Kyrinion
''Kyrinion'' is an extinct genus of baphetid tetrapod from the Late Carboniferous of England. It is known from a skull that was found in Tyne and Wear county dating back to the Westphalian (stage), Westphalian stage. Along with the skull is part of the lower jaw, an arch of the Atlas (anatomy), atlas bone (the vertebra that connects to the skull) and a rib possibly belonging to a cervical (neck) vertebra. The type species ''K. martilli'' was named from this material in 2003. Description The holotype skull of ''Kyrinion'' is well preserved with the back of the skull and both stapes, or ear bones, intact. The orbit (anatomy), orbits, or eye sockets, are somewhat triangular in shape. Areas connecting the palate with the jaws and braincase make the skull inflexible. Lateral lines, used for sensory perception in aquatic environments, are present on the quadratojugal bone behind the eyes. The lower jaw lacks the distinctive features of some other baphetids, such as teeth on the paras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megalocephalus
''Megalocephalus'' (meaning "big head") is an extinct genus of baphetid animal from the late Carboniferous ( Westphalian A-C) of the British Isles and the United States (Ohio). It contains two species, ''M. pachycephalus'' and ''M. lineolatus''. History ''Megalocephalus pachycephalus'' ''Megalocephalus pachycephalus'' is one of the most common large amphibians from the Carboniferous of Britain, and is known from several sites in England, Scotland, and Ireland. The first known fossils of the genus were cranial fragments which were misattributed to ''Rhizodus'' jaw bones upon their discovery in 1864. These fragments, and many subsequent discoveries, were recovered from a quarry near Newsham, Northumberland. Other ''Megalocephalus'' fossils found in the 1860s had been referred to other large amphibians, namely ''Pteroplax and'' ''Anthracosaurus''. Two well-preserved skulls and associated jaw bones were found in Newsham in 1870 and 1871, though these were also mistakenly refe ...

Baphetid
Baphetidae is an extinct family of early tetrapods. Baphetids were large labyrinthodont predators of the Late Carboniferous period ( Namurian through Westphalian) of Europe. Fragmentary remains from the Early Carboniferous of Canada have been tentatively assigned to the group. The phylogenetic relationships of baphetids is uncertain; while many studies have placed the group as a close relative of Amniota, other analyses have found Baphetidae to be a more basal clade of early stem tetrapods. Baphetids were among the first of the Carboniferous fossil tetrapods to be found and were originally described in 1850 by John William Dawson. The baphetids have been referred to the family Loxommatidae, but this group was later shown to be a junior synonym of Baphetidae, which was named earlier in 1865. Baphetids are known mainly from skulls; very little postcranial material has been found. Palaeobiology The presence of lateral lines and the long rows of needle-like teeth show that most wer ...

