Fossil taxa described in 1871

Archaeopteris is an extinct genus of progymnosperm tree with fern-like leaves. A useful index fossil, this tree is found in strata dating from the Upper Devonian to Lower Carboniferous (), the oldest fossils being 385 million years old, and had global distribution.

Struthiosaurus (Latin struthio = ostrich + Greek sauros = lizard) is a genus of nodosaurid dinosaurs from the Late Cretaceous period (Santonian-Maastrichtian) of Austria, Romania, France, and possibly Hungary. It was a small dinosaur, measuring in length and weighing .

Hyrachyus (from Hyrax and "pig") is an extinct genus of perissodactyl mammal that lived in Eocene Europe, North America, and Asia. Its remains have also been found in Jamaica. It is closely related to Lophiodon.

Vulpavus ("ancestor of foxes") is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from the early to middle Eocene.

Trogosus is an extinct genus of tillodont mammal. Fossils have been found in Wyoming, California, and British Columbia, and date from the Eocene between 54.8 and 33.7 million years ago.

Phlegethontia is an extinct genus of aïstopod tetrapodomorphs from the Carboniferous and Permian periods of Europe and North America. upright|thumb|left|Early restoration of P. longissima

Amphilestes is a genus of extinct eutriconodont mammal from the Middle Jurassic of the United Kingdom. It was one of the first Mesozoic mammals discovered and described.

Bolodon is a genus of extinct mammal from the Lower Cretaceous of Europe and North America. It was a member of the extinct order of Multituberculata and belongs to the suborder Plagiaulacida and family Plagiaulacidae.

Alligatorium is an extinct genus of atoposaurid crocodylomorph from Late Jurassic marine deposits in France.

Colosteus is an extinct genus of colosteid tetrapod from the Late Carboniferous (late Westphalian stage) of Ohio. Its remains have been found at the Linton site in Saline Township, Ohio, where it is one of the most common tetrapods, and at the Five Points site in Mahoning County, Ohio. It was an elongate, aquatic form with a flattened and pointed head, greatly reduced limbs, two premaxillary tusks, and heavy scalation. It would have reached about 1 m (3.2 ft) in length.

Ornithostoma (meaning "bird mouth") is a genus of pterodactyloid pterosaur that lived during the Early Cretaceous period (Albian stage) of Europe, around 110 million years ago. Ornithostoma was once thought to have been a senior synonym of the pteranodontid Pteranodon due to its toothless anatomy and prior naming.

Sinopa ("swift fox") is an extinct genus of placental mammals from extinct clade Sinopinae within extinct order Hyaenodonta, that lived in North America and Asia from the early to middle Eocene.

Peramus is an extinct genus of cladotherian mammal. It lived in the Late Jurassic and Early Cretaceous of Europe and North Africa.

Batrachiderpeton is an extinct genus of nectridean tetrapodomorphs within the family Diplocaulidae; it was a basal member of the family. The type species is B. reticulatum and was found in a coal field in Northumberland, England at a locality that also yields the remains of Anthracosaurus russelli. A second species is also known: B. lineatum.

Diopecephalus is a genus of pterodactyloid pterosaur from the Lower Tithonian (Upper Jurassic) of the Lithographic Limestone, Bavaria, Germany. The type and only species is D. kochi, although the name has been applied to Pterodactylus longicollum, with longicollum erroneously listed as the type species. thumb|Juvenile type specimen

Parotodus, commonly known as the false-toothed mako shark (or false mako shark), is an extinct genus of mackerel shark that lived approximately 53 to one million years ago during the Eocene and Pleistocene epochs. Its teeth, which are found worldwide, are often prized by fossil collectors due to their rarity. The scarcity of fossils is because Parotodus likely primarily inhabited open oceans far away from the continents. While the placement of Parotodus with the Lamniformes has been debated, most researchers agree it was probably a member of a now extinct shark clade, either a otodontid or a

Amblotherium is an extinct genus of Late Jurassic and Early Cretaceous mammal. The type species Amblotherium pusillum is from the Lulworth Formation of southern England, while the referred species Amblotherium gracile is from stratigraphic zones 2, 3 and 5 of the Morrison Formation of the US.

Sphenodiscus is an extinct genus of acanthoceratacean ammonite. The genus has been found from many continents and is thought to have had a large global distribution during the Maastrichtian stage of the Late Cretaceous. It was one of the last ammonoids to have evolved before the entire subclass became extinct during the Paleocene, which was directly after the Cretaceous–Paleogene extinction event.

Achyrodon is an extinct genus of mammal from the Berriasian epoch of Early Cretaceous southern England. The taxon was first described by Richard Owen in 1871 for teeth from the Lulworth Formation. The taxon has been considered a synonym of co-existing Amblotherium pusillum, but can be distinguished by differences in the dental anatomy and an overall smaller size. Achyrodon was closely related to co-existing genus Phascolestes and the slightly younger European form Crusafontia, and together they make up the subfamily Kurtodontinae within Dryolestidae, a family of early mammals between modern mo

Zatomus is an extinct genus of pseudosuchian from the Late Triassic. Fossil remains have been found in North Carolina, United States. It is classified as a rauisuchian, a type of large carnivorous thecodontian archosaur.
