The family Alligatoridae of crocodylians includes alligators, caimans and their extinct relatives.
Nothofagus, also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America and east and southeast Australia, New Zealand, New Guinea, and New Caledonia. The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules, and pollen, with fossils extending into the late Cretaceous period and occurring in Australia, New Zealand, Antarctica, and South America.
Mecoptera is an order of insects in the superorder Endopterygota with about six hundred species in nine families worldwide. Mecopterans are sometimes called scorpionflies after their largest family, Panorpidae, in which the males have enlarged genitals raised over the body that look similar to the stingers of scorpions, and long beaklike rostra. The Bittacidae, or hangingflies, are another prominent family and are known for their elaborate mating rituals, in which females choose mates based on the quality of gift prey offered to them by the males. A smaller group is the snow scorpionflies, family Boreidae, adults of which are sometimes seen walking on snowfields. In contrast, the majority of species in the order inhabit moist environments in tropical locations.
Hippocamelus is a genus of Cervidae, the deer family. It comprises two extant Andean and two fossil species. The living members are commonly known as the huemul, and the taruca, also known as northern huemul.
Nannochoristidae is a family of scorpionflies with many unusual traits. It is a tiny, relict family with a single extant genus, Nannochorista, with eight species occurring in New Zealand, southeastern Australia, Tasmania, Argentina and Chile. Due to the group's distinctiveness from other scorpionflies, it is sometimes placed in its own order, the Nannomecoptera. Some studies have placed them as the closest living relatives of fleas. Most mecopteran larvae are eruciform, or shaped like caterpillars. Nannochoristid larvae, however, are elateriform, and have elongated and slender bodies. The larvae are aquatic, which is unique among mecopterans. The larvae are predatory, hunting on the beds of shallow streams, primarily on the larvae of aquatic Diptera like chironomids.
The Panorpidae are a family of scorpionflies containing more than 480 species. The family is the largest family in Mecoptera, covering approximately 70% species of the order. Species range between 9–25 mm long.
Eomeropidae is a family of aberrant, flattened scorpionflies represented today by only a single living species, Notiothauma reedi, known from the Nothofagus forests in southern Chile, while all other recognized genera in the family are known only as fossils, with the earliest definitive fossil known from Liassic-aged strata, and the youngest from Paleogene-aged strata.
Theosodon is an extinct genus of litoptern mammal from the Early to Middle Miocene of South America.
Feliformia is a suborder within the order Carnivora consisting of "cat-like" carnivorans, including cats, hyenas, mongooses, viverrids, and related taxa. Feliformia stands in contrast to the other suborder of Carnivora, Caniformia.
In phylogenetics, basal is the direction of the base of a rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa.
Asiatosuchus is an extinct genus of crocodyloid crocodilians that lived in Eurasia during the Paleogene. Many Paleogene crocodilians from Europe and Asia have been attributed to Asiatosuchus since the genus was named in 1940. These species have a generalized crocodilian morphology typified by flat, triangular skulls. The feature that traditionally united these species under the genus Asiatosuchus is a broad connection or symphysis between the two halves of the lower jaw. Recent studies of the evolutionary relationships of early crocodilians along with closer examinations of the morphology of fossil specimens suggest that only the first named species of Asiatosuchus, A. grangeri from the Eocene of Mongolia, belongs in the genus. Most species are now regarded as nomina dubia or "dubious names", meaning that their type specimens lack the unique anatomical features necessary to justify their classification as distinct species. Other species such as "A." germanicus and "A." depressifrons are still considered valid species, but they do not form an evolutionary grouping with A. grangeri that would warrant them being placed together in the genus Asiatosuchus.
Jurassipanorpa is a genus of fossil scorpionfly containing two species described in 2014 from the Jiulongshan Formation of Inner Mongolia, China. The two species, J. impuctata and J. sticta, lived in the late Middle Jurassic period. Upon description, they were claimed to represent the oldest known representatives of the scorpionfly family Panorpidae, but this was later questioned.

2015 in paleoentomology is a list of new fossil insect taxa that were described during the year 2016, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
Austropanorpa is an extinct genus of scorpionfly. It is the only member of the family Austropanorpidae. The type species, A. australis was described by Edgar Riek in 1952 based on two incomplete forewings from the Redbank Plains Formation of Queensland, of probable Eocene age, and was assigned to Panorpidae. Later, it was recognised as distinctive enough to be assigned to its own monotypic family by Rainer Willman in 1977. In 2018 the species "Orthophlebia" martynovae from the Early Jurassic (Toarcian) aged Cheremkhovo Formation near Lake Baikal in Siberia, described by Irina Sukacheva in 1985, was recognised as belonging to the genus. The genus is distinguished from other mecopterans by having nine branched radial sectors and four veins in the medial sector of both wings, as opposed to living panorpoids which are typically 5 and rarely 6 branched.
Englathauma is an extinct genus of scorpionfly. It is the only member of the family Englathaumatidae. It is known from two species, E. crabbi, and E. mellisha. Both species are known from the Weald Clay of the United Kingdom, dating to the Barremian stage of the Early Cretaceous. The family had been a nomen nudum since the death of the lead author of the paper Victor G. Novokshonov, in 2003, until the paper was published in 2016. The well sclerotized wings suggest that they were used as cover to protect the body rather than for flight, similar to the living Notiothauma.
Worcestobia is an extinct genus of scorpionfly. It is the only member of the family Worcestobiidae. It was described to contain two species originally assigned to Orthophlebia. Worcestobia gigantea was originally described by Robert John Tillyard in 1933 for NHMUK I. 11102 a hindwing found in the Rhaetian aged Lilstock Formation near Strensham, Worcestershire, United Kingdom The other species, Worcestobia haradai was described in 1991 from KMNH IP 000,002 a forewing found in the Carnian aged Momonoki Formation in a mine near Okuhata, Yamaguchi Prefecture, Japan. It is distinguished from other members of Panorpoidea by "the forking of Rs2 into two long veins Rs2a and Rs2b"
Orthophlebiidae is an extinct family of scorpionflies known from the Triassic to Cretaceous, belonging to the superfamily Panorpoidea. The family is poorly defined and is probably paraphyletic, representing many primitive members of Panorpoidea with most species only known from isolated wings, and has such been considered a wastebasket taxon.
Protorthophlebia is an extinct genus of scorpionflies, known from the Triassic and Jurassic periods of Eurasia. It was originally considered a member of the family Orthophlebiidae, but was later placed as the only genus within the family Protorthophlebiidae within the superfamily Panorpoidea.
The paleofauna of the Eocene Okanagan Highlands is comprised of Early Eocene arthropods, vertebrates, plus rare nematodes and molluscs found in geological formations of the northwestern North American Eocene Okanagan Highlands. The highlands lake bed series' as a whole are considered one of the great Canadian Lagerstätten. The paleofauna represents that of a late Ypresian upland temperate ecosystem immediately after the Paleocene-Eocene thermal maximum, and before the increased cooling of the middle and late Eocene to Oligocene. The fossiliferous deposits of the region were noted as early as 1873, with small amounts of systematic work happening in the 1880-90s on British Columbian sites, and 1920-30s for Washington sites. Focus and more detailed descriptive work on the Okanagan Highlands site started in the last 1970's. Most of the highlands sites are preserved as compression-impression fossils in "shales", but also includes a rare permineralized biota and an amber biota.