Loxomma
''Loxomma'' (meaning “slanting eyes”) is an extinct genus of Loxommatinae and one of the first Carboniferous tetrapods. They were first described in 1862 and further described in 1870 when two more craniums were found. It is mostly associated with the area of the United Kingdom. They share features with modern reptiles as well as with fish. They had 4 paddle-like limbs that they used to swim in lakes, but they breathed air. Their diet consisted mostly of live fish. They are of the family Baphetidae which are distinguished by their keyhole shaped orbits, while ''Loxomma'' themselves are distinguished by the unique texture on their skulls, said to be honeycomb-like. History and discovery The genus ''Loxomma'' was discovered and named by Thomas Henry Huxley in 1862 via a near perfect cranium, a vertebra and a rib in the Lanarkshire coal-field of Scotland. The family Baphetidae were among the first Carboniferous tetrapods to be found and were first described by William Da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quadratojugal
The quadratojugal is a skull bone present in many vertebrates, including some living reptiles and amphibians. Anatomy and function In animals with a quadratojugal bone, it is typically found connected to the jugal (cheek) bone from the front and the squamosal bone from above. It is usually positioned at the rear lower corner of the cranium. Many modern tetrapods lack a quadratojugal bone as it has been lost or fused to other bones. Modern examples of tetrapods without a quadratojugal include salamanders, mammals, birds, and squamates (lizards and snakes). In tetrapods with a quadratojugal bone, it often forms a portion of the jaw joint. Developmentally, the quadratojugal bone is a dermal bone in the temporal series, forming the original braincase. The squamosal and quadratojugal bones together form the cheek region and may provide muscular attachments for facial muscles. In reptiles and amphibians In most modern reptiles and amphibians, the quadratojugal is a prominent, strapl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newcastle Upon Tyne
Newcastle upon Tyne ( RP: , ), or simply Newcastle, is a city and metropolitan borough in Tyne and Wear, England. The city is located on the River Tyne's northern bank and forms the largest part of the Tyneside built-up area. Newcastle is also the most populous city of North East England. Newcastle developed around a Roman settlement called Pons Aelius and the settlement later took the name of a castle built in 1080 by William the Conqueror's eldest son, Robert Curthose. Historically, the city’s economy was dependent on its port and in particular, its status as one of the world's largest ship building and repair centres. Today, the city's economy is diverse with major economic output in science, finance, retail, education, tourism, and nightlife. Newcastle is one of the UK Core Cities, as well as part of the Eurocities network. Famous landmarks in Newcastle include the Tyne Bridge; the Swing Bridge; Newcastle Castle; St Thomas’ Church; Grainger Town including G ...

Whitley Bay
Whitley Bay is a seaside town in the North Tyneside borough in Tyne and Wear, England. It formerly governed as part of Northumberland and has been part of Tyne and Wear since 1974. It is part of the wider Tyneside built-up area, being around east of Newcastle upon Tyne. Two notable landmarks are the Spanish City (a domed building on the seafront) and St. Mary's Lighthouse, the latter on a small island near the town. History Early history Whitley was first mentioned around 1100 when King Henry I conferred it with other possessions on the Priory of Tynemouth being referred to in ancient documents and maps before that date as Witelei, Wyteley, Hwyteleg, Witelithe, Wheteley, Wytheleye, Whitlaw, Whitlathe and Whitlag. Whitley is also referred to in the charters of King Henry II, King Richard I and King John, confirming to the priors their possessions and liberties. Whitley was connected with the Crusades when Pope Nicholas IV granted to Edward I of England, Edward I the first-fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ironstone
Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron ore compound from which iron (Fe) can be smelted commercially. Not to be confused with native or telluric iron, which is very rare and found in metallic form, the term ''ironstone'' is customarily restricted to hard, coarsely banded, non-banded, and non-cherty sedimentary rocks of post-Precambrian age. The Precambrian deposits, which have a different origin, are generally known as banded iron formations. The iron minerals comprising ironstones can consist either of oxides, i.e. limonite, hematite, and magnetite; carbonates, i.e. siderite; silicates, i.e. chamosite; or some combination of these minerals.U.S. Bureau of Mines Staff (1996) ''Dictionary of Mining, Mineral, & Related Terms.''

Symphysis Menti
In human anatomy, the facial skeleton of the skull the external surface of the mandible is marked in the median line by a faint ridge, indicating the mandibular symphysis (Latin: ''symphysis menti'') or line of junction where the two lateral halves of the mandible typically fuse at an early period of life (1-2 years). It is not a true symphysis as there is no cartilage between the two sides of the mandible. This ridge divides below and encloses a triangular eminence, the mental protuberance, the base of which is depressed in the center but raised on either side to form the mental tubercle. The lowest (most inferior) end of the mandibular symphysis — the point of the chin — is called the "menton". It serves as the origin for the geniohyoid and the genioglossus muscles. Other animals Solitary mammalian carnivores that rely on a powerful canine bite to subdue their prey have a strong mandibular symphysis, while pack hunters delivering shallow bites have a weaker one.

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
