Montsecosuchus
''Montsecosuchus'' is an extinct genus of atoposaurid crocodylomorphs. It is the replacement generic name for ''Alligatorium depereti'', which was described in 1915 from the Montsec Lithographic Limestone quarry of Spain. Fossils found from this locality are from the Early Cretaceous, being Upper Berriasian-Lower Valanginian in age, belonging to the La Pedrera de Rúbies Formation While many publications concerning atoposaurids after 1915 have included mentions of ''A. depereti'', none has offered a redescription or revision of the species, though some recognized that great differences existed between it and other members of the genus. In these publications, the skull of ''A. depereti'' was shorter in relation to body length than any other species of ''Alligatorium'' (being less than half of the presacral length), and this may have been evidence for the genetic distinction of the species, although no replacement name was proposed. However, better preparation of the holotype speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atoposauridae
Atoposauridae is a Family (biology), family of crocodile-line archosaurs belonging to Neosuchia. The majority of the family are known from Late Jurassic to Early Cretaceous marine deposits in France, Portugal, and Bavaria in southern Germany. The discovery of the genus ''Aprosuchus'', however, extends the duration of the lineage to the end of the Cretaceous in Romania.

La Huérguina Formation
The La Huérguina Formation (also known as the Calizas de La Huérguina Formation, La Huérguina Limestone Formation or as the Una Formation) is a geological formation in Spain whose strata date back to the Barremian stage of the Early Cretaceous.Martínez et al., 2017 Las Hoyas is a Konservat-Lagerstätte within the formation, located near the city of Cuenca, Spain. The site is mostly known for its exquisitely preserved dinosaurs, especially enantiornithines.Weishampel et al., 2004, pp.556-563 The lithology of the formation mostly consists of lacustarine limestone deposited in a freshwater wetland environment. Las Hoyas Taphonomy As a Konservat-Lagerstätten, the preservation is exceptional. This may be a result of three factors: Microbial mats, Obruption and Stagnation. Microbial mats may be responsible for the preservation of soft tissue in many fossils from Las Hoyas, like ''Pelecanimimus''' crest.

Alligatorium
''Alligatorium'' is an extinct genus of atoposaurid crocodylomorph from Late Jurassic marine deposits in France. Systematics The type species is ''A. meyeri'', named in 1871 from a single specimen from Cerin, eastern France. Two more nominal species, ''A. franconicum'', named in 1906, and ''A paintenense'', named in 1961, are based on now-missing specimens from Bavaria, southern Germany, and were synonymized into a single species, for which ''A. franconicum'' has priority. A 2016 review of Atoposauridae removed ''A. franconicum'' from ''Alligatorium'' and placed at Neosuchia ''incertae sedis''. ''Alligatorium depereti'', described in 1915, was reassigned to its own genus, ''Montsecosuchus ''Montsecosuchus'' is an extinct genus of atoposaurid crocodylomorphs.

La Pedrera De Rúbies Formation
The La Pedrera de Rúbies Formation is an Early Cretaceous ( late Berriasian to early Barremian geologic formation in Catalonia, Spain. The formation crops out in the area of the Montsec in the Organyà Basin. At the La Pedrera de Meià locality, the formation consists of rhythmically laminated, lithographic limestones that formed in the distal areas of a large, shallow coastal lake. It is noted for the exceptional preservation of articulated small vertebrates and insects, similar to that of the Solnhofen Limestone. Fossil content The La Pedrera de Rúbies Formation has yielded the enantiornithine bird '' Noguerornis'' and the scincogekkomorph lizard '' Pedrerasaurus'',Weishampel et al., 2004, pp. 517-607 and two species of Teiid lizard ''Meyasaurus'', ''M. fauri'' and ''M. crusafonti,'' the indeterminate avialan '' Ilerdopteryx'',Kellner, 2002 frogs '' Neusibatrachus wilferti'',Báez & Sanchiz, 2007, p.477 and '' Montsechobatrachus''.

Theriosuchus
''Theriosuchus'' is an extinct genus of atoposaurid neosuchian from Late Jurassic to Early Cretaceous of Europe (Hungary & southern England), Southeast Asia (Thailand) and western North America (Wyoming), with fragmentary records from Middle Jurassic and Early Cretaceous sites in China, Morocco, and Scotland. Taxonomy Three valid species are currently recognized: ''Theriosuchus pusillus'' from southern England, ''T. grandinaris'' from Thailand, and ''T. morrisonensis'' from the Morrison Formation of North America. ''Theriosuchus'' was previously assigned to Atoposauridae, but a 2016 cladistic analysis recovered it as a neosuchian more closely related to members of the family Paralligatoridae than to atoposaurids. Two species previously assigned to this genus, ''Theriosuchus ibericus'' and ''T. symplesiodon'', have been reassigned to the new genus ''Sabresuchus''. On the other hand, ''Theriosuchus guimarotae'' from Portugal has been reassigned to ''Knoetschkesuchus ''Knoets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossils Of Spain
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, Seashell, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in #Resin, amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock stratum, strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous Spain
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 the ...

Radius
In classical geometry, a radius ( : radii) of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the latin ''radius'', meaning ray but also the spoke of a chariot wheel. as a function of axial position ../nowiki>" Spherical coordinates In a spherical coordinate system, the radius describes the distance of a point from a fixed origin. Its position if further defined by the polar angle measured between the radial direction and a fixed zenith direction, and the azimuth angle, the angle between the orthogonal projection of the radial direction on a reference plane that passes through the origin and is orthogonal to the zenith, and a fixed reference direction in that plane.
