AntarctilamnaW
Antarctilamna

Antarctilamna is an extinct genus of Devonian shark originally exemplified by Antarctilamna prisca from South Eastern Australia and Antarctica. The latest occurring described species is Antarctilamna ultima from the Waterloo Farm lagerstätte in South Africa. Antarctilamna has robust ctenacanthid-like spines which lack a deep insertion area, and are borne in front of the first dorsal fin; in addition to distinctive diplodont teeth with small intermediate cusps. Antarctilamna-like spines, known from the Bunga Beds locality in Australia have been ascribed to A. Prisca.

ArganodusW
Arganodus

Arganodus is an extinct genus of Ceratodontidae (lungfish). Its fossils have been found in the Redonda Formation, New Mexico, the Tacuarembó Formation of Uruguay, and the Cumnock Formation, North Carolina, although the North Carolinian specimens are smaller than most recorded specimens. Fossils have also been uncovered in the Petrified Forest National Park. It was first named by Martin in 1979, and contains two species, A. dorotheae and A. atlantis. Arganodus was probably similar to modern lungfish, and lived in underwater burrows during dry periods until monsoons occurred.

Fossils have been found in marine sediments of France, England, and Germany, and in Early Cretaceous sediments of Brazil and Bornholm, Denmark. Isolated scales from the Bahariya Formation have been attributed to Lepidotes. In 1895, many species were assigned to it by Arthur Smith Woodward. They include, L. elvensis, L. semiserratus, L. tuberculatus, L. gallineki, L. leedsi, L. latifrons, L. haydeni, L. occidentalis, L. macrocheirus, L. subovatus, L. minor, L. affinis, L. unguiculatus, L. laevis, L. maximus, L. mantelli, L. degenhardti, L. hauchecorni, L. mawsoni, L. notopterus and L.? pustulatus. Numerous additional species have been assigned to it which Woodward considered indistinguishable from others. 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 tritorial dentition."

Mawsonia (fish)W
Mawsonia (fish)

Mawsonia is an extinct genus of prehistoric coelacanth fish, and the largest of this group, ranging from an estimated 3.5 metres up to 6.3 metres long. It lived during the Cretaceous period. Fossils have been found in the Bahia Group, Romualdo, Alcântara and Missão Velha Formations of Brazil, South America, as well as the Continental Intercalaire of Algeria and Tunisia, the Ain el Guettar Formation of Tunisia, and the Babouri Figuil Basin of Cameroon, Africa. Mawsonia was first described by British palaeontology Arthur Smith Woodward in 1907. The type species is Mawsonia gigas, named and described in 1907. Numerous distinct species have been described since then. M. brasiliensis, M. libyca, M. minor, and M. ubangiensis have all been proposed to be synonyms of M. gigas, although Léo Fragoso's 2014 thesis on mawsoniids finds M. brasiliensis valid and cautions against synonymizing M. minor without further examination. Several recent publications consider M. brasiliensis to be valid as well. Although initially considered to belong to this genus, "Mawsonia" lavocati is most likely referable to Axelrodichthys instead.

MegalolamnaW
Megalolamna

Megalolamna is an extinct genus of lamniform shark that belongs to the family Otodontidae. Its name comes from the similarity of its teeth to those of the extant shark genus Lamna. It is known from the early Miocene Chilcatay Formation of Peru, Oi and O'oshimojo Formations of Japan, and the Jewett Sand Formation of California and Pungo River Formation, North Carolina in the United States, implying a cosmopolitan distribution. It is considered to be the sister genus of Otodus. The study of Megalolamna's taxonomic relationships also demonstrates the possibility that Otodus needs to include the species sometimes assigned to Carcharocles in order to be monophyletic.

MeneW
Mene

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.

Mene purdyiW
Mene purdyi

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).

Otodus chubutensisW
Otodus chubutensis

Otodus chubutensis, meaning "ear-shaped tooth of Chubut", from Ancient Greek ὠτ and ὀδούς – thus, "ear-shaped tooth", is an extinct species of prehistoric megatoothed sharks in the genus Otodus, that lived during Oligocene, Miocene, and Pliocene epochs, approximately 28 – 5 million years ago. This shark is considered to be a close relative of the famous prehistoric megatoothed shark, O. megalodon. However, as is the case with O. megalodon, the classification of this species is disputed.

SphenacanthusW
Sphenacanthus

Sphenacanthus is an extinct genus of a chondrichtyan xenacanthiform that belongs to the Sphenacanthidae family and lived from the Late Devonian, through Carboniferous until the Late Permian period in Scotland, Spain, Russia and Brazil. It lived 359 million years ago, and probably it was one of the first member of the elasmobranchians, the lineage that leads to the modern sharks. Sphenacanthus probably hunts small fishes and, unlike their modern-day relatives, its inhabited fresh water lagoons. Sphenacanthus had seven fins, two in the upper part and five in the underside, and it have a heterodont dentition and mandibles relatively long and deeper. Sphenacanthus serrulatus is still only known from incomplete neurocranial remains and associated dermal material. These suggest that it was a relatively large shark,probably well over one meter in length when fully grown. Its body form was probably similar to that of other phalacanthous sharks.
