Lesson plan
Chriacus
Chriacus is an extinct genus of placental mammals that lived in what is now North America during the Paleocene and early Eocene epochs (Puercan through Wasatchian faunal ages). In life, members of the genus may have looked and lived in ways similar to coatimundis, though they were not closely related to any living mammal. Like many early Cenozoic mammals, its relationships are uncertain, with possible affinities to ungulates or Ferae (carnivorans and their relatives). Chriacus and similar Paleocene-Eocene mammals are generally known as arctocyonids, though it is unclear whether different arctocyonids are actually related to each other.
