Requiem Shark
Requiem sharks are sharks of the family Carcharhinidae in the order Carcharhiniformes. They are migratory, live-bearing sharks of warm seas (sometimes of brackish or fresh water) and include such species as the tiger shark, bull shark, lemon shark, spinner shark, blacknose shark, blacktip shark, grey reef shark, blacktip reef shark, silky shark, dusky shark, blue shark, copper shark, oceanic whitetip shark, and whitetip reef shark. Family members have the usual carcharhiniform characteristics. Their eyes are round, and one or two gill slits fall over the pectoral fin base. Most species are viviparous, the young being born fully developed. They vary widely in size, from as small as adult length in the Australian sharpnose shark, up to adult length in the tiger shark.Compagno, L.J.VFamily Carcharhinidae - Requiem sharksin Froese, R. and D.

Cretaceous
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 b ...

Valanginian
In the geologic timescale, the Valanginian is an age or stage of the Early or Lower Cretaceous. It spans between 139.8 ± 3.0 Ma and 132.9 ± 2.0 Ma (million years ago). The Valanginian Stage succeeds the Berriasian Stage of the Lower Cretaceous and precedes the Hauterivian Stage of the Lower Cretaceous. Stratigraphic definitions The Valanginian was first described and named by Édouard Desor in 1853. It is named after Valangin Valangin () is a former municipality in the district of Val-de-Ruz in the canton of Neuchâtel in Switzerland. On 1 January 2021 the former municipalities of Corcelles-Cormondrèche, Peseux and Valangin merged into the municipality of Neuchâ ..., a small town north of Neuchâtel in the Jura Mountains of Switzerland. The base of the Valanginian is at the first appearance of Calpionellidae, calpionellid species ''Calpionellites darderi'' in the stratigraphic column.

Languedoc
The Province of Languedoc (; , ; oc, Lengadòc ) is a former province of France. Most of its territory is now contained in the modern-day region of Occitanie in Southern France. Its capital city was Toulouse. It had an area of approximately 42,700 square kilometers (16,490 square miles). History The Roman province of Gallia Narbonensis fell to the Visigothic Kingdom from the 5th to the 8th centuries. Occupied briefly by the Emirate of Córdoba between 719 and 759, it was conquered and incorporated into the Kingdom of the Franks by Pippin the Short in 759 following the Siege of Narbonne. Under the Carolingians, the counts of Toulouse were appointed by the royal court. Later, this office became hereditary. Part of the territory where Occitan was spoken came to be called ''langue d'oc'', ''Lengadòc'' or Languedoc. In the 13th century, the spiritual beliefs of the area were challenged by the See of Rome and the region became attached to the Kingdom of France following the ...

It is also spoken in Calabria (Southern Italy) in a linguistic enclave of Cosenza area (mostly Guardia Piemontese). Some include Catalan language, Catalan in Occitan, as the Linguistic distance, distance between this language and some Occitan dialects (such as the Gascon language) is similar to the distance between different Occitan dialects.

Scoliodon
''Scoliodon'' is a genus of requiem sharks in the family Carcharhinidae. It was formerly thought to include only a single Indo-Pacific species, the spadenose shark (''S. laticaudus''), but recent taxonomic research has found an additional species, the Pacific spadenose shark (''S. macrorhynchos''). Location The ''Scoliodon'' genus of sharks has been found mainly in the Indo-West Pacific oceans from the west coasts of Africa to south of Japan. Biology ''Scoliodon'' has an elongated, spindle-shaped body tapered at the ends, making it a very fast swimmer. The trunk and tail are laterally compressed, while the head region is dorsoventrally compressed. The entire body is covered by an exoskeleton of placoid scales. The mouth is located on the ventral side and is bound on both sides by jaws. It has two rows of homodont or polyphyodont teeth, which are homologous to the placoid scales covering the body. Male ''Scoliodon'' species mature at a length of 33 cm while female ''Sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
