The Euarchonta are a proposed

Euarchonta and Glires together form the Euarchontoglires, one of the four eutherian clades.

The current hypothesis, based on molecular clock evidence, suggests that the Euarchonta arose in the late Cretaceous period, about 88 million years ago, and diverged 86.2 million years ago into the groups of tree shrews and Primatomorpha. The latter diverged prior to 79.6 million years into the orders of Primates and colugos.^[10] The earliest fossil species often ascribed to Euarchonta (Purgatorius coracis) dates to the early Paleocene, 65 million years ago,^[11] but one study claims it to be a non-placental eutherian.^[12] Although it is known that Scandentia is one of the most basal clades of Euarchontoglires, the exact phylogenetic position is not yet considered resolved, and it may be a sister of Glires, Primatomorpha or Dermoptera or to all other Euarchontoglires.^{[13][14][15][16]}
