Chriacus

Chriacus is an extinct genus of placental mammals that lived in what is now North America during the Paleocene and early Eocene epochs. 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. Chriacus and similar Paleocene-Eocene mammals are generally known as arctocyonids, though it is unclear whether different arctocyonids are actually related to each other.

Paleobiology
Chriacus were probably omnivores, eating fruit, eggs, insects and small mammals. Climbing adaptations Chriacus has better-preserved fossils than most other Paleocene mammals. The most complete skeleton belongs to an uncertain species (Chriacus sp.) from the Willwood Formation of Wyoming. though it is too different in form to be a direct ancestor. == Classification ==
Classification
Species At least nine species are currently recognized in the genus, consider it a member of the family Oxyclaenidae, a sister group to palaeoryctids and creodonts, while Tabuce et al. (2011) classify it as an arctocyonid, most closely related to Loxolophus, then Arctocyon, and allied to the Mesonychia. This difference mirrors the history of the mammals classified as arctocyonids. They were first considered creodonts (imagined to be the ancestors of modern carnivorans), and then "condylarths" (imagined to be the ancestors of hoofed mammals). Modern studies suggest the confusion is due to the fact that ungulates, carnivorans, and creodonts are related groups, and flesh-eating lineages and adaptations evolved within each of them. Chriacus lies somewhere within the range of their early relatives. ==References==
