Fossil taxa described in 1871

Daira speciosa is an extinct species of crab that lived in the Paratethys sea during the Miocene period. It was up to 4 centimetres (1.6 in) long.

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.

The Asian or Asiatic ostrich (Struthio asiaticus), is an extinct species of ostrich that lived during the Neogene period on the Indian subcontinent.

Anotodus is an extinct genus of thresher sharks that lived during the Neogene. It contains one valid species, Anotodus retroflexus, which has been found in North America, South America, Europe, and Australia.

Glossochelys is an extinct genus of sea turtles from the Pancheloniidae that has been discovered in Eocene (Ypresian) deposits in Harwich, England (London Clay Formation) that was first described as a species of Lytoloma in 1842. The type species, G. planimentum, was described as a separate species in 1871 by Harry Seeley. It was possibly the same animal as Euclastes or Erquelinnesia.

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 monotremes and therians with no living descendants.

Bathysuchus ("deep water crocodile") is an extinct genus of teleosaurid thalattosuchian from Late Jurassic (Kimmeridgian) deep water marine deposits in England and France. Bathysuchus displays features that suggest it was more pelagic than other teleosaurids (along with its close relatives within the Aeolodontinae), including smoother skull bones and reduced armour plating, similar to the fully marine metriorhynchids. This was possibly an adaptation to rising sea levels during the Kimmeridgian, as its earlier relatives such as Teleosaurus were suited for shallow coasts and lagoon environments.

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.

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.

Miocorvus larteti is an extinct species of corvid bird from the Miocene of Europe. It is the only species in the genus Miocorvus.
