Euarchontoglires

From Wikipedia, the free encyclopedia

Euarchontoglires
Fossil range: Late Cretaceous - Recent

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
