeletons of a theropod were discovered in 1993 by Christopher Whittle near Cisco in the basal Yellow Cat Member of the Cedar Mountain Formation of Utah, dating to the Valanginian. These were subsequently studied and reported in 1995 by Kirkland, Britt, Madsen and Burge.J. I. Kirkland, C. H. Whittle, B. B. Britt, S. Madsen and D. Burge. A Small Theropod from the Basal Cedar Mountain Formation (Lower Cretaceous, Barremian) of Eastern Utah. Journal of Vertebrate Paleontology. 15(3), 39A (1995). Though in 1996 it had been announced that the taxon would be named "Nedcolbertia whittlei", in 1998 it was actually described and named by Kirkland, Whittle, Britt, Madsen and Burge as the type species ''Nedcolbertia justinhofmanni''. The generic name honours the American palaeontologist Edwin Harris Colbert, known as "Ned" to his friends. The specific name honou ...
