Koumpiodontosuchus Aprosdokiti
''Koumpiodontosuchus'' is an extinct genus of neosuchian crocodyliform that lived in the Early Cretaceous. The only species is ''K. aprosdokiti'', named in 2015. Discovery The first fossilised fragment of a skull was discovered by Diane Trevarthen on a beach near Sandown in the Isle of Wight in March 2011. Three months later, the second fragment of the skull was found by Austin and Finley Nathan. The two fragments were donated to Dinosaur Isle. Megan Jacobs also discovered an isolated tooth belonging to the same genus that were twice the size of those from the holotype. The species that the fragments belonged to was named ''Koumpiodontosuchus aprosdokiti'', meaning "unexpected button-toothed crocodile". When the fragments were first seen by Steve Sweetman, a palaeontologist with the University of Portsmouth, he thought that they belonged to the ''Bernissartia fagesii'' species because of its small size and button-shaped teeth. Sweetman published a paper on the discovery of the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barremian
The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 129.4 ± 1.5 Ma (million years ago) and 121.4 ± 1.0 Ma). It is a subdivision of the Early Cretaceous Epoch (or Lower Cretaceous Series). It is preceded by the Hauterivian and followed by the Aptian Stage.See Gradstein ''et al.'' (2004) or the online geowhen database (link below) Stratigraphic definitions The original type locality for the Barremian Stage is in the vicinity of the village of Barrême, Alpes-de-Haute-Provence, France. Henri Coquand defined the stage and named it in 1873. The base of the Barremian is determined by the first appearance of the ammonites ''Spitidiscus hugii'' and ''Spitidiscus vandeckii''. The end of the Barremian is determined by the geomagnetic reversal at the start of the M0r chronozone, which is biologically near the first appearance of the ammonite '' Paradeshayesites oglanlensis''. Regional equivalents The Barremian falls in the Gallic epoch, a su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Neosuchian
Neosuchia is a clade within Mesoeucrocodylia that includes all modern extant crocodilians and their closest fossil relatives. It is defined as the most inclusive clade containing all crocodylomorphs more closely related to ''Crocodylus niloticus'' (the Nile Crocodile) than to ''Notosuchus terrestris''. Members of Neosuchia generally share a crocodilian-like bodyform adapted to freshwater aquatic life, as opposed to the terrestrial habits of more basal crocodylomorph groups. The earliest neosuchian is suggested to be the Early Jurassic ''Calsoyasuchus'', which lived during the Sinemurian and Pliensbachian stages in North America. It is often identified as a member of Goniopholididae, though this is disputed, and the taxon may lie outside Neosuchia, which places the earliest records of the group in the Middle Jurassic. Characteristics A tooth notch between the maxilla and premaxilla is a basal characteristic of the Neosuchia, although it is lost in some more derived forms, most nota ...

Crocodyliform
Crocodyliformes is a clade of crurotarsan archosaurs, the group often traditionally referred to as "crocodilians". They are the first members of Crocodylomorpha to possess many of the features that define later relatives. They are the only pseudosuchians to survive the K-Pg extinction event. In 1988, Michael J. Benton and James M. Clark argued that all traditional names for well-known groups of animals should be restricted to their crown clades, that is, used only for natural groups comprising all living members of any given lineage. This posed a problem for the crocodilians, because the name Crocodylia, while used in various ways by various scientists, had always included not only living crocodilians but many of their extinct ancestors known only from the fossil record.Benton, M.J. and Clark, J.M.

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 ...

Dinosaur Isle
Dinosaur Isle is a purpose-built dinosaur museum located in Sandown on the Isle of Wight in southern England. The museum was designed by Isle of Wight architect Rainey Petrie Johns in the shape of a giant pterosaur. It claims to be the first custom-built dinosaur museum in Europe. History Throughout the 19th century, many collectors such as the Reverend William Fox (1813-1881) excavated the types of new dinosaur genera, including ''Aristosuchus'', ''Hypsilophodon foxii'', and ''Polacanthus''. Most of the discoveries were then transferred to the mainland for study and exhibition, which after some time prompted the Isle of Wight Council to begin its own collection. In 1923 the Isle of Wight's first geological museum opened in Sandown, under the name of the "Museum of Isle of Wight Geology". The £2.7 million cost of Dinosaur Isle, the new museum, was provided by Isle of Wight Council and the National Lottery Millennium Commission. Dinosaur Isle opened to visitors on 10 Augu ...

Bernissartia Fagesii
''Bernissartia'' ('of Bernissart') is an extinct genus of neosuchian crocodyliform that lived in the Early Cretaceous, around 130 million years ago. At only in length, ''Bernissartia'' is one of the smallest crocodyliforms that ever lived. It resembled modern species in many respects, and was probably semi-aquatic. It had long, pointed teeth at the front of the jaws that would have been of use in catching fish, but broad and flat teeth at the back of its jaws that were suited for crushing hard food, such as shellfish, and possibly bones. It is known primarily from skulls and skeletons found in the Sainte-Barbe Clays Formation of Belgium and the Camarillas Formation of Spain. Less complete material has been referred to ''Bernissartia'' from the United Kingdom and North America.
