Pietraroja
Pietraroja is a mountain ''comune'' (municipality) in the province of Benevento in Campania, southern Italy. It is approximately 50 km by car from Benevento, in direction north-west, 83 km from Naples in direction north-east and approximately 223 km from Rome in direction south-east. Geography Pietraroja is the second ''comune'' by altitude (818 m above sea level) of the province; it is limited to north from the western side, oasis of natural protection, of mount Mutria (1,823 m) in the southern chain of the Matese mounts ( Apennines), to the border with comune of Guardiaregia in the region Molise. Its territory constitutes the high valley of the river Titerno, surrounded to north from Mutria and from Santa Crocella pass. Between these last two, in the place named "Tre Valloni", are the sources of the Titerno whose waters join with those of the torrent named "Acqua Calda" and, coasting along the buttress of Mount Mutria, they go down in the plain of Cusa ...

Macropenaeus
''Macropenaeus'' is an extinct genus of prawn in the order Decapoda, containing two species: the type species ''M. incertus'', known from the Late Cretaceous (Cenomanian) of Lebanon, and ''M. sidiaichensis'' known from the Early Cretaceous (Barremian) of Tunisia ) , image_map = Tunisia location (orthographic projection).svg , map_caption = Location of Tunisia in northern Africa , image_map2 = , capital = Tunis , largest_city = capital , .... The tail, segmented carapace, and long legs are clearly defined. The long, slender antennae are nicely displayed. The fossil dendrobranchiate shrimp ''Macropenaeus'' was originally described from the Upper Cretaceous (Cenomanian) limestones of Hadjoula, northwest Lebanon. A new species, ''M. sidiaichensis'' sp. nov., was recovered from the Sidi Aïch Formation in the Northern Chotts Range, southern Tunisia. The Barremian occurrence of the genus in Tunisia suggests that '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gonorynchiformes
The Gonorynchiformes are an order of ray-finned fish that includes the important food source, the milkfish (''Chanos chanos'', family Chanidae), and a number of lesser-known types, both marine and freshwater. The alternate spelling "Gonorhynchiformes", with an "h", is frequently seen but not official. Gonorynchiformes have small mouths and no teeth. They are the sole group in the clade Anotophysi, a subgroup of the superorder Ostariophysi. They are characterized by a primitive Weberian apparatus formed by the first three vertebrae and one or more cephalic ribs within the head. This apparatus is believed to be a hearing organ, and is found in a more advanced and complex form in the related cypriniform fish, such as carp. Also like the cypriniforms, the gonorynchiforms produce a substance from their skin when injured that dissolves into the water and acts an alarm signal to other fish. Taxonomy Although many of the families are rather small, there are several fossil genera. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Bonefishes
Albulidae is a family of fish, commonly known as the bonefishes, that are popular as game fish in Florida, select locations in the South Pacific and the Bahamas (where two bonefish are featured on the 10-cent coin) and elsewhere. The family is small, with 11 species in 3 genera.Hidaka, K., Tsukamoto, Y. & Iwatsuki, Y. (2016): ''Nemoossis'', a new genus for the eastern Atlantic long-fin bonefish ''Pterothrissus belloci'' Cadenat 1937 and a redescription of ''P. gissu'' Hilgendorf 1877 from the northwestern Pacific. ''Ichthyological Research, 64 (1): 45–53.'' Presently, the bonefishes are in their own order: Albuliformes . The families Halosauridae and Notacanthidae were previously classified in this order, but are now, according to FishBase, given their own order Notacanthiformes. The largest bonefish caught in the Western Hemisphere is a 16-pound, 3 ounce example caught off Islamorada, Florida, on March 19, 2007.

Aspidorhynchiformes
Aspidorhynchiformes (from New Latin "shield-snout forms") is an extinct order of ray-finned fish. It contains only a single family, the Aspidorhynchidae. Members of the group are noted for their elongated, conical rostrums, of varying length, formed from fused premaxillae. They are generally interpreted as stem-group teleosts. The range of the group extends from the Middle Jurassic to the late Paleocene. Taxonomic history The order was described by Pieter Bleeker in 1859. Aspidorhynchiformes has one family, which is divided into at least two genera: * Order †Aspidorhynchiformes Bleeker 1859 spidorhynchida; Aspidorhynchoidei Bleeker 1859** Family †Aspidorhynchidae Bleeker 1859 inctiferidae Silva Santos 1990; Diphyodontidae Jordan 1923*** Genus †'' Jonoichthys'' Gouiric-Cavalli 2015 *** Genus ?†'' Ophirachis'' Costa 1854 *** Genus †'' Platycerhynchus'' Costa 1864 *** Genus †'' Pseudovinctifer'' Arratia 2015 *** Genus †'' Richmondichthys'' Bartholomai 2004 *** Genu ...

Belonostomus
''Belonostomus'' (from el, βέλος , 'dart' and el, στόμα 'mouth') is a genus of prehistoric ray-finned fish that was described by Louis Agassiz in 1844. It is a member of the order Aspidorhynchiformes, a group of fish known for their distinctive elongated rostrums. The oldest known species are from the Upper Jurassic of Germany, with the youngest known species from the late Paleocene The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), E .... Fossils of ''Belonostmus'' have been found worldwide in marine deposits. It likely consumed plankton or other small fish.

Lepidotidae
Lepidotidae is an extinct family of fish, known from the Jurassic and Cretaceous periods. Most species were originally assigned to the genus ''Lepidotes'' which was long considered a wastebasket taxon. Cladistic analysis has indicated that they are close relatives of gars, with both being members of the order Lepisosteiformes. Members of the family are known from both marine and freshwater environments. ''Lepidotes sensu stricto'' had peg-like grasping marginal teeth and crushing palatal teeth, and is known to have consumed small crustaceans, while ''Scheenstia'' had low rounded crushing marginal teeth, indicating a durophagous diet.

Lepidotes
''Lepidotes'' (from el, λεπιδωτός , 'covered with scales') (previously known as ''Lepidotus'') is an extinct genus of Mesozoic ray-finned fish. It has been considered a wastebasket taxon, characterised by "general features, such as thick rhomboid scales and, for most of the species, by semi-tritorial or strongly with dozens of species assigned to it. Fossils attributed to ''Lepidotes'' have been found in Jurassic and Cretaceous rocks worldwide.López-Arbarello, A. (2012).Phylogenetic Interrelationships of Ginglymodian Fishes (Actinopterygii: Neopterygii). ''PLoS One'', 7(7): e39370. It has been argued that ''Lepidotes'' should be restricted to species closely related to the type species ''L. gigas,'' which are only known from the Early Jurassic of Central Europe, with most other species being not closely related, with other species transferred to new genera such as ''Scheenstia.'' ''Lepidotes'' belongs to Ginglymodi, a clade of fish whose only living representatives are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
