Mobulavermis () (meaning "Mobula worm") is an extinct genus of Cambrian kerygmachelid lobopodian from the Pioche Shale, the Combined Metals Member of the Pioche Formation in Nevada; USA. The type species is M. adustus, known from the holotype and paratype.

Manipulonyx is an extinct genus of alvarezsaurid theropod dinosaurs known from the Late Cretaceous (Maastrichtian age) Nemegt Formation of Mongolia. The genus contains a single species, Manipulonyx reshetovi, known from a partial skeleton. This includes the most complete forelimb known from any member of the alvarezsaurid subfamily Parvicursorinae, including all of the proximal bones. Manipulonyx has been interpreted as an ovivore (egg-eater), with unique ossified spikes on the wrist that helped the animal to grasp eggs and an enlarged claw on the functionally-monodactyl hand being used to pun

Chamaeleontiformes is a hypothesized clade (evolutionary grouping) of iguanian lizards defined as all taxa sharing a more recent common ancestor with Chamaeleo chamaeleon (the common chamaeleon) than with Hoplocercus spinosus (the Brazilian spiny-tailed lizard), Polychrus marmoratus (bush lizard), or Iguana iguana (green iguana). It was named by paleontologist Jack Conrad in 2008 to describe a clade recovered in his phylogenetic analysis that included the extinct genus Isodontosaurus, the extinct family Priscagamidae, and the living clade Acrodonta, which includes agamids and chameleons. It is

Baptanodon is an ichthyosaur of the Late Jurassic period (160-156 million years ago), named for its supposed lack of teeth (although teeth of this genus have since been discovered). It had a graceful long dolphin-shaped body, and its jaws were well adapted for catching squid. Major fossil finds of this genus have been recorded in North America. The type species, Sauranodon natans, was originally included under Sauranodon in 1879, but this name was preoccupied.

Vanescaves is a probable clade of strisorean birds that include the clades Steatornithiformes (the oilbird), Nyctibiiformes (the potoos), Podargiformes (frogmouths), and Apodimorphae (owlet-nightjars, swifts, and hummingbirds). Some molecular studies do support the grouping of these birds, others offer conflicting positions of the non-apodimorphaean strisoreans. In 2019 the authors Chen et al. performed a combined analysis using 2289 ultra-conserved elements [UCEs], 117 morphological characters from extant and fossil taxa found support in this clade. The authors then proposed to name this grou

Harpaginae is a subfamily of the bird of prey family Accipitridae. The species are found in Central and South America.

Heptamegacanthus is a genus of acanthocephalans (thorny-headed or spiny-headed parasitic worms) containing a single species, Heptamegacanthus niekerki, that is a parasite of the endangered giant golden mole. It is found only in isolated forests in the Transkei and near East London, both in South Africa. The worms are about 4 mm long and 2 mm wide with minimal sexual dimorphism. An individual's body consists of a short, wide trunk and a tubular feeding and sucking organ called the proboscis which is covered with hooks. The hooks are used to pierce and hold the rectal wall of its host.

The Phylloceratina are a suborder of ammonoid cephalopods, belonging to the Ammonitida, whose range extends from the Lower Triassic to the Upper Cretaceous. Shells of the Phylloceratina are generally smooth with small to large umbilici and complex sutures with leaf-like phylloid saddle endings and lobes with thornlike projections.

Aphaurosuchus is an extinct genus of baurusuchid mesoeucrocodylian known from the Late Cretaceous Bauru Basin of São Paulo, southern Brazil. It contains two species, Aphaurosuchus escharafacies and Aphaurosuchus kaiju.

Chromeornis (; ) is an extinct genus of longipterygid enantiornithean bird known from the Early Cretaceous (Aptian age) Jiufotang Formation of China. The genus contains a single species, Chromeornis funkyi, known from most of an articulated skeleton preserved on a slab and counterslab. This specimen was found with a mass of gastroliths in the esophagus, but these were likely not the gizzard stones expected in the gizzard of some birds. Instead, they may have been the result of an illness, with the animal dying after attempting to regurgitate them.

The kinglets or crests are small birds in the family Regulidae. Species in this family were formerly classified with the Old World warblers. "Regulidae" is derived from the Latin word regulus, diminutive for "king", and refers to the coloured crowns of adult birds. This family has representatives in Eurasia and North America. There are six species in this family; one, the Madeira firecrest (Regulus madeirensis), was only recently split from the common firecrest as a separate species. The ruby-crowned kinglet differs sufficiently in its voice and plumage to be afforded its own genus, Corthylio.

Saileriolidae is a family of true bugs and is considered a basal or "primitive" family within the stink bug lineage. They are found only in Asia. Originally included within the family Urostylididae, the group has recently been recognized as a separate family-rank lineage.

