Cricosaurus Schroederi
''Enalioetes'' is an extinct genus of metriorhynchid thalattosuchian from the Early Cretaceous Stadthagen Formation of Germany. The type species is ''E. schroederi''. Prior to its description in 2024, it was known under the informal names ''Enaliosuchus'' "schroederi" and ''Cricosaurus'' "schroederi". Discovery and naming The holotype, which consists of much of the skull as well as parts of the neck, was discovered no later than 1916 in the Stadthagen Formation in Engelbostel, Germany. At the time of its discovery, the fossil material was thought to have belonged to a type of ichthyosaur by its discoverer, a government architect by the name of D. Hapke. Hapke then turned the fossils over to Prussian paleontologist Henry Schroeder in 1916, who proceeded to prepare and describe the material. Some years prior, in 1883, Ernst Koken described another metriorhynchid from the Stadthagen Formation, which he named ''Enaliosuchus macrospondylus''.Koken E. (1883). Die reptilian der nord ...

Early Cretaceous
The Early Cretaceous (geochronology, geochronological name) or the Lower Cretaceous (chronostratigraphy, chronostratigraphic name) is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 143.1 Megaannum#SI prefix multipliers, 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 Anoxic event#Cretaceous, early Aptian Oceanic Anoxic Event 1a (OAE1a) was 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 Plateau, Ontong Java-Manihiki Plateau, Manihiki-Hikurangi Plateau, Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Onto ...

International Code Of Zoological Nomenclature
The International Code of Zoological Nomenclature (ICZN) is a widely accepted Convention (norm), convention in zoology that rules the formal scientific name, scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its formal author, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules principally regulate: * How names are correctly established in the frame of Binomial nomenclature, binominal nomenclature * How to determine whether a given name is Available name, available * Which available name must be used in case of name conflicts (Valid name (zoology), valid name) * How scientific literature must cite names Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus ''Abronia (other), Abronia'' in both animals and plants). The rules and re ...

Cretaceous Crocodylomorphs
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . 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 largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic groups present in modern times can be ultimately traced back to origins in the C ...
