Tramuntanasaurus
' is an extinct genus of moradisaurine captorhinid that lived during the late Early Permian (Artinskian–Kungurian) or early Middle Permian (early Roadian) in what is now the island of Mallorca of the Balearic Islands. The genus is only known by its type species, ', which was named in 2023 by Rafel Matamales-Andreu, Eudald Mujal, Àngel Galobart and Josep Fortuny, from an almost complete skeleton discovered in 2019. Etymology The genus is named after the Serra de Tramuntana, the main mountain range of Mallorca, where the holotype was found, and from ''saurus'', which means "lizard" in Latin. The specific epithet honors the discoverer of the specimen, Sebastià (Tià) Matamalas Riera, who is also the father of Rafel Matamales-Andreu. Description ''Tramuntanasaurus'' was a medium-sized captorhinid, measuring about long from head to tail. The skull is long and wide. It is distinctly triangular in dorsal view, where it shows a gradual narrowing towards its anterior end but with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moradisaurine
Captorhinidae is an extinct family of tetrapods, traditionally considered primitive reptiles, known from the late Carboniferous to the Late Permian. They had a cosmopolitan distribution across Pangea. Description Captorhinids are a clade of small to very large lizard-like animals that date from the Late Carboniferous through the Permian. Their skulls were much stronger than those of their relatives, the protorothyridids, and had teeth that were better able to deal with tough plant material. The postcranial skeleton is similar to those of seymouriamorphs and diadectomorphs; these animals were grouped together with the captorhinids in the order Cotylosauria as the first reptiles in the early 20th century, but are now usually regarded as stem-amniotes no closer to reptiles than to mammals. Captorhinids have broad, robust skulls that are generally triangular in shape when seen in dorsal view. The premaxillae are characteristically downturned. The largest captorhinid, the herbivorous ...

Extinction
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Anatomical Terms Of Location
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

Orbit (anatomy)
In anatomy Anatomy () is the branch of morphology concerned with the study of the internal structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old scien ..., the orbit is the Body cavity, cavity or socket/hole of the skull in which the eye and Accessory visual structures, its appendages are situated. "Orbit" can refer to the bony socket, or it can also be used to imply the contents. In the adult human, the volume of the orbit is about , of which the eye occupies . The orbital contents comprise the eye, the Orbital fascia, orbital and retrobulbar fascia, extraocular muscles, cranial nerves optic nerve, II, oculomotor nerve, III, trochlear nerve, IV, trigeminal nerve, V, and abducens nerve, VI, blood vessels, fat, the lacrimal gland with its Lacrimal sac, sac and nasolacrimal duct, duct, the eyelids, Medial palpebral ligament, medial and Lateral palpebral raphe, lateral palpebr ...

Jugal Bone
The jugal is a skull bone found in most reptiles, amphibians and birds. In mammals, the jugal is often called the malar or zygomatic bone, zygomatic. It is connected to the quadratojugal and maxilla, as well as other bones, which may vary by species. Anatomy The jugal bone is located on either side of the skull in the Ocular scales, circumorbital region. It is the origin of several masticatory muscles in the skull. The jugal and Lacrimal bone, lacrimal bones are the only two remaining from the ancestral circumorbital series: the prefrontal, postfrontal, postorbital, jugal, and lacrimal bones. During development, the jugal bone originates from dermal bone. In dinosaurs This bone is considered key in the determination of general traits in cases in which the entire skull has not been found intact (for instance, as with dinosaurs in paleontology). In some dinosaur genera the jugal also forms part of the lower margin of either the antorbital fenestra or the infratemporal fenestr ...

Frontal Bone
In the human skull, the frontal bone or sincipital bone is an unpaired bone which consists of two portions.'' Gray's Anatomy'' (1918) These are the vertically oriented squamous part, and the horizontally oriented orbital part, making up the bony part of the forehead, part of the bony orbital cavity holding the eye, and part of the bony part of the nose respectively. The name comes from the Latin word ''frons'' (meaning "forehead"). Structure The frontal bone is made up of two main parts. These are the squamous part, and the orbital part. The squamous part marks the vertical, flat, and also the biggest part, and the main region of the forehead. The orbital part is the horizontal and second biggest region of the frontal bone. It enters into the formation of the roofs of the orbital and nasal cavities. Sometimes a third part is included as the nasal part of the frontal bone, and sometimes this is included with the squamous part. The nasal part is between the brow ridges, ...

Labidosaurikos
''Labidosaurikos'' is a genus of extinct captorhinid tetrapods that lived around 279 to 272 million years ago during Kungurian age of the lower Permian. The American paleontologist John Willis Stovall first described ''Labidosaurikos'' in 1950, naming it "Labidosaurus like" for the striking similarity of the holotype skull of his specimen to the cranial anatomy of another captorhinid ''Labidosaurus hamatus''.Stovall, J.W., 1950. A new cotylosaur from north central Oklahoma. ''American Journal of Science'', 248(1), pp.46-54. ''Labidosaurikos'' is an important find in Red Beds of Texas and Oklahoma, Permian red beds of North America, where captorhinids are commonly found, as it is a key discovery in the evolution of herbivory in large captorhinids given its multi-row tooth plates.LeBlanc, A.R., Brar, A.K., May, W.J. and Reisz, R.R., 2015.

Gecatogomphius
''Gecatogomphius'' is an extinct genus of Middle Permian captorhinid with multiple tooth rows known from the Kirov Oblast and the Republic of Tatarstan of Russia. Description ''Gecatogomphius'' is known from the holotype PIN 1156/1, a three-dimensionally preserved nearly complete lower jaw found on the bank of the Vyatka River near the town of Gorki in the Kirov Oblast, and from PIN 4310/1 a single maxillary tooth plate from Berezovye Polyanki in Tatarstan. The preserved part of the jawbone fragment has a length of 80 millimeters and is posteriorly expanded to form a very broad shelf that bears five rows of bulbous teeth. ''Gecatogomphius'' is part of the biostratigraphic Ocher Assemblage which is characteristic for sediments of the East European Platform with an uppermost Lower Permian (Upper Kungurian) and lower Middle Permian (Roadian) age. Etymology ''Gecatogomphius'' was first named by B. P. Vjushkov and Pjotr K. Chudinov in 1957 and the type species is ''Gecatogomphiu ...
