The moonfish of the genus Mene, the sole extant genus of the family Menidae, are disk-shaped fish which bear a vague resemblance to gourami, thanks to their thread-like pelvic fins. Today, the genus is represented only by Mene maculata of the Indo-Pacific, where it is a popular food fish, especially in the Philippines, where it is known as bilong-bilong, chabita, hiwas or tahas. [2]
As a genus, Mene has a long fossil history, with species found in marine sediments throughout the Cenozoic Era. The earliest accepted species, M. purdyi from the Paleocene of Peru, resemble later species, such as M. rhombea of the Monte Bolca lagerstätte, and even the living species, M. maculata. Experts remain undecided whether the Tunisian species, M. phosphatica is from the Lower Paleocene, thus making it older than M. purdyi, or whether it is from the Ypresian epoch of the Eocene. Almost all of the species are known primarily from the Paleogene; the Neogene record is rather sparse, if not totally nonexistent, with some otoliths found in Miocene strata, and no whole or even partial specimens known from Pliocene or Pleistocene strata.
Anatomical and recent molecular studies strongly suggest a relationship with the pomfrets, dolphinfishes, remoras and the jacks in the order Carangiformes. [3]
Neoplagiaulax is a mammal genus from the Paleocene of Europe and North America. In the case of the latter continent, there may possibly be some slightly earlier, Upper Cretaceous material too. It existed in the age immediately following the extinction of the last dinosaurs. This animal was a member of the extinct order Multituberculata, lying within the suborder Cimolodonta and family Neoplagiaulacidae.
Cernaysia is an extinct genus of mammal from the Paleocene of France and the United States. It existed in the age immediately following the extinction of the last dinosaurs. This animal was a member of the extinct order Multituberculata within the suborder Cimolodonta and family Neoplagiaulacidae.
Krauseia is an extinct genus of small mammal from the Paleocene of North America. It was a member of the extinct order Multituberculata and is within the suborder of Cimolodonta, family Neoplagiaulacidae. The genus was nemed by Vianey-Liaud M. in 1986, and has also partly been known under the name Parectypodus.
Xanclomys is a small mammal from the Paleocene of North America. It was a genus within the extinct order Multituberculata within the suborder Cimolodonta and family Neoplagiaulacidae.
Anconodon is an extinct genus of mammal from the Paleocene of North America, and thus lived just after the "age of the dinosaurs". It was a member of the extinct order Multituberculata within the suborder Cimolodonta and possibly the family Cimolodontidae.
Microcosmodon is a mammal genus from the Paleocene of North America. It was a member of the extinct order Multituberculata, and lies within the suborder Cimolodonta and family Microcosmodontidae. The genus Microcosmodon was named by G.L. Jepsen in 1930.
The Gempylidae are a family of perciform fishes commonly known as snake mackerels or escolars. The family includes about 25 species.
Mene rhombea is an extinct perciform fish belonging to the family Menidae. During the Middle Eocene, about 48 to 40 mya, these fishes lived in the Tethys Ocean, a large tropical sea in the area corresponding to the current Mediterranean. This ocean was extended between the continents of Gondwana and Laurasia. At this time, where Monte Bolca is today, M. rhombea, and its relative, M. oblonga, lived in a tropical lagoon.
Mene purdyi an extinct species of ray-finned fish in the genus Mene, from Late Thanetian-aged marine deposits in northern Peru. M. purdyi is currently known only from a single skull and a few post-cranial bones. M. purdyi is among the largest, if not the largest, members of the genus, as the skull suggests that it would have been over 40 centimetres (16 in) in life. The living species, M. maculata, by comparison, grows to an average length of 18 centimetres (7.1 in).
Saccogaster is a genus of viviparous brotulas. They are found in the western Atlantic and Indo-Pacific.
Alectis is a genus of fish in the family Carangidae containing three extant species, all of which are large marine fishes. They are commonly known as threadfish, diamond trevallies or pompanos, although they have no close affiliation with the true pompano genus.
