Epoicotheriidae ("strange beasts") is an extinct paraphyletic family of insectivorous placental mammals within extinct order Palaeanodonta, that lived in North America, Asia and Europe from the late Paleocene to early Oligocene. [2] Epoicotheriids were fossorial mammals. Late Eocene/early Oligocene genera were highly specialized animals that were convergent with the talpids, golden moles and marsupial mole in the structure of their skulls and forelimbs, and would have had a similar lifestyle as subterranean burrowers. [3]
Epoicotheriidae was named by Simpson in 1927. It was assigned to the Palaeanodonta by Rose (1978) [4] and Carroll (1988).

Ptilodus is a genus of mammals from the extinct order of Multituberculata, and lived during the Paleocene in North America.
Eomanis is the earliest known true pangolin from extinct family Eomanidae within suborder Eupholidota. It lived during the Eocene in Europe. Eomanis fossils found in the Messel Pit in Germany are very similar in size and anatomy to living pangolins of the genus Manis, indicating that pangolins have remained largely unchanged in morphology and behavior for 50 million years. However, unlike modern pangolins, its tail and legs did not bear scales. According to the stomach contents of the excellently preserved Messel specimens, Eomanis’ diet consisted of both insects and plants.
Metacheiromys is an extinct genus of placental mammals from extinct paraphyletic subfamily Metacheiromyinae within extinct paraphyletic family Metacheiromyidae in extinct order Palaeanodonta, that lived in North America from the early to middle Eocene.
Eurotamandua is an extinct genus of mammal from extinct family Eurotamanduidae that lived during the middle Eocene.
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.
Ernanodon is an extinct genus of placental mammal from extinct family Ernanodontidae within extinct order Palaeanodonta, that lived from the middle to late Paleocene in China and Mongolia.
Tillodontia is an extinct suborder of eutherian mammals known from the Early Paleocene to Late Eocene of China, the Late Paleocene to Middle Eocene of North America where they display their maximum species diversity, the Middle Eocene of Pakistan, and the Early Eocene of Europe. Leaving no descendants, they are most closely related to the pantodonts, another extinct group. The tillodonts were medium- to large-sized animals that probably feed on roots and tubers in temperate to subtropical habitats.
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.
Prolimnocyon is an extinct paraphyletic genus of limnocyonid hyaenodonts that lived in Asia and North America during the late Paleocene to middle Eocene. Prolimnocyon chowi is the earliest known member of the hyaenodontid family Limnocyonidae.
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.
Ernanodontidae is an extinct family of myrmecophagous placental mammals within extinct order Palaeanodonta, that lived in Asia from the middle to late Paleocene.
Pholidotamorpha is a clade of placental mammals from mirorder Ferae that includes the order Pholidota and extinct order Palaeanodonta.
Euromanis is one of the earliest known pangolin genera. It lived during the middle Eocene in Europe. Euromanis fossils found in the Messel Pit in Germany. Unlike modern pangolins, it did not bear scales on its body.
Eupholidota is a suborder of pangolins that includes two superfamilies: extant Manoidea and extinct Eomanoidea.
Xenocranium is an extinct monotypic genus of placental mammal from extinct paraphyletic subfamily Epoicotheriinae within extinct paraphyletic family Epoicotheriidae in extinct order Palaeanodonta, that lived in North America during the late Eocene.
Palaeonictinae is an extinct subfamily of placental mammals from extinct family Oxyaenidae, that lived from the late Paleocene to early Eocene of Europe and North America.
Didymictinae is an extinct subfamily of mammals from extinct family Viverravidae, that lived from the early Palaeocene to the middle Eocene in North America and Europe.
Metacheiromyidae is an extinct paraphyletic family of myrmecophagous placental mammals within extinct order Palaeanodonta, that lived in North America and Europe from the late Paleocene to middle Eocene.
Metacheiromyinae is an extinct paraphyletic subfamily of myrmecophagous placental mammals within extinct paraphyletic family Metacheiromyidae in extinct order Palaeanodonta, that lived in North America and Europe from early to middle Eocene.
Epoicotheriinae is an extinct paraphyletic subfamily of insectivorous placental mammals within extinct paraphyletic family Epoicotheriidae in extinct order Palaeanodonta, that lived in North America and Europe from the early Eocene to early Oligocene. Epoicotheriins were fossorial mammals. Late Eocene/early Oligocene genera were highly specialized animals that were convergent with the talpids, golden moles and marsupial mole in the structure of their skulls and forelimbs, and would have had a similar lifestyle as subterranean burrowers.
