Herpetotheriidae
Template:Short description Template:Automatic taxobox
Herpetotheriidae is an extinct family of metatherians, closely related to marsupials.Template:Sfn Species of this family are generally reconstructed as terrestrial, and are considered morphologically similar to modern opossums.Template:Sfn They are suggested to have been insectivores.[1] Fossils of herpetotheriids come from North America, Asia, Europe, Africa, and perhaps South America. The oldest representative is Maastrichtidelphys from the latest Cretaceous (Maastrichtian) of the NetherlandsTemplate:Sfnm and the youngest member is Amphiperatherium from the Middle Miocene of Europe.Template:Sfn The group has been suggested to be paraphyletic, with an analysis of petrosal anatomy finding that North American Herpetotherium was more closely related to marsupials than the European Peratherium and Amphiperatherium.[2]
The family includes the following genera:Template:Sfn
- Amphiperatherium (Early Eocene to Middle Miocene, Europe; synonyms: Oxygomphius, Microtarsioides, Ceciliolemur)
- Asiadidelphis (Late Eocene to Early Oligocene, Kazakhstan and Pakistan)Template:Sfn
- Copedelphys (Late Eocene to Early Oligocene, North America)
- Entomacodon (Middle Eocene, North America; synonym: Centracodon)
- Golerdelphys (Late Paleocene, North America)[3]
- Galatiadelphys (Middle Eocene, Turkey)
- Herpetotherium (Early Eocene to Middle Miocene, North America)
- Maastrichtidelphys (Maastrichtian, Europe)Template:Sfn
- Nortedelphys (Lancian, North America)Template:Sfn
- Peratherium (Early Eocene to Early Miocene, Europe; Early Oligocene, Egypt, Oman;Template:Sfn synonyms: Alacodon, Qatranitherium)
- Swaindelphys (Early Paleocene, North America)
- Morotodon (Early to Middle Miocene, Uganda, placement in the family tentative)[4]
The following genera have been placed in the family, but their placement is disputed or obsolete:
- Garatherium (Early Eocene of Algeria) – possibly an adapisoriculid eutherianTemplate:Sfn
- Indodelphis (Early Eocene of India) – originally referred to PeradectidaeTemplate:Sfn
- Jaegeria (Early Eocene of India) – a batTemplate:Sfn
- Rumiodon (Paleogene of Peru) – placement uncertainTemplate:Sfn
