Gavialidae is a family of large semiaquatic crocodilians with elongated, narrow snouts. Gavialidae consists of two living species, the gharial and the false gharial, both occurring in Asia. Many extinct members are known from a broader range, including the recently extinct Hanyusuchus. Gavialids are generally regarded as lacking the jaw strength to capture the large mammalian prey favoured by crocodiles and alligators of similar size so their thin snout is best used to catch fish, however the false gharial has been found to have a generalist diet with mature adults preying upon larger vertebrates, such as ungulates.
Neurotrichus is a genus of shrew-like moles. It is classified, together with the fossil genus Quyania, in the tribe Neurotrichini of the subfamily Talpinae. The only living species is the American shrew-mole (N. gibbsii) of the northwestern United States and British Columbia. A fossil species, Neurotrichus columbianus from the Hemphillian of Oregon, was placed in the genus in 1968, but this animal is now thought to be more closely related to the Chinese fossil genus Yanshuella.
Kinnareemimus is a genus of ornithomimosaurian theropod dinosaur from Thailand. It is known only from incomplete remains discovered no later than the early 1990s that includes vertebrae, partial pubic bones, metatarsals, and an incomplete fibula. The third metatarsal exhibits a distinctive lateral "pinching", known as the "arctometarsalian" condition, variations of which are found in ornithomimosaurs, tyrannosauroids, troodontids, and caenagnathids. Its remains were collected from the Early Cretaceous Sao Khua Formation, dating to the Barremian stage, at Phu Wiang, Khon Kaen Province. Its early occurrence makes it among the earliest ornithomimosaur known, depending on the age of the formation. Buffetaut et al. suggest the fossils of Kinnareemimus may indicate an Asian origin for advanced ornithomimosaurs.
Haptodus is an extinct genus of basal sphenacodont, member of the clade that includes therapsids and hence, mammals. It was at least 1.5 metres (5 ft) in length. It lived in present-day France during the Early Permian. It was a medium-sized predator, feeding on insects and small vertebrates.
Scymnodon is a genus of squaliform sharks in the family Somniosidae.
Whalleyana is an enigmatic genus of moths in the lepidopteran group Obtectomera, endemic to Madagascar. The genus contains two species, whose biology are unknown. The genus had been placed in the picture-winged leaf moths, (Thyrididae), but then was placed in its own family, and later elevated to its own superfamily ; see also Fänger (2004). The genus was named after Paul E. S. Whalley, a British entomologist. Genomic studies have found them to be most closely related to Callidulidae, and it is suggested that they should be placed in Calliduloidea.
The western dwarf galagos are a group of three species of strepsirrhine primates, native to western and central Africa. They are classified in the genus Galagoides of the family Galagidae. The eastern dwarf galagos have been moved to their own genus, Paragalago, based on genetic evidence and differences in vocalization. The two genera are not sister taxa and thus may have evolved their small sizes via parallel evolution. They are separated by the East African Rift.
Urotrichus is a genus of talpid that contains a single living species, the Japanese shrew mole (Urotrichus talpoides). Two fossil species are also known.
Protuberum is an extinct genus of traversodontid cynodonts known from a single species Protuberum cabralense, from the Middle Triassic of Brazil.
Quasicaecilia is an extinct genus of microsaur. It is known from the Early Permian of Texas in the United States. A single specimen is known, collected from the Texas Permian redbeds by Charles Hazelius Sternberg in 1917. It was originally identified as a specimen of the gymnarthrid microsaur Cardiocephalus. The skull is small, less than 2 centimetres (0.79 in) in length, and the otic capsule is very large in comparison to the rest of the skull. The skull of Quasicaecilia superficially resembles those of extant but unrelated caecilians, hence the genus name. Quasicaecilia was assigned to the new family Brachystelechidae in 1991 along with the genera Batropetes and Carrolla.
