Fultodromia is a genus of crabs within the family Dromiidae, with 2 species currently assigned to the genus. [1] [2] [3]
Galeocerdo is a genus of ground shark. Only a single species, G. cuvier, the tiger shark is extant. The earliest fossils date back to the early Eocene epoch, (Ypresian), around 56–47.8 Million years ago. While historically considered a member of the requiem shark family Carcharhinidae, it is currently considered to be the only member of the family Galeocerdonidae. While this genus was historically considered diverse, including 21 extinct species, morphometric analysis conducted in 2021 suggested that the diversity of the genus included only 5 extinct species much lower than previously assumed. The oldest fossils of the extant G. cuvier date to the middle Miocene.
The Phrynosomatidae are a diverse family of lizards, sometimes classified as a subfamily (Phrynosomatinae), found from Panama to the extreme south of Canada. Many members of the group are adapted to life in hot, sandy deserts, although the spiny lizards prefer rocky deserts or even relatively moist forest edges, and the short-horned lizard lives in prairie or sagebrush environments. The group includes both egg-laying and viviparous species, with the latter being more common in species living at high elevations.
Natrix is a genus of Old World snakes found mainly across Eurasia in the subfamily Natricinae of the family Colubridae. They are commonly called grass snakes and water snakes, but some other snake species also known commonly as "grass snakes" and "water snakes" are not in the genus.
Necturus is a genus of aquatic salamanders in the family Proteidae. Species of the genus are native to the eastern United States and Canada. They are commonly known as waterdogs and mudpuppies. The common mudpuppy (N. maculosus) is probably the best-known species – as an amphibian with gill slits, it is often dissected in comparative anatomy classes. The common mudpuppy has the largest distribution of any fully aquatic salamander in North America.
Lissemys is a genus of softshell turtles in the subfamily Cyclanorbinae of the family Trionychidae. The genus is indigenous to southern Asia.
Latimeriidae is the only extant family of coelacanths, an ancient lineage of lobe-finned fish. It contains two extant species in the genus Latimeria, found in deep waters off the coasts of southern Africa and east-central Indonesia. In addition, several fossil genera are known from the Mesozoic of Europe, the Middle East, and the southeastern United States, dating back to the Triassic.
Scolopendridae is a family of large centipedes.
Cycloderma is a genus of softshell turtles in the subfamily Cyclanorbinae of the family Trionychidae. The genus is endemic to Africa.
Epihippus is an extinct genus of the modern horse family Equidae that lived in the Eocene, from 46 to 38 million years ago.
Carditidae is a family of marine bivalve clams of the order Carditida, which was long included in the Venerida. They are the type taxon of the superfamily Carditoidea.
Chelonoidis is a genus of turtles in the tortoise family erected by Leopold Fitzinger in 1835. They are found in South America and the Galápagos Islands, and formerly had a wide distribution in the West Indies.
Baenidae is an extinct family of paracryptodiran turtles known from the Early Cretaceous to Eocene of North America. While during the Early Cretaceous they are found across North America, during the Late Cretaceous they are only found in Laramidia, having disappeared from Appalachia. The majority of lineages survived the K-Pg Extinction, but the family was extinct by the latest Eocene. The name of the type genus, Baena, appears to be of Native American origin. They are primarily found in freshwater deposits, and are considered to be aquatic, with a largely generalist habit.
Leptomithrax is a genus of crabs in the family Majidae, first described by Edward J. Miers in 1876. They have been on Earth for 37.2 million years.
Sphodrosaurus is an extinct genus of basal archosauriformn reptiles from the Late Triassic-aged New Oxford Formation of Pennsylvania. The type species is S. pennsylvanicus, described by Edwin Colbert in 1960. The holotype consists of a partial skeleton including the back of the skull, the vertebral column, all of the ribs, all of the hindlimbs and part of the upper forelimbs; Sphodrosaurus was originally believed to have been a member of the Procolophonidae while more recently Sphodrosaurus was believed to be a basal member of the Diapsida by most authors starting with Sues et al. (1993), or a member of the Rhynchosauria. In 2022, Ezcurra & Sues redescribed the holotype in detail and placed it in a phylogenetic analysis with other Triassic diapsid reptiles, where it was found as the basalmost doswellid.
Thanatosdrakon is a genus of quetzalcoatline azhdarchid pterosaur from the Late Cretaceous Plottier Formation of the Neuquén Basin in western Argentina. The genus name is derived from the Greek words thanatos (=death) and drakon (=dragon), while the specific name is a Quechuan word meaning "flying serpent" and refers to the Incan deity Amaru. The type and only species is Thanatosdrakon amaru, known from two specimens consisting of several well-preserved axial and appendicular bones including material previously undescribed in giant azhdarchids. Thanatosdrakon is one of the oldest known members of the Quetzalcoatlinae. T. amaru lived from about 90 to 86 million years ago.
Proterotherium is an extinct genus of litoptern mammal of the family Proterotheriidae that lived during the Late Miocene of Argentina and Chile. Fossils of this genus have been found in the Ituzaingó Formation of Argentina, and the Galera Formation of Chile.
Promacrauchenia is an extinct genus of macraucheniids that lived during the Late Miocene to Late Pliocene epochs of what is now Argentina and Bolivia. It belongs to the subfamily Macraucheniinae, which also includes Huayqueriana, Macrauchenia, and Xenorhinotherium. Fossils of this genus have been found in the Ituzaingó, Andalhuala, and Cerro Azul Formations of Argentina.
Austrodromidia is a genus of crabs within the family Dromiidae. There are currently 5 species designated to the genus, with the type species being Austrodromidia australis.
Epigodromia is a genus of crabs within the family Dromiidae, that first appeared during the Holocene epoch.
Anthemiphyllia is a genus of corals within the family Anthemiphylliidae. There are currently 8 extant and 2 extinct species assigned to the genus.
