List Of Prehistoric Cartilaginous Fish (Chondrichthyes)
This list of prehistoric cartilaginous fish genera is an attempt to create a comprehensive listing of all genera that have ever been included in the class chondrichthyes ''and'' are known from the fossil record. This list excludes purely vernacular terms, genera that are now considered invalid, doubtful (nomina dubia), or were not formally published (nomina nuda), as well as junior synonyms of more established names, and genera that are no longer considered to be cartilaginous fish. It includes all commonly accepted genera. This list currently contains 804 generic names. * Extinct genera are marked by a dagger (†). * Extant taxon genera are bolded. Naming conventions and terminology Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include: * Junior synonym: A name which describes the same taxon as a previously published name. If two or more genera are formally designated and the type specimens are later assign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora And Fauna Of The Maastrichtian Stage
This is an incomplete list that briefly describes vertebrates that were extant during the Maastrichtian, a stage of the Late Cretaceous Period which extended from 72.1 to 66 million years before present.

Cretaceous Cartilaginous Fish
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 t ...

Prehistoric Cartilaginous Fish Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intertrappean Beds Formation
The Intertrappean Beds are a Late Cretaceous geologic formation in India. The beds are found as interbeds between Deccan Traps layers. Indeterminate theropod and pterosaur remains have been recovered from the formation, as well as dinosaur eggs.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. The mammal genera ''Deccanolestes'', ''Sahnitherium'', ''Bharattherium'', and'' Kharmerungulatum'' have been recovered from it as well. A rich plant flora is known from the formation.

Fatehgarh Formation
Fatehgarh is a cantonment town in Farrukhabad district in the state of Uttar Pradesh, India. It is located on the south bank of the Ganges River. It is the administrative headquarters of Farrukhabad District. Fatehgarh derives its name from an old fort. It is a small city with no significant industrial activity. Asia's largest potato market is located in Farrukhabad, as well as a holy place in buddhism (sankhisha). It contains a large Indian Army establishment in the form of The Rajput Regimental Centre, 114 Infantry Battalion TA and The Sikh Light Infantry Center. Demographics As per provisional data of 2011 census, Farrukhabad-cum-Fategarh urban agglomeration had a population of 290,540, out of which males were 154,630 and females were 135,910. The literacy rate was 75.60 per cent. India census, Fatehgarh had a population of 14,682. Males constitute 60% of the population and females 40%.

Lameta Formation
The Lameta Formation, also known as the Infratrappean Beds, is a sedimentary geological formation found in Madhya Pradesh, Gujarat, and Maharashtra, India, associated with the Deccan Traps. It is of Maastrichtian age (Late Cretaceous), and is notable for its dinosaur fossils. Many dubious names have been created for isolated bones, but several genera of dinosaurs from these rocks are well-supported, including the titanosaur sauropod ''Isisaurus'' and the abelisaurs '' Indosaurus'', '' Indosuchus'', '' Laevisuchus'', and ''Rajasaurus''.Weishampel et al., 2004, pp.517-606 As well as mammals, snakes and other fossils. Lithology The formation is underlain by the Lower Cretaceous sedimentary "Upper Gondwana Sequence" also known as the Jabalpur Formation, and is overlain by the Deccan Traps basalt. The Lameta Formation is only exposed at the surface as small isolated outcrops associated with the Satpura Fault. The lithology of the formation, depending on the outcrop, consists of al ...

Maastrichtian
The Maastrichtian () is, in the ICS geologic timescale, the latest age (uppermost stage) of the Late Cretaceous Epoch or Upper Cretaceous Series, the Cretaceous Period or System, and of the Mesozoic Era or Erathem. It spanned the interval from . The Maastrichtian was preceded by the Campanian and succeeded by the Danian (part of the Paleogene and Paleocene). The Cretaceous–Paleogene extinction event (formerly known as the Cretaceous–Tertiary extinction event) occurred at the end of this age. In this mass extinction, many commonly recognized groups such as non-avian dinosaurs, plesiosaurs and mosasaurs, as well as many other lesser-known groups, died out. The cause of the extinction is most commonly linked to an asteroid about wide colliding with Earth, ending the Cretaceous. Stratigraphic definitions Definition The Maastrichtian was introduced into scientific literature by Belgian geologist André Hubert Dumont in 1849, after studying rock strata of the ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilateral symmetry, bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and th ...
