Anisacanthus Anisacanthus is a genus of flowering plants in the bear's breeches family, Acanthaceae. The generic name is derived from the Greek words ανισος ("anisos"), meaning "unequal," and ακανθος ("acanthos"), meaning "thorn." Members of the genus are native to tropical and subtropical regions of the Americas. They are commonly known as desert honeysuckles, though this term is shared with the genus "Ancistranthus", and is something of a misnomer as true honeysuckles (genus "Lonicera") belong to the family Caprifoliaceae. "Anisacanthus" species are sometimes cultivated for use in xeriscaping.

Ankylopollexia Ankylopollexia is an extinct clade of dinosaurs within the order Ornithischia that lived from the Late Jurassic to the Late Cretaceous. It is considered a more derived clade of iguanodontians and contains the subgroup Styracosterna and Hadrosauriformes. The name stems from the Greek word, “ankylos”, meaning stiff, fused, and the Latin word, “pollex”, meaning thumb. Originally described in 1986 by Sereno, this most likely synapomorphic feature of a conical thumb spine defines the clade. Many ankylopollexians have not yet been placed in the phylogeny because of the lack of data on the specimens or simply just not analyzed yet. One of the most famous and most derived members of the Ankylopollexia clade is the "Iguanodon".

Cranopsis The Latin word Cranopsis has been used to name animal genera of frogs, mollusks and branchiopods. "Cranopsis" (Cope 1875), was used for an anuran, and is a junior homonym of "Cranopsis" (Adams 1860), for a mollusk; and "Cranopsis" (Dall 1871), for a branchiopod. "Cranopsis" currently describes a mollusk genus in the family Fissurellidae.

Ptyctodontida The ptyctodontids ("folded-teeth") are placoderms of the order Ptyctodontida, containing the family Ptyctodontidae. With their big heads, big eyes, reduced armor and long bodies, the ptyctodontids bore a superficial resemblance to modern day chimaeras (Holocephali). Their armor was reduced to a pattern of small plates around the head and neck. Like the extinct and related acanthothoracids, and the living and unrelated holocephalians, most of the ptyctodontids are thought to have lived near the sea bottom and preyed on shellfish.

Ankylopoda Ankylopoda is a clade that contains turtles and lepidosaurs (Tuatara, lizards and snakes) and their fossil relatives. This clade is supported based on microRNAs as well as the fossil record. Stem-turtles and lepidosaurs have unique skull elements and features not seen in archosaurs (represented by extant crocodilians and birds).

Baurusuchidae Baurusuchidae is a Gondwanan family of mesoeucrocodylians that lived during the Late Cretaceous. It is a group of terrestrial hypercarnivorous crocodilians from South America (Argentina and Brazil) and possibly Pakistan. Baurusuchidae has been defined as a clade containing the most recent common ancestor of "Baurusuchus" and "Stratiotosuchus" and all of its descendants. It may, however, be polyphyletic, as recent phylogenetic analyses have placed "Baurusuchus" within Notosuchia and other baurusuchids within the more distantly related clade Sebecia. A recent study of the family finds it monophyletic by including the South American genera "Baurusuchus", "Cynodontosuchus", "Pissarrachampsa", "Stratiotosuchus", and "Wargosuchus". Other traditional baurusuchids like "Pabwehshi" are excluded. The recently named "Campinasuchus" is also included in the family. Baurusuchids have been placed in the suborder Baurusuchia, and two subfamilies have been proposed: Baurusuchinae and Pissarrachampsinae.

Acleistorhinidae Acleistorhinidae is an extinct family of Early Permian-aged (Artinskian to Kungurian stage) lanthanosuchoid parareptiles. Presently, the clade consists of only two taxa, "Colobomycter" and "Acleistorhinus", both collected from the Permian of Oklahoma. Sister taxa include "Chalcosaurus", "Lanthaniscus" and "Lanthanosuchus".

Harranahynchus Harranahynchus is an extinct genus of sclerorhynchid (Family Sclerorhynchidae) sawfish from the late Maastrichtian deposits of the Muwaqqar Chalk Marl Formation of Harrana in Jordan. The genus is so far represented by a single species, "Harranahynchus minutadens" and named after its minute rostral and dental battery teeth that do not exceed two millimeters in length, a size that is significantly smaller than the rostral teeth of any other modern or extinct sawfish species. Harranahynchids were medium-sized benthic predators around 2-2.5 meters in length and lived in the shallow offshore subtropical marine waters of the southern Tethys Ocean alongside other sclerohynchid sawfishes such as "Schizorhiza stromeri" Weiler, 1930.

