Interatheriidae

Interatheriidae is an extinct family of notoungulate mammals from South America. Interatheriids are known from the Late Paleocene or Eocene (Mustersan) to the Late Miocene (Huayquerian).[1][2] These animals were principally small-sized, occupying a habitat like hares, marmots and vizcachas. The majority were very small, like rodents. This was a group that lasted a long time, from the Paleocene to the last of the Miocene.

Subfamilies and Genera

  • Munyizia

  • Antepithecus
  • Guilielmoscottia
  • Notopithecus
  • Transpithecus

Interatheriidae is one of the mammal groups that best represent the fauna from the Santa Cruz Formation. Particularly Protypotherium with three species is characteristic of the formation: Protypotherium australe, P. praerutilum and P. attenuatum. Another well-known genus is Interatherium, particularly well represented by I. robustum.
