Condylarthra
Order of mammals
Condylarthra, also known as archaic ungulates, is an informal group – previously considered an order – of extinct placental mammals, known primarily from the Paleocene and Eocene epochs. It is now largely considered to be a wastebasket taxon, having served as a dumping ground for classifying ungulates which had not been clearly established as part of either Perissodactyla or Artiodactyla, being composed thus of several unrelated lineages.

Condylarthra, also known as archaic ungulates, is an informal group – previously considered an order – of extinct placental mammals, known primarily from the Paleocene and Eocene epochs. It is now largely considered to be a wastebasket taxon, having served as a dumping ground for classifying ungulates which had not been clearly established as part of either Perissodactyla or Artiodactyla, being composed thus of several unrelated lineages. Spharnotheriodontidae recovered as a family of Litopterna. Additionally, some condylarths, such as Kharmerungulatum, were found to be have been outside of ungulates entirely. Arctocyonidae was recovered as a polyphyletic family of mammals, with the placement within Ferungulata varying between genera.
