Malerisaurus
''Malerisaurus'' is an extinct genus of archosauromorph known from Andhra Pradesh of India and Texas of the USA. Description ''Malerisaurus'' was a medium-sized archosauromorph which averaged 1.2 meters in length. ''Malerisaurus'' is known from the holotype ISIR 150, two articulated and almost complete skeletons which were discovered as the presumable gastric contents of two skeletons of ''Parasuchus hislopi''. It was collected from the Lower Maleri Formation, dating to the late Carnian or early Norian stage of the Late Triassic. ''Malerisaurus robinsonae'' was a small archosauromorph, probably capable of climbing trees and swimming. The skull has some adaptations to a carnivorous diet, but is nevertheless unspecialised and probably more of an insectivore. ''Malerisaurus'', seen as a diapsid skull, shows primitive and advanced facies in its unossified laterosphenoid, absence of antorbital and mandibular fenestrae, gracile form, primitive girdles, elongated cervicals and a ...

Parasuchus
''Parasuchus'' is an extinct genus of basal phytosaur known from the Late Triassic (late Carnian to early Norian stage) of Andhra Pradesh and Madhya Pradesh, India. At its most restricted definition, ''Parasuchus'' contains a single species, ''Parasuchus hislopi''. ''Parasuchus hislopi'' is one of several species belonging to a basal grade of phytosaurs, typified by the genus '' Paleorhinus''. Historically, ''Paleorhinus'' has been known from better-described fossils, and many species have been lumped into that genus. ''Parasuchus hislopi'', despite being described earlier than ''Paleorhinus'', was considered an undiagnostic chimera until new neotype fossils were described in the late 1970s. ''Parasuchus hislopi'' and the two unambiguously valid species of ''Paleorhinus'' (''P. bransoni'' and ''P. angustifrons'') are all closely related; some authors have historically described them all under the species ''Paleorhinus'', while others place the two ''Paleorhinus'' species into ' ...

Trilophosaurus
''Trilophosaurus'' (Greek for "lizard with three ridges") is a lizard-like trilophosaurid allokotosaur known from the Late Triassic of North America. It was a herbivore up to 2.5 m long. It had a short, unusually heavily built skull, equipped with massive, broad flattened cheek teeth with sharp shearing surfaces for cutting up tough plant material. Teeth are absent from the premaxilla and front of the lower jaw, which in life were probably equipped with a horny beak. The skull is also unusual in that the lower temporal opening is missing, giving the appearance of a euryapsid skull. Because of this, the trilophosaurs were once classified with placodonts within Sauropterygia. Carroll (1988) suggested that the lower opening may have been lost to strengthen the skull. ''Trilophosaurus'' is traditionally thought to include two valid species: the typical ''T. buettneri'' and the more robust ''T. jacobsi''. In 1993, paleontologists Hans-Dieter Sues and Paul E. Olsen reassigned '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorado City Formation
The Colorado City Formation is a geologic formation in Texas, United States. It preserves fossils dating back to the Triassic period.

Lower Maleri Formation
The Lower Maleri Formation is a sedimentary geological formation, rock formation found in Andhra Pradesh and Telangana, India. It is the lowermost member of the Pranhita–Godavari Basin. It is of late Carnian to early Norian age (Upper Triassic), and is notable for its fossils of early dinosaurs, including the basal (phylogenetics), basal saurischian (possible theropod) ''Alwalkeria''.Weishampel et al., 2004, pp.525–527 Vertebrate fauna cf.

Prolacertiformes
Protorosauria is an extinct polyphyletic group of archosauromorph reptiles from the latest Middle Permian (Capitanian stage) to the end of the Late Triassic (Rhaetian stage) of Asia, Europe and North America. It was named by the English anatomist and paleontologist Thomas Henry Huxley in 1871 as an order, originally to solely contain ''Protorosaurus''. Other names which were once considered equivalent to Protorosauria include Prolacertiformes and Prolacertilia. Protorosaurs are distinguished by their long necks formed by elongated cervical vertebrae, which have ribs that extend backward to the vertebrae behind them. Protorosaurs also have a gap between the quadrate bones and the jugal bones in the back of the skull near the jaw joint, making their skulls resemble those of lizards. While previously thought to be monophyletic, the group is now though to consist of various groups of basal archosauromorph reptiles that lie outside Crocopoda. Classification Protorosauria was consi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junior Synonym
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia lev ...

Chinle Group
The Chinle Formation is an Upper Triassic continental geological formation of fluvial, lacustrine, and palustrine to eolian deposits spread across the U.S. states of Nevada, Utah, northern Arizona, western New Mexico, and western Colorado. In New Mexico, it is often raised to the status of a geological group, the Chinle Group. Some authors have controversially considered the Chinle to be synonymous to the Dockum Group of eastern Colorado and New Mexico, western Texas, the Oklahoma panhandle, and southwestern Kansas. The Chinle Formation is part of the Colorado Plateau, Basin and Range, and the southern section of the Interior Plains.GEOLEX database entry for Chinle USGS (viewed 19 March 2006) A probable separate depositional basin within the Chinle is found in northwestern Colorado and northeastern Ut ...

Texas Memorial Museum
The Texas Memorial Museum, located on the campus of the University of Texas at Austin in Austin, Texas, USA, was created during preparations for the Texas Centennial Exposition held in 1936. The museum's focus is on natural history, including paleontology, geology, biology, herpetology, ichthyology and entomology. At one point, the museum also had exhibits on Texas history, anthropology, geography, and ethnography, but these were relocated to other museums (including the Bullock Texas State History Museum) in 2001. The building was designed in the Art Deco style by John F. Staub, with Paul Cret as supervising architect. Ground was broken for the building by President Franklin D. Roosevelt in January 1936. The museum was opened on January 15, 1939. The museum won "Best of Austin" awards from the ''Austin Chronicle'' in 2002, 2005, and 2012. In October 2013, Linda Hicke, the dean of Austin's College of Natural Sciences, cut the museum's funding by $400,000 and transferred ownershi ...

Protorosaurus
''Protorosaurus'' ("first lizard") is a genus of lizard-like early reptiles. Members of the genus lived during the late Permian period in what is now Germany and Great Britain. Once believed to have been an ancestor to lizards, ''Protorosaurus'' is now known to be one of the oldest and most primitive members of Archosauromorpha, the group that would eventually lead to archosaurs such as crocodilians and dinosaurs. Description ''Protorosaurus'' grew up to in length, and was a slender, lizard-like animal, vaguely resembling a monitor lizard, with long legs and a long neck. Discovery ''Protorosaurus'' was one of the first fossil reptiles to be described, being initially described in Latin in 1710 by from a specimen found in Thuringia in Germany, who considered the animal to be a crocodile, and most similar to the Nile crocodile (''C. niloticus''). Over a century later, in publications in 1830 and 1832 Hermann von Meyer recognised ''Protorosaurus'' as distinct extinct reptile a ...

Mandibular Fenestrae
The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone. However two parts are more prominent: the cranium and the mandible. In humans, these two parts are the neurocranium and the viscerocranium (facial skeleton) that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In humans these sensory structures are part of the facial skeleton. Functions of the skull include protection of the brain, fixing the distance between the eyes to allow stereoscopic vision, and fixing the position of the ears to enable sound localisation of the direction and distance of sounds. In some animals, such as horned ungulates (mammals with hooves), the skull also has a defensive function by providing the mount (on the fronta ...