Oligoryzomys rupestris is a species of rodent in the genus Oligoryzomys of family Cricetidae. It is known only from eastern Brazil, where it has been found in several localities in the campos rupestres montane savanna ecoregion. This is a small Oligoryzomys species with a gray head, a yellow-brown back and gray belly and tail. Of the two karyotypic forms described by Silva & Yonenaga-Yassuda in 1998, species 1 is probably identical to O. rupestris, while the other is closely related. Its karyotype has 2n = 46 and FNa = 52.
Hyloplesion is an extinct genus of microbrachomorph microsaur. It is the type and only genus within the family Hyloplesiontidae. Fossils have been found from the Czech Republic near the towns of Plzeň, Nýřany, and Třemošná, and date back to the Middle Pennsylvanian. The type species is H. longicostatum, named in 1883. Two species belonging to different genera, Seeleya pusilla and Orthocosta microscopica, have been synonymized with H. longicostatum and are thought to represent very immature individuals.
Brachystelechidae is an extinct family of Early Permian microsaurs. The family was first named by Robert L. Carroll and Pamela Gaskill in 1978, with the only member being Brachystelechus fritschi. Brachystelechus fritschi has since been reassigned to the genus Batropetes. Three genera are currently assigned to the family: Batropetes, from Germany; Carrolla, from Texas; and Quasicaecilia, also from Texas.
Tienosuchus is a dubious extinct monospecific genus of gavialoid crocodilian. It is known from a single tooth and some postcranial remains collected from Eocene deposits in Hunan, China. It is closely related to the genus Thoracosaurus, and has traditionally been placed in the subfamily Thoracosaurinae. The subfamily is now considered to be a paraphyletic assemblage of basal gavialoids, and therefore not a true clade. Because the fragmentary remains provide little diagnostic value, the genus is now considered a nomen dubium.
The Palmophyllales are a deep-branching order of thalloid green alga, containing the single family Palmophyllaceae. They possibly form a sister group to the Chlorophyta. They survive today in deep waters, where predation pressure is reduced. The group contains the genera Palmophyllum, Verdigellas and Palmoclathrus. The morphology of Palmophyllales is unusual in that they are composed of cells in a gelatinous matrix, so they are multicellular, but not in a conventional way.
Quasianosteosaurus is an extinct genus of basal ichthyosaur known from the late Early Triassic of Spitsbergen of the Svalbard archipelago, Norway. It was first named by Michael W. Maisch and Andreas T. Matzke in 2003 and the type species is Quasianosteosaurus vikinghoegdai. The generic name is derived from Latin quasi, "almost", and Greek anosteos, "boneless" and sauros, "lizard", regarding the preservation of the holotype which is almost exclusively a natural cast of the skull with very little original bone. The specific name is derived from Vikinghøgda, "Mount Viking", where the holotype was found. Quasianosteosaurus is known only from the holotype MNHN Nr. SVT 331, a partial three-dimensionally preserved skull consisting of the snout and orbital and postorbital regions. The skull is by far the largest Early Triassic ichthyosaur skull known, with an estimated cranial length of 50 cm (20 in). It was collected from the lowermost Grippia Niveau of the Sticky Keep Formation, Sassendalen Group at Mount Viking, Sassendalen. A phylogenetic analysis performed by Maisch & Matzke (2003) found it to be a basal ichthyosaur, sister taxon to Hueneosauria.
Human coronavirus 229E (HCoV-229E) is a species of coronavirus which infects humans and bats. It is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to the APN receptor. Along with Human coronavirus OC43, it is one of the viruses responsible for the common cold. HCoV-229E is a member of the genus Alphacoronavirus and subgenus Duvinacovirus.
The squirrel galagos are a group of four species of strepsirrhine primates. They are classified in the genus Sciurocheirus of the family Galagidae.
Tracheloraphis is a genus of ciliates in the family Trachelocercidae.
Mahuidacursor is a genus of basal ornithopod dinosaur from the Santonian Bajo de la Carpa Formation of the Neuquén Basin in northern Patagonia, Argentina. The type and only species is M. lipanglef.
