The Aral Formation is a geologic formation in Kazakhstan. It preserves fossils dating back to the Neogene period.^[1] Much of its fossils consist of Glires and fish, though cetaceans and cryptobranchid salamanders are also known.

Paleobiota

The Aral Formation has yielded a rich variety of extinct mammals. Many of its mammal fauna consists of the clade Glires with rodents being particularly numerous.^[1]
