Pantolestans

Kopidodon is an extinct genus of placental mammals from subfamily Paroxyclaeninae within family Paroxyclaenidae, that lived during the middle Eocene in Germany.

Pantolestidae ("all robbers") is a paraphyletic family of placental mammals from extinct order Pantolesta, that lived in North America, Asia and Europe from the early Paleocene to middle Oligocene. They first appear in North America, whence they spread to Europe and Asia.

Palaeosinopa ("ancient Sinopa") is an extinct genus of semi-aquatic mammals belonging to the subfamily Pantolestinae within family Pantolestidae. Species in this genus lived from the late Paleocene to early Eocene in North America and Europe. Their diet consisted of other aquatic life forms.

Bisonalveus ("animal from Bison Basin") is an extinct genus of placental mammals from family Pentacodontidae, that lived during the middle to late Paleocene. Bisonalveus fossils have been discovered in the upper Great Plains region of North America, including sites in modern-day Wyoming, North Dakota, Montana, and Alberta.

Buxolestes ("robber from Bouxwiller") is an extinct genus of semi-aquatic mammals belonging to the subfamily Pantolestinae within family Pantolestidae. Species in this genus lived during the middle Eocene. They are known from fossils found in the Bracklesham Group and Wittering Formation of England, at the Messel Pit in Germany and in Bouxwiller, France.

Pantolesta ("all robbers") is an extinct order of placental mammals that lived in North America, Asia and Europe from the early Paleocene to middle Oligocene. They are recognized as close relatives of clade Pholidotamorpha (pangolins and palaeanodonts), based on their dental and postcranial similarities, and semi-fossorial adaptations.

Pentacodontidae ("teeth with five points") is an extinct family of placental mammals from extinct order Pantolesta, that lived in North America and Europe from the early to late Paleocene.

Paroxyclaenidae is an extinct family of pantolestan mammals that ranges from the early Eocene to the early Oligocene. Most members of the family are found throughout Europe though the youngest and largest member, Welcommoides, lived in what is now Pakistan. Similar to a large amount of other more basal Cenozoic mammals, their taxonomic placement is not well understood with suggestions ranging from being within Carnivora to within the former order Creodonta. Today, them and Pantolesta as a whole are considered Eutherian mammals that may be a part of another problematic order, Cimolesta.
