Chometokadmon
''Chometokadmon'' is an extinct genus of anguimorph lizard from the Early Cretaceous of Italy. The type and only species is ''Chometokadmon fitzingeri'', named by Italian zoologist Oronzio Gabriele Costa in 1864. It is known from only one specimen, a nearly complete skeleton from the comune of Pietraroja in the Apennine Mountains from the sediments of the Pietraroia Plattenkalk. Costa identified the specimen as a lizard, but in 1915 paleontologist Geremia d'Erasmo reclassified the skeleton as that of a rhynchocephalian on the basis of another rhynchocephalian specimen Costa had described, which d'Erasmo thought belonged to the same species. Later studies of the anatomy of these two specimens revealed that they belonged to two different species; Costa's ''Chometokadmon'' was a lizard whereas the other specimen, renamed ''Derasmosaurus'' in honor of d'Erasmo, was a rhynchocephalian. The first detailed description of ''Chometokadmon'' came in 2006, allowing it to be incorporated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Derasmosaurus
''Derasmosaurus'' is an extinct species of rhynchocephalian known from the Pietraroja Plattenkalk of Italy. It was originally considered to be a specimen of ''Lacerta brevicauda'' by Costa in 1866, it was later considered a specimen of the lizard '' Chometokadmon fitzingeri'' by D'Erasmo in 1915. It was described as a distinct rhynchocephalian genus in 1988. It is distinct from other indeterminate rhychocephalians found in the Plattenkalk. It is considered to be aquatically adapted, and possibly a member of the Pleurosauridae Pleurosauridae is an extinct family of sphenodontian reptiles, known from the Jurassic of Europe. Members of the family had long-snake like bodies with reduced limbs that were adapted for aquatic life in marine environments. It contains two gene ....

Pietraroja
Pietraroja is a mountain ''comune'' (municipality) in the province of Benevento in Campania, southern Italy. It is approximately 50 km by car from Benevento, in direction north-west, 83 km from Naples in direction north-east and approximately 223 km from Rome in direction south-east. Geography Pietraroja is the second ''comune'' by altitude (818 m above sea level) of the province; it is limited to north from the western side, oasis of natural protection, of mount Mutria (1,823 m) in the southern chain of the Matese mounts ( Apennines), to the border with comune of Guardiaregia in the region Molise. Its territory constitutes the high valley of the river Titerno, surrounded to north from Mutria and from Santa Crocella pass. Between these last two, in the place named "Tre Valloni", are the sources of the Titerno whose waters join with those of the torrent named "Acqua Calda" and, coasting along the buttress of Mount Mutria, they go down in the plain of Cusa ...

Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

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 ...

Varanoidea
Varanoidea is a superfamily of lizards, including the well-known family Varanidae (the monitors and goannas). Also included in the Varanoidea are the Lanthanotidae (earless monitor lizards), and the extinct Palaeovaranidae. Throughout their long evolutionary history, varanoids have exhibited great diversity, both in habitat and form. This superfamily includes the largest-known terrestrial lizard, Megalania (5–6 meters), and the largest extant lizard, the Komodo dragon (''Varanus komodoensis'', 3+ meters). Evolution Either synonymous with, or a subgroup of, the group Platynota, the varanoids first appear in the fossil record in the latter part of Early Cretaceous, but possible varanoid ancestors have been traced back as far as Early Jurassic times. Among the earliest known varanoids are the monitor-like necrosaurids '' Palaeosaniwa canadensis'' from the Campanian (roughly 71-82 mya) of North America and '' Estesia mongoliensis'' and '' Telmasaurus grangeri'', both from the Cam ...

Xenosauridae
Xenosauridae is a family of anguimorph lizards whose only living representative is the genus '' Xenosaurus'', which is native to Central America. Xenosauridae also includes the extinct genera '' Exostinus'' and '' Restes''. Also known as knob-scaled lizards, they have rounded, bumpy scales and osteoderms. Most living species prefer humid, rocky habitats, although they are widespread within their native regions, with some inhabiting semi-arid scrub environments. They are carnivorous or insectivorous, and give birth to live young. '' Shinisaurus'', the Chinese crocodile lizard, was once also regarded as a member of Xenosauridae, but most recent studies of the evolutionary relationships of anguimorphs consider ''Shinisaurus'' to be more closely related to monitor lizards and helodermatids than to ''Xenosaurus''. Xenosauridae is part of a larger clade A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, compose ...

Anguidae
Anguidae refers to a large and diverse family of lizards native to the Northern Hemisphere. Common characteristics of this group include a reduced supratemporal arch, striations on the medial faces of tooth crowns, osteoderms, and a lateral fold in the skin of most taxa. The group includes the slowworms, glass lizards, and alligator lizards, among others. The family is divided into two subfamilies (Anguinae and Gerrhonotinae), and contains about 87 species in 8 genera. Morphology and reproduction Anguids have hard osteoderms beneath their scales giving them an armored appearance. Many of the species have reduced or absent limbs, giving them a snake-like appearance, while others are fully limbed. Body type varies among species, with sizes ranging from 10 cm to 1.5 m. The group includes oviparous and viviparous species, both of which can be observed in a single genus at times. Feeding and habitat These lizards are known carnivorous or insectivorous foragers, feeding p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Phylogenetic Analysis
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does n ...
