Pholidota is an order of placental mammals in the Pholidotamorpha clade. A member of this order is called a pholidotan or a pangolin. They are distributed throughout Africa, the Indian subcontinent and southeast Asia, and are usually found in habitats such as savannas, forests, grasslands and shrublands. Pholidotans range in size from the giant pangolin, at 30 kg (66 lb) and 68 cm (27 in) in length, to the tree pangolin, at only 2.3 kg (5.1 lb) and 34 cm (13 in) in length. They have large, hardened, keratin scales which cover the entirety of the body surface, and long claws which they use for digging or climbing trees. Most species are nocturnal and feed primarily on ants and termites, though other insects may also be taken. Despite only a few pholidotans having population estimates, all eight species are classified as threatened by the IUCN Red List, with three being classified as Critically endangered, largely due to intensive poaching of their keratin scales. [1] [2]
The eight extant species of Pholidota are split into three genera within three subfamilies: Maninae (Asian pangolin), Phatagininae (African tree pangolin) and Smutsiinae (African ground pangolin). Manidae is the only extant family within the Pholidota order, as the other three families— Eurotamandua , Patriomanidae , and Eomanis —have gone entirely extinct. As such, around a dozen or more extinct species have been described, though the exact categorization and number is not fixed due to ongoing research. [1]

In addition to extant species, multiple extinct species have been described and classified into Pholidota. They are placed into three extinct families: Eomanis , Patriomanidae and Eurotamandua , as well as the extant family Manidae. However, the genus Necromanis is placed as incertae sedis within the pholidotid superfamily Manoidea, together with the families Manidae and Patriomanidae. The species listed here are mainly based off the 2019 reference work Pangolins: Science, Society and Conservation, unless otherwise cited. Where available, the temporal range of each species will be given in millions of years before the present time (mya). This list only includes extinct species that went extinct during prehistoric times. [17] [1]

Pangolins, sometimes known as scaly anteaters, are mammals of the order Pholidota. The one extant family, the Manidae, has three genera: Manis, Phataginus, and Smutsia. Manis comprises four species found in Asia, while Phataginus and Smutsia include two species each, all found in sub-Saharan Africa. These species range in size from 30 to 100 cm. Several extinct pangolin species are also known. In September 2023, nine species were reported.
The ground pangolin, also known as Temminck's pangolin, Cape pangolin or steppe pangolin is a species of pangolin from genus Smutsia of subfamily Smutsiinae the within family Manidae. It is one of four species of pangolins which can be found in Africa, and the only one in southern and eastern Africa. The animal was named for the Dutch zoologist Coenraad Jacob Temminck.
Manis ("spirit") is a genus of South Asian and East Asian pangolins, the Asiatic pangolins, from subfamily Maninae, within family Manidae.
Manidae ("spirits") is the only extant family of pangolins. This family comprises three genera, as well as the extinct Fayum pangolin.
The giant pangolin is a species of pangolin from genus Smutsia of subfamily Smutsiinae within the family Manidae. It is the largest living species of pangolins. Members of the species inhabit Africa with a range stretching along the equator from West Africa to Uganda. It subsists almost entirely on ants and termites.
Necromanis is an extinct genus of pangolin from superfamily Manoidea. It lived from the middle Oligocene to middle Miocene in Europe. It was originally placed within family Manidae, but was eventually removed from it as more fossil pholidotids from outside that family were found and studied more extensively. Currently, Necromanis is placed as incertae sedis within the pholidotid superfamily Manoidea, together with the families Manidae and Patriomanidae.
The long-tailed pangolin, also called the African black-bellied pangolin or ipi, is a diurnal, arboreal pangolin species belonging to the family Manidae, in the order Pholidota. They feed on ants rather than termites. The common names for this species stem from physical characteristics, such as the extremely long tail or the dark hairs that cover the underside of their bodies and limbs. Pangolin comes from the Malay word pengguling, meaning “something that rolls up”.
The tree pangolin is one of eight extant species of pangolins, and is native to equatorial Africa. Also known as the white-bellied pangolin or three-cusped pangolin, it is the most common of the African forest pangolins.
Escavadodon is an extinct genus of pangolin-like myrmecophagous placental mammals of extinct monotypic family Escavadodontidae within extinct order Palaeanodonta, that lived in North America during the middle Paleocene. It contains a single species, Escavadodon zygus, recovered from the Nacimiento Formation of New Mexico.
African tree pangolin (Phataginus) is a genus of African pangolins from subfamily small African pangolins (Phatagininae), within family Manidae. Its members are the more arboreal of the African pangolins.
African ground pangolin is a genus of pangolins from subfamily Smutsiinae within family Manidae. It was formerly considered a subgenus of genus Manis. Its members are the more terrestrial of the African pangolins. In past, this genus was also present in Europe.
Patriomanis is an extinct genus of pangolin from extinct family Patriomanidae. It lived from the late Eocene to early Oligocene of North America and it currently represents the only pangolin known from the Western Hemisphere. The genus contains one species, P. americana, which is known from six specimens, mostly from the Chadronian White River Formation of Wyoming. It had long digits and a prehensile tail, suggesting that it was arboreal, and its jaw was capable of opening wider than modern pangolins. Its ears and the hair between its scales were also longer than modern pangolins.
The pangolin trade is the illegal poaching, trafficking, and sale of pangolins, parts of pangolins, or pangolin-derived products on the black market. Pangolins are believed to be the world's most trafficked mammal, accounting for as much as 20% of all illegal wildlife trade. According to the International Union for Conservation of Nature (IUCN), more than a million pangolins were poached in the decade prior to 2014.
Palaeanodonta is an extinct clade of stem-pangolins. They were insectivorous (myrmecophagous), possibly fossorial, and lived from the middle Paleocene to early Oligocene in North America, Europe and Asia. While the taxonomic grouping of Palaeanodonta has been debated, it is widely thought that they are a sister group to pangolins.
Patriomanidae is an extinct family of pangolins from superfamily Manoidea that includes two extinct genera Patriomanis and Cryptomanis. Their fossils are found in Asia and North America.
Pholidotamorpha is a clade of placental mammals from mirorder Ferae that includes the order Pholidota and extinct order Palaeanodonta.
Eupholidota is a suborder of pangolins that includes two superfamilies: extant Manoidea and extinct Eomanoidea.
Manoidea ("spirits") is a superfamily of pangolins from suborder Eupholidota that includes extant family Manidae, extinct family Patriomanidae and extinct genus Necromanis.
Smutsia olteniensis is an extinct species of pangolins from genus Smutsia of subfamily Smutsiinae within family Manidae. Fossilized remains of the species were found in Romania, providing evidence regarding the existence of pangolins in Europe during the Plio-Pleistocene period.
Cryptomanis is an extinct genus of pangolin from extinct family Patriomanidae. The genus is only known from the holotype specimen from middle Eocene deposits from Inner Mongolia, China. The holotype, AMNH 26140, was for years labeled as an unnamed pangolin in the fossil collection for decades. The remains consist of an incomplete postcranial specimen, with nearly complete hind limbs, an incomplete pelvis, a complete lumbar series from an incomplete vertebral column, numerous fragmentary remains of rib and sternal bones, a fragmentary scapula, and partially preserved forelimbs. Based on the femural length Cryptomanis was comparable in size to the modern Sunda pangolin.
