Nevadadromeus
''Nevadadromeus'' (meaning "Nevada runner") is an extinct genus of small thescelosaurine ornithischian dinosaur, from the Willow Tank Formation of Nevada, United States. The genus contains a single species, ''N. schmitti'', which represents the first non-avian dinosaur named from Nevada. Discovery and naming The ''Nevadadromeus'' holotype specimen, NSC 2008-002 was discovered near the Valley of Fire in 2008 and the bones were prepared for an event in Henderson, Nevada in 2021. A second ornithopod from Nevada, a hadrosaur, was also leaked during the event, but it is was not ready for public view until 2022. ''Nevadadromeus'' was formally published in October 2022. In 2022, Bonde ''et al''. described ''Nevadadromeus'' as a new genus and species of thescelosaurine. The generic name, "''Nevadadromeus''", combines a reference to the Nevada, the state the holotype was discovered in, with the Greek "dromeus", meaning "runner".

Willow Tank Formation
The Willow Tank Formation is a geologic formation which outcrops in the U.S. state of Nevada. Initially believed to be of Early Cretaceous ( Albian) age, later studies have concluded that it was more likely to be of Late Cretaceous (Cenomanian) age, making it equivalent to the Cloverly and Cedar Mountain Formations. It was deposited in an anastomosed fluvial system. Paleofauna All paleofauna listed are taken from a list compiled by Bonde (2008a) unless stated otherwise. Non-dinosaurs * '' cf.

Thescelosaurine
Thescelosaurinae is a subfamily of thescelosaurid dinosaurs from the Early Cretaceous of Asia and the Late Cretaceous of North America. Distribution The distribution of Thescelosaurinae is quite large. They are widespread through United States and Canada where most of their fossils have been found. They also have a small group in North-Eastern China and Mongolia. Genera Studies disagree about which genera are included in the Thescelosaurinae. The group is defined to include ''Parksosaurus'' and '' Thescelosaurus'' and a cladistic analysis by C.M. Brown in 2013 concluded that the genera ''Changchunsaurus'', '' Haya'', ''Jeholosaurus'' and possibly ''Koreanosaurus'' are also thescelosaurines. Classification All thescelosaurines were originally included in the family Hypsilophodontidae, which is presently considered polyphyletic (unnatural). They are all now considered to be basal neornithischians, though more research is needed to be certain. They are the sister taxa to O ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Cretaceous North America
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow 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 ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by th ...

Cenomanian Life
The Cenomanian is, in the ICS' geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with a minor extinction event for marine speci ...

Orodromines
Orodrominae is a subfamily of thescelosaurid dinosaurs known from the Cretaceous of North America and Asia. Distribution Orodromines were a mostly North American based group with fossils from Canada and United States only. '' Albertadromeus'', as its name suggests, is only from the upper (later) part of the Oldman Formation in the Belly River Group of Alberta, Canada. '' Orodromeus'', the type genus, was widespread through Montana. Its holotype was found at the Egg Mountain in the Two Medicine Formation. ''Oryctodromeus'' fossils were found in the Lima Peaks section of the Blackleaf Formation, also from Montana. '' Zephyrosaurus'', the most widespread genus, lived in southern Montana and northern Wyoming. The locality of its holotype is the Wolf Creek Canyon, which is a sandstone in the Cloverly Formation. Age Orodromines are widespread throughout time, starting in the Aptian and ending in the Campanian. The earliest fossils are of '' Zephyrosaurus'' and are from the Aptian ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...
