Fossil taxa described in 1882

Edaphosaurus (, meaning "pavement lizard" for dense clusters of its teeth) is a genus of extinct edaphosaurid synapsids that lived in what is now North America and Europe around 303.4 to 272.5 million years ago, during the Late Carboniferous to Early Permian. The American paleontologist Edward Drinker Cope first described Edaphosaurus in 1882, naming it for the "dental pavement" on both the upper and lower jaws, from the Greek ' ("ground"; also "pavement") and (') ("lizard").

Pantolambda (Greek: "all" (pantos), "lambda" (lambda), in a reference to the shape of upper premolars, similar to the Greek letter lambda) is an extinct genus of Paleocene pantodont mammal. Pantolambda lived during the middle Paleocene, and has been found both in Asia and North America.

Plioplatecarpus is a genus of mosasaur lizard. Like all mosasaurs, it lived in the late Cretaceous period, about 82-68 million years ago.

Psittacotherium ("parrot beast") is an extinct genus of taeniodonts from extinct tribe Psittacotheriini within subfamily Stylinodontinae and family Stylinodontidae, that lived in North America from early to late Paleocene. With a weight between and , and length of , it had similar size of a large dog.

Taeniolabis ("banded incisor") is a genus of extinct multituberculate mammal from the Paleocene of North America.

Heptodon is an extinct genus of tapir-type herbivore of the family Helaletidae endemic to North America during the Early Eocene. It lived from 50.3—48.6 mya, existing for approximately .

Diacodexis is an extinct genus of small herbivorous mammals belonging to the family Diacodexeidae that lived in North America and Europe from 55.4 mya to 46.2 mya, existing for approximately .

Protypotherium is an extinct genus of notoungulate mammals native to South America during the Oligocene and Miocene epochs. A number of closely related animals date back further, to the Eocene. Fossils of Protypotherium have been found in the Deseadan Fray Bentos Formation of Uruguay, Muyu Huasi and Nazareno Formations of Bolivia, Cura-Mallín and Río Frías Formations of Chile, and Santa Cruz, Salicas, Ituzaingó, Aisol, Cerro Azul, Cerro Bandera, Cerro Boleadoras, Chichinales, Sarmiento and Collón Curá Formations of Argentina.

Meniscoessus is a genus of extinct multituberculates from the Upper Cretaceous Period that lived in North America.

Acheloma (also known as Trematops milleri) is an extinct genus of temnospondyl that lived during the Early Permian. The type species is A. cumminsi.

Thecospondylus (THEEK-o-SPON-di-lus, "sheath vertebra") is a dubious genus of dinosaur from the Early Cretaceous of England. Scientists are unsure as to whether Thecospondylus was a saurischian or an ornithischian.

Echinognathus is a genus of eurypterid, an extinct group of aquatic arthropods. The type and only species of Echinognathus, E. clevelandi, is known from deposits of Late Ordovician age in the United States. The generic name is derived from the Neo-Latin echino- ("spiny") and the Greek gnáthos ("jaw"), in reference to a spiny endognathary (used to handle food) appendage part of the fossil type material.

Polysternon is a genus of turtles in the extinct family Bothremydidae. It was described by Portis in 1882, and contains the species P. provinciale (originally placed in the genus Pleurosternon), which existed during the Cretaceous of what is now France and a new species, P. isonae, from the Late Maastrichtian of Spain.

Ectocion (sometimes Ectocyon) is an extinct genus of placental mammals of the family Phenacodontidae. The genus was earlier classified as Gidleyina (Simpson 1935) and Prosthecion (Patterson and West 1973) It reached 6 to 12 kg and was similar in size and morphology to Copecion. Both these herbivorous ungulates likely occupied similar ecological niches.

Palmoxylon, also called petrified palmwood, is an extinct genus of palm named from petrified wood found around the world.

Lucilina is a genus of polyplacophoran molluscs. It includes species known from fossil remains, as well as living species. It is often considered a subgenus of Tonicia.