Hyposaurus is a genus of extinct marine dyrosaurid crocodyliform. Fossils have been found in Paleocene aged rocks of the Iullemmeden Basin in West Africa, Campanian–Maastrichtian Shendi Formation of Sudan and Maastrichtian through Danian strata in New Jersey, Alabama and South Carolina. Isolated teeth comparable to Hyposaurus have also been found in Thanetian strata of Virginia. It was related to Dyrosaurus. The priority of the species H. rogersii has been debated, however there is no sound basis for the recognition of more than one species from North America. The other North American species are therefore considered nomina vanum.
Bathysoma lutkeni is an extinct lamprid from the Danian age of Sweden, and is the second oldest lamprid known, after Nardovelifer of Campanian/Maastrichtian Italy. B. lutkeni has a disk-shaped body and an elongated head. It was originally described as a menid bony fish. Later, it was described as being a basal snake mackerel. Eventually, anatomical similarities with the Turkmenids were noted, and B. lutkeni is now regarded as an extremely basal lamprid.
Mene oblonga is a species of ray-finned fish that first appeared in the Monte Bolca Lagerstatten during the Lutetian epoch of the Eocene. For a menid, it has a very shallow body, especially in comparison with the sympatric Mene rhombea. Its fossils are very rare in Monte Bolca. A single fossil from the early Oligocene, referred to as "Mene oblonga var. pusilla," was found in Chiavon, Italy.
Caranx is a genus of tropical to subtropical marine fishes in the jack family Carangidae, commonly known as jacks, trevallies and kingfishes. They are moderate- to large-sized, deep-bodied fishes which are distinguished from other carangid genera by specific gill raker, fin ray and dentition characteristics. The genus is represented in the Pacific, Indian and Atlantic Oceans, inhabiting both inshore and offshore regions, ranging from estuaries and bays to deep reefs and offshore islands. All species are powerful predators, taking a variety of fish, crustaceans and cephalopods, while they in turn are prey to larger pelagic fishes and sharks. A number of fish in the genus have a reputation as powerful gamefish and are highly sought by anglers. They often make up high amounts of the catch in various fisheries, but are generally considered poor to fair table fishes.
Aturia is an extinct genus of Paleocene to Miocene nautilids within Aturiidae, a monotypic family, established by Campman in 1857 for Aturia Bronn, 1838, and is included in the superfamily Nautilaceae in Kümmel 1964.
Euzaphlegidae is a family of extinct escolar-like fish closely related to the snake mackerels. Fossils of euzaphlegids are found from Paleocene to Late Miocene-aged marine strata of Europe, the Caucasus Mountains, India, Iran, Turkmenistan, Italy, and Southern California.
Opsithrissops is an extinct genus of prehistoric bony fish that lived during the Thanetian stage of the Paleocene epoch. It is a 120 centimetres (3.9 ft) fish in the family Osteoglossiformes which includes other bony-tongues such as the extant species of Arowana and Arapaima.
Paleontology in North Carolina refers to paleontological research occurring within or conducted by people from the U. S. state of North Carolina. Fossils are common in North Carolina. According to author Rufus Johnson, "almost every major river and creek east of Interstate 95 has exposures where fossils can be found". The fossil record of North Carolina spans from Eocambrian remains that are 600 million years old, to the Pleistocene 10,000 years ago.
Mene maculata, the moonfish, is the only extant member of the genus Mene and of the family Menidae. The body is highly compressed laterally and very deep vertically. The ventral profile is steep, with a sharp ventral edge. The caudal (tail) fin is deeply forked. The mouth is small and protrusible. The body is silvery below and blue-green on the back, with three to four rows of dark gray spots on the upper side. The first two rays of the pelvic fin are greatly elongated, forming a prominent backward-pointing process on the underside of the fish.