Medusavirus is a genus of nucleocytoplasmic large DNA viruses that is the sole representative of Mamonoviridae (from mamono (), the Japanese word for "monster" in reference to Megaviricetes + -viridae). It was first isolated from a Japanese hot spring in 2019. It notably encodes all five types of histones — H1, H2A, H2B, H3, and H4 — which are involved in DNA packaging in eukaryotes, raising the possibility that they may have been involved in the origin of eukaryotes. The virus can harden amoebae of the species Acanthamoeba castellanii into stone-like cysts, but infection usually causes infect

thumb | right Aethalodelphis is a genus of dolphins that was erected in 2025. The Pacific white-sided dolphin (Aethalodelphis obliquidens) and dusky dolphin (Aethalodelphis obscurus) are the only members of the genus. These species were formerly included in the genus Lagenorhynchus, but several studies demonstrated that Lagenorhynchus as previously constituted was polyphyletic. As a result, in 2025 the Pacific white-sided dolphin and dusky dolphin were reclassified into the new genus Aethalodelphis.

Propterodactylus (meaning "before Pterodactylus") is an extinct genus of transitional monofenestratan pterosaurs from the Late Jurassic Painten Formation of Germany. The genus contains a single species, P. frankerlae, known from a complete articulated skeleton. Before its naming, Propterodactylus was referred to as the "Painten " in the scientific literature.

Machimosauridae is an extinct family of teleosauroid thalattosuchian crocodyliforms. The family was first identified in 2016, when fossils of teleosauroid thalattosuchians, including an indeterminate close relative of Lemmysuchus and Machimosaurus, were described from the Middle Jurassic (Bathonian) of Morocco. The family was largely expanded in 2020 when the systematics of Teleosauroidea were re-reviewed. Members of this family generally were larger than the teleosaurids.

Maocyon ("dog from Maoming") is an extinct genus of hyaenodonts from extinct paraphyletic subfamily Hyainailourinae within paraphyletic family Hyainailouridae, that lived during the late Eocene in China. It is a monotypic genus that contains the species M. peregrinus.

Megalocnidae is an extinct family (alternatively considered to be a superfamily as Megalocnoidea) of sloths, native to the islands of the Greater Antilles from the Early Oligocene to the Mid-Holocene. They are known from Cuba, Hispaniola and Puerto Rico, but are absent from Jamaica. While they were formerly placed in the Megalonychidae alongside two-toed sloths and ground sloths like Megalonyx, recent mitochondrial DNA and collagen sequencing studies place them as the earliest diverging group basal to all other sloths. or as an outgroup to Megatherioidea. They displayed significant diversity i

Magnipterygius is an extinct genus of primitive ichthyosaur found in the Early Jurassic (Lower Toarcian) Posidonia Shale of Dotternhausen, Germany. The holotype specimen is SMNS96922, a nearly complete articulated skeleton. This genus is well known as a small-sized ichthyosaur, of around length, making it the second genus of that size after the Triassic. Due to the similarities with the genus Stenopterygius it has been classified as a member of the family Stenopterygiidae.

Ghatiana is a genus of freshwater crabs, found among the Western Ghats in India.

Erratus is an extinct genus of marine arthropod from the Cambrian of China. Its type and only species is Erratus sperare. Erratus is likely one of the most basal known arthropods, and its discovery has helped scientists understand the early evolution of arthropod trunk appendages. Some of the stem-arthropods like radiodonts did not have legs, instead they had flap like appendages that helped them swim. Erratus on the other hand had not only flaps but also a set of primitive legs. It also supported the theory that the gills of aquatic arthropods probably evolved into the wings and lungs of terr

Paleoanguimorpha is a clade of anguimorphs comprising Shinisauria (represented today by shinisaurids) and Goannasauria (represented today by Varanoidea which includes the families Lanthanotidae and Varanidae). Morphological studies in the past also classified helodermatids and pythonomorphs with the varanoids in the clade Platynota, while the Chinese crocodile lizard was classified as a xenosaurid. Current molecular work finds no support in these groupings and instead has found the helodermatids more related to Diploglossa in the sister clade Neoanguimorpha, while the Chinese crocodile lizard

Spathagnathus (meaning "spatula jaw") is a genus of ctenochasmatid pterosaur from the Late Jurassic Solnhofen Limestone of Germany. The type and only species is Spathagnathus roeperi, known from a single jawbone. It is the oldest known member of Gnathosaurinae, and the second pterosaur from the Solnhofen's Brunn quarry after the rhamphorhynchid Bellubrunnus. The unique dental anatomy of the taxon is thought to indicate a diet of tough, hard-shelled prey items.
