Morohasaurus
''Morohasaurus'' is an extinct genus of ''cf.'' Monstersauria, monstersaurian squamates know from a single left dentary from the Early Cretaceous (?Albian) Ohyamashimo Formation of the Sasayama Group in Tamba City, Hyogo Prefecture, Japan. The type and only species is ''Morohasaurus kamitakiensis.'' As of 2021, Ikeda ''et al.'' place this taxon ''a Cf.#Biological use, conferatur'' within Monstersauria based on general synapomorphies but without performing a phylogenetic analysis. The unique characters described in the paper to distinguish ''Morohasaurus kamitakiensis'' as a valid species include "the sinuous posteroventral rim of the dentary with a large U-shaped upper notch and small V-shaped lower notch, posteroventral corner of intramandibular septum with a weakly pointed eminence projecting posteriorly, and unicuspid, curved trenchant teeth with distinct blade-like carinae on their mesial and distal sides without grooves or serrations." If its presumed affinities are correct, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monstersauria
Monstersauria is a clade of anguimorph lizards, defined as all taxa more closely related to ''Heloderma'' than '' Varanus''. It includes ''Heloderma'', as well as several extinct genera, such as ''Estesia'', '' Primaderma'' and ''Gobiderma'', but it was found to be polyphyletic in the most recent and complete squamate phylogenetic analysis by Reeder ''et al.'' (2015). Classification Traditionally, Monstersauria was thought to include the modern Helodermatidae along with fossil genera such as ''Gobiderma'' and ''Estesia'' on the finding that it was a sister to Varanidae. But in more recent years, such as 2004 and 2008, more precise molecular studies have shown that the extant ''Heloderma'' is closer to Anguidae & kin than to Varanoidea. A large-scale integrated analysis on squamate phylogeny incorporating 737 characters of morphological and molecular data in 2015 analyzed the traditionally-monstersaurian fossil taxa along with the rest of the dataset, and what it found was a well- ...

Albian
The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan '' Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined as the place where the foram species '' Rotalipora globotruncanoides'' first appears in the stratigraphic column.

Squamates
Squamata (, Latin ''squamatus'', 'scaly, having scales') is the largest order of reptiles, comprising lizards, snakes, and amphisbaenians (worm lizards), which are collectively known as squamates or scaled reptiles. With over 10,900 species, it is also the second-largest order of extant (living) vertebrates, after the perciform fish. Members of the order are distinguished by their skins, which bear horny scales or shields, and must periodically engage in molting. They also possess movable quadrate bones, making possible movement of the upper jaw relative to the neurocranium. This is particularly visible in snakes, which are able to open their mouths very wide to accommodate comparatively large prey. Squamata is the most variably sized order of reptiles, ranging from the dwarf gecko (''Sphaerodactylus ariasae'') to the Reticulated python (''Malayopython reticulatus'') and the now-extinct mosasaurs, which reached lengths over . Among other reptiles, squamates are most closely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dentary
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower tooth, teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed prenatal development, in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from ''wikt:mandere ...

Carinae
''Carinae'' was an area of ancient Rome. It was one of its most exclusive neighborhoods, where many of the senatorial class lived. Florus described the ''Carinae'' as the "''most celebrated part of the city''" (''celeberrima pars urbis''). Description The ''Carinae'' occupied the western end of the southern spur of the Esquiline hill in Rome. The district likely incorporated the earlier Fagutal, with the northern tip of the Oppian Hill on its western side; it extended between the Velian Hill and the ''Clivus Pullius''. Its outlook was southwestern, across the swamps of the ''Palus Ceroliae'' toward the Aventine. The slopes of the neighborhood near the Velia were crossed by the ''vicus Cyprius'', where, according to a Roman tradition taken up by Livy, Tullia would have killed his father Servius Tullius, overwhelming him with her chariot pulled by horses. The same passage from Livy indicates the existence of a temple dedicated to Diana in the ''Carinae''. The ''Murus Terreus ...

Anguimorpha
The Anguimorpha is a suborder of squamates. The group was named by Fürbringer in 1900 to include all autarchoglossans closer to '' Varanus'' and '' Anguis'' than ''Scincus ''Scincus'' is a genus of skinks, lizards in the family Scincidae. The genus contains four or five species, all of which are typical desert inhabitants, living in sandy and dune-like areas with a hot and dry climate. Species in the genus ''Scinc ...''. These lizards, along with iguanians and snakes, constitute the proposed "venom clade" Toxicofera of all venomous reptiles. Evolution The oldest widely accepted member of Anguimorpha is ''Dorsetisaurus'' from the Late Jurassic of Europe and North America. In 2022, the genus ''Cryptovaranoides'' was described from the latest Triassic (Rhaetian) of England. ''Cryptovaranoides'' was recovered in the study as a crown-group Anguimorph, and therefore the oldest crown group-squamate, 35 million years older than any previously known crown-group squamate.

Cretaceous Lizards
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 ...
