Dwykia (named after the overlying Dwyka Group) is an extinct genus of prehistoric freshwater ray-finned fish that lived during the early Carboniferous period (Tournaisian age) in what is now South Africa. [1] It contains a single species, D. analensis from the Waaipoort Formation of the Upper Witteberg Series. [2] [3] It is one of a number of early fish genera long placed in the likely paraphyletic order Palaeonisciformes. [4]

Arthrodira is an order of extinct armored, jawed fishes of the class Placodermi that flourished in the Devonian period before their sudden extinction, surviving for about 50 million years and penetrating most marine ecological niches. Arthrodires were the largest and most diverse of all groups of placoderms.

Greererpeton burkemorani is an extinct genus of colosteid stem-tetrapods from the Early Carboniferous period of North America. Greererpeton was first described by famed vertebrate paleontologist Alfred S. Romer in 1969, based on a skull and partial skeleton from the Bluefield Formation. The skull was redescribed by Timothy R. Smithson in 1982, while postcranial remains were redescribed by Stephen J. Godfrey in 1989.

Eospinus daniltshenkoi is an extinct tetraodontid bony fish from the Eocene. Its fossils are from the Danata Formation lagerstatten of Ypresian Turkmenistan.

<i>Eoplectus</i> Extinct genus of fishes

Eoplectus is an extinct genus of prehistoric marine tetraodontiform fish that lived during the Eocene. It contains a single species, E. bloti from the Early Eocene-aged Monte Bolca site of Italy. It is the only member of the family Eoplectidae. It closely resembled pufferfishes and porcupinefishes, which it was related to.

Stolokrosuchus is an extinct genus of crocodyliforms that lived during the Early Cretaceous. Its fossils, including a skull with a long thin snout and bony knobs on the prefrontal, have been found in Niger. Stolokrosuchus was described in 2000 by Hans Larsson and Boubacar Gado. The type species is S. lapparenti. They initially described it as related to Peirosauridae, if not a member of that family. One study has shown it to be related to Elosuchus. However, more recent works usually find Stolokrosuchus to be one of the basalmost neosuchian, only distantly related to the elosuchid or pholidosaurid, Elosuchus. It was a semiaquatic crocodylomorph.

Cretatriacanthus is an extinct genus of prehistoric marine ray-finned fish from the Late Cretaceous. It contains a single species, C. guidottii from the late Campanian or early Maastrichtian of Nardò, Italy. It is generally placed as a basal tetraodontiform, although more recent studies have disputed this, finding it to instead represent an early basal percomorph.

The Witteberg or Witteberge is a South African mountain range just off the south-west corner of Lesotho. The range, which rises to 2408 metres, stretches for about 60 km (37 mi) from Lundin's Neck in the east to Lady Grey in the west. The range lends its name to the Witteberg Series, the uppermost fossiliferous sequence of the Cape System of sedimentary rocks in South Africa.

Camuropiscidae is a family of mostly small, bullet or spindle-shaped extinct arthrodire placoderms from the Late Devonian.

Clinus musaicus, the mosaic klipfish, is a species of bony fish from the family Clinidae, the kelp blennies. It is endemic to the waters off the Western Cape in South Africa where it occurs off the Cape Peninsula in False Bay on the Peninsula's eastern coast and the Atlantic Ocean off its western coast. All the specimens were collected from areas of flat, sandy substrates with scattered shell fragments.
