Eromangateuthis
''Eromangateuthis'' is an extinct genus of large plesioteuthidid cephalopod from the Cretaceous of Australia and possibly Canada. Description ''Eromangateuthis soniae'' is known from several gladii found in the Allaru Formation of Queensland and a potential gladius from the Northumberland Formation of British Columbia. It was originally described in 1993 as ''Boreopeltis soniae'', but was moved to its own genus in 2019 based on multiple differences between it and the type species of ''Boreopeltis''. The generic name is derived from the Eromanga Basin in which it was discovered and the Ancient Greek ''teuthís'' ( τευθίς, 'squid'). One gladius suggests it had a mantle A mantle is a piece of clothing, a type of cloak. Several other meanings are derived from that. Mantle may refer to: *Mantle (clothing), a cloak-like garment worn mainly by women as fashionable outerwear **Mantle (vesture), an Eastern Orthodox ve ... length of 1.2 meters.

Plesioteuthis
''Plesioteuthis'' is an extinct genus of squids, belonging to the family Plesioteuthididae. This genus was first described in 1859, and its fossils were found in the well-known Solnhofen field in Germany. Species Species within this genus include: *''Plesioteuthis prisca'' (the type species) (Rueppel, 1829) † *''Plesioteuthis subovata'' (G.G. Münster, 1846 ) † The ''Plesioteuthis arcuata'' is not considered a member of this genus. Together with its close relatives (including ''Rhomboteuthis'', ''Dorateuthis'' and ''Boreopeltis'') this animal has often been considered an archaic relative of the octopus (Octopodiformes) due to the fact that more than eight tentacles have never been found in fossils. However, the structure of the beak of Plesioteuthis resembles that of the Decapodiformes. Fossil record These squids lived in the Tithonian, Upper Jurassic (Age range from 155.7 to 150.8 million years ago) and their fossils were found in Germany.Sepkoski, JacSepkoski's Online G ...

Rhomboteuthis
''Rhomboteuthis'' is an extinct species of squid, with '' Rhomboteuthis lehmani'' currently being the only described member of the genus. ''Rhomboteuthis'' is known from during the Mid-Jurassic of Voulte-sur-Rhône, Ardèche, France France (), officially the French Republic ( ), is a country primarily located in Western Europe. It also comprises of overseas regions and territories in the Americas and the Atlantic, Pacific and Indian Oceans. Its metropolitan area .... References * Fischer, J.-C. & B. Riou 1982.

Extinction
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, dod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squid
True squid are molluscs with an elongated soft body, large eyes, eight arms, and two tentacles in the superorder Decapodiformes, though many other molluscs within the broader Neocoleoidea are also called squid despite not strictly fitting these criteria. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar role to teleost fish as open water predators of similar size and behaviour. They play an important role in the open water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swallowing. Squid are rapid swimmers, moving by jet propulsion, and largely locate their prey by sight. They are among the most intelligent o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric Cephalopod Families
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 Iron Age. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
