Caeus
''Caeus'' is an extinct genus of prehistoric marine ray-finned fish, closely related to the modern milkfish. It contains a single species, ''C. leopoldi'' from the Early Cretaceous of the Pietraroja Plattenkalk, Italy. It is one of the largest teleosts known from the Pietraroja formation, and is known by only a single specimen. It was first described as a genus without a species in 1857, before being officially described as a proper species in 1860. Some authorities have placed it as a species of the modern genus '' Chanos'', but further studies have affirmed it as being a distinct genus. It is thought to be phylogenetically intermediate between '' Parachanos'' and '' Dastilbe''. See also * Prehistoric fish * List of prehistoric bony fish A ''list'' is any set of items in a row.

Albian
The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan '' Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined as the place where the foram species '' Rotalipora globotruncanoides'' first appears in the stratigraphic column.

Fossils Of Italy
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Prehistoric Ray-finned 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 Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dastilbe
''Dastilbe'' is an extinct genus of prehistoric bony fish from the Aptian. Species * ''Dastilbe elongatus'' Silva Santos, 1947 * ''Dastilbe crandalli'' Jordan, 1910 Description ''Dastilbe'' could reach a length of , with a maximum length of about . It was probably an anadromous fish, tolerant of hypersalinity and subjected to frequent mass mortality. Larger individuals of this predatory fish fed on small fishes and probably they were also cannibalistic. Distribution ''Dastilbe'' was a primitive gonorynchiform fish widespread in Gondwanaland. Fossils of this fish have been found in the Aptian stage of the Lower Cretaceous Cabo, Codo and Crato Formations of northeastern Brazil and in the Lower Cretaceous of Africa. Taxonomy The type species ''Dastilbe crandalli'' was described by the American ichthyologist David Starr Jordan from specimens collected in Brazil, up to four species have been suggested as comprising ''Dastilbe'' but other authorities have suggested that t ...

Prehistoric Fish
The evolution of fish began about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates. The first fish lineages belong to the Agnatha, or jawless fish. Early examples include ''Haikouichthys''. During the late Cambrian, eel-like jawless fish called the conodonts, and small mostly armoured fish known as ostracoderms, first appeared. Most jawless fish are now extinct; but the extant lampreys may approximate ancient pre-jawed fish. Lampreys belong to the Cyclostomata, which includes the extant hagfish, and this group may have split early on from other agnathans. The earliest Gnathostomata, jawed vertebrates probably developed during the late Ordovician period. They are first represented in the fossil record from the Silurian by two groups of fish: the armoured fish known as Placodermi, placoderms, which evolved from the ostracoderms; and the ...

Oronzio Gabriele Costa
Oronzo Gabriele Costa (26 August 1787, Alessano – 7 November 1867 Naples) was an Italian zoologist. At first a physician, he taught zoology at the University of Naples. He wrote 126 papers on various subjects, principally entomology, and in 1846 served as president of the Accademia Pontaniana in Naples. His two sons, Achille Costa (1823-1899) and Giuseppe Costa, were also both well known zoologists. Publications There has been a good deal of confusion over the publication details of his most important work, the ''Fauna del Regno di Napoli'' (full title: ''Fauna del Regno di Napoli, ossia, enumerazione di tutti gli animali che abitano le diverse regioni di questo regno e le acque che le bagnano''), published over a long period of time, including posthumously, in collaboration with his son, Achille Costa. Taeger and Blank (1996; p. 253) state that for some of the work, Oronzio was merely the editor, Achille being the actual author, and whose name appears on the title pa ...
