Pontosaurus Kornhuberi Skull 34
''Pontosaurus'' is a now extinct genus of Pythonomorpha, pythonomorph from the Late Cretaceous period. It was originally named ''Hydrosaurus'', but that name was Homonym (biology), preoccupied by an agamid lizard, so it was renamed. It is known from two species, both Cenomanian in age, the type ''P. lesinensis'' which is known from Hvar in Croatia, the other ''P. kornhuberi'' is known from the Sannine Formation in Lebanon. Both species were relatively small. ''P. krohuberi'' reached in length and in body mass, while ''P. lesinensis'' reached in length and in body mass.

Dragutin Gorjanović-Kramberger
Dragutin Gorjanović-Kramberger (born October 25, 1856 in Zagreb, died December 24, 1936, Zagreb) was a Croatian geologist, paleontologist, and archeologist. Education Dragutin finished his elementary education in Zagreb, Croatia, as well as two years of ''preparandija'' ( Faculty of Teacher Education, University of Zagreb). He started studying paleontology in Zürich, Switzerland. Soon, he moved to München, where his lecturer was Karl Zittel, a world-renowned expert in the areas of anatomy and paleontology. He received a doctoral degree in 1879, (Tübingen, Germany), with work related to fossilized fishes. From 1880, he was curator at the Mineralogical Department of the Croatian National Museum (today the Croatian Natural History Museum) and, in collaboration with his superior, archaeologist Đuro Pilar, he started mapping Mount Medvednica, (medvjed = bear, in Croatian), a mountain just north of Zagreb. In 1890 he changed his family name to Gorjanović. Lecturing His ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Pythonomorpha
Pythonomorpha was originally proposed by paleontologist Edward Drinker Cope (1869) as a reptilian order comprising mosasaurs, which he believed to be close relatives of Ophidia (snakes). The etymology of the term Pythonomorpha comes from the Greek ''Python'' (a monstrous snake from Greek mythology) and ''morphe'' ("form"), and refers to the generally serpentine body plan of members of the group. Cope wrote, "In the mosasauroids, we almost realize the fictions of snake-like dragons and sea-serpents, in which men have been ever prone to indulge. On account of the ophidian part of their affinities, I have called this order Pythonomorpha." Cope incorporated two families, the Clidastidae (now defunct but including only ''Clidastes'') and the Mosasauridae (including ''Macrosaurus'' Tylosaurus.html"_;"title="=Tylosaurus">''Tylosaurus''_''Mosasaurus.html" ;"title="Tylosaurus">''Tylosaurus''.html" ;"title="Tylosaurus.html" ;"title="=Tylosaurus">''Tylosaurus''">Tylosaurus.html" ;"title="=Ty ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homonym (biology)
In biology, a homonym is a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon. The rule in the International Code of Zoological Nomenclature is that the first such name to be published is the senior homonym and is to be used (it is " valid"); any others are junior homonyms and must be replaced with new names. It is, however, possible that if a senior homonym is archaic, and not in "prevailing usage," it may be declared a ''nomen oblitum'' and rendered unavailable, while the junior homonym is preserved as a ''nomen protectum''. :For example: :* Cuvier proposed the genus ''Echidna'' in 1797 for the spiny anteater. :*However, Forster had already published the name ''Echidna'' in 1777 for a genus of moray eels. :*Forster's use thus has priority, with Cuvier's being a junior homonym. :*Illiger published the replacement name ''Tachyglossus'' in 1811. Similarly, the International Code of Nomenclature for algae, fungi, and plants ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agamid
Agamidae is a family of over 300 species of iguanian lizards indigenous to Africa, Asia, Australia, and a few in Southern Europe. Many species are commonly called dragons or dragon lizards. Overview Phylogenetically, they may be sister to the Iguanidae, and have a similar appearance. Agamids usually have well-developed, strong legs. Their tails cannot be shed and regenerated like those of geckos (and several other families such as skinks), though a certain amount of regeneration is observed in some. Many agamid species are capable of limited change of their colours to regulate their body temperature. In some species, males are more brightly coloured than females, and colours play a part in signaling and reproductive behaviours. Although agamids generally inhabit warm environments, ranging from hot deserts to tropical rainforests, at least one species, the mountain dragon, is found in cooler regions. They are particularly diverse in Australia. This group of lizards includes som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hvar
Hvar (; Chakavian: ''Hvor'' or ''For'', el, Φάρος, Pharos, la, Pharia, it, Lesina) is a Croatian island in the Adriatic Sea, located off the Dalmatian coast, lying between the islands of Brač, Vis and Korčula. Approximately long, with a high east–west ridge of Mesozoic limestone and dolomite, the island of Hvar is unusual in the area for having a large fertile coastal plain, and fresh water springs. Its hillsides are covered in pine forests, with vineyards, olive groves, fruit orchards and lavender fields in the agricultural areas. The climate is characterized by mild winters, and warm summers with many hours of sunshine. The island has 10,739 residents according to the 2021 census, making it the 4th most populated of the Croatian islands. Hvar's location at the centre of the Adriatic sailing routes has long made this island an important base for commanding trade up and down the Adriatic, across to Italy and throughout the wider Mediterranean. It has been inhabite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sannine Formation
The Sannine Formation, also called the Sannine Limestone, is a Cretaceous geologic formation in Lebanon. Description It is primarily Cenomanian in age. The formation laterally varies from east to west; the western lowland "coastal" sequence is over 2000 metres thick and primarily consists of deep water limestone and chalk, while the eastern "mountain" sequence is 500–700 metres thick and consists of shallow water limestone. Pterosaur fossils have been recovered from the formation, including those of ''Mimodactylus'' and ''Microtuban''. The pythonomorphs '' Pontosaurus, Eupodophis'' and probably '' Aphanizocnemus'' are known from the formation. Insects are also known from compression fossils, including those of a dragonfly, enigmatic pond-skater like insect '' Chresmoda.'' and a mesoblattinid cockroach.P. Vršanský and E.

List Of Mosasaurs
This list of mosasaurs is a comprehensive listing of all genera that have ever been included in the family Mosasauridae or the parent clade Mosasauroidea, excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (''nomen dubium''), or were not formally published (''nomen nudum''), as well as junior synonyms of more established names, and genera that are no longer considered mosasauroid. Non-mosasaurid mosasauroids shall be noted as such. The list currently includes 85 genera, out of which 51 are considered valid (41 mosasaurids and 10 other mosasauroids). Scope and terminology There is no official, canonical list of mosasaur genera but one of the most thorough attempts can be found on th"Pythonomorpha" section of Mikko Haaramo's Phylogeny Archive Naming conventions and terminology follow the International Code of Zoological Nomenclature.
