Euarchontoglires

iEuarchontoglires Fossil range: Late Cretaceous - Recent
Ring-tailed Lemurs (Lemur catta)
Scientific classification
Kingdom: Animalia Class: Mammalia Subclass: Eutheria Superorder: Euarchontoglires
Orders
Glires Rodentia Lagomorpha Euarchonta Dermoptera Scandentia Plesiadapiformes† Primates

The Euarchontoglires (synonymous with Supraprimates) are a mammalian superorder based on molecular genetic sequence analyses and retrotransposon presence/absence data, combining the Glires clade, which consists of the Rodentia and the Lagomorpha, with that of the Euarchonta, a clade consisting of the Scandentia, the Primates and the Dermoptera.

The Euarchontoglires probably split from the Laurasiatheria sister group about 85 to 95 million years ago during the Cretaceous. This hypothesis is supported by fossil as well as molecular evidence.

The hypothesized relationship among the Euarchontoglires is as follows:

Euarchontoglires	Glires Rodentia (rodents) Lagomorpha (rabbits, hares, pikas) Euarchonta Scandentia (treeshrews) Dermoptera (flying lemurs) †Plesiadapiformes Primates
