Clidastes Proph1DB
''Clidastes'' is an extinct genus of marine lizard belonging to the mosasaur family. It is classified as part of the Mosasaurinae subfamily, alongside genera like ''Mosasaurus'' and ''Prognathodon''. ''Clidastes'' is known from deposits ranging in age from the Coniacian to the early Campanian in the United States. ''Clidastes'' means "locked vertebrae", which originates from the Greek noun κλειδί, or kleid meaning key (akin to Latin ''claudere'' meaning to shut). This refers to how the vertebral processes allow the proximal heads of the vertebrae to interlock for stability and strength during swimming. It was one of the earliest hydropedalIn mosasaurs, the terms "hydropedal" and "plesiopedal" refers to varying limb conditions and varying degrees of adaptations for marine life. Plesiopedal mosasaurs, such as '' Dallasaurus'' or '' Tethysaurus'' were primitive and largely coastal, while later hydropedal mosasaurs were streamlined and well-adapted to marine life. mosasau ...

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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platecarpus
''Platecarpus'' ("flat wrist") is an extinct genus of aquatic lizards belonging to the mosasaur family, living around 84–81 million years ago during the middle Santonian to early Campanian, of the Late Cretaceous period. Fossils have been found in the United States and possible specimens in Belgium and Africa. A well-preserved specimen of ''Platecarpus'' shows that it fed on moderate-sized fish, and it has been hypothesized to have fed on squid, and ammonites as well. Like other mosasaurs, it was initially thought to have swum in an eel-like fashion, although another study suggests that it swam more like modern sharks. An exceptionally well-preserved specimen of ''P. tympaniticus'' known as LACM 128319 shows skin impressions, pigments around the nostrils, bronchial tubes, and the presence of a high-profile tail fluke, showing that it and other mosasaurs did not necessarily have an eel-like swimming method, but were more powerful, fast swimmers. It is held in the Natural Histo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maastrichtian
The Maastrichtian () is, in the ICS geologic timescale, the latest age (uppermost stage) of the Late Cretaceous Epoch or Upper Cretaceous Series, the Cretaceous Period or System, and of the Mesozoic Era or Erathem. It spanned the interval from . The Maastrichtian was preceded by the Campanian and succeeded by the Danian (part of the Paleogene and Paleocene). The Cretaceous–Paleogene extinction event (formerly known as the Cretaceous–Tertiary extinction event) occurred at the end of this age. In this mass extinction, many commonly recognized groups such as non-avian dinosaurs, plesiosaurs and mosasaurs, as well as many other lesser-known groups, died out. The cause of the extinction is most commonly linked to an asteroid about wide colliding with Earth, ending the Cretaceous. Stratigraphic definitions Definition The Maastrichtian was introduced into scientific literature by Belgian geologist André Hubert Dumont in 1849, after studying rock strata of the ...

Globidens
''Globidens'' ("Globe teeth") is an extinct genus of mosasaur lizard classified as part of the Globidensini tribe in the Mosasaurinae subfamily. ''Globidens alabamaensis'' was the first species of ''Globidens'' described, in a publication by Charles W. Gilmore (1912). It is used as the type specimen for ''Globidens''. ''Globidens'' belongs to the family Mosasauridae, which consists of several genera of predatory marine reptiles prevalent during the Late Cretaceous. Specimens of ''Globidens'' have been discovered in Syria, North America, Morocco, Angola, and Indonesia. Among mosasaurs, ''Globidens'' is probably most well known for its highly rounded, globe-like teeth. Description ''Globidens'' was a relatively medium sized mosasaur, measuring long and weighing . It was similar in appearance to other mosasaurs (streamlined body with flippers, a laterally flattened tail and powerful jaws).

The Osteology Of The Reptiles P67
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

Eonatator
''Eonatator'' is an extinct genus of marine lizard belonging to the mosasaur family. It is a close relative of ''Halisaurus'', and part of the same subfamily, the Halisaurinae. It is known from the Late Cretaceous of North America, Colombia and Sweden. Originally, this taxon was included within ''Halisaurus'', but was placed in its own genus, which also led to the subfamily Halisaurinae being created for the two genera. Discovery and naming ''Eonatator'' is known from the Smoky Hill Chalk Member of the Niobrara Chalk Formation ( Late Coniacian to Early Campanian) of Kansas, from the Eutaw Formation (Santonian) and Mooreville Chalk Formation ( Selma Group; Santonian-Lower Campanian) of Alabama (United States), from the Kristianstad Basin of southern Sweden (late early Campanian), and the unit Nivel de Lutitas y Arenas (Campanian) of the Olini Group in La Mesa, Colombia. The name ''Eonatator'' means "dawn swimmer" ( Greek ''eos'' = dawn + Latin ''natator'' = swimmer). Original ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