Labyrinthodontia Labyrinthodontia (Greek, "maze-toothed") is an extinct amphibian subclass, which constituted some of the dominant animals of late Paleozoic and early Mesozoic eras (about 390 to 150 million years ago). The group evolved from lobe-finned fishes in the Devonian and is ancestral to all extant landliving vertebrates. As such it constitutes an evolutionary grade (a paraphyletic group) rather than a natural group (clade). The name describes the pattern of infolding of the dentin and enamel of the teeth, which are often the only part of the creatures that fossilize. They are also distinguished by a heavily armoured skull roof (hence the older name "Stegocephalia"), and complex vertebrae, the structure of which is useful in older classifications of the group.

Hybodontiformes Hybodontiformes, also called hybodonts, are an extinct subset of Elasmobranchii (sharks, skates and rays) which existed from the Devonian to the Miocene. They form the group of sharks closest to neoselachians, the clade of modern sharks and rays. Hybodonts were named and are distinguished based on their conical tooth shape. They comprised the main group of Jurassic sharks in Europe and North America. They survived into the Late Cretaceous before going extinct, possibly due to competition from other sharks, though forms like "Miosynechodus" endured as recently as the Miocene. "Lonchidion" was one of the last hybodonts— its distinctive serrated fine spines occur in freshwater deposits from Wyoming alongside the fossils of the last dinosaurs, including "Tyrannosaurus rex" and "Triceratops".Hybodontiformes are identified in the fossil record predominantly based on distinct teeth and fin spines. They were known to live in both fresh and salt water environments.

Acristavus Acristavus is a genus of saurolophine dinosaur. Fossils have been found from the Campanian Two Medicine Formation in Montana and Wahweap Formation in Utah, United States. The type species "A. gagslarsoni" was named in 2011. Unlike nearly all hadrosaurids except "Edmontosaurus", "Acristavus" lacked ornamentation on its skull. The discovery of "Acristavus" is paleontologically significant because it supports the position that the ancestor of all hadrosaurids did not possess cranial ornamentation, and that ornamentation was an adaptation that later arose interdependently in the subfamilies Saurolophinae and Lambeosaurinae. It is closely related to "Brachylophosaurus" and "Maiasaura", and was assigned to a new clade called Brachylophosaurini.

Hoyalacerta Hoyalacerta is an extinct genus of lizard known from the type species Hoyalacerta sanzi, which is from the Early Cretaceous Las Hoyas fossil site in Spain. "Hoyalacerta" was named in 1999 and is considered either a member of the group Iguania or a stem squamate, meaning that it lies outside the squamate crown group that includes all living lizards and snakes. "Hoyalacerta" is a small lizard with an elongated body and short limbs. It is thought to have spent most of its time on the ground. Several other lizards are also known from Las Hoyas, including "Meyasaurus" (thought to have lived near the water), "Scandensia" (thought to be a climber), and "Jucaraseps" (which, like "Hoyalacerta", probably lived on the ground away from water). Features of "Hoyalacerta" that distinguish it from other Las Hoyas lizards include smooth skull bones, simple cone-shaped teeth, and short limbs relative to body length.

Disinae Disinae is a subtribe of orchids that has been differently defined and placed in the two classification systems that are currently in use for orchids. "Genera Orchidacearum", which is currently the definitive work on orchid taxonomy, delimits Disinae as consisting of two closely related genera, "Disa" and "Schizodium", and it places Disinae in the mostly African tribe Diseae, along with four other subtribes: Brownleeinae, Huttonaeinae, Coryciinae, and Satyriinae. In the classification for orchids that was published by Chase et alii in 2015, "Schizodium" was placed in synonymy under "Disa", while "Pachites" and "Huttonaea" were transferred to Disinae. In "Genera Orchidacearum", "Pachites" and "Satyrium" form the subtribe Satyriinae, and "Huttonaea" is the sole genus in the subtribe Huttonaeinae. The transfer of "Pachites" and "Huttonaea" to Disinae by Chase et alii (2015) was done with considerable doubt, and was based upon uncertainty about the relationships of these two genera. In 2009, a molecular phylogenetic study found only weak statistical support for a sister relationship between "Huttonaea" and "Disa".
