Condylarthra - Wikipedia
Condylarthra is an informal group – previously considered an order – of extinct placental mammals, known primarily from the Paleocene and Eocene epochs. [1] They are considered early, primitive ungulates.
Condylarthra | Definition & Facts | Britannica
Condylarthra, extinct group of mammals that includes the ancestral forms of later, more-advanced ungulates (hoofed placental mammals). The name Condylarthra was once applied to a formal taxonomic order, but it is now used informally to refer to ungulates of the Late Cretaceous and Early Paleogene times.
Primitive Ungulates (“Condylarthra” and Stem Paenungulata)
Africa is probably the most poorly known paleobiogeographic province in the evolutionary history of the primitive ungulates collectively called “Condylarthra.” This is related to the more general problem of the very poor fossil record of mammals in the early Paleogene of Africa.
