Archonta

Archonta
	Olive baboon
Scientific classification
Kingdom:	Animalia
Phylum:	Chordata
Class:	Mammalia
Subclass:	Placentalia
Superorder:	Archonta (disputed)
Orders
	Primates; Plesiadapiformes (extinct); Scandentia; Dermoptera; Chiroptera (dropped);

The Archonta are a now-abandoned group of mammals, considered a superorder in some classifications, which consists of these orders:

Primates
Plesiadapiformes (extinct primate-like archontans)
Scandentia (treeshrews)
Dermoptera (colugos)

While bats were traditionally included in the Archonta, recent genetic analysis has suggested that bats actually belong in Laurasiatheria.[1] A revised category, Euarchonta, excluding bats, has been proposed.[2][3]

This taxon may have arisen in the Early Cretaceous (more than 100 million years ago), so other models may explain mammalian evolution besides an explosive radiation from a single surviving lineage following the Cretaceous-Paleogene extinction of the Mesozoic megafauna,[4] such as a series of prior radiations related to the breakup of Gondwana and Laurasia allowing for more survivors.[5][6]
