Sauripterus ("lizard wing") is a genus of rhizodont lobe-finned fish that lived during the Devonian period (416-360.7 Ma). [2] This genus was described by J. Hall after its discovery at Powy's Curve in Pennsylvania. [1]
The Cryptobranchidae are a family of fully aquatic salamanders commonly known as the giant salamanders. They include some of the largest living amphibians. The family is native to China, Japan, and the eastern United States. They constitute one of two living families—the other being the Asiatic salamanders belonging to the family Hynobiidae—within the Cryptobranchoidea, one of two main divisions of living salamanders.
The snowy egret is a small white heron. The genus name comes from Provençal French for the little egret, aigrette, which is a diminutive of aigron, 'heron'. The species name thula is the Araucano term for the black-necked swan, applied to this species in error by Chilean naturalist Juan Ignacio Molina in 1782.
Orcinus is a genus of Delphinidae, the family of carnivorous marine mammals known as dolphins. It includes the largest delphinid species, Orcinus orca, known as the orca or killer whale. Two extinct species are recognised, Orcinus paleorca and O. citoniensis, describing fossilised remains of the genus. The other extinct species O. meyeri is disputed.
Synaptomys is a genus of North American lemmings. These animals live in wet forested and open areas. They are small, cylindrical rodents with large heads and short ears, legs, and tails. They eat green vegetation such as grasses and sedges. They are often found in colonies.
Sand sharks, also known as sand tiger sharks, gray nurse sharks or ragged tooth sharks, are mackerel sharks of the family Odontaspididae. They are found worldwide in temperate and tropical waters. The three species are in two genera.
Cyclanorbis is a genus of softshell turtles in the family Trionychidae. The genus is endemic to Africa.
Ceramornis is a prehistoric bird genus from the Late Cretaceous. It lived shortly before the Cretaceous–Paleogene extinction event in the Maastrichtian, some 66 million years ago (mya). Its remains were found in the Lull 2 location, a Lance Formation site in Niobrara County, Wyoming. A single species is known, Ceramornis major, and even that only from a proximal piece of coracoid. This is specimen UCMP V53957, which was collected by a University of California team in 1958.
Ictidopappus is an extinct genus of mammals from extinct subfamily Ictidopappinae within extinct family Viverravidae, that lived in North America during the early Paleocene.
Hadrianus is an extinct genus of tortoise belonging to the Testudinidae found in the United States, the Yolomécatl Formation of Mexico, the Alai Beds of Kyrgyzstan and Spain and believed to be the oldest true tortoise known. The genus is thought to be closely related to the genus Manouria. The genus may have evolved in the subtropics of Asia and subsequently migrated to North America and Europe. Evangelos Vlachos (2018) reassessed the North American species attributed to the genus, and determined only two as accepted namely H. corsoni & H. majusculus. The remaining species were identified as either junior synonyms, moved to other genera or considered nomen dubium do to incomplete fossils.
Parietobalaena is an extinct genus of baleen whale, belonging to the family Pelocetidae. Fossils are found in Miocene-aged marine strata in North America, Europe, Australia, and Japan, including the Temblor and Itahashi formations. Based on previous estimates of juvenile specimens, Tsai (2017) suggested a body size of 12-15 m for P. yamaokai, akin to that of the gray whale.
Anodontites is a genus of freshwater mussels, aquatic bivalve mollusks in the family Mycetopodidae. Anodontites are present in South and Middle America, as far north as Mexico.
Phocageneus is an extinct genus of river dolphin belonging to Squalodelphinidae. Specimens have been found in the middle Miocene Calvert Formation of Maryland and Virginia.
Anevrina is a genus of phorid flies circumscribed by the Italian naturalist Paolo Lioy in 1864.
Boreostemma is an extinct genus of glyptodonts from northern South America. Fossils assigned to the genus were first described as belonging to Asterostemma from southern South America, but have been placed in the new genus Boreostemma by Carlini et al. in 2008. The type species is B. pliocena. Fossils of Boreostemma have been found in the Honda Group of Colombia, in Peru and Venezuela.
Peramus is an extinct genus of cladotherian mammal. It lived in the Late Jurassic and Early Cretaceous of Europe and North Africa.
Taphrosphys is an extinct genus of bothremydid pleurodiran turtle that was discovered Angola, Morocco and the United States. The genus consists of type species Platemys sulcatus, T. ippolitoi, T. congolensis, and the dubious T. dares.
Phosphatochelys is an extinct genus of bothremydid pleurodiran turtle that was discovered near Oued Zem, Morocco. The genus consists solely of type species P. tedfordi.
Labrostochelys is an extinct genus of bothremydid pleurodiran turtle that was discovered in the Ouled Abdoun Basin, Morocco. The genus consists solely of type species L. galkini.
Nigeremys is an extinct genus of bothremydid pleurodiran turtle from Niger, Mali and Syria. The genus consists exclusively of the combinatio nova of the type species N. gigantea.
